Risk factors of overweight/obesity-related lifestyles in university students: Results from the EHU12/24 study

Prevalence, awareness, attitudes, practices, and associated factors of obesity among adults in Makkah, Saudi Arabia

BACKGROUND

Obesity is becoming increasingly prevalent throughout the world, impairing both life expectancy and quality of life. Despite existing knowledge and awareness about obesity, significant gaps remain in understanding its associated factors and the effectiveness of interventions. This study estimates the prevalence of obesity, identifies its associated factors, and assesses participants' awareness, attitudes, and practices concerning obesity.

METHODS

An analytical cross-sectional study was conducted among 368 adults visiting primary care facilities in Makkah, Saudi Arabia. A structured, pre-validated questionnaire adapted from previous research was used to collect demographic information and assess respondents' awareness, attitude, and practices regarding obesity.

RESULTS

The mean age of the participants was 41.8 ± 2.2 years, and 57.6% were females. Most respondents (97.8%) did not smoke, 32.1% had a family history of obesity, 86.1% consumed an unhealthy diet, and 76.6% did not engage in physical exercise. Approximately 37% of participants were overweight or obese. The study found that 85.9% of participants had a good awareness of obesity, 51.4% demonstrated a favorable attitude, and 33.4% exhibited adequate practices regarding obesity. A considerable proportion of participants (56.3%) recognized obesity based on self-perception. Approximately 38% of participants consumed high-calorie meals when stressed, 24.7% did not get sufficient sleep, and 64.4% did not drink enough water. Most of the participants (91.6%) perceived obesity as a disease, and 60.3% were satisfied with their body shapes. The logistic regression analysis demonstrated that the strongest predictors of obesity were poor awareness of obesity (OR = 10.6, p < 0.001), followed by irregular exercise (OR = 6.3, p < 0.05), and being female (OR = 4.8, p < 0.001). Adequate water intake was found to decrease the likelihood of obesity (OR = 0.1, p < 0.001).

CONCLUSION

Obesity is prevalent among adults in Makkah. Despite a favorable attitude and a good awareness of most aspects relating to obesity, inappropriate practices are common. Additional action and decisions are required to put awareness and attitude into practice.

Effects of nutrition class with cooking lab on college students' eating behaviors and well-being in the United States: a mixed-methods study

BACKGROUND/OBJECTIVES

This study aimed to investigate the effects of college-level nutrition and culinary education on cooking and eating behaviors, as well as psychosocial well-being among students in the United States.

SUBJECTS/METHODS

The study examined changes in cooking attitude, confidence, skills, cooking frequency, and the intake of fruits, vegetables, and whole grains among 73 college students at a university in the southeastern United States over 4 consecutive semesters, from Fall 2018 to Spring 2020. A mixed-methods research design was used to obtain both qualitative and quantitative data. Qualitative data analysis was conducted to explore additional life and psychosocial benefits beyond cooking.

RESULTS

Significant improvements were observed in participants' cooking attitudes, confidence, and skills following the education intervention (P < 0.001). Cooking attitude scores increased from 3.89 to 4.29, while cooking confidence rose from 2.89 to 3.99. Participants also reported higher cooking frequency, along with increased fruit and vegetable consumption (2.68 to 3.77 and 2.74 to 3.8, P < 0.001), though there was no significant change in whole grains intake. Qualitative analysis revealed 4 major themes-teamwork, time management, self-esteem, and financial literacy-highlighting the perceived life and psychological benefits of the course.

CONCLUSION

Integrating cooking labs into college nutrition courses effectively enhances cooking skills, promotes healthful eating behaviors, and contributes to broader psychosocial well-being among students. These improvements were attributed to hands-on lab activities and collaborative learning environments, fostering self-efficacy and life skills.

Patterns of olfactory perception, eating behavior and body composition in adolescents with different body weights

PURPOSE

To evaluate associations between olfactory function, eating behavior, and characteristics of body composition in adolescents with different body weights.

METHODS

The study included 87 children aged 10-17 years with normal and excess body weight. The study group consisted of overweight and obese adolescents. All children underwent anthropometry with calculation of SDS body mass index (WHO Anthro Plus), body composition was assessed using Inbody 770, diagnosis of olfactory dysfunction was performed using a set of Sniffin Sticks (Odofin, Germany). The Dutch Eating Behavior Questionnaire was used for assessment of eating disorders. IBM SPSS. Statistics v.20 program was used for statistical analysis.

RESULTS

In adolescents with decreased sense of smell, regardless of SDS BMI, restrictive type of eating behavior was more common (p = 0.04). Among girls, hypoosmia was diagnosed in 21.7% (n = 10) of cases, being accompanied by a higher proportion of body fat, higher prevalence of emotionogenic type of eating behavior compared to girls without olfactory impairment, who, on the contrary, more frequently exhibited the restrictive type of eating disorder. Among boys, hypoosmia was found in 39% (n = 16) of cases. There were no statistically significant differences with the normoosmia subgroup in terms of eating behavior type and body composition parameters. Girls with hypoosmia showed positive associations between body fat percentage and discriminatory olfactory test results (r = 0.805; p = 0.020), externalizing type of eating behavior and BMI-FOR-AGE (r = 0.873; p = 0.005), body fat mass (r = 0.764; p = 0.027) and body fat percentage (r = 0.805; p = 0.016). The emotiogenic type of eating behavior showed significant correlations with total body phase angle (r = 0.805; p = 0.029), skeletal muscle mass (r = 0.791; p = 0.034). In boys with hypoosmia, positive associations were found between restrictive type of eating behavior and BMI-FOR-AGE (r = 0.784; p = 0.002), visceral fat area (r = 0.701; p = 0.008), body fat mass (r = 0.660; p = 0.014) and body fat percentage (r = 0.742; p = 0.004).

CONCLUSION

The results of this study suggest that hypoosmia is associated with changes in eating behavior and body composition in adolescents with different body weight, yet the direction of such casual relationship remains unclear.

Cooking and food skills and their relationship with adherence to the Mediterranean diet in young adults attending university: A cross-sectional study from Türkiye

Adherence to the Mediterranean diet has decreased among university students in many countries. Cooking skills (CS) and food skills (FS) have been suggested as potential targets for reversing this decline. This study aims to determine CS and FS and to examine their relationship with adherence to the Mediterranean diet in young adults attending university in Türkiye. This cross-sectional study was conducted between March 2022 and April 2022 at Ondokuz Mayıs University in Samsun, Türkiye, and included 859 university students (56.1% women; mean age 22.57 ± 2.75 years). Sociodemographic characteristics were collected. The CS and FS measure and the Mediterranean Diet Adherence Screener (MEDAS) were administered. The mean MEDAS, CS and FS scores were 4.77 ± 1.97, 59.10 ± 18.17 and 77.81 ± 22.27, respectively. Those with higher MEDAS scores (quartile three and quartile four-Q3 and Q4) had significantly higher CS scores than those with lower scores (Q1 and Q2), while those in the lowest quartile (Q1) had lower FS scores than all other quartiles (p < 0.001). Total scores of CS and FS positively, although weakly, correlated with MEDAS (r = 0.227 and r = 0.296; p < 0.001). Two separate models for CS and FS were analysed; along with access to kitchen facilities, CS and FS contributed the most variability, accounting for 8.9% and 11.8% of the variance in MEDAS, respectively (p < 0.001). This research indicates that higher CS and FS in university students are associated with higher adherence to the Mediterranean diet. It is also recommended that kitchen facilities be provided for them to practice these skills.

The effect of Virtual Reality Cycling with Music on simple obesity in college students: evidence from a randomized controlled trial in China

Background

Simple obesity has become an increasingly prevalent health concern among college students. Existing research indicates that traditional exercise methods may not sufficiently engage this population, particularly those facing barriers to regular physical activity. Thus, this study investigated how combining VR cycling with music influenced fat reduction in this population.

Method

This study recruited 78 Chinese college students with simple obesity (BMI ≥ 28 kg/m2) and randomly assigned them to either an experimental group (VR cycling combined with music, n = 41) or a control group (traditional cycling, n = 37). Both groups engaged in 12 weeks of cycling training, three times a week, for 45 min per session. Key physiological indicators, such as weight, BMI, waist circumference, and hip circumference, were measured at baseline, mid-intervention, and post-intervention.

Results

The VR cycling with music group exhibited significant improvements in key physiological metrics compared to the control group. Notable changes included a 4.1% reduction in weight, a 2.8% decrease in BMI, and a 2.8% reduction in waist circumference. Hip circumference also decreased by 2.5%, while the waist-to-hip ratio dropped by 0.016 units. Furthermore, the intervention led to a 7.2% increase in vital capacity, with all outcomes showing statistical significance (p<0.01). The experimental group also reported higher levels of enjoyment and engagement throughout the intervention period.

Conclusion

Participants in the experimental group experienced significant reductions in weight, BMI, and both waist and hip circumferences, as well as a notable improvement in vital capacity. The study highlights that combining virtual reality cycling with music resulted in more substantial weight loss and fat reduction in obese college students, compared to traditional cycling methods.

Adherence to the Mediterranean Diet in Association with Self-Perception of Dietary Behavior (Discrepancy between Self-Perceived and Actual Diet Quality): A Cross-Sectional Study among Spanish University Students of Both Genders

Background/Objectives: The Mediterranean diet (MD) is one of the most studied dietary patterns to date and is associated with multiple benefits for health and sustainability. However, paradoxically, adherence to the MD (AMD) has been gradually decreasing in native regions. It is necessary to identify the factors that influence AMD to reverse this trend and to mitigate the negative outcomes (for health and the environment) associated with westernized diets. The objective of this study was to assess how self-perception of dietary behavior influences AMD. Methods: During the 28-day repeated measurement cross-sectional study, participants' dietary information was obtained from an initial form which established the self-perception of dietary behavior and the e12HR application to establish actual food consumption by individuals. Using the dietary information from both sources, the AMD index was calculated (specifically, the Mediterranean diet Serving Score (MDSS) index). Two categories of self-perception of dietary behavior were defined: Normal/underestimation: difference (MDSS index from initial form-MDSS index from e12HR application) ≤0; and Overestimation: difference >0 (with three subcategories: low (difference = 1-5), moderate (difference = 6-10), high (difference = 11-15)). Results: 139 (111, women; 28, men) Spanish university students were studied, with 98.6% (99.1%, women; 96.4%, men) falling into the overestimation category (they overestimated their dietary behavior); these students had significantly lower MDSS indexes, mean = 6.7, than students in the normal/underestimation category, mean = 12.0. Within the overestimation category, there were significant differences in the MDSS index: low (mean = 8.1), moderate (mean = 6.7), and high (mean = 4.9) subcategories and also differences that were significant in women but not in men. Conclusions: Overestimation of dietary behavior could be associated with lower AMD in all Spanish university students and women.

Determination of the relationship between obesity prejudice status and eating behaviors of faculty of health sciences students

BACKGROUND

People living with obesity receive treatment services from health professionals for their weight or other health needs. In order for the students of the Faculty of Health Sciences, who will be a member of the health team in the future, to raise awareness of the society, it is necessary to first determine their obesity prejudices and eating habits.

METHODS

The study is a cross-sectional and descriptive research. The study data were collected from 406 students studying at the Faculty of Health Sciences by online questionnaire method using a personal characteristics identification form, GAMS 27-Obesity Bias Scale and University Students Eating Behavior Scale (USEBS). The data were analyzed with SPSS 26 statistical software.

RESULTS

In this study, all students were found to be prone to prejudice according to the mean total score of the Obesity Bias Scale and Obesity Bias Scale was higher in female students studying in perfusion department. In the sub-dimensions of the University Students Eating Behavior Scale, the enjoyment of food score was found to have the highest mean score.

CONCLUSION

According to the results of the study, there is a need to develop educational planning that will both increase the awareness of university students about the relationship between eating behaviors and obesity and eliminate obesity prejudice tendencies due to the fact that they are educated to provide services in the field of health.

Prevalence and determinants of overweight or obesity among medical students over a 2-year observation

Introduction

University students are a special population group characterized by changes in BMI values over the subsequent years of education, with an upward tendency to BMI. The presented study aims to evaluate the prevalence of overweight and obesity and their determinants in medical students during the 2-year follow-up observation.

Materials and methods

We analyzed data collected from the first follow-up of the cohort study named "POLLEK" conducted among medical students at the Medical University of Silesia in Katowice. Students were followed at two points of time: in their inaugural year of studies (the academic year 2021/2022, T1, N = 427), and subsequently in their second year (the academic year 2022/2023, T2, N = 335).

Results

In the initial year of evaluation, 371 individuals (86.9%) exhibited normal body weight, 47 (11.0%) were overweight, and 9 (2.1%) were classified as obese. Subsequent assessments during the second year revealed the following distribution: 277 students (84.2%) with normal body weight, 40 (12.2%) classified as overweight, and 12 (3.6%) identified as obese. In summary, regardless of the academic year, an increased risk of being overweight or obese was significantly associated with dissatisfaction with personal health, financial strain, and a diet abundant in animal products.

Conclusion

The results of our study confirmed an increase in the prevalence of overweight or obesity among medical students during the 2-year follow-up observation. Significant determinants of overweight or obesity among medical students were: dissatisfaction with individual health status, male sex, financial deficiencies, and a diet abundant in meat consumption.

Combination of Machine Learning Techniques to Predict Overweight/Obesity in Adults

(1) Background: Artificial intelligence using machine learning techniques may help us to predict and prevent obesity. The aim was to design an interpretable prediction algorithm for overweight/obesity risk based on a combination of different machine learning techniques. (2) Methods: 38 variables related to sociodemographic, lifestyle, and health aspects from 1179 residents in Madrid were collected and used to train predictive models. Accuracy, precision, and recall metrics were tested and compared between nine classical machine learning techniques and the predictive model based on a combination of those classical machine learning techniques. Statistical validation was performed. The shapely additive explanation technique was used to identify the variables with the greatest impact on weight gain. (3) Results: Cascade classifier model combining gradient boosting, random forest, and logistic regression models showed the best predictive results for overweight/obesity compared to all machine learning techniques tested, reaching an accuracy of 79%, precision of 84%, and recall of 89% for predictions for weight gain. Age, sex, academic level, profession, smoking habits, wine consumption, and Mediterranean diet adherence had the highest impact on predicting obesity. (4) Conclusions: A combination of machine learning techniques showed a significant improvement in accuracy to predict risk of overweight/obesity than machine learning techniques separately.

Association of Mediterranean diet with sleep quality, depression, anxiety, stress, and body mass index in university students: A cross-sectional study

Background: The Mediterranean diet (MD) has many beneficial effects on health. However, compliance with MD is decreasing among university students. Aim: This study aims to investigate compliance with the MD and the association of MD with sleep quality, depression, anxiety, stress, and body mass index (BMI) among university students. Methods: This cross-sectional study included 750 students of Ondokuz Mayıs University, a state university in Samsun, Türkiye. Sociodemographic data and self-reported anthropometric data (weight and height) were recorded using a survey. The Mediterranean diet quality index for children and adolescents (KIDMED), the Pittsburgh sleep quality index (PSQI), and the depression anxiety stress scale-42 (DASS-42) were self-administered. Results: Most students (59.2%) had poor KIDMED adherence. Compared to poor adherers, those with good adherence to the KIDMED had significantly lower depression scores (in males and females). Higher adherence to the KIDMED was correlated with lower depression and stress levels (in males and females) and lower PSQI scores (lower sleep disturbances) in females. The KIDMED scores of overweight females were greater than those of underweight females. Conclusion: University students show poor adherence to the MD. Low adherence to the MD may have a negative impact on depression, stress, and sleep quality. This study suggests that interventions to promote MD may help improve university students' sleep disturbances and mental health.

Association of health behaviors, dietary habits, and oral health with weight gain after 20 years of age in community-dwelling Japanese individuals aged 40 years and older: a cross-sectional study

OBJECTIVES

This cross-sectional study investigated the factors associated with weight gain ≥ 10 kg after 20 years of age in the general Japanese population, with a focus on the number of teeth.

MATERIALS AND METHODS

We included individuals aged ≥ 40 years from Yamagata prefecture, Japan from 2017-2021. A postal survey was conducted using a self-administered questionnaire; 5,940 participants were included in the final analysis. The questionnaire included items on lifestyle factors, medical history, physical and mental conditions, oral health, and dietary intake. A multivariate logistic regression analysis was used to identify independent associations between weight gain ≥ 10 kg after 20 years of age and various parameters; adjusted odds ratios (ORs) and 95% confidence intervals (CIs) were estimated.

RESULTS

Less than 20 teeth, male sex, drinking habit frequency, eating very fast or fast, and a higher frequency of eating-away-from-home were significant factors associated with weight gain ≥ 10 kg after 20 years of age; individuals with < 20 versus > 20 teeth exhibited a 1.35-fold higher OR (95% CI 1.15-1.59; p < 0.01).

CONCLUSIONS

Our results suggest that having < 20 teeth may affect weight gain ≥ 10 kg after 20 years of age. However, owing to the cross-sectional study design, causality could not be determined. Therefore, maintaining healthy lifestyle behaviors to avoid tooth loss may also affect weight gain ≥ 10 kg after 20 years of age.

CLINICAL RELEVANCE

Having < 20 teeth has the potential to affect long-term weight gain after 20 years of age.

Prevalence and factors associated with metabolic syndrome in university students and academic staff in Bangladesh

Metabolic syndrome (MetS) is a group of medical conditions that increase the risk of cardiovascular disease, stroke, and type 2 diabetes. While there are numerous studies on the prevalence of MetS in the general adult population worldwide, limited information exists regarding its prevalence among university students and academic staff. This study aimed to determine the prevalence of MetS and associated risk factors among Bangladesh university students and academic staff. For this cross-sectional study, 583 participants were randomly selected from university students (n = 281) and academic staff (n = 302) in Bangladesh. The participants' fasting blood samples were collected, and their serum lipid profile levels, fasting blood glucose, and other parameters were measured using standard methods. MetS was defined according to the NCEP-ATP III model guidelines. Additionally, a questionnaire was administered to the participants to gather information on socio-demographics, lifestyle risk behaviours, and personal medical history. Multivariate logistic regression models were used to determine the risk factors associated with MetS. Overall, the prevalence of MetS was 27.7% in students and 47.7% in staff. There was a significant difference (p < 0.01) in MetS prevalence between male students (34.8%) and female students (17.2%). In contrast, it was comparatively higher in female staff (52.3%) than in male staff (45.8%), although the difference was not statistically significant. The prevalence of MetS and its components increased with age in student and staff groups. The most common component of MetS was low levels of HDL-C, which affected 78% and 81.4% of the students and staff, respectively. Logistic regression modelling showed that increased age, BMI, hypertension, dyslipidemia, low physical activity, and smoking were significantly associated with MetS in students (at least p < 0.05 for all cases). On the other hand, increased age and BMI, hypertension, and dyslipidemia were significantly associated with MetS in academic staff (at least p < 0.05 for all cases). In conclusion, this study indicates a high prevalence of MetS in university students and staff in Bangladesh. Age, BMI, hypertension and dyslipidemia were independently associated with the risk of MetS in both groups. The findings emphasize the importance of interventions for students and staff in academic settings in Bangladesh. It is crucial to implement health promotion activities such as healthy diet and exercise programs more rigorously. Further research with more representative samples is needed to get more clear insights into MetS prevalence in this particular population subgroup for targeted interventions.

Association between Physical Activity and Sitting Time Related to Excess Body Weight in Brazilian University Students

High exposure to sedentary behavior and lower levels of physical activity can lead to excess body weight (EBW). The aim of this study was to estimate the prevalence of EBW and the direct association under the condition of sociodemographic, university, and behavioral moderating characteristics, between physical activity and sitting time related to EBW in Brazilian university students. A cross-sectional study was carried out with 1,110 university students from a federal public institution in Minas Gerais, Brazil. The outcome was the EBW (body mass index: ≥25.0 kg/m2) and the independent variables were physical activity (insufficiently active and active) and sitting time (<6 h/day; ≥6 h/day). Association analyses were estimated via odds ratio (OR) using binary logistic regression. The significance level was 5%. The prevalence of EBW was 27.8%. No direct association was observed between physical activity and time sitting related to EBW. However, insufficiently active university students were more likely to have EBW (OR = 1.91; 95% CI: 1.06-3.47) when they did not consume alcoholic beverages, and university students with a sitting time of ≥6 h/day had lower chances of having EBW (OR = 0.62; 95% CI: 0.40-0.95) when they had spent more time at university (3 years or more). It is concluded that the prevalence of EBW in university students was high and there was no direct association between physical activity and sitting time; however, alcohol consumption and university time moderated the association with higher and lower chances of occurrence of EBW in university students, respectively.

Macronutrient Intake, Sleep Quality, Anxiety, Adherence to a Mediterranean Diet and Emotional Eating among Female Health Science Undergraduate Students

INTRODUCTION

COVID-19 provoked a myriad of challenges for people's health, poor life satisfaction and an unhealthy diet that could be associated with serious negative health outcomes and behaviours. University is a stressful environment that is associated with unhealthy changes in the eating behaviours of students. The association between diet and mental health is complex and bidirectional, depending on the motivation to eat; emotional eaters regulate their emotions through the increased consumption of comfort foods.

OBJECTIVE

The aim of this study was to compare the nutritional habits, alcohol consumption, anxiety and sleep quality of female health science college students.

MATERIAL AND METHODS

A cross-sectional study of 191 female undergraduate students in Madrid was used. Their body mass index and waist hip ratio were measured. The questionnaires used included the Mediterranean Diet Adherence test, AUDIT, Emotional Eater Questionnaire, Pittsburgh Sleep Quality Index, and Food Addiction, Perceived Stress Scale and STAI questionnaires.

RESULTS

We observed a high intake of protein, fat, saturated fatty acids and cholesterol. Overall, 9.5% never had breakfast, and 66.5% consciously reduced their food intake. According to Pittsburgh Sleep Quality Index, they mainly slept 6-7 h, and 82% presented with a poor sleep quality; 13.5% presented moderate-high food addiction, and 35% had moderate Mediterranean Diet Adherence score.

CONCLUSION

Female students' macronutrient imbalances were noted, with a high-level protein and fat intake diet and a low proportion of carbohydrates and fibre. A high proportion of them need alcohol education and, depending on the social context, they mainly drank beer and spirits.

Effectiveness of a Smartphone App (e-12HR) in Improving Adherence to the Mediterranean Diet in Spanish University Students by Age, Gender, Field of Study, and Body Mass Index: A Randomized Controlled Trial

There is an urgent need to implement intervention programs to promote adherence to the Mediterranean diet (AMD) in university students to prevent non-communicable diseases. A powerful tool for this is smartphone apps. Furthermore, it is necessary to determine the subgroups that are most likely to benefit from these technologies. The objective is to evaluate the effectiveness of an app (e-12HR) at improving AMD in a sample of Spanish university students and different strata. The study method was a controlled and randomized clinical trial over a four-week follow-up period and involving 385 participants (76.9% women). The participants were in two parallel groups: the control group (CG) and the intervention group (IG), with only the IG receiving feedback to improve their AMD. There were significant statistical improvements (with higher values in the IG) at week four, after no significant statistical differences at baseline (Week One): in the whole sample: +25.7% AMD index and +74.5% percentage with moderate/high AMD index. In the subgroups, seven of eight subgroups, ranging in AMD index from +17.8% (≥20 years) to +33.0% (<20 years); and for males, in weeks two (+27.9%) and three (+23.9%), but not at week four. In conclusion, e-12HR could improve AMD among university students (in the total sample and all subgroups, except ≥25 kg/m2).

Research on the Relationship between Physical Literacy, Physical Activity and Sedentary Behavior

During the COVID-19 pandemic, college students' health-related physical activity and physical literacy aroused widespread concern. This study evaluated the relationship among physical literacy (PL), sedentary behavior (SB), light physical activity (LPA), and moderate-to-vigorous physical activity (MVPA); we further explored whether LAP and SB mediated the association between PL and MVPA.

METHODS

This study was based on a cross-sectional survey of Chinese college students. The Perceived Physical Literacy Instrument Scale (PPLI-SC) and International Physical Activity Questionnaire Short Form (IPAQ-SF) were used to investigate the PL, MVPA, LPA, and SB.

RESULTS

There were 2996 valid questionnaires with 829 boys and 2167 girls. The MVPA, LPA, and PL of boys were significantly higher than girls, while the SB values were significantly lower in girls (p&nbsp;< 0.01). The correlation analysis showed that there was a significant correlation between the two indexes except for SB and LPA. Path analysis shows that PL directly, significantly, and positively affects MVPA. PL reduces SB (β = -0.085, p < 0.001) and increases LPA (β = 0.097, p < 0.001). The total mediation effect accounted for 14.014%, and the mediation effects of SB and LPA accounted for 4.417% and 9.597%, respectively.

CONCLUSIONS

LPA and SB partially mediated the relation between PL and MVPA. SB and LPA partially explain the impact of PL on MVPA. The findings suggest that managing SB and improving LPA could play a significant indirect role in increasing the positive effect of PL on MVPA and that increasing the opportunities for LPA increased the MVPA for Chinese college students.

Diet Quality among Students Attending an Australian University is Compromised by Food Insecurity and Less Frequent Intake of Home Cooked Meals. A Cross-Sectional Survey Using the Validated Healthy Eating Index for Australian Adults (HEIFA-2013)

Poor diet quality is commonly reported in young adults. This study aimed to measure the diet quality of students attending a large Australian university (including domestic and international students), and to examine the effect of food security status and other key factors likely to impact their diet quality. Using the Automated Self-Administered 24-h recall Australian version, a cross-sectional survey collected dietary recalls from domestic and international students in one university in Sydney. Diet quality was assessed using the validated Healthy Eating Index for Australian Adults (HEIFA-2013) which gives a score out of 100. Food security status was measured by the 18-item Household Food Security Survey Module. Differences in the mean HEIFA-2013 scores by student characteristics were determined by analysis of covariance. A total of 141 students completed one dietary recall. The mean HEIFA-2013 score for students was low (mean 52.4, 95% CI 50.0–54.8). Food-insecure students had a poorer diet quality (mean 43.7, 95% CI 35.7–51.8) than their food-secure peers (mean 53.2, 95% CI 50.8–55.7, p = 0.027). The mean HEIFA-2013 score was similar in domestic (mean 52.5, 95% CI 49.9–55.2) and international students (mean 51.9, 95% CI 46.3–57.5, p = 0.845). Those reporting self-perceived excellent cooking skills and higher cooking frequency had better diet quality. Interventions to improve food and nutrition knowledge and skills and address food insecurity may help tertiary education students cook more frequently and achieve better diet quality.

Mediterranean Diet, a Posteriori Dietary Patterns, Time-Related Meal Patterns and Adiposity: Results from a Cross-Sectional Study in University Students

The transition to university is connected to potentially obesogenic dietary changes. Our aim was to assess the relation of Mediterranean diet adherence, and a posteriori dietary and meal patterns with adiposity in Greek students at the University of the Peloponnese. A total of 346 students (269 women) participated. Anthropometry was performed, and a food frequency questionnaire was administered. The MedDietScore was higher in women and was not linearly related to adiposity. Principal component analysis revealed six patterns: (1) legumes/vegetables/fruits/tea/dairy/whole grains, (2) juice/sodas/liquid calories, (3) olive oil/fats, (4) meat/poultry/fish, (5) alcohol/eggs/dairy and (6) fast foods/sweets. Patterns 4 and 6 were related to overweight/obesity probability (OR = 1.5, 95% CI: 0.995-2.538 and OR = 2.5, 95% CI: 1.07-6.06, respectively) and higher waist circumference (men). Men "early eaters" (breakfast/morning/afternoon snack) had a higher MedDietScore and lower overweight probability (OR = 0.47, 95% CI: 0.220-1.020). Poor meal and dietary patterns relate to overweight and central obesity, which is important for targeted health promotion programs.

Skipping Breakfast and Incidence of Frequent Alcohol Drinking in University Students in Japan: A Retrospective Cohort Study

Frequency of alcohol drinking is a potential predictor of binge drinking of alcohol, a serious social problem for university students. Although previous studies have identified skipping breakfast as a predictor of various health-compromising behaviors and cardiometabolic diseases, few studies have assessed the association between skipping breakfast and the incidence of frequent alcohol drinking. This retrospective cohort study included 17,380 male and 8799 female university students aged 18–22 years admitted to Osaka universities between 2004 and 2015. The association between breakfast frequency (eating every day, skipping occasionally, and skipping often/usually) and the incidence of frequent alcohol drinking, defined as drinking ≥4 days/week, was assessed using multivariable-adjusted Cox proportional hazards models. During the median observational period of 3.0 years, 878 (5.1%) men and 190 (2.2%) women engaged in frequent alcohol drinking. Skipping breakfast was significantly associated with the incidence of frequent alcohol drinking (adjusted hazard ratios [95% confidence interval] of eating every day, skipping occasionally, and skipping often/usually: 1.00 [reference], 1.02 [0.84–1.25], and 1.48 [1.17–1.88] in men; 1.00 [reference], 1.60 [1.03–2.49], and 3.14 [1.88–5.24] in women, respectively). University students who skipped breakfast were at a higher risk of frequent alcohol drinking than those who ate breakfast every day.

Knowledge and Attitudes Towards Obesity and Bariatric Surgery in University Students: a National Survey

BACKGROUND

Obesity has become a noticeable public health problem, especially in the young population. Bariatric surgery is growing in China but it is still new to the general public. Knowledge and attitudes towards obesity and bariatric surgery in university students are important to national health decision-making.

OBJECTIVES

To study the knowledge and attitudes towards obesity and bariatric surgery among Chinese university students.

METHODS

A self-designed questionnaire was distributed to university students to fill in online from June to July 2021.

RESULTS

A total of 3199 questionnaires were received, with an effective rate of 98.58% (3154 questionnaires). 65.44% of whom had normal BMI and 12.14% of whom were overweight or in obesity. More than 80% of them had a high knowledge of the common causes and complications of obesity but lacked knowledge of the relationship between obesity and bone and joint, tumor or cancer, and reproductive diseases. 51.55% of them thought they needed to lose weight, especially female students (P < 0.01). Only 39% had regular physical exercise habits, 58.62% of them could reasonably control their diet, and more than 2/3 of them (67.82%) often stayed up late. Safety (29.77%) and effectiveness (29.3%) of bariatric surgery were not well accepted. Among medical students, education positively affected knowledge and attitudes towards bariatric surgery (P < 0.05). Mass media and social platforms were the main sources for obtaining obesity and weight-loss information.

CONCLUSIONS

Chinese university students have insufficient knowledge of obesity and related complications, lack of scientific management of their own weight, and poor acceptance of bariatric surgery. More education is needed on this issue.
