How Sedentary Are University Students? A Systematic Review and Meta-Analysis

Disordered eating attitudes and behaviors and intuitive eating by college-going generation status

OBJECTIVE

To examine how disordered eating attitudes and behaviors (DEABs) and intuitive eating (IE) differ between first-generation college students (FGCS) and continuing-generation college students (CGCS).

PARTICIPANTS

A total of 854 college students in 2022.

METHODS

College-going generation was self-reported DEABs and IE were assessed from the Questionnaire on Eating and Weight Patterns-5 and Intuitive Eating scale-2, respectively. Logistic and linear regressions were used to examine associations of college-going generation status with DEABs and IE, respectively.

RESULTS

The predicted probabilities of DEABs were substantial in both FGCS (29.6-53.3%) and CGCS (26.8-50.3%) with no significant differences between FGCS and CGCS. However, FGCS had a lower IE score than CGCS (β = -0.54, 95% CI = -1.10, -0.01) after adjustment for age, sex, ethnicity/race, and body mass index.

CONCLUSION

The differences in eating behaviors by college-going generation status emphasizes the need for inclusive efforts to prevent DEABs while highlighting the need to develop strategies to assist FGCS in practicing IE.

The impact and perceptions of standing desk interventions on movement patterns and physical, mental, and academic outcomes in university students: a scoping review

BACKGROUND

The use of standing desks may reduce sedentary behavior and, in turn, improve other health and academic outcomes. However, the evidence is sparse among university settings. The aim of this scoping review was to identify and map evidence for the effects of standing desk interventions on sedentary behavior and physical, mental, and academic outcomes in university students, as well as instructors and students' perceptions of this type of equipment in the classroom.

METHODS

A scoping review was conducted in accordance with the Joanna Briggs Institute and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Review guidelines. PubMed, Web of Science, Scopus, PsycINFO, PubPsych and ERIC databases were searched for qualitative and quantitative studies from their inception to 2024. Narrative synthesis and network plots were used to summarize the available evidence.

RESULTS

Seventeen studies involving 2886 university students and 163 instructors were included. Fourteen studies were experimental and three were cross-sectional. In seven studies standing desks improved movement patterns (sitting and standing time in the classroom) and in four studies improved mental health outcomes (anxiety, mood, stress, and positive or negative feelings). Four studies analyzed pain and discomfort, one found significant improvements and three found mixed results. Eleven studies analyzed academic and classroom outcomes and seven found significant improvements in the standing desks group and five did not. Additionally, the use of standing desks was accepted and positively perceived by students in ten studies and by instructors in two.

CONCLUSIONS

The implementation of standing desks at university settings could be a behavioral intervention for improving movement patterns and mental health. However, the extant evidence is sparse; further long-term, high-quality trials are needed to draw robust conclusions.

Secular trends in physical fitness and cardiovascular risks among Chinese college students: an analysis of five successive national surveys between 2000 and 2019

Background

With increasing concerns about early-onset cardiovascular diseases, it is essential to understand the distribution of cardiovascular health among young adults. This study aimed to characterize trends in physical fitness and the prevalence of overweight/obesity (OWOB), elevated blood pressure (EBP), and their comorbidity among Chinese college students from 2000 to 2019 and to analyze the changes in their associations and subgroup differences.

Methods

Data were extracted from five cycles of the Chinese National Survey on Students' Constitution and Health (2000-2019), including 241,710 college students aged 19-22. Physical fitness indicator (PFI) was computed using standardized z-scores of forced vital capacity, sit-and-reach, 50-m dash, standing long jump, muscle strength, and endurance running. OWOB was defined as a body mass index ≥25 kg/m2, and EBP as systolic blood pressure ≥140 mmHg and/or diastolic blood pressure ≥90 mmHg. Comorbidity was defined as the co-occurrence of OWOB and EBP. Mixed-effects logistic regression was used to analyze associations, and generalized linear mixed-effects models were applied to examine dose-response relationships.

Findings

The median of college students' PFI deteriorated continuously from -0.16 in 2000 to -1.99 in 2019, with boys experiencing a faster decline than girls. The prevalence of OWOB, EBP, and comorbidity increased significantly from 3.7%, 2.2%, and 0.3% in 2000 to 14.0%, 5.2%, and 1.8% in 2019, respectively, with boys exhibiting higher prevalence than girls. Decreasing PFI levels were significantly associated with the increasing prevalence of OWOB, EBP, and comorbidity, and such associations were strongest in 2019. L-shaped curves were observed for the relationships between PFI and the prevalence of OWOB, EBP, and comorbidity, with stronger associations in boys. Provincial population attributable fraction showed that when improving the PFI levels from low to middle-low or above, college students in Guizhou, Sichuan, and Yunnan provinces exhibited the most reductions in OWOB, EBP, and comorbidity.

Interpretation

Physical fitness among Chinese college students has significantly declined over the past two decades, accompanied by marked increases in the burden of cardiovascular risks. There is an urgent need to increase the focus on college students' health and establish a college-based physical examination system to assess their long-term cardiovascular function.

Funding

The present study was funded by National Key R&D Program of China (Grant No. 2024YFC2707901 to Yi Song), National Natural Science Foundation of China (Grant No. 82273654 to Yi Song), and Beijing Office for Education Sciences Planning (Grant No. BBAA22027 to Yi Song).

Associations of objectively measured physical activity and sedentary behavior with sleep quality in college students

BACKGROUND

Sleep disorders are prevalent in college students and are often exacerbated by academic pressures. Accumulating evidence indicates that physical activity and sedentary behaviors exert divergent effects on sleep quality. This study aimed to investigate the associations of objectively measured physical activity and sedentary behavior with sleep quality in college students. The potential effects of substituting sedentary behavior with physical activity on sleep quality were also examined.

METHODS

This cross-sectional study included 349 college students (age range: 17-25 years; 57.6 % female) recruited from Shanghai, China. Light physical activity (LPA), moderate-to-vigorous physical activity (MVPA), and sedentary behavior were objectively measured using wrist-worn accelerometers for 7 days. Sleep quality was assessed using the Pittsburgh Sleep Quality Index. A single-factor model was used to examine independent associations, whereas an isotemporal substitution model (ISM) was used to estimate the effects of replacing sedentary behavior with physical activity on sleep quality.

RESULTS

Higher levels of LPA (B = -0.007, 95 % CI = -0.013 to -0.001, p < 0.05) and MVPA (B = -0.013, 95 % CI = -0.022 to -0.003, p < 0.05) were associated with better sleep quality. Conversely, sedentary time was negatively associated with sleep quality (B = 0.007, 95 % CI = 0.002 to 0.012, p < 0.05). In the ISM, replacing 30 min of sedentary behavior with an equivalent duration of MVPA was associated with improved sleep quality (B = -0.322, 95 % CI = -0.624 to -0.021, p < 0.05).

CONCLUSIONS

The findings indicated that physical activity was positively associated with sleep quality, whereas sedentary time was negatively associated with sleep quality in college students. Replacing sedentary behavior with an equivalent duration of MVPA positively affected sleep quality.

Differential impacts of jogging and rope skipping in college students in China based on physical test score: a randomized controlled trial baseline indicator comparison in the intervention

Introduction

Studying the differential effects of jogging and rope skipping provides useful insights for teens, adolescents, and even adults to make choices and maintain healthy physical activities, which may also have positive significance for the promotion of public physical fitness and health.

Methods

A total of 92 college students were enrolled in the study and randomly divided into jogging group, rope skipping group and control group. Tests and questionnaires were conducted before and right after the intervention, and a questionnaire survey was conducted again half a year after the intervention.

Results

The results showed that the standing long jump performance and the cardiopulmonary function in the jogging group were significantly improved after the intervention, the average score of standing long jump increased from 72.00 to 76.45 and the mean systolic blood pressure decreased from 125.07 to 121.24 (t = 3.048, 2.139, p = 0.005, 0.041). The scores of 800 or 1,000 meters and the total scores of physical test in the rope skipping group and the control group were decreased significantly. The improvement of standing long jump performance in the jogging group was significantly higher than that in the control group.

Discussion

The main reason for the decline in the rope skipping group may be due to insufficient strength. Jogging differs from rope skipping in terms of muscle focus, arm-swinging style, nature of the exercise, and the associated exercise mood. As a result, after short-term training, jogging has a more positive significance than skipping rope in maintaining and improving physical fitness and cardiopulmonary function. If you want to improve your physical fitness in a shorter period of time, then jog.

Changes in dietary, lifestyle habits and mood in college students during the COVID-19 pandemic: a survey distributed across Greek universities

Introduction: The COVID-19 pandemic had implications on students' life. This study aims to identify positive and negative effects of COVID-19 pandemic on students' life habits with the final goal to promote their general wellbeing.

Methods: An online questionnaire was administered to Greek undergraduate and graduate college students during the COVID-19 quarantine. The impact of the pandemic on the dietary and lifestyle habits were evaluated in 246 participants.

Results: The study revealed that 57.7% of students boosted their fruit and vegetable intake, 43.1% consumed more meals, and 57.7% increased snacking. Breakfast eaters went from 57.7% to 66.6%, and those preparing homemade meals rose to 58.9%. Conversely, 61.4% reported increased sedentary time, 61.8% noted weight gain, and only 71% claimed a medium level of life satisfaction post-pandemic.

Conclusion: Students developed some healthier dietary habits during the pandemic. However, many of them gained weight because of inactivity, adverse dietary behaviors and decreased level of life satisfaction.

Micro-gyms as a catalyst for healthy aging in university and healthcare settings: applications for the Semmelweis-EUniWell Workplace Health Promotion Model Program

Europe is experiencing a significant demographic shift, with aging populations posing economic and social challenges due to increased healthcare costs and a higher prevalence of age-related diseases. Hungary, in particular, faces these challenges acutely due to higher morbidity and mortality rates from a range of chronic age-related diseases and behavioral risk factors. Addressing these issues requires innovative approaches to promote healthy aging. Semmelweis University, the largest healthcare provider and leading health sciences university in the region, is developing a comprehensive healthy aging program. A critical pillar of this program is the Semmelweis-EUniWell Workplace Health Promotion Model Program, a pioneering initiative aimed at tackling unhealthy aging within Hungary's workforce by leveraging the workplace as a platform for health promotion. Central to this program's goal of combating sedentary lifestyles-a significant contributor to age-related health issues-is the innovative use of micro-gyms and motivational interviewing. Micro-gyms, with their compact size and accessibility, provide convenient exercise opportunities, while motivational interviewing fosters intrinsic motivation and personalized counseling to encourage sustained physical activity. Through concerted efforts and innovative approaches, including the implementation of micro-gyms, the Semmelweis-EUniWell Workplace Health Promotion Model Program aims to set a benchmark for workplace health promotion, fostering a healthier and more resilient aging population in Hungary. This program not only enhances the well-being of employees at Semmelweis University and its EUniWell partner institutions but also catalyzes broader transformations in workplace health promotion and healthy aging nationwide.

Measuring health-related quality of life among university students: a scoping review protocol

BACKGROUND

Understanding university students' health-related quality of life (HRQoL) can help propose strategies that support targeted care for this population and identify issues affecting these individuals. Therefore, it is necessary to identify the commonly used instruments and possible study designs for the university population, enabling the standardization of interventions and instruments to evaluate the HRQoL of university students. We aim to conduct a scoping review to identify the main measurement instruments and key characteristics in studies using HRQoL measures among university students. It is also aimed at identifying the foundations for guiding future research priorities.

METHODS

This review will consider original peer-reviewed articles that used any generic HRQoL measurement instruments exclusively used with university students aged 18-59. Validation, qualitative, language translation, or adaptation studies will be excluded. This review will follow the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR). The research will be conducted in five electronic databases (PubMed, Embase, Web of Science, Scopus, and SPORTDiscus). Two reviewers will independently screen records using predefined eligibility criteria and extract data using tables. The extracted data will include specific details about the title, authors, year of publication, HRQoL instrument utilized, participants, intervention design, and critical findings. The results will be presented in a narrative summary with data displayed in tabular and diagrammatic formats.

DISCUSSION

This proposed scoping review aims to provide a comprehensive overview of the existing methods for assessing health-related quality of life in university students. The results will help identify gaps in the literature and establish a foundation for guiding future research priorities.

Strategies and barriers to implementing physically active teaching in universities from the perspective of lecturers: a qualitative study

BACKGROUND

University students accumulate lots of sedentary time without interrupting and comprehensive approaches to reduce time spent sedentary are lacking. The implementation of physically active university teaching needs practicable approaches and the support by lecturers. However, there is little research on which physically activating strategies lecturers actually use and what barriers they become aware to implement these. This exploratory, qualitative study aims to identify physically activating strategies as well as barriers for reducing sitting time and physically active university teaching from the perspective of lecturers.

METHODS

We conducted semi-structured interviews with 16 lecturers to explore potential physically activating strategies in university teaching, assess their degree of utilization, and identify barriers to implementation. The data were analysed by a structured content analysis of the interview transcripts using MAXQDA 2020 software.

RESULTS

Physically activating strategies are hardly known among university lecturers and are seldomly used on a regular and conscious basis. We identified two types of strategies with physically activating measures and teaching methods. Lecturers highlighted two specific types of physically activating measures: physical activity breaks and the use of physically activating furniture. All together, we identified 18 distinct teaching methods (e.g. group work, gallery walk) that integrate learning processes with physical activity in a pedagogical-didactic manner. The main barriers to implementation identified were lack of space, lack of time, students' unwillingness to move; organizational social norms, and lecturers' uncertainty about how to implement these strategies effectively.

CONCLUSIONS

University lecturers are generally unfamiliar with and rarely use physically activating strategies to reduce sedentary behavior in students. However, lecturers identified 18 potential teaching methods that integrate physical activity with pedagogical-didactic principles, offering a new approach to physically active university teaching. These methods present an untapped potential for the low-threshold integration of physical activity and breaks from sitting into university teaching, aligning with "stealth health" strategies that incidentally promote health while assuring a "high-quality education" as the core concern of higher education teaching. Understanding and addressing the barriers to implementation, such as lack of space, time, social and organizational norms, is crucial for the effective planning and implementation of interventions.

Breaking up sitting enhances neurocognitive function which is associated with improved postprandial glucose regulation in healthy adults: A randomized crossover study

BACKGROUND AND AIMS

The glucose-centric hypothesis postulates that glycemic control may influence cognition. While research has examined the effects of breaking up sitting on blood glucose and inhibitory control, few studies have integrated these data and employed event-related potential (ERP) measures to delve into the neuroelectric processes. This study aimed to investigate the effects of breaking up sitting on postprandial blood glucose response, inhibitory control, and P3 component.

METHODS

Eighteen healthy male participants [25 ± 4 years, 23.5 ± 3.2 kg/m² (mean ± SD)] were subjected to 3.5 h uninterrupted sitting (SIT) or with 3 min walking at 6.4 km/h every 30 min (ACTIVE) trials in a randomized crossover design. The Stroop task was administered to assess inhibitory control before and after SIT and ACTIVE trials, and electroencephalography was employed to derive stimulus-elicited P3 component. Finger prick blood glucose levels were collected at baseline, 0.5 h, 1 h, and 3.5 h during the trials.

RESULTS

While no significant differences were found in inhibitory control performances between trials, greater P3 amplitude was found in the ACTIVE trial relative to the SIT trial (p = .041). Lower postprandial blood glucose iAUC was found in ACTIVE trial compared to SIT trial (p = .028), and this was correlated with the elevation of P3 amplitude (r = - 0.521, p = .023).

CONCLUSION

Breaking up sitting acutely facilitates neuroelectric indices of attentional processing, which is associated with the optimal postprandial blood glucose control.

Associations Between Clinical Inflammatory Risk Markers, Body Composition, Heart Rate Variability, and Accelerometer-Assessed Physical Activity in University Students with Overweight and Obesity

This cross-sectional study aimed to identify associations between clinical inflammatory risk markers, body composition, heart rate variability (HRV), and self-reported and objectively assessed physical activity (PA) in university students with overweight and obesity. Seventeen participants (eight females) completed a screening visit following a randomized controlled four-arm crossover trial period with 8 h of uninterrupted prolonged sitting, alternate sitting and standing, continuous standing, and continuous slow walking, respectively. Clinical inflammatory risk markers were obtained from venous blood samples, and PA was assessed using the International Physical Activity Questionnaire (IPAQ-SF) and ActiGraph wGT3X-BT accelerometers. HRV was recorded over 24 h using the Faros 180 Holter electrocardiogram (ECG). White blood cell (WBC) counts were significantly correlated with fat mass (FM; p = 0.03) and visceral adipose tissue (VAT; p = 0.04) and inversely correlated with moderate PA (p = 0.02). Light-intensity PA (LIPA) and moderate-to-vigorous PA (MVPA) were correlated with HRV parameters (p = 0.02), and LIPA was inversely correlated with interleukin-6 (p = 0.003) and c-reactive protein (p = 0.04) during different trial conditions. In university students with overweight and obesity, higher values of FM were negatively correlated with WBC count, and integrating LIPA and MVPA in the students' daily life strengthened their sympathetic-parasympathetic regulation and positively mediated anti-inflammatory mechanisms.

Physical activity: the key to life satisfaction - correlations between physical activity, sedentary lifestyle, and life satisfaction among young adults before and after the COVID-19 pandemic

COVID-19 has fundamentally altered the world, significantly affecting people's health and quality of life. These changes may have impacted young adults' physical activity (PA) and sedentary behavior (SB). This study aims to explore lifestyle changes among young adults, particularly focusing on the relationship between physical activity, sedentary behavior, and life satisfaction before and after the COVID-19 pandemic. To achieve this, we analyzed two surveys carried out in 2018 and 2024. A total of 799 participants were recruited for this age group, with 279 in 2018 and 520 in 2024. We employed T-tests, Pearson's Chi-square tests, Mann-Whitney tests, and ordinal linear regression to uncover associations between physical activity and sitting time across the two periods, alongside various socio-demographic factors and predictors of life satisfaction. Our results reveal notable trends and changes in physical activity levels and sitting times among young adults in Hungary between 2018 and 2024. The most striking changes occurred in IPAQ (International Physical Activity Questionnaire) categorical scores, indicating a shift in activity levels across several demographic groups. The level of physical activity increased for both male and female respondents, residents of county seats and cities, as well as those living in relationships. In 2018, young Hungarian adults who maintained a balance of physical activity-including cycling, some home-based physical work, and limited sitting time-tended to report higher life satisfaction. In 2024, an interesting pattern emerged regarding leisure activities: individuals who engaged in very hard exercise during their free time reported varying levels of life satisfaction. Those who never engaged in very hard exercise or did so only once a week reported lower satisfaction compared to those who exercised daily. This finding aligns with existing research on the mental health benefits of regular intense physical activity. Furthermore, individuals whose physical activity was primarily work-related reported significantly lower life satisfaction compared to those whose physical activity was primarily leisure-related. This suggests that the context of physical activity is crucial in determining its impact on life satisfaction.

The effects of a 12-week moderate-intensity continuous training intervention on depression, anxiety, and stress in sedentary female college students: a focus on negative emotion regulation

Objective

Moderate Intensity Continuous Training (MICT) is recognized as an effective intervention for improving negative affect. However, research on its effects across varying levels of negative mood states in sedentary female college students remains limited. This study aimed to investigate the impact of a 12-week MICT intervention on different levels of negative mood in sedentary female college students.

Methods

A total of 144 participants were randomly assigned to two groups, each consisting of 72 individuals. The participants were further categorized into three negative mood groups: depression, anxiety, and stress, with 24 participants in each group. Within each mood group, participants were divided into three subgroups based on the severity of their mood (mild, moderate, and severe), with 8 participants in each subgroup. The experiment spanned 12 weeks, with two 45-min training sessions per week. Intensity was monitored throughout the experiment using the Borg Rating of Perceived Exertion (RPE), and heart rate was measured immediately following each session. The training intensity was maintained at 60-69% of HRmax throughout the 12 weeks.

Results

After 12 weeks of MICT, MICT had a positive effect on mild and severe depressive mood, moderate anxiety, and mild stressful mood in sedentary female college students (p < 0.05), but MICT did not have statistically significant effects on moderate depressive mood, mild and severe anxiety, and moderate and severe stressful mood in sedentary female college students (p > 0.05).

Conclusion

MICT may have a beneficial effect on sedentary female college students, particularly those with lower levels of emotional distress. However, due to the absence of a positive control group, it is difficult to draw definitive conclusions about its specific impact. Future studies should employ more rigorous control designs to better assess the role of MICT in improving both the physical and mental health of sedentary female college students.

Smartphone Addiction, Screen Time, and Physical Activity of Different Academic Majors and Study Levels in University Students

Smartphone addiction is increasing among university students. This study aims to explore the differences in screen time and physical activity among university students with and without smartphone addiction, considering their study majors and levels. One hundred and twenty participants from sixteen faculties were included, divided into three academic majors (health sciences, social sciences and humanities, and science and technology). Data were collected using a screen time behavior questionnaire and a screen time application. Physical activity was measured using the Global Physical Activity Questionnaire (GPAQ). This study demonstrated that the smartphone addiction group had higher screen time on both smartphones (p = 0.02) and other devices (p = 0.04). Students in the social sciences and humanities majors had insufficient physical activity according to WHO recommendations. The results showed no correlation between screen time and physical activity, study time, academic major, or study level (p ≥ 0.05). However, a low correlation was observed between physical activity and study time (r2 = 0.27; p < 0.05), as well as study level (r2 = -0.31; p < 0.05). Our findings show that the total screen time for university students with and without smartphone addiction exceeded 8 h per day. Real-life activities should be promoted to reduce screen time. Encouraging physical activity among senior students and those in social science and humanities majors is crucial for fostering healthy behaviors in the future. Physical education and recreational activities should be emphasized in these groups, along with the development of programs or class activities designed to promote physical activity and reduce screen time.

Sit is not lit: Examining the impact of message framing, modality, and peer influence on attitudes and intentions to reduce sedentary behavior

This study examines the effects of gain-loss framing, messaging modality, peer influence, and individual factors such as social norms and self-efficacy on the attitudes and intentions to reduce sedentary behaviors among university students, specifically through (a) taking breaks and (b) taking 10,000 steps daily. We conducted a two-week health campaign field experiment on Instagram in January 2022, delivering ten posts with tailored messages to 284 university students in Singapore (valid N = 249). The participants were predominantly female (70.16%), ages 21-34 years (M = 24.2, SD = 3.19). This study measured attitudes and intentions to take breaks and 10,000 steps daily as key outcomes. The study yielded three key findings: (1) Gain-loss framing effects were amplified by peer influence, descriptive norms, and injunctive norms, with peer influence amplifying loss framing and both norms amplifying gain framing; (2) Gain framing was more effective than loss framing for motivating the intention to take 10,000 steps; (3) Injunctive norms were associated with attitudes and intentions to take breaks and the intention to take 10,000 steps, while self-efficacy was associated with attitudes toward taking breaks and both attitudes and intentions to take 10,000 steps. This study contributes theoretically by demonstrating how social dynamics amplify framing effects, with peer influence enhancing loss framing on attitude towards taking breaks and norms strengthening gain framing on attitude and intention towards taking 10,000 steps. Practically, it suggests health campaigns can effectively promote behaviors like taking breaks or walking by leveraging norms, peer influence, and self-efficacy.

Behavioural patterns of university students during the COVID-19 pandemic: A cross-sectional study of the effects of active transportation, uninterrupted sitting time, and screen use on physical activity and sitting time

Background

The closure of universities due to the coronavirus disease 2019 (COVID-19) pandemic significantly affected students' behaviours, particularly regarding physical activity, sitting time, and screen use. This study aimed to determine the effect of active transportation duration, uninterrupted sitting time, and screen time to study on physical activity and sitting time during the confinement.

Methods

This was a cross-sectional study based on data collected via an online questionnaire for university students during the second confinement in France (between October and December 2020). The questionnaire assessed physical activity and sedentary behaviour, and contained questions about modes of transport, and perception of uninterrupted sitting time and screen time to study prior to confinement and during confinement. Participants (N=2873) completed the International Physical Activity Questionnaire (IPAQ) in an average time of around 15 minutes, after providing digital informed consent. Multiple regression models assessed how time duration of active transportation, uninterrupted sitting time, and screen time studying increased or reduced confinement effects on physical activity and sitting time.

Results

The regression models showed that physical activity decreased during confinement for students who engaged in more prolonged periods of active transportation prior to confinement. Moreover, the perception of long, uninterrupted sitting time and high screen time prior to confinement significantly increased sitting time during confinement. Students who adopted the most active transport time prior to confinement were the least likely to increase their screen time during confinement.

Conclusions

Confinement reduced physical activity levels and increased sitting time, mainly among students who adopted active transport and accumulated longer uninterrupted sitting time prior to confinement. Students who combined-long periods of uninterrupted sitting time with high screen use could be a riskier profile for health. Analysis of physical activity time and sitting position should include its accumulation patterns.

Food consumption associated with depression, anxiety and stress in students entering a public university

Cross-sectional study investigated the association of fresh or minimally processed foods and ultra-processed food consumption with symptoms of depression, anxiety and stress in students from a Brazilian public university. Undergraduate students admitted in 2022 answered an online questionnaire during their first semester. Consumption of 12 subgroups of fresh or minimally processed foods and 13 of ultra-processed foods on the previous day were investigated (affirmative answer for ≥ 5 subgroups was classified as high consumption). Depression, anxiety and stress were investigated using the DASS-21 and mild to extremely severe symptoms were grouped to be compared with individuals without symptoms. Adjusted logistic regression models estimated the Odds Ratio (OR) of the association between symptoms of depression, anxiety and stress (outcomes) and food consumption (exposures), with a significance level of 5%. A total of 924 students were evaluated, of whom 57.7% presented symptoms of depression, 51.9% of anxiety and 59.4% of stress. A high consumption of fresh or minimally processed foods was observed in 80.3% of the students, with a higher frequency among those without symptoms of depression, anxiety, and stress, while 38.9% showed a high consumption of ultra-processed foods, without differences according to symptoms. High consumption of fresh or minimally processed foods was associated with a lower likelihood of symptoms of depression (OR: 0.62; p=0.011), anxiety (OR: 0.58; p=0.003) and stress (OR: 0.69; p=0.043). No association was found between ultra-processed and mental health outcomes. Actions that support and encourage the consumption of healthy food in the university environment can contribute to mental health outcomes.

Effect of early follicular phase of menstrual cycle on hip flexion-extension isokinetic parameters in sedentary female students

Researchers conducted this observational study on sixty young females to detect the effect of the early follicular phase of the menstrual cycle on hip muscle performance. The Biodex Isokinetic dynamometer 4 pro was used. The authors used a dependent t-test and detected a statistically significant increase in the mean values of all hip flexion and extension isokinetic parameters at angular velocities 90°/sec and 180°/sec (p < 0.05) post-menstruation in comparison to the early follicular phase. The AGON/ANTAG ratio and hip ROM had a statistically significant reduction at the angular velocity 90°/sec (p = 0.003, p = 0.041 respectively) post-menstruation in comparison to the early follicular phase, while they showed no statistically significant change at the angular velocity 180°/sec (p = 0.070, p = 0.236 respectively). The authors through these results try to direct physiotherapists and physical education instructors to schedule training and activities for sedentary females according to their menstrual cycles to avoid any risk of injury.

Physical activities, sedentary behavior, sleep quality, and quality of life among female medical versus nonmedical college students: A cross-sectional study

Despite the numerous health benefits of physical activity (PA), sedentary behavior (SB) and physical inactivity remain major public health concerns. A lack of PA increases the chance of developing some noncommunicable diseases that are on the rise worldwide. Therefore, this study aimed to evaluate the level of PA, SB, sleep quality (SQ), and quality of life (QOL) among Saudi female college students. A cross-sectional study was carried out among female students enrolled in various colleges, both medical and nonmedical, at King Saud University in Riyadh during the academic year 2018 to 2019. Participation posters were sent to colleges' departments, and survey links were shared through university social media channels. The study utilized the International Physical Activity Questionnaire and the Pittsburgh Sleep Quality Index to evaluate PA and SQ and the World Health Organization Quality of Life Assessment Instrument to evaluate QOL. In order to conduct statistical analyses, frequency counts, means, and standard deviations were calculated for PA, SQ, and QOL scores. In this study, 131 Saudi female college students were conveniently recruited from 223 who met the inclusion criteria, with a mean age of 20.4 ± 1.4. Most participants were from medical colleges (n = 86, 6, 5.6%) and the minority were nonmedical (n = 45, 34.4%). We have found that International Physical Activity Questionnaire indicated that most students had low PA (52% of the participants), about 35% had a moderate PA, and only 17% had high PA. SB was present among 22.9% of participants. Nearly 68.7% of the students scored poorly on the Pittsburgh Sleep Quality Index for SQ. The students had high QOL, with a mean WHOQOL-BREF total score of 90.76 ± 12.77. Medical and nonmedical students showed no significant differences in PA, SB, or QOL. No apparent relationship was found between PA and SQ or QOL. This study shows that a significant proportion of female college students maintain an unfavorable lifestyle characterized by insufficient PA and subpar SQ. Implementing programs that encourage students to be more physically active, reduce sedentary time, and integrate sleep education programs to improve their sleep habits are necessary.

University Coaching for Activity and Nutrition (UCAN): A weight-inclusive health coaching program

Background: Given the body image and disordered eating struggles prevalent in young adults, weight-inclusive anti-diet programs are needed on college campuses. Such programs replace weight loss advice with changes that center physical and mental well-being. Methods/Program Design: University health and wellness programs such as University Coaching for Activity and Nutrition (UCAN) is a novel weight-inclusive health and wellness coaching program designed to support university students and faculty/staff in their development and maintenance of self-care behaviors related to physical activity, nutrition, sleep, and stress management. Specifically, we describe the program's mechanisms for participant recruitment, health coach training, session protocol, program evaluation, and supervision so other campuses can replicate the program model at their respective universities. Discussion: This work can help campuses cultivate positive self-care habits that improve physical and mental health through the lens of a weight-inclusive paradigm while also creating research and service-learning experiences for pre-health professionals.

Characterising the activity, lifestyle behaviours and health outcomes of UK university students: an observational cohort study with a focus on gender and ethnicity

BACKGROUND

Health-related outcomes and behaviours in university students are known to be poor relative to the general population. The substantial contextual shifts related to the COVID-19 pandemic, combined with increased numbers of students from minoritised ethnicity backgrounds and presenting as trans and gender diverse (TGD), means that up-to-date information is unavailable. The primary aim of this study was therefore to characterise the current movement, dietary and lifestyle behaviours, mental health, and Body Mass Index (BMI) of UK university students and assess differences between genders and ethnic groups.

METHODS

An online, self-report survey was administered across three years (2021-2023). Three independent cohorts of university students' (n = 6,327) completed the survey on four key topic areas. One-way ANOVAs were used to assess differences between genders (men, women, TGD), and independent samples t-tests were used to assess differences between ethnic groups (White, Minoritised Ethnicity).

RESULTS

30% of students were not meeting physical activity guidelines, 54% were sedentary for ≥ 6 h·d- 1, 83% had poor diet quality, 51% were in high or increased risk groups for alcohol consumption, 18% experienced terrible or poor sleep quality, and 32% were overweight or obese. Gender differences were present for all variables other than walking physical activity (WPA) (P < 0.05), with men having better mental health and engaging in healthier movement and sleeping behaviours, whereas women had more healthful dietary and drinking behaviours, and TGD students had poorer outcomes compared to cis-gender students in most domains. Differences between White and minoritised ethnicity students were present for all variables other than sedentary behaviour, diet quality, WPA and BMI (P < 0.05); students of minoritised ethnicity engaged in better movement, drinking and sleep behaviours in addition to having more positive mental health than White students.

CONCLUSION

The findings of the current study provide an update on the landscape of UK university students' health and health-related behaviours. Overall, health-related outcomes and behaviours are poor in this population and these data suggest that gender and ethnicity play a role in determining students' health and health-related behaviours. Therefore, these factors should be considered when developing strategies to promote healthy living in the context of higher education.

Knowledge, attitudes and behavior of Gulf medical students in relation to Food Dome dietary guidelines: a mixed-method research

This mixed-methods research is the first to explore knowledge, attitudes and behaviours in relation to the Food Dome dietary guidelines (FDDG) among Gulf medical students. Quantitative phase included the administration of Food Dome questionnaire among n = 414 students; qualitative phase used focus group discussions. The quantitative findings show that more than half the sample reported that they had heard of the FDDG (55.3%), of which 15.7% followed and 39.6% did not follow the FDDG. An average female knew more about and behaved more in line with the guidelines, Bahrainis and Saudis were more aware than Kuwaitis on average, and those aged 21 or more showed, on average, more behaviour consistency with the FDDG. The qualitative findings show that the food choices of the Gulf medical students largely depend on time, university load, availability, and taste. Suggested recommendations include educational campaigns, FDDG application examples, teaching children from an early age.

Intermittent standing does not acutely improve postprandial metabolism in university students

Height-adjustable workstations offer a practical strategy to reduce sedentary behaviour in student populations, but the effect of standing intervals on young adults' metabolic health remains uncertain. This study investigated the acute impact of breaking up sitting time with intermittent standing on postprandial metabolic responses in university students. Using a randomised, cross-over design, 23 participants (13 females, 10 males; age, 24 ± 5 years; BMI, 23.2 ± 3.1 kg/m2) completed two trials: 2 hours of uninterrupted sitting (SIT); and 2 hours alternating between sitting and standing every 30 minutes (STAND). During this period, participants underwent an oral glucose tolerance test, with [glucose] and [insulin] measured. Ad libitum food intake post intervention was also measured. No significant effects between trials nor trial × time interaction was found for [glucose] or [insulin] (all p > 0.05). The postprandial iAUC did not differ for [glucose] (p = 0.824; SIT: 222 ± 83 mmol/L; STAND: 225 ± 90 mmol/L) or [insulin] (p = 0.269; SIT: 17507 ± 9738 pmol/L; STAND: 15649 ± 10181 pmol/L). There were no differences in energy or macronutrient intake between trials. These findings indicate that interrupting sitting with 30-minute standing intervals does not improve postprandial metabolic responses in young, normal-weight adults.

Patterns and correlates of sedentary behavior among university students

Objective: To characterize the context, patterns, and correlates of sedentary behavior (SB) in university students. Participants: A total of 95 adults (41% men) enrolled in 34 different undergraduate majors. Methods: SB was assessed by questionnaire and accelerometer. Results: Objective SB and moderate-to-vigorous physical activity (MVPA) accounted for 8.4 ± 1.5 and 1.2 ± 0.5 h·day-1, respectively. Most SB was spent in occupational, leisure, and screen time behaviors, and was accumulated in short bouts of 10 min or longer. Women were more sedentary than men (522.0 ± 80.3 vs. 486.1 ± 91.3 min·day-1, p = 0.03) and engaged in more prolonged bouts of SB. Correlates of SB included female sex, smoking, light activity, MVPA, and markers of obesity, with higher levels of light activity and current smoking the strongest and most consistent correlates of reduced SB. Conclusions: University students engage in high amounts of SB and accumulate most of their SB in short bouts, with differences in patterns of SB between men and women.

Food Consumption Patterns and Sedentary Behaviors Among the University Students: A Cross-Sectional Study

Background

University is a critical period regarding unhealthy changes in eating behaviors in students. University students often face significant changes in their eating habits and physical activity levels, which can impact their overall health.

Aims

To investigate the eating habits and sedentary behavior of university students in Dhaka.

Methods

This research was based on a cross-sectional study. The snowball sampling technique was applied to survey university students in Dhaka city. Structured questionnaires were used for data collection through an online survey. Data collection was done from November 2022 to April 2023. Descriptive statistics, including frequency, percentage, mean, and standard deviation (SD), were computed for the variables of interest. Chi-squared test was performed to estimate the association between the participants' eating habits, sedentary behaviors, and BMI and eating habits. In all analyses, a p-value of < 0.05 was considered statistically significant.

Results

A total of 444 students participated in this study; 44% of them consumed breakfast irregularly. Only 25% of students favored vegetables. About 55% of students preferred junk food. Furthermore, only 19% of students consumed fruits daily. This study also found that a substantial proportion of students used the internet and mobile phones for long periods and didn't practice physical activity. According to the Chi-squared test, dinner habits (p < 0.001), smoking status (p < 0.001), alcohol consumption (p = 0.014), watching television (p = 0.023), and practicing physical activity (p = 0.023) had a significant association with eating habits and sedentary behaviors amongst the participants.

Conclusions

Overall, most participants in this study exhibited commendable dietary patterns, except for meal frequency, fruit intake, consumption of junk food, and fried food. However, their physical activity levels were notably inadequate, largely characterized by a sedentary lifestyle involving substantial internet and mobile phone usage.

Encouraging movement opportunities through theory-informed video education among undergraduate students: the MOVE study

Objective: To explore the impact of a theory-informed educational video on undergraduates': motivational readiness, self-efficacy, and decisional balance about changing sedentary time; sedentary time; and perceptions of sedentarism over time and compared to a control. Participants: Undergraduates (N = 160) from a Canadian institution. Methods: A single-blind randomized controlled trial using an intervention (sedentary video) and control (sleep video) group. Participants completed two validated questionnaires at baseline, immediate post-intervention, and one-month follow-up plus open-ended questions. Linear mixed models and content analysis were used. Results: No significant differences were observed between groups. Increases in self-efficacy (p = .016; d = 0.27) and decisional balance (p = .008; d = 0.31) were observed within intervention participants from baseline to post-intervention, and decreases in sedentary time at post-intervention (p = .032; d = -0.40) and follow-up (p = .006; d = -0.46). Conclusions: This theory-informed sedentary time video shows promise regarding undergraduates' sedentarism.

Unhealthy Lifestyle Contributes to Negative Mental Health and Poor Quality of Life in Young University Students

Background: A negative lifestyle is reported to be related to poor mental health and quality of life (QOL). However, there is little information on this in university students. The objective of the present study was to investigate the association between mental health (i.e., anxiety, depression symptoms and stress), QOL, SWLS and lifestyle parameters (i.e., PA, sleep duration, ST and food habits) among Chilean university students and then to determine the differences in mental health, QOL, SWLS and lifestyle parameters according to gender. Methods: This cross-sectional study included a total of 211 university students (128 females and 83 males) aged 18-28 years. Mental health, QOL and lifestyle were measured through validated questionnaires. Results: Bad food habits (lowest score in the food survey) were linked to anxiety (2.3 [0.22-4.36], p = 0.03), depressive symptoms (3.75 [1.54-5.9], p = 0.001) and stress (2.24 [0.31-4.17], p = 0.023). Furthermore, <6 h of sleep was related to poorer mental health (13.5 [7.6-19.5], p = 0.001), anxiety (4.2 [2.0-6.4], p < 0.001), depressive symptoms (5.5 [3.2-7.9], p < 0.001) and stress (3.8 [1.8-5.9], p < 0.001). In addition, ≥4 h of ST was linked positively to negative mental health (8.3 [2.86-13.7], p = 0.003), depressive symptoms (3.45 [1.47-5.4], p = 0.001) and anxiety (3.2 [1.05-5.4], p = 0.004). Non-physical activity was related to the scores for anxiety (2.6 [0.20-5.0], p = 0.030), depression (2.7 [0.009-5.3], p = 0.049) and stress (2.4 [0.12-4.7], p = 0.039). Conclusions: this study showed that unhealthy lifestyle factors (i.e., insufficient sleep, lack of PA and prolonged ST) were strongly associated with poorer mental health and QOL in university students. These findings highlight the importance of addressing these aspects of lifestyle in intervention and health promotion programs aimed at young university students in order to improve their mental health and overall QOL.

Mood states of active and insufficiently active adolescents related to sleep quality, gender, academic performance and guidelines for the post-COVID-19 scenario

Objective

To evaluate the impact of physical activity on the mood states of active and insufficiently active Italian adolescents and the relationships with sleep quality, sex, and academic performance, analyzing guidelines for the post-COVID-19 scenario.

Methods

This is a cross-sectional, quantitative, and descriptive study. Data collection was carried out through an electronic questionnaire via Google Forms. Adolescent students from schools in the Lazio region, Italy, were evaluated.

Results

In total, 437 Italian adolescents were included, with a mean age of 15.9 ± 1.37 years. The average time of exercise reported by the students was 277 min per week. Physical activity appears to be positively correlated with improved mood states, particularly in adolescents who engage in 150 min or more of physical activity per week, who exhibited notably higher levels of vigor. It was found that female adolescents presented a worse mood state, greater tension, depression, anger, fatigue, and mental confusion, and worse vigor when compared to boys and that adolescents who had poor sleep quality presented significantly worse mood state. Adolescents with an insufficient perception of academic performance demonstrated a significantly worse mood state, tension, depression, anger, and mental confusion, with a submerged mood profile when compared to adolescents who perceived themselves as excellent, with an iceberg profile. In the regression analysis, it was found that for each minute of physical activity practiced, the score in the state of vigor of the adolescents increased by 0.02 and mental confusion decreased by 0.002.

Conclusion

From the present findings, we conclude that recommendations on PA practices for adolescents should be strengthened, as a way to mitigate possible damage to mood states, especially in the post-COVID-19 scenario. Future studies need to deepen the relationships between the mental health, sex, and academic performance of adolescents to strengthen positive mood states and elucidate information on the type, intensity, and dosage of physical activity to achieve mood benefits.

Effects of short video addiction on college students' physical activity: the chain mediating role of self-efficacy and procrastination

Introduction

Excessive use of short video applications can adversely affect the physical and mental health of college students. At present, regarding the effect of short video addiction on physical exercise, few scholars have studied the mechanism of action. This study aims to investigate the mechanism by which short video addiction impacts college students' physical exercise. Therefore, we investigated the correlation between short video addiction and physical activity, and examined the influence of self-efficacy and procrastination on this relationship.

Methods

In this research, 304 college students were selected as survey subjects. The questionnaires included Short Video Addiction Scale, Physical Activity Rating Scale, General Self-Efficacy Scale, and Short Version General Procrastination Scale. The data underwent correlation analysis using SPSS and mediation effect analysis using the PROCESS macro program.

Results

(1) 61.51% (187) of college students' physical activity was low exercise. (2) Physical activity was significantly negatively impacted by short video addiction. (3) Self-efficacy played an independent mediating role in the association between short video addiction and physical activity. (4) The association between short video addiction and physical activity was independently mediated by procrastination. (5) Self-efficacy and procrastination function as chain mediators in the association between short video addiction and physical activity.

Discussion

Our research identifies the role that self-efficacy and procrastination play in the connection between short video addiction and physical activity. Decreasing the utilization of short video applications and enhancing self-efficacy can reduce procrastination and improve physical activity for college student groups.

Real-Time Vibration Feedback from a Smartphone Application Reduces Sedentary Time but Does Not Increase Physical Activity Among Medical Students

Background: Sedentary behavior is associated with various adverse health outcomes. Medical students often experience high academic demands, leading to increased sedentary time. This study aimed to evaluate the effectiveness of a mobile app providing real-time feedback in reducing total sedentary time and prolonged sedentary bouts and in promoting physical activity among medical students. Methods: Seventy-seven medical students from Jazan University (mean age: 21.4 years; range: 20-25 years) participated in this study. Participants were assigned to either the control group (n = 40) or the intervention group (n = 37). The intervention group received real-time vibration feedback via a mobile app, prompting movement every 30 min of sedentary time, while the control group received no intervention. Sedentary behavior and physical activity levels were assessed using the Activities Completed Over Time in 24 h. Paired t-tests were conducted to examine within-group changes, and a two-way ANOVA was used to assess the interaction effect of time and group on sedentary time and physical activity. Results: After six weeks, the intervention group showed significant within-group reductions in their total sedentary time of 1.82 h (p = 0.01) and prolonged sedentary bouts of 1.91 h (p = 0.001), while the control group had no significant changes. Physical activity levels did not significantly change within either group. The two-way ANOVA revealed that there was no significant change over time between the two groups in their total sedentary time F (1, 75) = 1.590, p = 0.21, prolonged sedentary bouts F (1, 75) = 3.499, p = 0.06, or physical activity F (1, 75) = 0.565, p = 0.45. Conclusions: Real-time feedback from mobile apps resulted in significant within-group reductions in total and prolonged sedentary time among medical students in the intervention group. Low-cost mobile apps providing real-time feedback may be an effective intervention for reducing sedentary behavior among medical students, potentially improving their health and well-being.

30 Years of Change: Declining Motor Fitness and Anthropometric Shifts in Polish University Students (1994-2024)

BACKGROUND

To assess changes in the anthropometric and motor characteristics of male and female Polish university students between 1994 and 2024.

METHODS

The first study was conducted in 1994 on 712 female and 495 male university students aged 19-25 years (19.94 ± 1.09), and the second study was conducted in 2024 on 323 female and 339 male university students aged 19-25 years (19.92 ± 1.08). The participants' body mass and height were measured, and the students participated in a modified version of Pilicz's test consisting of four motor ability tests. The changes in the students' performance over time were also analyzed in the context of their socioeconomic status (SES), including the place of permanent residence and the parents' education.

RESULTS

The students' BMI values (as well as body mass and body height in female students) were significantly higher (p < 0.001) in 2024 than in 1994. The male students examined in 1994 demonstrated significantly higher strength abilities in the medicine ball forward throw test. In turn, the females studied in 1994 received significantly better scores in motor ability tests, including the zig-zag run, 1-Minute Burpee Test, and the medicine ball forward throw (29.4 s, 22 cycles, 591.3 cm, respectively) than those examined in 2024 (30.1 s, 19.3 cycles, and 463.3 cm, respectively). The variations in the results were similar when the participants' SES was considered in the analysis, which suggests that these factors had no significant effect on the analyzed characteristics over time.

CONCLUSIONS

This study revealed a greater decline in the anthropometric and motor characteristics of female than male university students over a period of 30 years. The observed changes were not influenced by SES factors such as the place of permanent residence or the parents' education.

Physical activity, weight management, and mental health during COVID-19 lockdown: A cross-sectional study of healthcare students in China

BACKGROUND

There is growing evidence that the social blockade brought about by the COVID-19 pandemic has dramatically affected college students' physical activity; however, their weight management behaviors and mental health have not been fully explored, especially among healthcare students. This study aimed to assess physical activity, weight management behaviors, and mental health among healthcare students during the campus lockdown and to analyze the factors influencing physical activity.

METHODS

A cross-sectional survey of 1,216 healthcare students from March 24, 2022, to April 11, 2022. To collect information about students' physical activity, weight management behaviors, and mental health, they were asked to complete the Physical Activity Questionnaire-Short Form (IPAQ-SF), 11 issues related to weight management behavior, and the World Health Organization 5-Item Well-Being Index (WHO-5) questionnaire. Binary logistic regression was performed to determine the factors influencing physical activity.

RESULTS

Almost half of the participants had low levels of physical activity (45%), the mean score for weight management behavior was 39.55±6.26, and 54.6% had low levels of well-being. Healthcare students without exercise habits during the non-epidemic period reported lower levels of physical activity (OR = 1.81; 95%CI = 1.41-2.34, P<0.001). Participants with poor weight management behavior were more likely than other participants to report lower levels of physical activity (OR = 0.92; 95%CI = 0.90-0.94, P < 0.001). Likewise, the odds of being physically inactive were higher among the happier participants (OR = 0.98; 95%CI = 0.96-0.99, P = 0.031).

CONCLUSIONS

During the COVID-19 lockdown, most healthcare students in Gansu province lack physical exercise and have a low health level. Significant correlation factors for low physical activity levels were grade level, non-lockout exercise habits, weight management level, and well-being. These findings demonstrate the importance of developing targeted policies and programs encouraging physical activity among medical students.

Gender Differences in the Relationship between Physical Activity, Postural Characteristics and Non-Specific Low Back Pain in Young Adults

Background/Aim: University students are a particularly vulnerable population, as they spend increasing amounts of time sitting, which poses a major threat to their musculoskeletal health and posture. The aim of this cross-sectional study was to investigate gender differences in the relationships between physical activity (PA) and sedentary behavior, spinal curvatures and mobility, the endurance and balance of the trunk muscles, and the possible presence of non-specific low back pain (NS-LBP) in young adults aged 18-25 years. Methods: A total of 139 students completed all required tests. Results: Male students engaged in significantly more PA related to recreation, sports and leisure and were significantly more likely to be hyperkyphotic than female students. The more the male students participated in sports, the more pronounced the thoracic kyphosis. Female students had significantly more pronounced lumbar lordosis and anterior pelvic tilt that correlated with lumbar lordosis. Female students generally had significantly higher trunk extensor endurance and more balanced trunk musculature than males. NS-LBP correlated with PA in female students who generally had higher levels of NS-LBP than male students, with a statistically significant difference between those who practiced the most PA. Conclusions: Our results suggest that female students practice less PA and have pronounced lordosis and trunk extensor endurance, in contrast to males who practice more PA and have pronounced trunk flexor endurance and hyperkyphosis. Our findings suggest that more PA should be encouraged but implemented with caution and as an individualized gender-specific approach to prevent postural deformities and chronic musculoskeletal disorders, including NS-LBP.

Videoconferencing During the COVID-19 Pandemic is Associated with Sleep Disruption in Young Adults

Purpose

The COVID-19 pandemic resulted in a shift to working and learning from home and a concomitant rise in the use of virtual communication technology, such as videoconferencing. The current study prospectively examined the association between videoconferencing and sleep in a sample of young adults attending a university during the pandemic. The effects of videoconferencing on health and wellness outcomes and academic performance were also evaluated.

Patients and Methods

Participants completed the core Consensus Sleep Diary and reported engagement in videoconferencing, the use of electronic devices, and physical activity daily for 8 consecutive days. They also completed baseline measures of sleep, communication technology use, physical activity, and mental distress, as well as released their end-of-term GPA. Results were evaluated via multilevel modeling and path analysis.

Results

Participants with a heavier videocall volume lost 17 m of sleep and suffered nearly a 1% reduction in sleep efficiency for each additional hour of videoconferencing compared to those with a lower call volume. They also tended to spend more time awake during the night, have earlier sleep midpoints, and report worse sleep, although those trends did not reach statistical significance. For everyone, including individuals with lower videocall volume, earlier sleep midpoints, lower sleep quality, somewhat shorter sleep, and higher fatigue were reported on days with a relatively high videocall load compared to days with a low videocall load. Increased academic engagement with videoconferencing predicted lower academic performance and higher psychological distress: Both relationships were mediated by sleep. Use of videoconferencing for personal reasons, however, was directly associated with a reduction in distress.

Conclusion

Videoconferencing is an important determinant of sleep and may impact health and wellness as well as academic outcomes in young adults. The effects of virtual communication on sleep and human behavior warrant further study in this and other populations.

Sedentary behaviour in Australian university students: The contribution of study-related sedentary behaviour to total sedentary behaviour

ISSUE ADDRESSED

Seated activities are attributed to increased sedentary behaviour (SB) and adverse health effects, but little is currently known about university students' SB, particularly study-related SB. This study describes the sociodemographic variations of domain-specific SB in regional Australian university students and the contribution of study-related SB to total SB.

METHODS

Self-reported daily SBs from a cross-sectional survey of 451 students were used. Domain-specific and total SB were described within sub-groups, and differences examined using independent t-tests. Multinomial regression was used to examine the association of tertiles of duration in study-related SB with total and other domain-specific SBs.

RESULTS

Study participants were a median age of 21 (19-25 years), mostly female (76%) and represented different years of study. On average, students spent 882 ± 292 min/day in total SB, with most SB occurring in the study, screen time and 'other activity' domains. No sociodemographic variations were found in total SB, but significantly higher study-related SB were reported by students studying full time (p < .001) and who moved from their family home to study (p < .022). Study-related SB contributed 36% of total SB, with students most sedentary during study having the highest total SB.

CONCLUSIONS

This study suggests university students have high levels of SB, primarily in the domains of study, screen time and other activities. SB reduction strategies in universities and targeting screen time, across various sociodemographic groups (e.g., gender, university enrolment status, and living arrangements), may be important in reducing SB in university students. SO WHAT?: University students are highly sedentary and should be included in SB programs especially students studying full time and those who moved from their family home in the study domain.

Isotemporal substitution analysis of time between sedentary behavior, and physical activity on sleep quality in younger adults: a multicenter study

OBJECTIVE

To evaluate the effects of replacing time spent in sedentary behavior (SB) with moderate to vigorous physical activity on sleep quality in young adults.

METHODS

Multicenter cross-sectional study, carried out with students enrolled in undergraduate courses at universities in Brazil. Sleep quality was assessed using a question of the World Health Organization Quality of Life (WHOQOL-brief) and classified as good or poor sleep quality. SB was evaluated by self-reported total sitting time, and the level of leisure-time PA was classified according to the intensity of moderate-intensity physical activity (MPA) and vigorous-intensity physical activity (VPA), which were assessed using a self-reported questionnaire. An isotemporal replacement logistic model was used to evaluate the effects of different SB, MPA, and VPA sessions on sleep quality.

RESULTS

A total of 8,059 study participants were evaluated, the majority had poor sleep quality (64.79%), were physically inactive (48.28%, defined as practicing < 150 min of MPA or < 75 min of VPA per week), and spent ≥ 9 h/day in SB (55.08%). The multivariate model showed an association between non-adherence to wake-based movement guidelines and poor sleep quality, where those with one altered behavior were 43% more likely to have poor sleep quality (OR:1.43;95%CI:1.27 to 1.60), while individuals with two altered behaviors were 97% more likely (OR:1.97;95%CI:1.73 to 2.24). In the isotemporal analysis, replacing MPA and VPA with equivalent time in SB increased the odds of poor sleep at all times assessed, with peaks of 56% for MPA and 68% for VPA.

CONCLUSION

The results of the present study indicate that replacing SB with the same amount of MPA or VPA may reduce poor sleep quality.

Effects of light-intensity physical activity on cardiometabolic parameters in young adults with overweight and obesity: The SED-ACT randomized controlled crossover trial

AIMS

To investigate how a change in body position with light-intensity physical activity (PA) 'snacks' (LIPAS, alternate sitting and standing, walking or standing continuously) compared with uninterrupted prolonged sitting affects glucose metabolism and heart rate variability (HRV) parameters in young adults with overweight and obesity.

MATERIALS AND METHODS

We conducted a four-arm randomized controlled crossover trial. The following conditions were tested during an 8-h simulated workday: uninterrupted prolonged sitting (SIT), alternate sitting and standing (SIT-STAND; 2.5 h total), continuous standing (STAND), and continuous walking (1.0 mph; WALK). The primary outcome was to investigate how a change in body position (alternate sitting and standing, walking or standing continuously) compared with uninterrupted sitting affects mean 8-h glucose metabolism. Secondary outcomes included the effects on 2-h postprandial glucose concentrations, as well as on 8-h/24-h heart rate and HRV parameters, in the respective study arms. Capillary blood samples were drawn from an hyperemised earlobe in the fasted state and once every hour during each trial intervention by puncturing the earlobe with a lancet and collecting 20 μL of blood (Biosen S-Line Lab+; EKF diagnostics, Barleben, Germany). HRV was assessed for 24 h including the 8-h intervention phase, and a home phase by means of a Holter electrocardiogram. All participants received the same standardized non-relativised breakfast and lunch during the four trial visits.

RESULTS

Seventeen individuals (eight women, mean age 23.4 ± 3.3 years, body mass index 29.7 ± 3.8 kg/m2, glycated haemoglobin level 34.8 ± 3.1 mmol/mol [5.4 ± 0.3%], body fat 31.8 ± 8.2%) completed all four trial arms. Compared with SIT (89.4 ± 6.8 mg/dL), 8-h mean glucose was lower in all other conditions (p < 0.05) and this was statistically significant compared with WALK (86.3 ± 5.2 mg/dL; p = 0.034). Two-hour postprandial glucose after breakfast was approximately 7% lower for WALK compared with SIT (p = 0.002). Furthermore, significant time × condition effects on HRV parameters favouring light-intensity walking were observed (p < 0.001).

CONCLUSIONS

Replacement and interruption of prolonged sitting with light-intensity walking showed a significant blood glucose-lowering effect and improved HRV during an 8-h work environment in young adults with overweight and obesity.

The effects of prolonged sitting behavior on resting-state brain functional connectivity in college students post-COVID-19 rehabilitation: A study based on fNIRS technology

Functional near-infrared spectroscopy (fNIRS) was used to explore the effects of sedentary behavior on the brain functional connectivity characteristics of college students in the resting state after recovering from Corona Virus Disease 2019 (COVID-19). Twenty-two college students with sedentary behavior and 22 college students with sedentary behavior and maintenance of exercise habits were included in the analysis; moreover, 8 ​min fNIRS resting-state data were collected. Based on the concentrations of oxyhemoglobin (HbO2) and deoxyhemoglobin (HbR) in the time series, the resting-state functional connection strength of the two groups of subjects, including the prefrontal cortex (PFC) and the lower limb supplementary motor area (LS), as well as the functional activity and functional connections of the primary motor cortex (M1) were calculated. The following findings were demonstrated. (1) Functional connection analysis based on HbO2 demonstrated that in the comparison of the mean functional connection strength of homologous regions of interest (ROIs) between the sedentary group and the exercise group, there was no significant difference in the mean functional strength of the ROIs between the two groups ( p > 0.05 ). In the comparison of the mean functional connection strengths of the two groups of heterologous ROIs, the functional connection strengths of the right PFC and the right LS ( p = 0.009 7 ), the left LS ( p = 0.012 7 ), and the right M1 ( p = 0.030 5 ) in the sedentary group were significantly greater. The functional connection strength between the left PFC and the right LS ( p = 0.031 2 ) and the left LS ( p = 0.037 0 ) was significantly greater. Additionally, the functional connection strength between the right LS and the right M1 ( p = 0.037 0 ) and the left LS ( p = 0.043 8 ) was significantly greater. (2) Functional connection analysis based on HbR demonstrated that there was no significant difference in functional connection strength between the sedentary group and the exercise group ( p > 0.05 ) or between the sedentary group and the exercise group ( p > 0.05 ). Similarly, there was no significant difference in the mean functional connection strength of the homologous and heterologous ROIs of the two groups. Additionally, there was no significant difference in the mean ROIs functional strength between the two groups ( p > 0.05 ). Experimental results and graphical analysis based on functional connectivity indicate that in this experiment, college student participants who exhibited sedentary behaviors showed an increase in fNIRS signals. Increase in fNIRS signals among college students exhibiting sedentary behaviors may be linked to their status post-SARS-CoV-2 infection and the sedentary context, potentially contributing to the strengthened functional connectivity in the resting-state cortical brain network. Conversely, the fNIRS signals decreased for the participants with exercise behaviors, who maintained reasonable exercise routines under the same conditions as their sedentary counterparts. The results may suggest that exercise behaviors have the potential to mitigate and reduce the impacts of sedentary behavior on the resting-state cortical brain network.

Determinants of Engagement in Leisure-Time Physical Activity and Club Sports among University Students: A Large-Scale Study

Various socio-demographic, environmental, and lifestyle-related factors have been reported to be associated with physical activity (PA) habits. However, there exist insufficient data comparing different forms of engagement in PA, sports, and exercise. This study aimed to investigate potential factors associated with the engagement in leisure-time PA (LPA) and club sports (CSs) in a large sample of college/university students. This Austria-wide study followed a cross-sectional design with a final sample of 4508 participants (mean age: 24.9 years; 65.9% female) from 52 Austrian colleges/universities. A standardized survey was used to collect data on demographics, anthropometric characteristics, and a wide range of health-related lifestyle factors, including patterns of PA and underlying motivations for PA engagement as well as details of dietary habits, sleep routines, smoking, and alcohol consumption. Descriptive statistics, chi-squared, logistic regression, and MANCOVA were used for data analysis. Across the entire sample, 85.7% of participants reported regular participation in LPA, including 22.5% who were active members of sports clubs. Of the 36 potential motives listed in the questionnaire, "maintaining physical health", "feeling good", and "refreshing the mind" were the most commonly reported factors motivating students to engage in either LPA or CSs. Ten socio-demographic, dietary, or lifestyle factors were identified as predictors of CSs participation (p < 0.01), whereas only two variables (specifically sleep-related factors) were identified as predictors of LPA participation (p < 0.001). These findings emphasize the importance of considering the type of PA and sport participation and the associated determinants when designing tailored strategies to promote an active lifestyle.

Exploring the Psychological Effects and Physical Exertion of Using Different Movement Interactions in Casual Exergames That Promote Active Microbreaks: Quasi-Experimental Study

BACKGROUND

Prolonged sedentary behavior, such as sitting or reclining, has consistently been identified as a stand-alone risk factor for heightened cardiometabolic risk and overall mortality. Conversely, interrupting sedentary periods by incorporating short, active microbreaks has been shown to mitigate the negative effects of sedentary behavior. Casual exergames, which mix elements of casual gaming with physical activity, are one prospective intervention to reduce sedentary behavior because they require physical exertion. Casual exergames have shown promise in fostering emotional and physical advantages when played in specific circumstances. However, little research exists on how different types of movement interactions impact the psychological effects as well as the physical exertion of playing casual exergames.

OBJECTIVE

The primary aim of this work was to explore the psychological effects and physical exertion of playing casual exergames lasting 2 minutes. More precisely, the investigation focused on comparing upper body and full body movement interactions. In addition, the work examined variations in body positions, considering both standing and seated positions during upper body movement interactions.

METHODS

Two casual exergames were developed and investigated through 2 quasi-experimental studies. In study 1, we investigated how players' perceptions of control, exertion, and immersion were affected by using upper body as opposed to full body exergame controllers when playing casual exergames. In study 2, we investigated differences in positive affect, performance, enjoyment, and exertion when playing casual exergames with upper body movement interactions in seated and standing positions.

RESULTS

Study 1 showed that perceived control was significantly higher for upper body movement interactions than for full body movement interactions (P=.04), but there were no significant differences regarding perceived exertion (P=.15) or immersion (P=.66). Study 2 showed that positive affect increased significantly for both standing (P=.003) and seated (P=.001) gameplay. The participants in the standing gameplay group showed slightly higher actual exertion; however, there were no differences between the groups in terms of positive affect, perceived exertion, enjoyment, or performance.

CONCLUSIONS

Casual exergames controlled by upper body movement interactions in seated gameplay can produce similar psychological effects and physical exertion as upper body movement interactions in standing gameplay and full body movement interactions. Therefore, upper body and seated casual exergames should not be overlooked as a suitable microbreak activity.

Effects of Interrupting Prolonged Sitting with Light-Intensity Physical Activity on Inflammatory and Cardiometabolic Risk Markers in Young Adults with Overweight and Obesity: Secondary Outcome Analyses of the SED-ACT Randomized Controlled Crossover Trial

Sedentary behavior (SB) is an essential risk factor for obesity, cardiovascular disease, and type 2 diabetes. Though certain levels of physical activity (PA) may attenuate the detrimental effects of SB, the inflammatory and cardiometabolic responses involved are still not fully understood. The focus of this secondary outcome analysis was to describe how light-intensity PA snacks (LIPASs, alternate sitting and standing, walking or standing continuously) compared with uninterrupted prolonged sitting affect inflammatory and cardiometabolic risk markers. Seventeen young adults with overweight and obesity participated in this study (eight females, 23.4 ± 3.3 years, body mass index (BMI) 29.7 ± 3.8 kg/m2, glycated hemoglobin A1C (HbA1c) 5.4 ± 0.3%, body fat 31.8 ± 8.2%). Participants were randomly assigned to the following conditions which were tested during an 8 h simulated workday: uninterrupted prolonged sitting (SIT), alternate sitting and standing (SIT-STAND, 2.5 h total standing time), continuous standing (STAND), and continuous walking (1.6 km/h; WALK). Each condition also included a standardized non-relativized breakfast and lunch. Venous blood samples were obtained in a fasted state at baseline (T0), 1 h after lunch (T1) and 8 h after baseline (T2). Inflammatory and cardiometabolic risk markers included interleukin-6 (IL-6), c-reactive protein (CRP), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), triglycerides (TGs), visceral fat area (VFA), triglyceride-glucose (TyG) index, two lipid ratio measures, TG/HDL-C and TC/HDL-C, albumin, amylase (pancreatic), total protein, uric acid, and urea. We found significant changes in a broad range of certain inflammatory and cardiometabolic risk markers during the intervention phase for IL-6 (p = 0.014), TG (p = 0.012), TC (p = 0.017), HDL-C (p = 0.020), LDL-C (p = 0.021), albumin (p = 0.003), total protein (p = 0.021), and uric acid (p = 0.040) in favor of light-intensity walking compared with uninterrupted prolonged sitting, alternate sitting and standing, and continuous standing. We found no significant changes in CRP (p = 0.529), creatinine (p = 0.199), TyG (p = 0.331), and the lipid ratios TG/HDL-C (p = 0.793) and TC/HDL-C (p = 0.221) in response to the PA snack. During a simulated 8 h work environment replacement and interruption of prolonged sitting with light-intensity walking, significant positive effects on certain inflammatory and cardiometabolic risk markers were found in young adults with overweight and obesity.

Acceptability, engagement, and preliminary efficacy of a college human physiology course with integrated mindfulness practice to support student wellbeing

Objective

To evaluate the acceptability of and engagement with an undergraduate human physiology course embedded with mindfulness practice. To assess its preliminary efficacy on student mindfulness and wellbeing.

Methods

Students (N = 36, 17% freshman, 33% sophomore, 22% junior, and 28% senior) answered online surveys at course completion. Primary outcomes were course ratings, assignment and assessment completion rates, minutes, types of mindfulness practice, changes in trait mindfulness (Mindful Attention Awareness Scale, MAAS), and self-reported wellbeing outcomes. We ran Chi-square goodness of fit tests and paired Wilcoxon signed-rank tests to decide if the outcomes differed significantly post-class. We tested the dose-response relation between mindfulness practice time and trait mindfulness and whether the out-of-class practice time was consistent across the weeks with generalized linear mixed-effect models.

Results

All participants reported finding the course enjoyable and that they would recommend it to their friends. They practiced for an average of 66 (SD = 27) min per week in the class and 112 (SD = 59) min on their own. The most common out-of-class practices were mindful movements, sitting meditation, and breathing. Per self-reports, the course increased student understanding of specific mindfulness practices and appreciation for their body. It improved wellbeing and trait mindfulness (MAAS mean within-person change = 1.2, SD = 0.8, p < 0.00001). We found no does-response relation between practice time and trait mindfulness.

Conclusions

This pilot study supports that incorporating mindfulness practice into college-level courses may promote student wellbeing and such approaches warrant further investigation.

Unveiling metabolic dysfunction-associated fatty liver disease: Knowledge gaps and attitudes among Lebanese university students

BACKGROUND

Metabolic dysfunction-associated fatty liver disease (MAFLD) is a rapidly growing global health problem. Despite its growing incidence and potential for significant repercussions, MAFLD is still widely misunderstood and underdiagnosed.

AIM

The purpose of this study was to investigate MAFLD-related knowledge, attitudes, and risk profiles among university students aged 17 to 26.

METHODS

A cross-sectional study with 406 university students in Lebanon, equally distributed among males and females, was conducted using a questionnaire that includes demographics, medical information, dietary habits, physical activity, and MAFLD-related knowledge and attitudes.

RESULTS

The findings demonstrated a significant lack of knowledge regarding MAFLD, with more than half of participants (54.7%) having no prior knowledge of the illness. Students exhibited unhealthy lifestyle behaviors such as smoking (68%), insufficient physical exercise (44.1%), and poor food habits (52.5%). Having a family history of heart disease, personal history of diabetes mellitus, a balanced diet and prior knowledge of the disease were associated with a higher knowledge score (p<0.05). A higher attitude score existed among those who have a personal or family history of chronic diseases and those who have a prior negative impression about the disease, prior knowledge of the disease, and those who are physically active (p<0.05).

CONCLUSION

Despite knowledge gaps, university students in Lebanon have, in general, an appropriate and positive attitude towards MAFLD. We recommend the introduction of focused educational interventions to address the necessity of lifestyle changes among university students and the community as a whole. Developing comprehensive MAFLD prevention methods requires future studies in different age groups and demographics.

An internet-based self-help intervention for the reduction of consumption of ultra-processed products and increase of physical activity in Mexican university population: study protocol for a randomized controlled trial

Introduction

The consumption of ultra-processed products has been associated with the etiology of various diseases, mainly metabolic diseases. On the other hand, physical activity acts as a protective factor that helps prevent the appearance of this type of disease. In addition to the physical effects, both the consumption of ultra-processed products (UPPs) and sedentary behaviors have been associated with a significant impact on people's mental health. These problems occur significantly in university students. Online internet interventions are an alternative that has the advantage of reaching a broader sample size and adapting to various problems.

Methods

A randomized controlled clinical superiority trial with two independent groups will be developed with 176 participants. Participants in both groups will be evaluated in 5 steps: (1) pretest, (2) middle of the intervention, (3) post-test, (4) follow-up at 3 months, and (5) follow-up at 6 months. In the experimental group ("UNISALUD"), participants will receive an intervention composed of 11 sessions with interactive elements such as videos, audio, and infographics created through the user experience (UX) principles and based on the health action process approach (HAPA). The participants in the control group will be on the waiting list and will receive treatment 27 days after fulfilling the inclusion criteria. Thus, participants will not receive the treatment immediately.

Discussion

The study is expected to establish the feasibility of a self-help internet-based intervention created based on the user experience methodology and the health action process model, leading to a significant decrease and increase in the consumption of UPPs, ultra-healthy products, and physical activity, respectively.

Conclusion

Internet-based interventions are scarce in Latin America. Due to their potential, this study will provide data about consumption of UPPs, physical activity, and mental health of the Mexican population, which will influence the reduction of health-related complications through prevention strategies or measures.Clinical Trial Registration:ClinicalTrials.gov, NCT05834842.

Sedentary behavior is associated with the mental health of university students during the Covid-19 pandemic, and not practicing physical activity accentuates its adverse effects: cross-sectional study

BACKGROUND

Movement behaviours, such as sedentary behavior (SB) and physical inactivity, have become a public health issue due to their implications for physical and mental health. The literature indicates that the university environment influences the movement behaviors of university students, and the strategies adopted during the pandemic may have favored a decrease in the practice of physical activity and an increase in the time dedicated to SB in this population. We aimed to evaluate the association of SB and moderate to vigorous leisure-time physical activity (MVPA) with presence of symptoms of mental disorders during the COVID-19 pandemic.

METHODS

This is a multicenter survey conducted with undergraduate students from eight Brazilian universities between October 2021 and February 2022 using an online questionnaire. The outcome variable was symptoms of anxiety and depression, assessed by the Depression, Anxiety, and Stress Scale-21. SB was assessed by total sitting time, being that individuals with ≥ 9 h/day were classified with high SB. The practice of MVPA was evaluated based on weekly frequency, duration, and type of exercise. Subsequently, the ratio between the time spent in MVPA (minutes/day) and the time spent in SB (hours/day) was calculated, being considered as cutoff point was the practice of 2.5 min of MVPA for each sedentary hour. To assess the association between the outcome and explanatory variables, multivariable logistic regression was performed.

RESULTS

A total of 8,650 students participated in the study, with an average age of 23.9 years (SD: ± 6.34). In the multivariate analysis, the odds of anxiety symptoms [OR: 1.37 (95% CI: 1.24-1.50)] and depression [OR: 1.61 (95% CI: 1.47-1.77)] were higher in individuals with ≥ 9 h of SB per day. In the analysis of the relationship between MVPA and SB, not engaging in 2.5 min of MVPA per hour of SB increases the odds of anxiety symptoms [OR: 1.44 (95% CI: 1.31-1.58)] and depression [OR: 1.74 (95% CI: 1.59-1.92)].

CONCLUSION

The results suggest that SB is a risk factor associated with symptoms of anxiety and depression and that not engaging in MVPA exacerbates the negative effects of SB.

Associations between levels of physical literacy and adherence to the 24-h movement guidelines among university students: A cross-sectional study

Objectives

Emerging evidence indicates that the composition of movement behaviours within a 24-h period is associated with multiple health benefits across the lifespan. A concept that emphasises an individual's active lifestyle is physical literacy (PL), yet empirical research exploring the potential associations between PL and 24-h movement guidelines remains scarce. This study aimed to evaluate the associations between levels of PL and adherence to the guidelines among Chinese university students.

Study design

A cross-sectional study.

Methods

Seven hundred and ninety-eight university students (390 male, 19.2 ± 1.2 years) completed all the measurements. Levels of PL and participants' adherence to guidelines including physical activity, sedentary behaviour and sleep were self-reported through Perceived Physical Literacy Instrument, International Physical Activity Questionnaire and Pittsburgh Sleep Quality Index, respectively. Two-way ANOVA was conducted to determine the associations between the number of guidelines met (0, 1, 2, or 3) and levels of PL.

Results

The results demonstrate that 36.5% (n = 291) of the participants met all the three guidelines, while 4.1% (n = 33) met none. Further analysis indicated that meeting physical activity or sedentary behaviour guidelines was associated with significantly higher total PL scores, and scores in the sub-domains of Confidence and Physical Competence and Motivation.

Conclusions

The findings provide evidence that young adults who obtained higher PL scores may meet more guidelines during a 24-h period. Future studies should incorporate accelerometer-based physical activity measurements and investigate the causal relationship between PL and adherence to the movement guidelines.

Get active now or later? The association between physical activity and risk and time preferences

Despite the well-established link between physical activity and positive health outcomes, much of the world's population remains inactive. Many people don't invest in health behaviours, such as physical activity, in the present, despite the long-term benefits of this. The aim of this study was to assess the relationship between physical activity levels and risk and time preferences in university students. A maximum likelihood model was used to jointly estimate risk and time preferences (elicited in an incentivised choice experiment), and to examine the relationship between these preferences and self-reported physical activity. Physically inactive people discounted the future significantly more than physically active people did. Physically active people made slightly more risky choices in our risk attitude task, although this directional relationship was not statistically significant. The link between time preferences and physical activity suggests that further research on behavioural strategies such as commitment devices, nudging or temptation bundling may be helpful in increasing physical activity for individuals who discount the future in favour of more immediate benefits.

Factors Associated with the Health-Related Quality of Life of Malaysian Young Adults Post-Pandemic

The transition from school to university brings significant adjustments in lifestyle, body weight, and living environment for young adults, potentially impacting their quality of life. Emerging evidence suggests the coronavirus disease of 2019 (COVID-19) pandemic may have exacerbated these changes. This cross-sectional study involved 361 young adults (18-25 years) from Malaysian tertiary institutions, aiming to identify factors associated with health-related quality of life (HRQOL) post-COVID-19 restrictions. Data were collected online between April and July 2022, utilizing the WHOQOL-BREF for HRQOL assessment. Participants, with a median age of 23, scored highest in the physical health domain (mean: 63.2, SD = 16.2) and lowest in psychological health (mean: 58.2, SD = 16.9). Physical health domain scores varied by ethnicity, the field of study, weight category, and prescription medicine usage; environmental health scores by ethnicity and household income; and social health scores by age. Moderate perceived stress and low perceived support were significant predictors of poor HRQOL. Across the weight categories, sleep quality, perceived stress, and support have consistently impacted the HRQOL domain scores. This study underscores the multifaceted influences on young adults' quality of life during the transition to university, especially in post-pandemic adjustments, highlighting the importance of addressing factors such as perceived stress and support to enhance overall well-being.

Substitutions of physical activity and sedentary behavior with negative emotions and sex difference among college students

BACKGROUND

A growing number of studies have found that physical activity (PA) benefits mental health, and sedentary behavior (SB) increases the risk of psychological symptoms, but it remains unclear whether substituting the duration of different activities may affect the association, and whether sex difference exists among college students.

METHODS

A longitudinal survey was conducted in three colleges in Anhui province, China. A total of 8049 participants validly answered the questionnaire, which included demographic variables, PA, SB and negative emotions (depressive, anxiety, and stress symptoms).

RESULTS

Substituting 30 min per day of SB with equivalent walking was associated with lower scores of depressive symptoms. Stress symptoms were reduced when SB was substituted by moderate intensity PA (MPA) and walking. Substituting 30 min per day of MPA in place of walking and SB was associated with an amelioration of depressive and stress symptoms in females, and a reallocation of 30 min walking was associated with lower depressive and stress symptom scores when SB was replaced in males.

CONCLUSIONS

Replacing SB with walking and MPA ameliorates the depressive and stress symptoms in young adults. The results suggest a reallocation of time from SB or walking to MPA in females while from SB to walking in males may markedly reduce the depressive and stress symptoms in college population.

Sleep duration and quality during the COVID-19 pandemic and the association with physical activity and screen time among Brazilian college students

BACKGROUND

As a result of social isolation during the COVID-19 pandemic, changes in sleep patterns have been observed in many countries, as well as changes in physical activity and screen time. The objective was to investigate sleep duration and quality during the COVID-19 pandemic and its association with physical activity and screen time.

METHODS

Cross-sectional study with students from a University in Rio de Janeiro who answered an online questionnaire between August 2020 and March 2021. Physical activity was assessed using IPAQ-SF. Sleep was investigated based on questions about duration and sleep quality change, and screen time through self-reported questions. Multinomial logistic regression was performed to assess the association between physical activity and screen time with sleep duration and quality. Secondary analyses investigated the influence of the isolation time on this association. The confounding factors used were diagnosis of COVID-19, time of isolation, anxiety, depression, skin color, and gender.

RESULTS

A total of 771 college students with a mean age of 24.5 years (±8.6) answered the questionnaire. About 75% reported more than 8 h of screen time per day and 49.8% were physically inactive. Regarding sleep, 54.9% had worsening sleep, while 40.6% had inadequate sleep duration during the pandemic. Physical activity was associated with improved sleep quality (Odds ratio (OR) 1.72; confidence interval (95% CI) 1.05-2.97). Also, physically active students who spent more than 14 weeks in social isolation demonstrated improved sleep quality (OR 1.99; 95% CI 1.02-3.78) compared to physically inactive individuals. No association was observed for sleep duration. No association was observed between screen time and sleep quality, or sleep duration.

CONCLUSION

During the COVID-19 pandemic, there was considerable worsening of sleep quality, and physical activity was positively associated with improved sleep quality.
