Physical activity and mental health

The association and impact of psychological and social factors on physical activity levels amongst women in the Australian WATCH longitudinal study

INTRODUCTION

Regular physical activity is important for physical and mental health. Despite the benefits, over 30% of the global population do not meet the World Health Organisation (WHO) physical activity guidelines, with the risk greater for women, especially during reproductive years, compared to men. However, women of this age face many barriers to participation and there are significant gaps in our understanding of the impact of psychological and social adversity on participation levels. This study aimed to identify adversity factors associated with physical inactivity or reduced activity.

METHODS

Data from 623 women in the WATCH prospective cohort study, a representative sample of women recruited during the antenatal phase, including half from refugee backgrounds, were analyzed to assess the association between prior theoretically supported adversities (e.g., financial stress, living difficulties, intimate partner violence, refugee status and mental health issues) and current physical activity levels. Physical activity was assessed via self-report, using the Physical Activity Vital Sign. A categorical indicator was constructed to describe participants average activity per week based on WHO physical activity and muscle strengthening guidelines; inactive, below recommendation and at or exceeds recommendation. Binary multinomial logistic regression analyses were conducted to examine the crude and demographically adjusted association between each variable and physical activity with. At or exceeds recommendation as the reference group.

RESULTS

N = 122 (20 %) of the total sample reported no physical activity (0 min) during the previous week. Meanwhile, n = 445 (71 %) engaged in some physical activity but did not meet the recommended guidelines, and n = 56 (9 %) met the guidelines. The odds of being inactive were significantly higher for women from refugee backgrounds OR = 5.79, 95 % CI 2.70 to 12.41, p < .001. In addition, who who have experienced previous trauma, living difficulties, or mental health symptoms had significantly higher odds of being inactive.

CONCLUSION

High rates of physical inactivity among reproductive-age women were observed. Interventions aimed at increasing physical activity should consider adversity factors identified in this study which impact participation levels, including refugee status, trauma exposure, intimate partner violence, living difficulties, and mental disorder symtoms in their design and implementation.

Ozone concentration, physical activity, and emotional and behavioral problems in children and adolescents

BACKGROUND

No prior study has examined the mutual association of long-term outdoor ozone (O3) concentration and physical activity (PA) with emotional and behavioral problems (EBPs) in children and adolescents. This study aims to investigate the association between long-term outdoor O3 concentration and the risk of EBPs in children and adolescents and further explore whether increased PA levels modify this association.

METHODS

Data were obtained from the 2020 wave follow-up examination of an ongoing prospective cohort study (COHERENCE project) in Guangzhou, China. A total of 419,033 children aged 6-17-year-old were included. Annual average outdoor O3 concentrations were obtained from the China High Air Pollutants (CHAP) dataset based on participants' residential addresses. PA levels were identified using the International Physical Activity Questionnaire Short Form (IPAQ). EBPs were assessed by the Chinese Parent-Report Strengths and Difficulties Questionnaire (SDQ-P).

RESULTS

Each interquartile range (IQR) increase in outdoor O3 concentration was associated with an increased odds ratio (OR) for abnormal emotional problems (OR: 1.024, 95% CI: 1.010-1.038), conduct problems (OR: 1.015, 95% CI: 1.002-1.029), peer relationship problems (OR: 1.029, 95% CI: 1.006-1.052), prosocial behavior (OR: 1.023, 95% CI: 1.012-1.034), total difficulties (OR: 1.024, 95% CI: 1.010-1.038), and internalizing behavior (OR: 1.039, 95% CI: 1.026-1.053), in fully adjusted models. The highest OR for abnormal EBPs was observed in children with low PA levels, in combination with high O3 concentration.

CONCLUSION

This study identified that long-term outdoor O3 concentration is associated with an increased risk of EBPs in children and adolescents, with higher PA levels attenuating these risks.

Interventions and behaviour change techniques for improving physical activity level in working-age people (18-60 years) with type 2 diabetes: A systematic review and network meta-analysis

BACKGROUND

The escalating prevalence of type 2 diabetes within the working-age population (18-60 years) imposes a substantial societal burden. Whilst physical activity is crucial for diabetes management, limited evidence exists to inform optimal strategies for promoting physical activity in this population. We aimed to evaluate and compare the effect of interventions for increasing physical activity in working-age adults with type 2 diabetes.

METHODS

We searched Web of Science, the Cochrane Library, Medline, Embase, PsycINFO, ClinicalTrials.gov, and ICTRP from inception to April 30, 2023. Randomised controlled trials that reported the effect of interventions (education, training or behavioural) to promote physical activity (either self-reported or objective) in people aged 18-60 years were included. Two independent reviewers conducted summary data extraction and quality assessment. Pairwise random-effects, Frequentist network meta-analyses, and subgroup analysis were used to obtain pooled effects.

RESULTS

A total of 52 trials were included in this systematic review. Compared to control group, the physical activity interventions demonstrated statistically significant effects on objectively measured physical activity (SMD 0.77, 95 % CI 0.27-1.27), self-reported physical activity (SMD 0.88, 95 % CI 0.40-1.35), and overall physical activity (SMD 0.82, 95 % CI 0.48-1.16); a statistically and clinically meaningful reduction on glycated haemoglobin A1c (HbA1c) was also identified (MD -0.50 %, 95 % CI -0.66, -0.35). In terms of intervention types, education interventions exerted the largest effect on objectively measured physical activity; however, psychological interventions had the largest effects on overall physical activity compared to other intervention types. Four behaviour change techniques were related to statistically significant reduction in HbA1c: goal setting (outcome), information about health consequences, demonstration of the behaviour, and prompts/cues. Subgroup analysis showed that delivery mode, intervention setting, and facilitator were associated with statistically significant effect on physical activity and HbA1c.

CONCLUSIONS

Psychologically modelled education incorporating behaviour change techniques may be the most beneficial way to promote physical activity and glycaemic control in working-age adults with type 2 diabetes. Delivery mode, intervention setting, and facilitator type should be considered when designing interventions for improving physical activity level in working-age people with type 2 diabetes.

Study protocol: A national cross-sectional study on psychology and behavior investigation of Chinese residents in 2023

Introduction

This study protocol specifies the primary research line and theoretical framework of the 2023 Survey of the Psychology and Behavior of the Chinese Population. It aims to establish a consistent database of Chinese residents' psychological and behavioral surveys through multi-center and large-sample cross-sectional surveys to provide robust data support for developing research in related fields. It will track the public's physical and psychological health more comprehensively and systematically.

Methods

The study was conducted from June 20, 2023 to August 31, 2023, using stratified and quota sampling methods. A total of 150 cities across 800 communities/villages were surveyed, selected from China (Despite extensive coordination, we have been unable to contact our counterparts in the Taiwan region of China to obtain relevant statistical data). The questionnaires were distributed to the public one-on-one and face-to-face by trained surveyors. The questionnaires included basic information about the individual, personal health status, basic information about the family, the social environment in which the individual lives, psychological condition scales, behavioral level scales, other scales, and attitudes towards topical social issues. Supervisors conducted quality control during the distribution process and returned questionnaires, logically checked and cleaned for data analysis.

Discussion

Data collection has been finished, and scientific outputs based on this data will support the development of health promotion strategies in China and globally. In the aftermath of the pandemic, it will guide policymakers and healthcare organizations to improve their existing policies and services to maximize the physical and mental health of the Chinese population.

Trial Registration

This study was filed in the National Health Security Information Platform (Record No.: MR-37-23-017876) and officially registered in the China Clinical Trials Registry (Registration No.: ChiCTR2300072573).

Development and initial validation of the group exercise motivation scale and associated factors in an Asian population

BACKGROUNDS

Physical activity is crucial in health promotion. Exercise in groups can strengthen the benefits of exercise itself. However, the scale measuring the motivation for group exercise is scare.

AIM

To develop and preliminarily validate the Group Exercise Motivation Scale (GEMS) in a global Asian population.

METHODS

A total of 1021 participants from seven regions across the world were recruited. Based on the theory of planned behavior, we developed an initial 20-item scale for the measurement of group exercise motivation and conducted an exploratory factor analysis (EFA). Then, a confirmatory factor analysis (CFA) was performed to replicate the factor structure obtained through EFA with a refined 15-item scale, among 510 and 511 participants, respectively.

RESULTS

Four dimensions have been derived including personal attitude, subjective norms, perceived behavioral control, and behavioral intention. The GEMS showed acceptable factorial validity, satisfactory reliability (Cronbach's α 0.779 and McDonald's omega 0.745), and no floor/ceiling effect. The scale was developed in Chinese language.

CONCLUSIONS

The GEMS has utility as an assessment for group exercise motivation. This study provides evidence for future longitudinal studies to evaluate the effectiveness of group exercise in the field of public health.

Sufficient sleep and physical activity can relieve the effects of long-term exposure to particulate matter on depressive symptoms among 0.31 million children and adolescents from 103 counties in China

BACKGROUND

Although long-term exposures to air pollutants have been linked to mental disorders, existing studies remain limited and inconsistent. We investigated the relationship between exposure to particulate matter (PM) and depressive symptoms, as well as the potential role of sleep duration and physical activity.

METHOD

Using the surveillance data (2019 to 2022) of common diseases and risk factors among 312,390 students aged 10-25 years, logistic regression, generalized liner model (GLM) and restricted cubic spline (RCS) were employed to investigate the relationship between long-term exposure to PM and depressive symptoms.

RESULT

Significant associations were found between PM1 (OR = 1.21, 95 % CI: 1.12-1.32), PM2.5 (OR = 1.24, 95 % CI: 1.19-1.38), and PM10 (OR = 1.87, 95 % CI: 1.69-2.07) and increased risks of depressive symptoms. Sleep duration and physical activity relieved these associations. The odds ratios (ORs) of PM1, PM2.5, and PM10 on depressive symptoms were lower in group with sufficient sleep (1.02 vs. 1.49, 1.20 vs. 1.80, 2.15 vs. 2.23), lower in group with high level MVPA (1.13 vs. 1.48, 1.14 vs. 1.58, 1.85 vs. 2.38), and lower in group with high level outdoor activity (1.19 vs. 1.55, 1.23 vs. 1.63, 1.83 vs. 2.72).

LIMITATIONS

Conclusions about causality remain speculative because of the cross-sectional design.

CONCLUSION

Sufficient sleep duration and outdoor activity may mitigate the decline in mental health among adults in developing countries caused by long-term exposure to PM. This contribution enhanced our understanding of the mechanisms linking air pollution to mental health.

Assessing the Relationships between Physical Activity, a Healthy Life, and Personal Happiness in European Union Countries

Background: Maintaining a physically active lifestyle is a determinant factor of a healthy life and personal happiness. Meanwhile, physical inactivity remains a significant issue, resulting in negative consequences for public health. Objectives: This paper investigates the relationships between physical activity, physical inactivity, a healthy life, life expectancy, and personal happiness in European Union (EU) countries. Methods: This empirical study uses an artificial neural network and cluster analysis to analyze and interpret data from 27 EU countries. Artificial neural network analysis enables the assessment of the relationships between physical activity and inactivity, a healthy life, and personal happiness, while cluster analysis identifies groups of EU countries based on physical activity, healthy life, and personal happiness indicators. Results: The results show significant positive links between physical activity and improvements in healthy living and personal happiness. Conclusions: This study highlights considerable variations among EU countries regarding the levels of physical activity, healthy living, and personal happiness, emphasizing the importance of promoting physical activity to enhance public health and overall well-being. The findings suggest the need to develop customized policies that address country-specific factors and promote an active lifestyle.

Correspondence between the Simple Physical Activity Questionnaire (SIMPAQ) and accelerometer-based physical activity in inpatients treated for major depressive disorders in comparison to non-depressed controls

Introduction

Major depressive disorders (MDD) are a leading health concern worldwide. While first line medication treatments may fall short of desired therapeutic outcomes, physical activity (PA) interventions appear to be a promising and cost-effective add-on to improve symptoms of depression. This study aimed to address challenges in the assessment of PA in inpatients treated for MDD by examining the correspondence of self-reported and accelerometer-based PA.

Methods

In 178 inpatients treated for MDD (mean age: M = 41.11 years, SD = 12.84; 45.5% female) and 97 non-depressed controls (mean age: M = 35.24 years, SD = 13.40; 36.1% female), we assessed self-reported PA via the Simple Physical Activity Questionnaire (SIMPAQ) for one week, followed by a week where PA was monitored using an accelerometer device (Actigraph wGT3x-BT). Additionally, we examined correlations between PA levels assessed with the SIMPAQ and exercise determinants in both groups.

Results

Descriptively, inpatients treated for MDD showed lower levels of light PA on accelerometer-based measures, whereas they self-reported increased levels of certain types of PA on the SIMPAQ. More importantly, there was only a small degree of correspondence between self-reported and actigraphy-based PA levels in both in patients (r = 0.15, p < 0.05) and controls (r = 0.03, ns). Only few significant correlations were found for self-reported PA (SIMPAQ subscores) and perceived fitness, whereas self-reported PA and estimated VO2max were unrelated. Furthermore, only weak (and mostly statistically non-significant) correlations were found between exercise determinants and SIMPAQ-based exercise behavior in both populations.

Discussion

Our findings emphasize the intricate challenges in the assessment of PA, not only in inpatients treated for MDD, but also in non-depressed controls. Our findings also underline the necessity for a diversified data assessment. Further efforts are needed to refine and improve PA questionnaires for a more accurate data assessment in psychiatric patients and healthy controls.

The development of an EU-wide nutrition and physical activity expert knowledge base to support a personalised mobile application across various EU population groups

A healthy lifestyle comprising regular physical activity and an adequate diet is imperative for the prevention of non-communicable diseases such as hypertension and some cancers. Advances in information computer technology offer the opportunity to provide personalised lifestyle advice directly to the individual through devices such as smartphones or tablets. The overall aim of the PROTEIN project (Wilson-Barnes et al., 2021) was to develop a smartphone application that could provide tailored and dynamic nutrition and physical activity advice directly to the individual in real time. However, to create this mobile health (m-health) smartphone application, a knowledge base of reference ranges for macro-/micronutrient intake, anthropometry, biochemical, physiological and sleep parameters was required to underpin the parameters of the recommender systems. Therefore, the principal aim of this emerging research paper is to describe the process by which experts in nutrition and physiology from the PROTEIN consortium collaborated to develop the nutritional and physical activity requirements, based upon existing recommendations, for 10 separate population groups living within the EU including, but not limited to healthy adults, adults with type 2 diabetes mellitus, cardiovascular disease, excess weight, obesity and iron deficiency anaemia. A secondary aim is to describe the development of a library of 24-h meal plans appropriate for the same groups and also encompassing various dietary preferences and allergies. Overall, the consortium devised an extensive nutrition and physical activity knowledge base that is pertinent to 10 separate EU user groups, is available in 7 different languages and is practically implemented via a library of culturally appropriate, 24-h meal plans.

Feasibility and acceptability of a home-based virtual group exercise program in global Asian adult population: Baseline characteristics of a cohort study

BACKGROUND

To determine the potential influence of a home-based virtual group exercise on people's long-term overall health consequences in global Asian population.

METHODS

We recruited 1021 participants from more than 7 regions across the globe including Taiwan, Malaysia, Singapore, Hong Kong, United States, Canada, Europe, and other regions. All the participants attended the virtual group Qigong exercise 60-minute bi-weekly with instructors for 6 months from June 2022 to December 2022. The physical, mental, and social well-being and other variables were measured via online questionnaires.

RESULTS

The majority were 51 to 65 (50.6%) years old, female (90.2%), married (68.5%), and came from Taiwan (48.9%). Older adults had higher scores on measures of overall health and exercise adherence, and lower scores on measures of sleep quality and depressive symptoms compared with younger counterparts (P < .05). Most of them (95.3%) acknowledged that the improvement of health status was their motivating factor for exercise. Eighty nine percent of the participants believed that social media played an important role in this exercise program.

CONCLUSION

This study will suggest such approach has great potential to reduce health disparities and can be implemented to underserved population who has limited recourses to join in-person exercise program.

Evaluating the Effects of an Enhanced Strength Training Program in Remote Cardiological Rehabilitation: A Shift from Aerobic Dominance-A Pilot Randomized Controlled Trial

(1) Background: Cardiac rehabilitation often emphasizes aerobic capacity while overlooking the importance of muscle strength. This study evaluated the impact of an enhanced remote strength training program (RCR-ST) on cardiac rehabilitation. (2) Methods: In this randomized prospective study (RCT registration number SMC-9080-22), 50 patients starting cardiac rehabilitation were assessed for muscle strength, aerobic capacity, and self-reported outcomes at baseline and after 16 weeks. Participants were divided into two groups: the RCR-ST group received a targeted resistance training program via a mobile app and smartwatch, while the control group received standard care with general resistance training advice. (3) Results: The RCR-ST group demonstrated significant improvements in muscle endurance, notably in leg extension and chest press exercises, with increases of 92% compared to 25% and 92% compared to 13% in the control group, respectively. Functional assessments (5-STS and TUG tests) also showed marked improvements in agility, coordination, and balance. Both groups improved in cardiorespiratory fitness, similarly. The RCR-ST group reported enhanced physical health and showed increased engagement, as evidenced by more frequent use of the mobile app and longer participation in the rehabilitation program (p < 0.05). (4) Conclusions: Incorporating a focused strength training regimen in remote cardiac rehabilitation significantly improves muscle endurance and patient engagement. The RCR-ST program presents a promising approach for optimizing patient outcomes by addressing a crucial gap in traditional rehabilitation protocols that primarily focus on aerobic training.

How Does Physical Activity Enhance the Subjective Well-Being of University Students? A Chain Mediation of Cognitive Reappraisal and Resilience

BACKGROUND

Regular physical activity is an effective means to enhance university students' subjective well-being. However, current research needs to understand how physical activity enhances the subjective well-being of Chinese university students. Therefore, the study investigated the mechanism of physical activity's impact on university students' subjective well-being and the mediating roles of cognitive reappraisal and resilience in this mechanism.

METHODS

The physical activity scale, subjective well-being scale, cognitive reappraisal scale and resilience scale were used to investigate 1350 university students, and the relationship between physical activity, cognitive reappraisal, resilience and university students' subjective well-being was verified through correlation analysis, regression analysis and a Bootstrap method.

RESULTS

(1) There is a significant positive correlation between physical activity, cognitive reappraisal, resilience and university students' subjective well-being (p < 0.01); (2) physical activity, cognitive reappraisal and resilience all have a significant positive effects on university students' subjective well-being (p < 0.01); (3) cognitive reappraisal and resilience have significant mediating roles in the process of physical activity affecting university students' well-being, with mediating-effect values of 0.052 and 0.285; (4) the chain-mediating role of cognitive reappraisal and resilience in the process of physical activity affecting university students' well-being is significant, with the chain-mediating effect value of 0.062.

CONCLUSION

Promoting university students' participation in physical activity not only directly enhances university students' subjective well-being but also indirectly improves university students' subjective well-being through cognitive reappraisal and resilience.

Clustered health risk behaviors with comorbid symptoms of anxiety and depression in young adults: Moderating role of inflammatory cytokines

BACKGROUND

People with multiple health risk behaviors (HRBs) are at higher risk for psychological problems, and vice versa. However, the mechanisms underlying this association remain unknown.

METHOD

We collected questionnaire and blood sample data from 2 universities in Anhui and Jiangxi Provinces. Demographic information, HRBs and blood samples were collected at baseline. Depression/anxiety symptoms were collected using questionnaires at follow-up. Latent class analysis was used to explore clustered HRBs pattern, and logistic regression analysis was used to examine the association between clustered HRBs quantity, pattern and anxiety-depression symptoms comorbidity. The Mplus software was used to analyze the moderating effects of inflammatory cytokines.

RESULTS

Compared to the HRB low-risk group, the substance dependence group (OR: 1.89, 95%CI: 1.11-3.21) and sedentary group (OR: 2.98, 95%CI: 1.48-6.02) had a higher risk of anxiety-depression comorbid symptoms. Compared to participants with no clustered HRBs, participants with 2 HRBs (OR: 2.16 95%CI: 1.17-4.00) and >3 HRBs (OR: 3.55, 95%CI: 1.68-7.48) were more likely to suffer from comorbid symptoms of anxiety and depression. Moreover, IL-6, IL-1β, IL-10 had negative moderating effects between clustered HRBs pattern and comorbid symptoms of anxiety and depression.

LIMITATIONS

Recall bias may exist for anxiety / depression symptoms, and cannot exclude unmeasured confounders or the effect of residual confounding.

CONCLUSIONS

This study finds clustered HRBs have a significant impact on mental health among young adults, and inflammatory cytokine evidence supports a negative moderating effect on the relationship. Interventions that decrease clustered HRBs may support mental health development in adolescence.

Exercise as the sum of our choices between behavioral alternatives: The Decisional Preferences in Exercising (DPEX) test

Exercising can be theorized as the result of choosing one behavior over alternative behaviors. The Decisional Preferences in Exercising (DPEX) test is a computerized, easy-to-use, publicly available (open source Python code: https://osf.io/ahbjr/) and highly adaptive research tool based on this rationale. In the DPEX, participants are asked to choose between two images by pressing a key on the computer keyboard, one showing a physical exercise and the other showing a non-exercise behavioral alternative in a series of trials. Combinations are randomly assembled from two definable pools of stimuli trial-per-trial. The test can be scored either based on a crossed random effects model (facilitating the use of different stimulus material in different studies without compromising the comparability of test scores) or with a simple proportion score. Data from diverse study samples (N = 451) showed strong correlations of DPEX scores with past and future exercise behavior (r = 0.42 and 0.47 respectively) as well as with affective experiences with exercise (e.g., 'pleasure-displeasure': r = 0.47). DPEX test scores discriminated between exercisers and non-exercisers according to receiver operating curve (ROC) analysis. The DPEX may be used to examine research questions derived from dual process theories, the effects of psychological states on behavioral choices can be tested, or the effects of behavior change interventions can be evaluated. The DPEX helps to avoid common method bias in the assessment of exercise behavior, for example, when psychological variables are measured with questionnaires.

The bidirectional association of nonalcoholic fatty liver disease with depression, bipolar disorder, and schizophrenia

Nonalcoholic fatty liver disease (NAFLD) is a complex metabolic-inflammatory disease associated with poor outcomes and decreased quality of life. NAFLD is overrepresented in patients with psychiatric disorders like depression, bipolar disorder, and schizophrenia; however, a comprehensive review on NAFLD and psychiatric disorders remains to be delineated. This review endeavors to investigate the association of NAFLD with psychiatric disorders, including shared pathogenesis and future clinical derivatives. Extant literature suggests that patients with psychiatric disorders (in particular, mood disorders) are more susceptible to the development of NAFLD due to multiple reasons, including but not limited to hypothalamic-pituitary-adrenal axis dysregulation, metabolic syndrome, and chronic perceived stress. Moreover, the clinical manifestations of mood disorders (e.g., anhedonia, psychomotor retardation, lifestyle modification, etc.), and potentially long-term treatment with weight-gaining agents, differentially affect these patients, making them more prone to NAFLD. Considering the increased morbidity associated with both mood disorders and NAFLD, our review recommends regular screenings for NAFLD in select patients with mood disorders exhibiting signs of increased risk (i.e., obesity, metabolic syndrome, diabetes, or family history of NAFLD) for better diagnosis and holistic care of both potentially interrelated conditions.

The Relationship Between Psychological Distress and Physical Activity Is Non-linear and Differs by Domain: a Cross-Sectional Study

BACKGROUND

There is increasing evidence for the relationship between physical activity (PA), sedentary behaviour and mental health. Limited data exists on sex-specific associations. We aimed to identify associations between PA dose and domain and television time with psychological distress, including sex-stratified models.

METHODS

A total of 22,176 adults from the Melbourne Collaborative Cohort Study follow-up 2 cohort (2003-2007) participated in this cross-sectional study. Occupational, household, transport, leisure PA, hours watching television and psychological distress were assessed. Restricted cubic splines were used to examine the relationships between PA domains, television viewing time and psychological distress.

RESULTS

The relationships between PA and psychological distress were non-linear (p < 0.05) and differed by PA domain. There were dose-dependent, inverse associations between distress with transport (B[95% CI] = -0.39[-0.49, -0.30]) and leisure PA (B[95% CI] = -0.35[-0.46, -0.25]). The effect estimates for transport and leisure PA with distress were larger for women. For household domain, a U-shaped curve with an elongated tail was seen. Median PA was associated with lower distress compared with lower quantities (B[95% CI] = -0.12[-0.22, -0.03]); however, this association was not evident with increasing household PA. There were no clear associations between occupational PA and distress. Higher television viewing was associated with higher distress (B[95% CI] = 0.16[0.02, 0.30]).

CONCLUSIONS

Increasing PA and reducing television viewing may contribute to reduced psychological distress, particularly in women. Future interventions should incorporate leisure and transport PA and decrease television viewing to assess the impact on mental health.

Association between engagement in cultural activities and use of general practitioner consultations: 7-year follow-up of adults from the HUNT study, Norway

OBJECTIVE

Assess whether engagement in a range of cultural activities, both 'passive' and 'active' (ie, receptive and creative) participation, is associated with later demand for general practitioner (GP) consultations.

DESIGN

Longitudinal prospective cohort study.

SETTING

Data from the population-based the third Survey of Trøndelag Health Study (2006-2008) in Norway was linked to an administrative register including service information from all GP offices nationwide.

PARTICIPANTS

This study included 17 396 (54.6%) women and 14 451 (45.4%) men aged 30-79 years.

MAIN OUTCOME MEASURES

Multilevel negative binomial regression models assessed the relationship between cultural engagement and GP consultations, and reported as rate ratios.

RESULTS

A mean of 3.57 GP visits per patient was recorded during the 7 years of follow-up. Participation in creative activities and a combination of both receptive and creative activities was associated with lower number of GP consultation. Gender-specific analyses suggest that these effects were attributable to men. The rate ratio of GP consultations among men taking part in creative activities less than once, twice and more than twice (<9 times) per week is 0.90, 0.89 and 0.87 times lower, respectively, compared with non-participants. Whereas weekly frequency of receptive and creative activity engagement showed a 0.92, 0.87 and 0.83 times lower rate ratio among engaged men. The variety of activities shows a similar pattern and participation in creative activities lowers the rate ratio among men. Engagement in a wide range/variety of activities, compared with non-engagement, was associated with lower numbers of GP consultations in men, but not women.

CONCLUSIONS

Engagement in creative or combined receptive and creative cultural activities was associated with lower numbers of GP consultations among men. Thus, facilitating and promoting a culturally engaged lifestyle, particularly in men, may affect primary healthcare use. However, this study design gives no evidence of a causal relationship between cultural engagement and use of GP consultations.

Association Between Wearable Device Use and Levels of Physical Activity Among Older Adults in the US: Evidence From the 2019-2020 Health Information National Trends Survey

Objective To examine the relationship between electronic wearable device (WD) use and physical activity (PA) levels among older adults in the US. Methods Data were pooled from 3310 older adults from the 2019 and 2020 Health Information National Trends Survey. The explanatory variable was WD use, and the outcomes were weekly PA levels, resistance training, and sedentary time. Logistic regression was conducted to investigate the association between WD use and the reported outcome variables. Separate logistic models were also fitted to explore the relationship between WD use and physical activity outcomes among a subgroup of older adults with chronic conditions. Results A total of 14.4% of older adults reported WD use. Older adults who use WD were more likely to meet national guidelines for weekly levels of PA (odds ratio (OR) 1.60, 95% confidence intervals (CI) (1.10, 2.32); p = 0.015) and resistance strength training (OR 1.54, 95% CI (1.14, 2.09); p = 0.005) when compared with their counterparts not using WD. After restricting the analysis to those with chronic conditions only, WD use was only associated with a higher level of weekly strength training (OR 1.68, 95% CI 1.19, 2.38; p = 0.004). Conclusion  WD use may be associated with increased physical activity among older adults, including those with chronic health conditions. Further studies are needed to examine the factors influencing the adoption and sustained use of WD in older adults.

Effectiveness of physical activity in managing co-morbid depression in adults with type 2 diabetes mellitus: A systematic review and meta-analysis

BACKGROUND

Physical activity may be effective in alleviating depressive symptoms and improving glycaemic control; however, evidence to guide practice is limited. The current review was conducted to assess the effects of physical activity on depression and glycaemic control in people with type 2 diabetes mellitus.

METHODS

Randomized controlled clinical trials, from the earliest record to October 2021, which recruited adults with the diagnosis of type 2 diabetes mellitus and compared physical activity with no interventions or usual care for the management of depression were included. The outcomes were change in depression severity and glycaemic control.

RESULTS

In 17 trials, including 1362 participants, physical activity was effective in reducing the severity of depressive symptoms (SMD = -057; 95%CI = -0.80, -0.34). However, physical activity did not have a significant effect in improving markers of glycaemic control (SMD = -0.18; 95%CI = -0.46, 0.10).

LIMITATIONS

There was substantial heterogeneity in the included studies. Furthermore, risk of bias assessment showed that most of the included studies were of low quality.

CONCLUSIONS

Physical activity can effectively reduce the severity of depressive symptoms, nonetheless, it appears that physical activity is not significantly effective in improving glycaemic control in adults who have both type 2 diabetes mellitus and depressive symptoms. The latter finding is surprising, however, given the limited evidence on which this is based, future research on the effectiveness of physical activity for depression in this population should include high quality trials with glycaemic control as an outcome.

Sociocultural predictors of obligatory exercise in young men: A Polish-Chinese comparison

BACKGROUND

Obligatory exercise has been shown to have negative physical and mental effects on exercisers and is more prevalent among young people. However, there is limited research on obligatory exercise among young men. Social comparison theory offers a novel perspective to explore the relationship between sociocultural factors and obligatory exercise among young men, which offers an opportunity to understand potential factors contributing to obligatory exercise among young men across different cultures.

METHOD

We recruited a purposive sample of young people aged 18-30 from Poland (n=79) and China (n=194). Participants completed self-report measures including the Sociocultural Attitudes Toward Appearance Questionnaire3, Inventory of Physical Activity Objectives, and Obligatory Exercise Questionnaire. In the data analysis stage, we examined the strength of the relationships between the independent variables and the dependent variable through multiple regression analysis, and tested the role of the mediating variables.

RESULTS

The main analyses revealed that Internalization-Athlete was a common direct predictor of obligatory exercise for both Polish and Chinese young men; that there were direct sociocultural predictors of obligatory exercise that were only used in relation to Polish or Chinese young men; and that social adaptation goals for motivation for physical activity mediated the development of obligatory exercise for Polish and Chinese young men, and that there were cross-cultural differences.

CONCLUSION

Attention should be paid to their attitudes towards the idea of a muscular and athletic body and socially adapted physical activity motivations when understanding young men's obligatory exercise, while also considering cross-cultural differences.

The Mediating Role of Eating Attitudes in Sociocultural Attitudes toward the Body in Predicting Obligatory Exercise among Young People: A Polish and Chinese Comparison

The main aims of this study were to determine which sociocultural predictors of obligatory exercise are universal for young men or women and which are specific to particular cultural conditions (Polish or Chinese culture) and to examine the mediating role of eating attitudes. A cross-sectional study was conducted among Poles (n = 259) and Chinese (n = 208) aged 18 to 30. Descriptive and comparative statistics, Spearman's rho, and multiple regression analysis were used. The main analyses showed that Internalization-Athlete was a common positive direct predictor of obligatory exercise among young Polish and Chinese women; Information and Internalization-Athlete were only specific direct positive predictors of obligatory exercise in young Chinese men; some variables in eating attitudes mediated the development of obligatory exercise in young Polish and Chinese men and women and indicated that there were cross-cultural differences. In understanding obligatory exercise among young people, attention should be paid to their sociocultural attitudes toward the body and eating, and cultural and gender differences need to be considered.

Public Health Residents' Anonymous Survey in Italy (PHRASI): Study Protocol for a Cross-Sectional Study for a Multidimensional Assessment of Mental Health and Its Determinants

The COVID-19 pandemic has evolved into a severe psychosocial crisis affecting patients, their relatives, friends, and healthcare professionals. In Italy, public health residents (PHRs) remain essential to the national response to the pandemic. To assess their mental sphere, the "Public Mental Health" working group of the medical residents' Assembly of the Italian Society of Hygiene and Preventive Medicine has designed the Public Health Residents' Anonymous Survey in Italy (PHRASI). This is a nation-wide cross-sectional study based on an 88-item self-administered voluntary survey that evaluates how sociodemographic variables are associated with mental issues, including wellness, eating disorders, sleeplessness, alcohol misuse, depression, and anxiety. Data will be gathered by disseminating a Google Forms link across the Assembly network of medical residents. All PHRs enrolled in a four-year program in one of the Italian postgraduate schools of public health will be qualified as participants. PHRASI aims to draw a comprehensive and detailed picture of the mental health state of Italian PHRs. PHRs are a significant group of healthcare professionals that may serve as a future benchmark for developing and enacting regulations intended to support the mental health of healthcare professionals.

Perspectives of the Saudi medical students toward the impact of lockdowns on their physical activity level and lifestyle during the COVID-19 pandemic

Background

Physical activity (PA) level is affected by various factors in university students. Due to the pandemic of COVID-19, the Saudi Ministry of Education announced the closure of schools and universities as a preventive measure. This cross-sectional study aimed to evaluate the impact of the COVID-19 pandemic lockdown on PA levels and other lifestyle aspects among the Saudi medical students and to explore their perspectives toward it.

Methods

Three hundred ninety-six medical students have completed the survey, which consisted of three sections: (1) participant's demographic data; (2) five statements about the PA and the lockdown; and (3) the International PA Questionnaire-Short Form (IPAQ-SF).

Results

About 63.9% of the participants were female, and 60.4% were of normal weight. Approximately 80% of participants were classified as inactive. Regarding the perspective of the students, 52.8% reported that they were not exercising regularly in the gym before the lockdown, and 46.9% reported that the lockdown and transition to online learning affected their compliance with exercise. During the lockdown and shift to online learning, the majority of participants experienced decreased PA levels, 42.4% experienced weight gain, and 53.6% reported a negative impact on their psychological status.

Conclusion

Generally, the results of this study showed that the COVID-19 had a negative influence on the PA level, as well as other lifestyle aspects (e.g., gaining weight) and psychological status of medical students. This study highlights aspects where universities and institutions delivering medical education can use resources to improve students' well-being during pandemics.

Device-measured physical activity and incident affective disorders

BACKGROUND

Studies on physical activity (PA) and mental health are largely limited to self-reported PA. This study aims to use prospective cohort data to investigate the association between device-measured PA and affective disorders.

METHODS

A total of 37,327 participants from UK Biobank who had not had any prior affective disorder diagnoses were included in this prospective cohort study. Wrist-worn accelerometers were used to measure total, light (LPA), moderate (MPA), and vigorous (VPA) PA. Associations between PA domains and affective disorders were analysed using penalised splines in Cox proportional hazard models. Analyses were adjusted for other intensity-specific PA and sociodemographic and lifestyle factors. Sensitivity analyses were conducted adjusting for body mass index and longstanding illnesses as well as excluding events in the first 2 years of follow-up. Preventable fractions for the population were estimated for MPA and VPA.

RESULTS

Over a median follow-up of 6.8 years, 1262 (3.4%) individuals were diagnosed with affective disorders. Replacing 30 min of sedentary behaviour in a week with MPA (HR 0.95, 95% CI 0.94-0.97) or VPA (HR 0.91, 95% CI 0.85-0.98) was associated with lower risk of affective behaviours, up to 500 and 120 min of MPA and VPA. Assuming causality, 5.14% and 18.88% of affective disorders could have been prevented if MPA ≥150 min/week and VPA ≥75 min/week were achieved, respectively, across the study population.

CONCLUSIONS

Device-measured MPA and VPA were associated with lower risk of affective disorders. The potential mental health benefits of MPA continue to accrue above the current World Health Organization recommendation.

Healthcare professionals' perceptions and experiences of physiotherapy for people with mental illness: a protocol for a systematic review and meta-ethnography

INTRODUCTION

There is a high global prevalence of patients presenting with physical and mental health comorbidities. Physiotherapeutic interventions, such as exercise, can have positive benefits for physical and mental health. However, poor accessibility and negative experiences of healthcare services for those with mental illness (MI) have been consistently observed within literature with recent research identifying poor experiences of physiotherapeutic interactions and processes such as referrals and discharges. One way to help improve physiotherapy services for this population is to understand the personal experiences and perceptions of healthcare professionals (HCPs) toward physiotherapy for patients with MI. Qualitative-based evidence syntheses are suited to bring this data together with the aim of improving physiotherapy services for patients with MI. This review will systematically search and synthesise existing evidence around HCP experiences and perceptions of physiotherapy for people with MI.

METHODS AND ANALYSIS

A systematic search and seven-phase meta-ethnography will be undertaken. A comprehensive search of electronic databases (CINAHL plus, MEDLINE, Pubmed, Embase and Psycinfo) and search engines as well as grey literature (unpublished primary research such as theses) will be completed. Searches are planned to take place in July 2022. Eligibility criteria include: (a) qualitative data, (b) perceptions identified from HCP, including physiotherapists, assistants and HCP referring into physiotherapy, about physiotherapy for patients with MI and (c) are primary studies.

ETHICS AND DISSEMINATION

This work is exempt from requiring ethical approval due to review methodology with data accessed from published works. This systematic review is expected to provide insight into experiences and perceptions of HCP around benefits and barriers to accessing physiotherapy for patients with mental health illness. Findings will be used to inform further research and co-develop recommendations to overcome barriers and optimise facilitators to care for this population. Findings will be disseminated via peer-reviewed journal, conference presentations and to key stakeholder groups.

Association between Type and Intensity of Physical Activity and Depression

Background

Although numerous studies have indicated that lower levels of physical activity correlate with a higher risk of depression, an association between the type of physical activity and depression has not been identified in Korea. This study aimed to examine whether the type and intensity of physical activity are associated with depression in Korean adults.

Methods

This cross-sectional study used data from the Korea National Health and Nutrition Examination Survey (KNHANES). A total of 11,679 individuals were analyzed using multiple logistic regression analyses to identify any association between the type of physical activity and depressive disorders in the sample subjects.

Results

Measured weekly in units of energy expenditure, known as metabolic equivalents (METs), the amount of work-related physical activity was higher in individuals with depression according to the Patient Health Questionnaire- 9 than the participants without depression (386.7 vs. 206.7 MET-min/wk, P=0.01). Those diagnosed with depression tended to engage in less recreational activity per week (143.7 vs. 316.3 MET-min/wk, P<0.001) than those without depression. After controlling for covariates, the risk of depression among all participants was 1.012 times higher with a 100-unit increase in total work-related activity measured in METs (95% confidence interval [CI], 1.006–1.017; P<0.001) and 0.962 times lower with a 100-unit increase in total leisure activity measured in METs (95% CI, 0.937–0.987; P=0.003).

Conclusion

Different types of physical activity were shown to be differently associated with depressive disorders in Korean adults. This study might guide in reducing work-related physical activity and increasing leisure activity to prevent the occurrence of depression.

Association Between Physical Activity and Risk of Depression: A Systematic Review and Meta-analysis

Importance

Depression is the leading cause of mental health-related disease burden and may be reduced by physical activity, but the dose-response relationship between activity and depression is uncertain.

Objective

To systematically review and meta-analyze the dose-response association between physical activity and incident depression from published prospective studies of adults.

Data Sources

PubMed, SCOPUS, Web of Science, PsycINFO, and the reference lists of systematic reviews retrieved by a systematic search up to December 11, 2020, with no language limits. The date of the search was November 12, 2020.

Study Selection

We included prospective cohort studies reporting physical activity at 3 or more exposure levels and risk estimates for depression with 3000 or more adults and 3 years or longer of follow-up.

Data Extraction and Synthesis

Data extraction was completed independently by 2 extractors and cross-checked for errors. A 2-stage random-effects dose-response meta-analysis was used to synthesize data. Study-specific associations were estimated using generalized least-squares regression and the pooled association was estimated by combining the study-specific coefficients using restricted maximum likelihood.

Main Outcomes and Measures

The outcome of interest was depression, including (1) presence of major depressive disorder indicated by self-report of physician diagnosis, registry data, or diagnostic interviews and (2) elevated depressive symptoms established using validated cutoffs for a depressive screening instrument.

Results

Fifteen studies comprising 191 130 participants and 2 110 588 person-years were included. An inverse curvilinear dose-response association between physical activity and depression was observed, with steeper association gradients at lower activity volumes; heterogeneity was large and significant (I2 = 74%; P < .001). Relative to adults not reporting any activity, those accumulating half the recommended volume of physical activity (4.4 marginal metabolic equivalent task hours per week [mMET-h/wk]) had 18% (95% CI, 13%-23%) lower risk of depression. Adults accumulating the recommended volume of 8.8 mMET hours per week had 25% (95% CI, 18%-32%) lower risk with diminishing potential benefits and higher uncertainty observed beyond that exposure level. There were diminishing additional potential benefits and greater uncertainty at higher volumes of physical activity. Based on an estimate of exposure prevalences among included cohorts, if less active adults had achieved the current physical activity recommendations, 11.5% (95% CI, 7.7%-15.4%) of depression cases could have been prevented.

Conclusions and Relevance

This systematic review and meta-analysis of associations between physical activity and depression suggests significant mental health benefits from being physically active, even at levels below the public health recommendations. Health practitioners should therefore encourage any increase in physical activity to improve mental health.

Changes Among Mexican Adults in Physical Activity and Screen Time During the COVID-19 Lockdown Period and Association With Symptoms of Depression, Anxiety, and Stress, May 29-July 31, 2020

Introduction

We examined the association between changes in physical activity and leisure screen time and mental health outcomes during the early stages of the recommended COVID-19 stay-at-home period in a national sample of Mexican adults aged 18 years or older.

Methods

A cross-sectional online survey conducted from May 29 through July 31, 2020, among 1,148 participants, reported time spent in physical activity and leisure screen time during a typical week before (retrospectively) and a week during the COVID-19 stay-at-home period. Mental health outcomes during this period were measured with the Depression, Anxiety and Stress Scale (DASS-21). Linear regression models were used to estimate the associations between changes in physical activity and leisure screen time and mental health outcomes by socioeconomic status (SES), adjusting for potential confounders.

Results

Compared with maintaining high levels of physical activity or increasing them, decreasing physical activity was associated with higher stress scores overall, and among people of high SES, with higher scores for DASS-21, depression, and anxiety. Among participants of low and medium SES only, increasing screen time was associated with higher DASS-21, depression, anxiety, and stress scores compared with maintaining low or decreasing leisure screen time.

Conclusion

Results highlight the potential protective effect of physical activity and limited leisure screen time on mental health in the context of COVID-19 stay-at-home restrictions.

Physical Activity Levels of a Multi-Ethnic Population of Young Men Living in Saudi Arabia and Factors Associated With Physical Inactivity

Objective

Regular physical activity is essential for lifelong optimal health. Contrarily, physical inactivity is linked with risk for many chronic diseases. This study was conducted to evaluate the physical activity levels and factors associated with physical inactivity among a multi-ethnic population of young men living in Saudi Arabia.

Methods

This is a cross-sectional study involving 3,600 young men (20–35 years) living in Riyadh, Saudi Arabia. Sociodemographic and physical activity data were collected from subjects by face-to-face interviews. Physical activity characteristics were evaluated by using the Global Physical Activity Questionnaire. Weight and height were measured following standardized methods, then body mass index was calculated.

Results

Physical inactivity was reported among 24.9% of study subjects. The lowest and highest rates of physical inactivity were reported among subjects from the Philippines (14.0%) and Saudi Arabia (41.5%), respectively. There is a high variation in daily minutes spent on physical activities related to work, transport, recreation, vigorous and moderate-intensity physical activities and sedentary behaviors among study participants based on their nationalities. Nationality, increasing age, longer residency period in Saudi Arabia, living within a family household, having a high education level, earning a high monthly income, and increasing body mass index were significantly associated with a higher risk of physical inactivity among the study participants.

Conclusion

Physical inactivity prevalence is relatively high among a multi-ethnic population of young men living in Saudi Arabia. The findings confirmed notable disparities in the physical activity characteristics among participants from different countries living in Saudi Arabia.

Physical Activity Levels of a Multi-Ethnic Population of Middle-Aged Men Living in Saudi Arabia and Factors Associated With Physical Inactivity

Objectives: This study investigated physical activity levels and factors related to physical inactivity in a multi-ethnic population of middle-aged men living in Saudi Arabia.

Methods: This is a cross-sectional study in which 1,800 men aged 36–59 years old from Riyadh, Saudi Arabia participated. The Global Physical Activity Questionnaire was used to assess the physical activity levels. The weight and height were measured and used to calculate the body mass index.

Results: Among all participants, 35.3% are physically inactive. The participants with the lowest and highest rates of physical inactivity were from the Philippines (15.5%) and Saudi Arabia (57.8%), respectively. This study suggests that the risk of physical inactivity among participants is positively or negatively affected by various factors, including nationality, residency period in Saudi Arabia, living with/without family, education level, monthly income, and body mass index.

Conclusion: The prevalence of physical inactivity is relatively high among middle-aged men in Saudi Arabia. The findings revealed significant differences in physical activity levels based on nationality, other sociodemographic variables and body weight status.

Physical activity attenuates negative effects of short-term exposure to ambient air pollution on cognitive function

BACKGROUND

As physical activity benefits brain health whereas air pollution damages it, the cognitive response to these exposures may interact.

PURPOSE

This study aimed to assess the short-term joint effect of physical activity and air pollution on cognitive function in a panel of healthy young adults.

METHODS

We followed ninety healthy subjects aged around 22 years from September 2020 to June 2021 and measured their personal exposure to fine particulate matter (PM_2.5) (μg/m³) and daily accelerometer-based moderate-to-vigorous physical activity (MVPA) (min/day) in 4 one-week-long sessions over the study period. At the end of each measurement session, we assessed executive function using Stroop color-word test and collected resting-state electroencephalogram (EEG) signals.

RESULTS

We found short-term PM_2.5 exposure damaged executive function (β_PM25 = 0.0064, p = 0.039) but physical activity could counterbalance it (β_MVPA = -0.0047, p = 0.048), whereby beta-3 wave played as a potential mediating role. MVPA-induced improvement on executive function was larger in polluted air (β_MVPA = -0.010, p = 0.035) than that in clean air (β_MVPA = -0.003, p = 0.45). To offset the negative effect of air pollution on cognitive function, individuals should do extra 13.6 min MVPA every day for every 10 μg/m³ increase in daily PM_2.5.

CONCLUSION

This study implies that physical activity could be used as a preventive approach to compensate the cognitive damages of air pollution.

Prevalence of Physical Activity Among Healthcare Students in King Saud University, Riyadh, Saudi Arabia. An Observational Study

Background and Objective

Physical inactivity is 1 of the most important cardiovascular risk factors causing higher morbidity and mortality rate worldwide. Thus, the promotion of physical activity (PA) is 1 of the fundamental pillars in the primary prevention of heart disease. Therefore, this study aimed to assess the prevalence of Physical Activity among healthcare Students in the Riyadh region, Saudi Arabia.

Methods

An observational, descriptive, cross-sectional study using paper-based printed questionnaires was conducted among Emergency medical students (EMS) from the Prince Sultan College for Emergency Medical Services King Saud University. To evaluate the physical activity, Global Physical Activity Questionnaire (16-items) developed by the World health organization was used. The questionnaires talk about activity at work (6 items), travel to and from places (3-items), recreational activities (6- items), and sedentary behavior (1-item). Both binary answers (Yes\No) and continuous scales were used to collect the data. Data were descriptively analyzed using a statistical package for social science version 26 (SPSS).

Results

The prevalence of PA among students was 69.9% (n = 123). The most common type of physical activity was walking, accounted for 51.7% (n = 91), followed by Gym/bodybuilding 25% (n = 44), running 24.4% (n = 43). A total of 7.16 mean hours (SD = 11.23) were spent by students doing vigorous-intensity activities on a typical day, while 4.93(SD = 8.84) of mean hours were spent on moderate-intensity activities. Additionally, more than half of the students 55.7% (n = 98) performed vigorous-intensity sports, fitness, or recreational activities that cause large increases in breathing or heart rate (for at least 10 minutes continuously). The mean time spent by the students in this study performing vigorous-intensity sports, and fitness activity were 4.60(SD = 10.22) mean hours per day. The sedentary behavior, like constant sitting, was reported to be 7.33 (SD = 4.24) mean hours per day.

Conclusion

In conclusion, about 3 in ten EMS students are physically inactive, which could be due to study-related actions. Future research among undergraduates should focus on approaches to increase PA is needed.

Eight-week high-intensity interval training is associated with improved sleep quality and cardiorespiratory fitness in patients with depressive disorders

PURPOSE

This study aimed to examine the effect of high-intensity interval training (HIIT) on both sleep and cardiorespiratory fitness in patients with depression.

METHODS

Using a single pre- and post-test study design with no control group, 82 patients diagnosed with depressive disorders underwent HIIT comprising a total of 24 15-min sessions, three times per week for 8 weeks. Depressive symptoms, sleep quality, and cardiorespiratory fitness were evaluated using the Beck depression inventory-II, the Pittsburgh sleep quality index (PSQI), and cardiopulmonary exercise testing (CPET) in the form of maximum oxygen uptake (VO₂ max), respectively.

RESULTS

All 82 patients completed the intervention. HIIT training was associated with significant improvements in BDI-II score (diff =  - 1.57 [95% CI - 2.40 to - 0.73], P = 0.001), PSQI score (diff =  - 1.20 [95% CI - 2.10 to - 0.32], P = 0.008), and CPET VO₂ max (diff = 0.95 [95% CI 0.62-1.28], P = 0.001). Effect size calculations revealed that the greatest improvement occurred in CPET VO₂ max (Cohen's d = 0.64) and that improvements in the BDI-II and PSQI scores were somewhat smaller in magnitude (Cohen's d =  - 0.41 and - 0.30, respectively). Sleep quality improvements were observed in sleep latency, habitual sleep efficiency, and the use of sleep-promoting medications (Cohen's d = 0.18, 0.19, and 0.25, respectively). Change in cardiorespiratory fitness successfully predicted change in sleep quality but not in depressive symptoms. Adverse effects were limited to minor injuries which did not interfere with completion of training.

CONCLUSIONS

HIIT training delivered over 8 weeks was associated with improvements in depression symptoms, sleep quality, and cardiorespiratory fitness in patients with depressive disorders.

Effects of the COVID-19 pandemic and lockdown in Spain: comparison between community controls and patients with a psychiatric disorder. Preliminary results from the BRIS-MHC STUDY

BACKGROUND

The aim of this study was to evaluate potential differences about the effects of the COVID-19 pandemic and lockdown between community controls (CC) and patients with a mental illness (MI) in a Spanish population during the state of emergency.

METHODS

Individuals with a psychiatric condition and the general population were invited to complete an anonymous online survey. Bivariate analyses were used to compare them in a broad range of measures: sociodemographic, clinical variables, behavioral changes related to the lockdown and coping strategies to face it. Two groups of different psychiatric disorders were compared: depression or anxiety disorders (D+A) versus bipolar disorder and schizophrenia related disorders (BD+SCZ).

RESULTS

413 CC and 206 MI were included in the study. CC reported to use more adaptive coping strategies as following a routine, talking to friends/relatives, practicing physical exercise and maintaining a balanced diet. MI reported significantly more anxiety and depression symptoms during the lockdown when compared to CC. Gaining weight, sleep changes, and tobacco consumption were more prevalent in the MI group. The D+A group showed significantly more psychological distress and negative expectations about the future, suffered more sleep disturbances when compared to BD+SCZ, whilst reported to practice more exercise.

LIMITATIONS

psychiatric disorders were self-reported.

CONCLUSIONS

Imposed restrictions and uncertainty during confinement had a higher psychological impact in individuals with a psychiatric illness, with less healthy behavior strategies to face the situation. Developing interventions to mitigate negative mental health outcomes among this vulnerable population will be essential in the coming months.

Physical exercise, mental health problems, and suicide attempts in university students

BACKGROUND

Physical inactivity and mental health problems are both major public health concerns worldwide. Although several studies have demonstrated the health benefits of regular physical exercise, few epidemiological studies have investigated the nature of the association between different aspects of physical exercise and mental health, and little is known regarding the possible link to suicidality.

STUDY AIM

To examine the association between frequency, intensity, and duration of physical exercise and mental health problems, and to explore whether low levels of physical activity is related to self-harm and suicide attempts among college and university students.

METHODS

We employed data from the SHoT2018-study, a national health survey for higher education in Norway, in which 50,054 students aged 18-35 years participated. Physical exercise was assessed with three questions (frequency, intensity, and duration). Mental health problems were assessed with both a screening tool assessing psychological distress (Hopkins Symptom Checklist-25; HSCL-25) and self-reported depressive disorder (using a pre-defined list of conditions). Suicide attempts and self-harm were assessed with two items from the Adult Psychiatric Morbidity Survey.

RESULTS

Physical exercise was negatively associated with all measures of mental health problems and suicidality in a dose-response manner. The strongest effect-sizes were observed for frequency of physical exercise. Women with low levels of physical activity had a near three-fold increased odds of both scoring high on the HSCL-25, and self-reported depression, compared to women exercising almost every day. Even stronger effect-sizes were observed for men (ORs ranging from 3.5 to 4.8). Also, physical exercise duration and intensity were significantly associated with mental health problems, but with generally smaller ORs. Similarly, graded associations were also observed when examining the link to self-harm and suicide attempts (ORs ranging from 1.9 to 2.5).

CONCLUSION

Given the demonstrated dose-response association between inactivity and both poor mental health, self-harm, and suicidal attempt, there is a need to facilitate college students to become more physically active. This is a shared responsibility that resides both on a political level and on the post-secondary institutions. The cross-sectional nature of the study means that one should be careful to draw firm conclusion about the direction of causality.

Muscle-strengthening exercise and prevalent hypertension among 1.5 million adults: a little is better than none

BACKGROUND

Clinical evidence suggests that muscle-strengthening exercise (using weight machines/body weight exercises) may be an important antihypertensive lifestyle therapy. However, epidemiological research on the association between muscle-strengthening exercise and hypertension is limited. We conducted the first population-level study describing the associations between muscle-strengthening exercise and prevalent hypertension among a large sample of US adults.

METHODS

In this cross-sectional study, data were pooled from four US health surveillance surveys (2011-2017) (n = 1 539  309, aged ≥18 years). Muscle-strengthening exercise frequency and self-reported clinically diagnosed hypertension (n = 431 313; 28%) were assessed using the same items across each survey. Generalized linear models using Poisson regression with robust error variance were used to calculate the prevalence ratios of hypertension (outcome variable) across muscle-strengthening exercise [exposure variables: 0 (reference); 1 to ≥7 times/week), adjusting for potential cofounders.

RESULTS

Compared with those doing none, the adjusted prevalence ratios for hypertension were 0.67 (95% CI: 0.66-0.68), 0.67 (95% CI: 0.67-0.68), 0.70 (95% CI: 0.69-0.70), 0.61 (95% CI: 0.60-0.63), 0.62 (95% CI: 0.61-0.64), 0.60 (95% CI: 0.58-0.62) and 0.83 (95% CI: 0.82-0.84) among the groups engaging in muscle-strengthening exercise one, two, three, four, five, six, and at least seven times/week, respectively. Associations remained after stratification for sociodemographic factors (age, sex), lifestyle characteristics (aerobic exercise, BMI, self-rated health, smoking, alcohol) and comorbidities (e.g. arthritis, diabetes, depression).

CONCLUSION

Among over 1.5 million adults, compared with those doing none, any weekly frequency in muscle-strengthening exercise was associated with a lower prevalence of hypertension. Longitudinal studies and large-scale muscle-strengthening exercise interventions with population representative samples are needed to confirm these preliminary cross-sectional observations.

Exploring the Use of Meditation as a Valuable Tool to Counteract Sedentariness

Some forms of meditation have been recently proposed as effective tools to facilitate the handling of undesired thoughts and reappraisal of negative emotions that commonly arise during exercise-related situations. The effects of meditation-based interventions on psychological responses could also be used as a means by which to increase exercise adherence and counteract the detrimental consequences of sedentariness. In the present article, we briefly describe the effects of meditation on physical activity and related factors. We also propose a theoretical model as a means by which to further understanding of the effects of meditation on psychological, psychophysical, and psychophysiological responses during exercise. The results of very recent studies in the realms of cognitive and affective psychology are promising. The putative psychological mechanisms underlying the effects of meditation on exercise appear to be associated with the interpretation of interoceptive and exteroceptive sensory signals. This is primarily due to the fact that meditation influences the cerebral processing of physical sensations, emotions, and thoughts. In such instances, the bodily and perceptual responses that are commonly reported during exercise might be assuaged during the practice of meditation. It also appears that conscious presence and self-compassion function as an emotional backdrop against which more complex behaviors can be forged. In such instances, re-engagement to physical activity programs can be more effectively achieved through the implementation of holistic methods to treat the body and mind. The comments provided in the present paper might have very important implications for exercise adherence and the treatment of hypokinetic diseases.

Joint and dose-dependent associations between aerobic and muscle-strengthening activity with depression: A cross-sectional study of 1.48 million adults between 2011 and 2017

BACKGROUND

Research has shown that regular physical activity is key for the prevention and/or treatment of depression. However, epidemiological studies describing the associations between different physical activity modes (i.e., aerobic vs. muscle-strengthening exercise) with depression are limited.

METHODS

Cross-sectional analyses were conducted on pooled data from four U.S. health surveillance surveys (2011-2017). Validated survey items assessed self-reported moderate-to-vigorous-intensity physical activity (MVPA) and muscle-strengthening activity (MSA). Twenty groups were created, ranging from (a) "inactive" (0 MVPA min/week & MSA 0 times/week) to (xx) "most active" (≥300 MVPA min/week & MSA ≥4 times/week). Poisson regression with a robust error variance was used to assess prevalence ratios (PRs) of self-reported clinically diagnosed depression (outcome variable) across physical activity groups (exposure variables).

RESULTS

The sample contained 1,477,981 adults (≥18 years), of which 286,325 (18.0%) had depression. Compared to the reference group (i.e., no MVPA and no MSA), almost all physical activity combinations were associated with lower depression prevalence. Lowest prevalence of depression was shown for those combining sufficient MVPA-MSA (MVPA ≧300 min/week and MSA ≥2 times/week; adjusted prevalence ratio range: 0.54-0.63). All associations remained after stratification and/or adjustment for sociodemographic (age, sex, income, education), lifestyle characteristics (body mass index, self-rated health, smoking, alcohol), comorbidities (e.g., arthritis, diabetes, hypertension), and year of survey.

CONCLUSIONS

A physical activity routine that includes both aerobic and MSA is likely to be optimal for the prevention of depression. Public health approaches targeting depression should endorse joint aerobic and MSA as key lifestyle modification strategy.

Correlation of physical activity with stress, depression and anxiety in female students

Background/Aim: The period of beginning of studies is a stressful period of life in which students are expected to develop skills and abilities with which they will be able to take on the most important roles in all areas of social activity. Physical activity (PA) triggers and remodels mental health. The aim of the study was to determine the correlation between PA and stress, anxiety and depression in female students. Methods: Epidemiological observational study was performed and included a representative sample of 408 healthy female students aged 19 to 22 years. Questionnaires were used and anthropometric measurement of weight and body mass index (BMI) calculation was performed. Used questionnaires were: a socio-demographic questionnaire, standardised tests: DASS-21 test (short version) for mental health assessment and International Physical Activity Questionnaire-IPAQ test (long version). Results: Mean age of female students was 20.5 ± 0.72 years, average height 168.65 ± 6.01 cm, body weight 63.09 ± 9.9 kg, and BMI 22.1 ± 3.2. A significant negative correlation was found between high PA and anxiety (r =-0.160, p = 0.001), PA and depression (r =-0.118, p = 0.01), while the category of stress had a low correlation with PA. Conclusion: This research shows that a high level of PA has no effect on stress but has an effect on reducing anxiety and depression. Carefully planned physical activities can affect the emotional status of young female students.
