Effectiveness of physical activity interventions for improving depression, anxiety and distress: an overview of systematic reviews

Mindfulness-based (non-contact) boxing therapy (MBBT) for depression and anxiety: A feasibility study

OBJECTIVES

Mindfulness-Based (non-contact) Boxing Therapy (MBBT) is a novel intervention designed to empower and promote self-agency through behavioral interventions, while reducing barriers to exercise for individuals with mental disorders. MBBT is an instructor-led, manualized, non-contact boxing group-exercise program (delivered in 90 min sessions, twice a week, over 10 weeks) that blends principles of mindfulness, meditation and group therapy. The current study tested the acceptability and feasibility of delivering MBBT to adults with major depressive disorder (MDD) or generalized anxiety disorder (GAD).

METHODS

Nine adult outpatients with MDD or GAD were recruited from a psychiatric outpatient clinic in Toronto, Canada in a 10-week feasibility trial of MBBT using a pre-post design. Feasibility was assessed through recruitment and retention rates, while acceptability was assessed through the CSQ-8, and self-questionnaires. Secondary clinical outcomes included the PHQ-9, GAD-7, K10, CGI, and MAAS. Trial registry: ISRCTN23023309.

RESULTS

Eight participants (5 female, 3 male) were included in the final analysis. Results indicated a high user retention (89%), attendance (84%), and satisfaction (98%). The study observed a statistically significant mean percent reduction in depression (54%), anxiety (51%) and distress (36%), alongside a mean percent increase in mindfulness (79%). Post intervention qualitative feedback from participants revealed themes of inclusivity and accessibility, cathartic release and control of emotions, improved self-esteem and confidence, self-agency, community, and trust in leadership.

CONCLUSIONS

Given the limitation of the study, MBBT appeared to be feasible and acceptable as an exercise/behavioural intervention. Further well-designed randomized clinical trials are warranted to confirm the clinical benefits of MBBT.

Associations of physical activity and mental health in pregnant women: A cross-sectional isotemporal substitution analysis

BACKGROUND

Prenatal mental health is an increasing public concern. At present, it has been shown that increasing physical activity (PA) is effective in promoting mental health of pregnant women. However, mental health may depend not only on the amount of time spent on a specific activity, but also on the intensity and type of the activity that it replaces. This study is aimed to explore the impact of replacing 60 min of one health behavior with another on the mental health of pregnant women.

METHODS

The cross-sectional study recruited 983 pregnant women from Chongqing, China between June and December 2021. The pregnant women self-reported their movement behaviors using the Pregnancy Physical Activity Questionnaire-Chinese version (PPAQ-C). Participants also completed three measures of mental health: Childbirth Attitudes Questionnaire (CAQ), 9-item Patient Health Questionnaire (PHQ-9) and the Positive affect sub-scale. An Isotemporal Substitution Model was used to evaluate mental health after replacing one movement behavior.

RESULTS

The analysis showed that replacing 60 min of sedentary behavior (SB) with moderate-to-vigorous intensity PA (MVPA) promoted positive emotions, and replacing SB with light intensity PA (LPA) reduced childbirth fear. Regarding PA types, replacing inactivity with household, occupational, or transport PA could reduce fear, and replacing inactivity, occupational, household or transport PA with sport PA could improve positive emotions and alleviate depression.

CONCLUSION

An active pregnancy lifestyle with higher levels of moderate-to-vigorous physical activity and light physical activity and less sedentary behavior time and other inactive states may improve mental health. Future health promotion for pregnant women should consider the flexibility of physical activity types and intensities.

Pre-operative impact of multimodal prehabilitation in gynecologic oncology patients

OBJECTIVE

Multimodal prehabilitation is a multi-disciplinary program that includes exercise, nutrition, and psychological intervention before surgery to improve pre-operative functional capacity. This study aims to assess the impact of a prehabilitation program on the pre-operative functional status of gynecologic oncology patients.

METHODS

This single-center, prospective observational study included all consecutive patients diagnosed with gynecologic cancer who were scheduled for surgery and enrolled in a structured prehabilitation program from January 2018 to May 2024. Only patients with both baseline and pre-operative evaluations were included. Functional status data were compared before (baseline) and after (pre-operative) the prehabilitation intervention. The primary outcome measured was functional capacity, as determined by the 6-minute walk test (6MWT). Secondary outcomes included hand grip strength, the Malnutrition Universal Screening Tool (MUST) score, and the Hospital Anxiety and Depression Scale score. The type of training and adherence were also evaluated.

RESULTS

A total of 77 patients underwent both baseline and pre-operative evaluation at the prehabilitation unit. The median duration of the program was 25.2 days (range; 9-63). Significant pre-operative improvements were observed in 6MWT (baseline: 435.7 m, standard deviation [SD] = 115.9 vs pre-operative: 455.7 m, SD = 118.9, p < .001), hand grip strength (baseline: 19.0 kg, SD = 5.5 vs pre-operative: 20.4 kg, SD = 5.9, p = .012), MUST score (baseline MUST ≥2 in 14.3% patients vs pre-operative 3.9%, p = .03), and Hospital Anxiety and Depression Scale score (baseline anxiety score: 7.4, SD = 4.3 vs pre-operative: 6.3, SD = 3.6, p < .001; and baseline depression score: 5.5, SD = 4.2 vs pre-operative: 4.3, SD = 3.6, p < .001). Among the different training programs, patients participating in supervised CrossFit training showed greater improvement in the 6MWT (33.4 m), compared to the hospital-supervised group (27.1 m), and the non-supervised home training group (14.0 m).

CONCLUSIONS

A structured multimodal prehabilitation program improves pre-operative functional capacity in gynecologic oncology patients, with the greatest improvements seen in those who participated in supervised high-intensity training, such as CrossFit.

Associations between physical activities and self-harm behaviour in depression across the genotype: findings from the UK biobank

BACKGROUND

Physical activities are widely implemented for non-pharmacological intervention to alleviate depressive symptoms. However, there is little evidence supporting their genotype-specific effectiveness in reducing the risk of self-harm in patients with depression.

AIMS

To assess the associations between physical activity and self-harm behaviour and determine the recommended level of physical activity across the genotypes.

METHOD

We developed the bidirectional analytical model to investigate the genotype-specific effectiveness on UK Biobank. After the genetic stratification of the depression phenotype cohort using hierarchical clustering, multivariable logistic regression models and Cox proportional hazards models were built to investigate the associations between physical activity and the risk of self-harm behaviour.

RESULTS

A total of 28 923 subjects with depression phenotypes were included in the study. In retrospective cohort analysis, the moderate and highly active groups were at lower risk of self-harm behaviour. In the followed prospective cohort analysis, light-intensity physical activity was associated with a lower risk of hospitalisations due to self-harm behaviour in one genetic cluster (adjusted hazard ratio, 0.28 [95% CI, 0.08-0.96]), which was distinguished by three genetic variants: rs1432639, rs4543289 and rs11209948. Compliance with the guideline-level moderate-to-vigorous physical activities was not significantly related to the risk of self-harm behaviour.

CONCLUSIONS

A genotype-specific dose of light-intensity physical activity reduces the risk of self-harm by around a fourth in depressive patients.

Impact of Internet Usage on Depression Among Older Adults: Comprehensive Study

BACKGROUND

Depression is a widespread mental health issue affecting older adults globally, with substantial implications for their well-being. Although digital interventions have proven effective in high-income countries, research on the potential of internet usage to alleviate depression among older adults in high-income countries remains limited.

OBJECTIVE

This study aimed to examine the impact of internet usage on depression among older adults in high-income countries by developing a comprehensive theoretical framework and testing key hypotheses.

METHODS

Using data from the China Health and Retirement Longitudinal Study (CHARLS), a 2-stage instrumental variable approach was applied to address endogeneity and estimate causal relationships between internet usage and depression.

RESULTS

The findings indicate that internet usage results in a 1.41% reduction in depression levels among older adults. This effect is mediated by four primary mechanisms: (1) enhanced social interaction, (2) increased physical activity, (3) improved intergenerational contact, and (4) expanded access to educational opportunities. A heterogeneity analysis revealed that these effects are more pronounced in urban areas, eastern regions, and regions with superior internet infrastructure.

CONCLUSIONS

Internet usage plays a crucial role in alleviating depression among older adults in high-income countries, with regional variations. The findings highlight the need for targeted policy interventions to improve internet access and digital literacy, which can mitigate depression and enhance the mental health of older adults.

Effects of exercise dose based on the ACSM recommendations on depression in hemodialysis patients: a systematic review and meta-analysis of randomized controlled trials

Objective

To explore the impact of various exercise doses on depressive symptoms among hemodialysis patients and offer valuable guidance for the selection of optimal exercise doses in clinical practice settings.

Methods

A comprehensive systematic review was conducted across four major databases, namely, PubMed, Embase, Web of Science, and Cochrane Library, covering the period from their inception until August 2024. Exercise interventions were classified based on adherence to American College of Sports Medicine (ACSM) recommendations, dividing studies into groups with high and low/uncertain ACSM adherence. A meta-analysis was performed utilising Review Manager5.4.1 to assess the effects of ACSM adherence on depression in hemodialysis patients.

Results

This meta-analysis incorporated a total of 19 randomized controlled trials, involving 1,285 patients. The mean age of the patients ranged from 33.2 to 70 years, and the average body mass index (BMI) fluctuated between 23.3 and 28.81 kg/m2. Males accounted for a relatively larger proportion of the participants. Among these trials, 14 were classified as having high ACSM adherence, while 5 were categorized as having low or uncertain adherence. Overall, exercise markedly improved depression in hemodialysis patients (SMD: -0.63, 95% CI: -0.87, -0.39; p < 0.05). The high ACSM adherence group showed greater improvement relative to the low/uncertain adherence group (SMD: -0.66 vs. -0.56). No notable disparities were noted in the effects of exercise duration or patient age on depression outcomes between the subgroups (p = 0.86, p = 0.48).

Conclusion

Exercise interventions that exhibit high adherence to the ACSM guidelines prove to be more efficacious in alleviating depression among hemodialysis patients as compared to those with low or uncertain adherence levels.

Effects of physical activity on depressive and anxiety symptoms of women in the menopausal transition and menopause: a comprehensive systematic review and meta-analysis of randomized controlled trials

BACKGROUND

Depression and anxiety may significantly affect women in the menopausal transition and menopause. In addition to traditional treatment strategies such as hormone therapy, antidepressants, and psychotherapy, physical activity (PA) have been increasingly studied, but there is no consensus about their role in menopausal women with depression and anxiety.

OBJECTIVE

The current study aimed to evaluate the effect of PA on the severity of depressive (DS) and anxiety (AS) symptoms in women during the menopausal transition and menopause.

METHODS

We searched for relevant published studies in PubMed, Embase, Web of Science, Cochrane Library, and CINAHL prior to 8 April 2024, focusing on randomized controlled trials documenting the effect of physical activity on DS and AS, and assessed study quality using the Newcastle-Ottawa Scale.

RESULTS

The data used for meta-analysis were derived from 21 studies (DS, n = 9; AS, n = 1; DS and AS combined, n = 11) involving 2020 participants. The results showed that PA groups demonstrated a statistically significant effect of depressive symptoms versus controls (DS [SMD: -0.66, 95% CI: -0.99 to -0.33; P < 0.001]; AS [SMD: -0.55, 95% CI: -0.82 to -0.27; P < 0.001]). As subgroup analyses demonstrated, physical exercise also reduced depressive symptom of women in menopausal status (SMD =-0.56, 95% CI: -0.96 to - 0.17, p = 0.006, I2 = 69%), postmenopausal status (SMD =-0.94, 95% CI: -1.46 to - 0.42, p = 0.0004, I2 = 94%), and both in menopausal transition and postmenopausal status (SMD =-0.30, 95% CI: -0.49 to - 0.12, p = 0.001, I2 = 0%), while it only reduced anxiety symptom of postmenopausal women (SMD =-0.96, 95% CI: -1.49 to - 0.43, p = 0.0004, I2 = 89%). Low-intensity and moderate-intensity exercise both produced increasingly benefits over depressive and anxiety symptoms. However, there is no statistically significant effect of exercise intensity on both depressive symptom and anxiety symptom.

CONCLUSION

Physical activities with low to moderate intensity can impart remarkable improvements for managing menopausal women with depression and anxiety.

Psychological responses to acute exercise in patients with stress-induced exhaustion disorder: a cross-over randomized trial

BACKGROUND

Understanding psychological responses to acute exercise, defined as a single bout of physical exercise, in clinical populations is essential for developing tailored interventions that account for the psychological benefits and challenges of exercise. Given its effectiveness in reducing symptoms in various psychological disorders, exercise should be further explored in Exhaustion Disorder ICD-10-SE: F43.8A (ED), characterized by persistent exhaustion following long-term psychosocial stress. Currently, no studies address the psychological responses to acute exercise in ED patients.

AIMS

This study aims to (1) compare the psychological responses to acute exercise between ED patients and healthy controls and (2) assess response differences between low and moderate exercise intensities.

METHODS

We conducted a two-armed cross-over trial comparing ED patients (n = 30) and healthy controls (n = 30). Participants completed a 22-min exercise at low or moderate intensity on a cycle ergometer, on separate occasions, in randomized order. The primary outcome was perceived fatigue (POMS); secondary outcomes included feelings of energy, anxiety, stress, exertion, and psychological discomfort, measured before, during, and up to 24 h post-exercise. Exercise effects were assessed using repeated measures analysis of variance.

RESULTS

ED patients reported higher levels of exertion, psychological discomfort, fatigue, anxiety, and stress but lower energy throughout the trial compared to controls. Unlike controls, the ED group showed significant fatigue and stress reductions post-exercise (p < 0.05). Additionally, ED patients showed a more elevated energy after moderate-intensity exercise compared to controls (p < 0.05). Both groups experienced anxiety reductions post-exercise, with no group interactions over time. No differences were observed between pre- and 6 or 24 h post-exercise in any variables. The only intensity effect (p < 0.05) in the ED patients was a more pronounced energy decline 30 min after moderate-intensity exercise.

CONCLUSIONS

A 22-min exercise session was perceived as more strenuous by patients with exhaustion disorder (ED) and generated greater improvements in feelings of fatigue, energy, and stress compared to healthy individuals without delayed negative effects. These findings highlight the specific psychological responses in ED to exercise and can inform intervention design tailored specifically to this population.

Associations between device-measured and self-reported physical activity and common mental disorders: Findings from a large-scale prospective cohort study

OBJECTIVES

To investigate the associations between device-measured and self-reported physical activity (PA) and incident common mental disorders in the general population.

DESIGN AND SETTING

Large-scale prospective cohort study.

PARTICIPANTS

Using the UK Biobank data, a validated PA questionnaire was used to estimate self-reported weekly PA in 365 656 participants between 2006 and 2010 while 91 800 participants wore wrist-worn accelerometers for 7 days in 2013-2015 to derive objectively measured PA. All the participants were followed up until 2021.

MAIN OUTCOME MEASURES

Incidences of depression and anxiety were ascertained from hospital inpatient records. Cox proportional hazards models and restricted cubic splines were used to assess the associations between subjectively and objectively measured PA and common mental disorders.

RESULTS

During a median follow-up of 12.6 years, 16 589 cases of depression, 13 905 cases of anxiety and 5408 cases of comorbid depression and anxiety were documented in the questionnaire-based cohort. We found J-shaped associations of self-reported PA with incident risk of depression and anxiety, irrespective of PA intensities. The lowest risk for depression occurred at 550, 390, 180 and 560 min/week of light-intensity PA (LPA), moderate-intensity PA (MPA), vigorous-intensity PA (VPA) and moderate-to-vigorous PA (MVPA), respectively. During a median follow-up of 6.9 years, a total of 2258 cases of depression, 2166 cases of anxiety and 729 cases of comorbid depression and anxiety were documented in the accelerometer-based cohort. We found L-shaped associations of device-measured MPA and VPA with incident depression and anxiety. MPA was adversely associated with incident depression and anxiety until 660 min/week, after which the associations plateaued. The point of inflection for VPA occurred at 50 min/week, beyond which there was a diminished but continued reduction in the risks of depression and anxiety.

CONCLUSION

Different patterns of associations between self-reported and device-measured PA and mental health were observed. Future PA guidelines should fully recognise this inconsistency and increasingly employ objectively measured PA standards.

Association between 24-hour movement behavior and depression in college students: A compositional data analysis

BACKGROUND

Evidence strongly suggests that moderate-to-vigorous physical activity (MVPA) can help reduce symptoms of depression. However, the relationship between 24-h movement behaviors and depressive symptoms, as well as the potential substitution effects between different behaviors, remains unclear. Therefore, this study seeks to investigate how the time spent in one behavior relative to others is associated with depressive symptoms.

METHODS

The study recruited 366 participants, who had their levels of MVPA, light PA (LPA), and sedentary behavior (SB) recorded using tri-axial accelerometers over 7 consecutive days. Participants also self-reported their sleep duration (SLP). Depression scores were measured using the Center for Epidemiological Studies Depression Scale (CESD). Using compositional linear regression, the study explored the connections between different compositions of time spent in movement behaviors and depression symptom scores.

RESULTS

Spending more time on LPA and MVPA relative to other behaviors were associated with lower depression scores, whereas a higher proportion of SB relative to other activities was linked to increased depression scores. Reallocating time spent on SB to LPA and MVPA was associated with decreased depression scores.

LIMITATION

This study is a cross-sectional research design, and causality cannot be inferred. In addition, the sampling method of this study may have imposed some limitations on the representativeness of the sample. Further longitudinal studies could be conducted by selecting a large, representative sample.

CONCLUSION

Within the spectrum of 24-h movement behaviors, increasing the duration of LPA and MVPA emerges as advantageous for reducing depression scores, suggesting a potential benefit in reallocating SB to PA, especially MVPA.

Physical activity levels are associated with depressive symptoms: A cross-sectional study of 58,445 adults

INTRODUCTION

Depression is the leading cause of mental health-related illnesses and disabilities. Physical activity (PA) has been included as part of therapeutic approaches for patients with depression. This study aimed to investigate the associations between depressive symptoms and PA levels in a large representative cohort of Brazilian adults and older individuals.

METHODS

Data from 58,445 Brazilian adults (68.6 % males and 31.4 % females) aged 18 years or older (42.2 ± 10 years) who participated in health screening initiatives between 2008 and 2022 at the Center for Preventive Medicine at a quaternary hospital in Sao Paulo, Brazil were analyzed. Standardized health data (anthropometric, laboratory, clinical, and behavioral) were collected. A hierarchical regression model was used to examine the associations based on the presence and absence of depressive symptoms.

RESULTS

In the final model, age, gender (female), body mass index (BMI) (each kg/m2), presence of hypertension, presence of diabetes mellitus, risk of alcohol consumption, smoking status, and perceived stress were associated with higher odds of depressive symptoms. However, PA levels were associated with lower odds of depressive symptoms.

CONCLUSION

The findings revealed that any level of PA was independently and significantly associated reduced risk of depressive symptoms.

The Relationship Between Physical Activity Levels and Periodontal Health Status Among College Students: A Cross-Sectional Study

Objective

This study aimed to investigate the relationship between physical activity levels and periodontal health status among college students in Shanghai, with the goal of informing oral health policy recommendations.

Methods

A cross-sectional study was conducted from March 2023 to March 2024 involving 120 university students aged 18-29. Data was collected using the World Health Organization (WHO) oral health survey methods. Periodontal status was assessed using the Community Periodontal Index (CPI), and physical activity was measured with a simplified version of the International Physical Activity Questionnaire (IPAQ). Data analysis was performed using Statistical Package for the Social Sciences (SPSS) version 27.0 (IBM, USA), employing chi-square tests and multivariable logistic regression.

Results

Among the participants (77 males, 43 females), 70% met physical activity guidelines. Adjusting for gender, age, tooth brushing frequency, and dental floss use, insufficient physical activity was associated with higher odds of periodontitis (adjusted model: OR = 5.293, 95% CI = 1.334 to 20.993, p = 0.018). High-intensity physical activity significantly reduced the incidence of periodontitis (p = 0.006), while sedentary behavior showed no significant correlation (p = 0.176).

Conclusion

Promoting physical activity among college students may enhance periodontal health, underscoring the need to integrate oral and public health initiatives.

Exercise capacity and the psychosocial effect in preterm born infants - Should we do more?

Physical activity is crucial for children's physical, cognitive, and social development, reducing the risk of non-communicable diseases and improving overall well-being. A major legacy of extremely preterm delivery is respiratory limitation with reduced lung function and decreased exercise capacity which can be further exacerbated by inactivity and deconditioning. Strategies to increase incidental physical activities in early childhood and participation in sport and more formal exercise programmes in middle childhood have the potential to optimize cardiopulmonary function, improve quality of life, and foster social interactions in childhood and beyond, thereby providing benefits that extend far beyond the physical domain. Intervention strategies such as supervised aerobic and resistance training, and incorporation of physical activity into daily routines have shown promise in increasing activity levels and improving exercise capacity in this population. Engaging families and tailoring programs to individual needs are crucial for the success of these interventions. Overall, a holistic approach that promotes increased physical activity and addresses psychosocial barriers is essential for optimizing the health, well-being, and quality of life of preterm-born children. Further research and development of effective, long-term intervention programs are needed to support these vulnerable individuals throughout childhood and into adulthood.

Relationship between physical activity and depressive symptoms in stroke survivors: a cross-sectional study of 1,140 individuals

OBJECTIVES

To investigate the relationship between physical activity and depressive symptoms in stroke survivors.

DESIGN

A cross-sectional study utilizing National Health and Nutrition Examination Survey (NHANES) 2007-2018 data, employing propensity score matching to control for confounders.

PATIENTS

1,140 stroke survivors from NHANES, assessing depressive symptoms through the Patient Health Questionnaire-9 (PHQ-9) conducted via family interview or a mobile examination centre examination.

METHODS

PA was surveyed concurrently with the PHQ-9, categorized into vigorous, moderate, and moderate-to-vigorous intensities. Propensity score matching was used to match participants based on their activity levels, and the relationship between physical activity and depressive symptoms was analysed by logistic regression.

RESULTS

Among all the subjects, 225 individuals had significant depressive symptoms. If vigorous-intensity PA duration is longer than 75 min (odds ratio [OR] = 0.41, 95% CI 0.21-0.75) or longer than 150 min (OR = 0.42, 95% CI 0.19-0.85), and moderate-intensity physical activity duration is longer than 150 min (OR = 0.59, 95% CI 0.38-0.90) or between 150 and 300 min (OR = 0.36, 95% CI 0.15-0.77), and moderate-to-vigorous PA duration is greater than 150 min (OR = 0.61, 95% CI 0.40-0.91) or exceeding 300 min (OR = 0.50, 95% CI 0.31-0.78), this might be associated with lower depressive symptoms.

CONCLUSION

Regular physical activity, particularly of moderate or higher intensity, is associated with milder depressive symptoms in stroke survivors, suggesting the potential for non-pharmacological intervention.

Physical activity intensity and older adolescents' stress: The 'STress-Reactivity after Exercise in Senior Secondary EDucation' (STRESSED) 3-arm randomised controlled trial

OBJECTIVES

Late adolescence (15-19 years) is a period of heightened susceptibility to stress, but regular physical activity may attenuate reactivity to stressors. We aimed to explore the effects of physical activity intensity on older adolescents' stress-reactivity and self-reported mental health.

DESIGN AND METHODS

Three-arm randomised controlled trial in New South Wales, Australia (April-June 2021). Thirty-seven older adolescents (16.1 ± 0.2 years, 59.5 % female) were randomised to: i) non-active control (CON), ii) light-intensity physical activity (LPA), or iii) moderate-to-vigorous-intensity physical activity (MVPA). Physical activity groups participated in 2 x 20-min sessions/week for 6 weeks. Salivary cortisol (sCort) reactivity to induced stress was assessed using the Trier Social Stress Test for Groups and quantified as area under the curve (sCortAUC; Primary outcome). Secondary outcomes included peak cortisol (sCortPeak), subjective-reactivity, perceived stress, and non-specific psychological distress. Group differences were assessed using multiple linear regression and quantified using Cohen's d.

RESULTS

No statistically significant effects were observed for sCortAUC or sCortPeak and the pattern of effects for subjective-reactivity was inconsistent. Effects for self-reported mental health were also non-significant (p > .05 for all) but of meaningful magnitude, favouring LPA and MVPA over CON (d's = -0.38 to -0.54). Delivery fidelity was high, satisfaction was moderate-to-high, and there was no evidence of harm. However, recruitment, retention for sCort measures, and adherence were lower than expected.

CONCLUSION

Suboptimal recruitment, retention, and adherence limited our ability to conclude on the effect of physical activity intensity on older adolescents' sCort-reactivity to induced stress. We observed potentially meaningful effects on self-reported mental health for both physical activity conditions, which could be confirmed in a future powered trial.

MoodMover: Development and usability testing of an mHealth physical activity intervention for depression

Background

Physical activity (PA) is recognized as a modifiable lifestyle factor for managing depression. An application(app)-based intervention to promote PA among individuals with depression may be a viable alternative or adjunct to conventional treatments offering increased accessibility.

Objective

This paper describes the early stages of the development process of MoodMover, a 9-week app-based intervention designed to promote PA for people with depression, including its usability testing.

Methods

Development of MoodMover followed the initial stages of the Integrate, Design, Assess, and Share (IDEAS) framework. The development process included (1) identifying intervention needs and planning; (2) intervention development; and (3) usability testing and refinement. Usability testing employed a mixed-methods formative approach via virtual semi-structured interviews involving goal-oriented tasks and administration of the mHealth App Usability Questionnaire (MAUQ).

Results

Drawing on formative research, a multidisciplinary research team developed the intervention, guided by the Multi-Process Action Control framework. Nine participants engaged in the usability testing with the MoodMover prototypes receiving an average MAUQ score of 5.79 (SD = 1.04), indicating good to high usability. Necessary modifications were made based on end-users' feedback.

Conclusions

The development of MoodMover, the first theoretically informed app-based PA intervention for individuals with depression, may provide another treatment option, which has wide reach. The comprehensive usability testing indicated interest in the app and strong perceptions of usability enabling a user-centered approach to refine the app to better align with end-users' preferences and needs. Testing the feasibility and preliminary efficacy of the refined MoodMover is now recommended.

Successful Aging in US Veterans with Mental Disorders: Results From the National Health and Resilience in Veterans Study

OBJECTIVES

To determine the prevalence and correlates of successful aging in US veterans who screened positive for current major depressive disorder (MDD), generalized anxiety disorder (GAD), and/or posttraumatic stress disorder (PTSD).

METHODS

In a nationally representative sample of 475 US military veterans (mean age=58.3, SD=14.7; range 24-92) who screened positive for MDD, GAD, and/or PTSD, multivariable logistic regression and relative importance analyses were conducted to identify independent correlates of successful aging.

RESULTS

One-in-five (20.6%) veterans rated themselves as aging successfully. Resilience and gratitude were the strongest positive correlates of successful aging, accounting for 38.1% and 32.4% of the explained variance, respectively. Greater somatic symptoms were the strongest negative correlate, accounting for 11.2% of the explained variance. Higher gratitude moderated the negative association between somatic symptoms and successful aging.

CONCLUSIONS

Positive psychiatry interventions targeting psychosocial factors such as resilience and gratitude may help promote successful aging among US veterans with mental disorders.

Walking self-confidence and lower levels of anxiety are associated with meeting recommended levels of physical activity after hip fracture: a cross-sectional study

PURPOSE

To explore whether psychological factors are associated with ability to meet recommended physical activity thresholds after hip fracture.

MATERIALS AND METHODS

Cross-sectional observational study of 216 community-dwelling adults aged ≥65 years after hip fracture (mean age 79 SD 7 years, 70% female). Multiple ordinal regression analysis determined factors associated with meeting physical activity thresholds related to positive health outcomes: 4,400 and 7,100 daily steps. Explanatory variables were: walking self-confidence; falls self-efficacy; depression; anxiety; co-morbidities; previous gait aid use; nutritional status; age; and gender.

RESULTS

Forty-three participants (20%) met the lower threshold of ≥4,400 to <7,100 steps and thirty participants (14%) met the upper threshold of ≥7,100 steps. Walking self-confidence was positively associated with meeting higher physical activity thresholds (adjusted odds ratio [AOR] 1.32: 95% CI 1.11 to 1.57, p = 0.002). Age (AOR 0.93: 95% CI 0.89 to 0.98, p = 0.003), DASS-21 anxiety score (AOR 0.81: 95% CI 0.69 to 0.94, p = 0.008) and comorbidity index score (AOR 0.52: 95% CI 0.36 to 0.72, p < 0.001) were negatively associated with meeting higher physical activity thresholds.

CONCLUSION

Walking self-confidence and anxiety are potentially modifiable factors associated with meeting physical activity thresholds related to positive health outcomes after hip fracture.

The network analysis of anxiety, depression and academic burnout symptom relationships throughout early, middle, and late adolescence

BACKGROUND

Previous research has explored the associations between anxiety, depression, and academic burnout primarily from a variable-level perspective. However, there is limited understanding of which symptoms might play a significant role in anxiety, depression, and academic burnout among adolescents at different stages.

METHODS

This study included 7,286 adolescents aged 10 to 18. Questionnaires assessed participants' anxiety, depression, and academic burnout. Network analysis was conducted on the overall sample and segmented by early, middle, and late adolescence to explore relationships between symptoms and variations in symptom expression across these stages, aiming to propose effective interventions targeting anxiety, depression, and academic burnout symptoms in early, middle, and late adolescence.

RESULTS

The study found that "feeling that studying is meaningless" emerged as a core symptom in the overall sample. Additionally, "acting or speaking slowly" emerged as a core symptom in early adolescence, while "the thought of dying or hurting" and "feeling bad about yourself, letting your family down" were prominent in middle adolescence, and "easily annoyed or irritable" and "feeling tired" may be prioritized in late adolescence. The varying central symptoms across different adolescent stages suggest the need for targeted interventions.

CONCLUSION

These findings underscore the importance of interventions tailored to specific symptoms to meet the unique needs of adolescents at different developmental stages.

Effects of an acute maximal exercise bout on serum insulin-like growth factor-1 in adults with MDD

Exercise has acute, positive effects on mood and can lead to antidepressant effects over time when repeated regularly. The mechanisms underlying the antidepressant effects of exercise training are not well known, limiting the prescription of exercise training for depression. Serum Insulin-Like Growth Factor-1 (IGF-1) appears dysregulated in those with Major Depressive Disorder (MDD), suggesting MDD could inhibit or alter the IGF-1 response to exercise. In healthy individuals, exercise has been shown to acutely increase serum IGF-1, which may act positively on the dysregulated IGF-1 system in MDD. Therefore, the purpose of this study was to examine the sensitivity of serum IGF-1 levels to an acute maximal exercise bout in adults with MDD and healthy controls. Additionally, clinical and behavioral factors of MDD are likely to affect this system, such as depression severity, antidepressant usage and physical activity habits. Baseline data were used from a larger trial in Germany (SPeED Study) collected from individuals with mild to moderate MDD (n=113) and healthy controls (n=34) that were matched for age, sex, and education. Demographics, depression severity (Hamilton Depression Rating Scale-17), self-reported antidepressant usage, MVPA (International Physical Activity Questionnaire-Short Form), and blood draws before and after a maximal exercise test were collected. Multiple linear regressions were conducted to determine relationships between depression severity, antidepressant usage, and physical activity with peripheral IGF-1 levels following acute exercise. Covariates included demographic factors and IGF-1 pre-exercise (baseline levels). Acute IGF-1 changes occurred similarly in depression (mean ± SD; 11.3 ± 12.9) as well as healthy adults (11.3 ± 20.4: p>0.05). Neither depression severity, antidepressant use, nor regular physical activity were significant predictors of peripheral IGF-1 levels at baseline or following exercise. Individuals with MDD are likely to have favorable exercise-induced IGF-1 changes regardless of clinical and behavioral differences. Acute exercise increases peripheral IGF-1 briefly, and in response to repeated exercise bouts, the IGF-1 system could normalize over time. The normalization of the IGF-1 system might be a possible mechanism underlying mood increases that occur during exercise with exercise training research warranted.

The Pathway Relationship Between Physical Activity Levels and Depressive Symptoms in University Students Mediated by Cognitive Flexibility

OBJECTIVE

To explore the mediating pathway of cognitive flexibility in the relationship between physical activity and depressive symptoms among university students.

METHODS

A cross-sectional design was used to survey 2537 university students using the Physical Activity Rating Scale-3, Patients' Health Questionnaire, and Cognitive Flexibility Inventory. Data analysis was conducted using independent samples t-test, chi-square test, correlation analysis, one-way ANOVA, and mediation analysis.

RESULTS

A statistically significant negative correlation exists between the intensity of physical activity and depression symptom scores (r = -0.104, p < 0.01). The intensity of physical activity demonstrates a statistically significant positive correlation with controllability (r = 0.109, p < 0.01). A marked negative correlation is observed between depressive symptoms and controllability scores (r = -0.367, p < 0.01). The total effect of physical activity intensity on depressive symptoms was quantified as -0.3542 (95% CI: -0.5439 to -0.1645). The direct effect was found to be -0.2199 (95% CI: -0.3981, -0.0417), while the mediating effect of controllability was calculated to be -0.1343 (95% CI: -0.2145 to -0.0630).

CONCLUSION

Increased engagement in physical activity among university students is associated with a reduction in their depressive symptom scores. Controllability serves as a mediating factor in the relationship between physical activity and depressive symptoms among university students.

Cross sectional associations of physical activity and sleep with mental health among Chinese university students

OBJECTIVE

This study aimed to examine the levels of physical activity (PA), sleep, and mental health (MH), specifically depression, anxiety, and stress, among Chinese university students. It also aimed to analyze the influencing factors of MH, providing a theoretical foundation for developing intervention programs to improve college students' mental health.

METHODS

A stratified, clustered, and phased sampling method was employed. In September 2022, a survey was conducted among 36,756 university students from 104 higher education institutions across 31 provinces, autonomous regions, and municipalities in China. The participants' PA behaviors, sleep patterns, depressive symptoms (use the CES-D), anxiety symptoms (use the GAD-7), smoking and drinking behaviors, and demographic information were assessed through an online questionnaire using Questionnaire Star software.

RESULTS

A total of 30,475 valid questionnaires were completed. The proportion of university students engaging in light-intensity PA was 77.6%. The prevalence of insufficient sleep was 39.5%, whereas the prevalence of poor sleep quality was 16.7%. The prevalence of depressive symptoms was 10%, and the prevalence of anxiety symptoms was 23.3%. Binary logistic regression analysis revealed that engaging in moderate to high-intensity PA and having sufficient and high-quality sleep were associated with a lower likelihood of depressive symptoms (OR = 0.207-0.800, P < 0.01), whereas appropriate sleep duration and higher sleep quality were associated with a lower likelihood of anxiety symptoms (OR = 0.134-0.827, P < 0.001).

CONCLUSION

The intensity of PA among university students is predominantly light, and the reported rate of insufficient sleep is relatively high. Moderate to high-intensity PA and sufficient high-quality sleep may alleviate MH issues among college students, with an interaction effect observed among PA, sleep, and depression symptoms. Future studies should further explore targeted interventions combining PA and sleep behaviors to enhance the MH of university students.

Combined association of physical activity and depressive symptoms with cardiometabolic risk factors in Chilean adults

Cardiometabolic risk factors such as obesity, raised blood pressure, high blood glucose and dyslipidemia are emerging health concerns worldwide. Therefore, the aim of this study was to estimate the combined association between physical activity and depressive symptoms with cardiometabolic risk factors in Chilean adults. Data was obtained from the National Health Survey of Chile 2016-2017, with a sample of 5995 adult participants. Assessment of Physical activity and depressive symptoms were done using the Global Physical Activity Questionnaire (GPAQ) and the CIDI ShortForm (CIDI-SF), respectively. Multivariable logistic regression was performed to estimate the combined association of physical activity and depressive symptoms with cardiometabolic risk factors. Participants in the category ≥ 150 min/Depressive symptoms had the highest prevalence of overweight (OR: 1.55, 95% CI: 1.17-2.05), obesity (OR: 1.97, 95% CI: 1.49-2.59) and high waist circumference (OR: 1.63, 95% CI: 1.39-1.92). Participants in the < 150 min/No depressive symptoms category had a lower prevalence of overweight/obesity (OR: 0.68, 95% CI: 0.60-0.78) and a 25% reduced high triglycerides prevalence, in comparison with the active category with no depressive symptoms. There is a positive association between depressive symptoms and overweight, obesity and waist circumference among subjects that complete physical activity recommendations but have depressive symptoms.

Global screening of health behaviors: Introducing Lev-screening (Lev-s)-development and psychometric evaluation

Poor health behaviors have been identified as a critical factor for the burden on healthcare systems and individual suffering. However, comprehensive assessment of health behaviors is time-consuming and often neglected. To address this, we introduce the Lev-screening (Lev-s), a new, brief tool that covers multiple health behaviors. The Lev-s assesses ten health behaviors-physical activity, diet, alcohol use, tobacco use, illegal drug use, sleep, social relations, meaningful activities, sexual health, and screen health-using 33 items. This article details the development and psychometric evaluation of Lev-s with a sample of 2,279 participants aged 18-87. Test-retest reliability estimated as intra-class correlation coefficients for the different health behaviors ranged from .71 to .98 (n = 157), indicating moderate to excellent reliability. Lev-s showed associations with quality of life, demonstrated inter-correlations among included health behaviors, and detected group differences between individuals with and without neurodevelopmental conditions. The Lev-s exhibits satisfactory psychometric properties and holds promise as an efficient tool for screening of health behaviors.

Relationship Between Physical Exercise and Risk of Depression: An Assessment of Intermediate Variables Through Self-Assessed Health Status and Life Satisfaction in the Chinese Family Tracking Survey (CFPS) Data

Objective

Depression is a potential health killer. As an important means of preventing various human diseases, physical exercise plays an important role in reducing the risk of depression. Using data from the Chinese Household Tracking Survey, this study analyzed the mechanisms by which physical exercise, self-rated health and life satisfaction reduce the risk of depression.

Methods

The data for this study comes from the China Family Panel Studies (CFPS) released by the China Social Science Survey Centre of Peking University. The 2020 survey data was used as the sample, which contained a total of 21,057 individuals. The study variables were analyzed in sequence for reliability and validity, correlation analysis, regression analysis, structural equation model testing, and bias-corrected percentile Bootstrap testing using SPSS 23.0 software and Hayes' (2013) Process plug-in.

Results

Physical exercise was significantly positively correlated with self-assessed health status and satisfaction of life (β = 0.049, p < 0.01; β = 0.075, p < 0.01), and significantly negatively correlated with risk of depression (β = -0.022, p < 0.01); self-assessed health status was significantly positively correlated with satisfaction of life (β = 0.440, p < 0.01), and significantly negatively correlated with risk of depression (β = -0.047, p < 0.01); satisfaction of life was significantly negatively correlated with risk of depression (β = -0.137, p < 0.01).

Conclusion

Physical exercise not only negatively predicted the risk of depression, but also indirectly predicted the risk of depression through the independent mediating effects of self-assessed health status and satisfaction of life, as well as chain mediating effects. There were no differences in the effects of physical exercise on depression risk by age, gender and marital status. Significant differences in the effect of physical exercise on depression risk were found among groups with different places of residence.

Optimal intensity and dose of exercise to improve university students' mental health: a systematic review and network meta-analysis of 48 randomized controlled trials

BACKGROUND

A systematic evaluation and network meta-analysis (NMA) using randomized controlled trials (RCTs) was conducted to investigate the effects of different exercise intensities and dosages on the mental health of college students.

METHODS

A systematic search of eight electronic databases of RCTs involving mental health exercise interventions for college students was conducted, which included data from the inception of the databases through July 2024. Two independent reviewers assessed the quality of the literature. Pairwise, network, and dose‒response meta-analyses were conducted via random-effects models to analyze the effects of exercise on college students' mental health.

RESULTS

A total of 48 RCTs (3951 patients) were included. Light, moderate, and vigorous exercise were all significantly effective at reducing symptoms of depression, anxiety and stress, whereas very light exercise was only effective at reducing symptoms of depression and stress. Surface under the cumulative ranking curve (SUCRA) probability ranking revealed that vigorous exercise had the highest probability of being the best intervention intensity to improve depression and stress symptoms, and the best exercise intensity to improve anxiety symptoms was moderate. The minimum threshold for overall exercise intervention for depressive symptoms was 150 METs-min per week, the benefits provided after doses above 1300 METs-min per week were less pronounced, and the predicted maximum significant response dose was 860 METs-min per week, which was the same as the predicted data for moderate exercise.

CONCLUSION

Very light, light, moderate, and vigorous exercise are all potentially effective exercise intensities for improving the mental health of college students, with no significant difference in effectiveness across the four exercise intensities. SUCRA rankings revealed that vigorous exercise is the most effective intervention for depression and stress and that moderate exercise is the most effective intervention for anxiety. Exercise interventions for depressive symptoms have a low dosage threshold, are simple and easy to administer, and are good treatments for psychological problems in college students.

Optimizing antidepressant benefits: Effect of theta burst stimulation treatment in physically active people with treatment-resistant depression

Theta burst stimulation (TBS) is a promising therapy for treatment-resistant major depressive disorder (MDD), but a significant proportion of individuals do not respond adequately, necessitating alternative approaches. This study explores whether individuals meeting minimum recommended physical activity levels demonstrate better responses to TBS compared to physically inactive individuals. Using data from a randomized controlled trial (n = 43), participants were categorized as physically active or inactive based on baseline International Physical Activity Questionnaire (IPAQ) scores. Depression scores (Hamilton Rating Scale for Depression, 17-item; HRSD-17) were assessed at baseline, 4, and 6 weeks of TBS treatment. A significant Time X Group effect adjusted for age and baseline depression was observed. Physically active individuals consistently exhibited lower depression scores across time points. At 4 and 6 weeks, there was a significant increase in between-group differences, indicating that the physically active group derived greater benefits from treatment. At 6 weeks, a significantly higher proportion of responders (≥50 % HRSD-17 reduction) were observed in the physically active compared to inactive group. Physical activity significantly contributed to regression and logistic models predicting treatment response. These findings support the potential role of baseline physical activity in enhancing TBS therapy for MDD.

The Role of Behavioral Factors on Chronic Diseases-Practice and Knowledge Gaps

Background: Behavioral factors, such as smoking, alcohol consumption, stress, poor diet, and physical inactivity, but also sleep deprivation and negative social connections, play a critical role in the development and progression of major chronic diseases. These include cardiovascular diseases, diabetes, chronic respiratory conditions, and cancers. Methods: The objective of this review is to explore the influence of these modifiable risk factors on the global burden of chronic diseases and assess the potential impact of public health interventions and policy changes. Results: The evidence highlights a significant association between behavioral risk factors and increased morbidity and mortality from chronic diseases. Public health interventions and policy changes targeting these modifiable behaviors have shown substantial potential in reducing the prevalence and impact of chronic conditions. Strategies such as smoking cessation programs, dietary improvements, physical activity promotion, and stress reduction are critical in mitigating these risks. Conclusions: Addressing modifiable behavioral factors is essential for the prevention and control of chronic diseases. Bridging the gap between current knowledge and effective implementation of interventions is crucial for improving population health outcomes. Public health strategies focused on modifying key behavioral risks can significantly reduce the burden of chronic diseases, thereby improving overall health and reducing healthcare costs.

Promoting workplace psychological wellbeing through Yoga and Tai Chi classes in female university employees

Introduction

Academic environments are known for their high demands, often resulting in significant distress among employees. Thus, identifying effective intervention strategies to mitigate workplace stress is essential. The present study aims to evaluate the potential benefits of mind-body interventions (i.e., Yoga and Tai Chi) on the psychological wellbeing and perceived mental and physical health of female university employees.

Methods

A total of 166 female university employees and faculty members participated in 10 sessions of Tai Chi or Yoga. They completed self-report questionnaires assessing ruminative thoughts, somatic anxiety, general distress, perceived physical and mental health, and assertive and cooperative behaviors before and after the 10 Tai Chi/Yoga sessions. Additionally, participants completed a state anxiety questionnaire before and after Tai Chi/Yoga second and second-to-last lessons.

Results

Results showed significant differences between scores pre and post Tai Chi and Yoga programs, with lower ruminative thoughts (p = 0.007), lower somatic anxiety (p < 0.001), and higher perceived mental health (p = 0.038) at the end of the programs (i.e., after 10 sessions) compared to the beginning. Moreover, significant differences were found in state anxiety scores, with a reduction in state anxiety at the end of the second (p < 0.001) and second-to-last (p < 0.001) lessons compared to the start.

Conclusion

Our findings highlight the potential positive impact of Tai Chi and Yoga programs on the psychological wellbeing and perceived mental health of female university employees. Immediate reductions in state anxiety following single sessions further underscore the potential of these practices for short-term stress relief. Overall, the results support the implementation of mind-body practices in workplace settings to promote a healthier work environment.

Daily Step Count and Depression in Adults: A Systematic Review and Meta-Analysis

Importance

Recent evidence syntheses have supported the protective role of daily steps in decreasing the risk of cardiovascular disease and all-cause mortality. However, step count-based recommendations should cover additional health outcomes.

Objective

To synthesize the associations between objectively measured daily step counts and depression in the general adult population.

Data Sources

In this systematic review and meta-analysis, a systematic search of the PubMed, PsycINFO, Scopus, SPORTDiscus, and Web of Science databases was conducted from inception until May 18, 2024, to identify observational studies using search terms related to physical activity, measures of daily steps, and depression, among others. Supplementary search methods were also applied.

Study Selection

All identified studies were uploaded to an online review system and were considered without restrictions on publication date or language. Included studies had objectively measured daily step counts and depression data.

Data Extraction and Synthesis

This systematic review and meta-analysis followed the Preferred Reporting Items for Systematic Reviews and Meta-analyses and Meta-analysis of Observational Studies in Epidemiology reporting guidelines. Two independent reviewers extracted the published data.

Main Outcomes and Measures

Pooled effect sizes (correlation coefficient, standardized mean difference [SMD], and risk ratio [RR]) with 95% CIs were estimated using the Sidik-Jonkman random-effects method.

Results

Thirty-three studies (27 cross-sectional and 6 longitudinal [3 panel and 3 prospective cohort]) involving 96 173 adults aged 18 years or older (range of mean [SD] ages: 18.6 [0.6] to 91.2 [1.6] years) were included. Daily steps were inversely correlated with depressive symptoms in both cross-sectional and panel studies. Compared with fewer than 5000 steps/d, pooled SMDs from cross-sectional studies revealed that 10 000 or more steps/d (SMD, -0.26; 95% CI, -0.38 to -0.14), 7500 to 9999 steps/d (SMD, -0.27; 95% CI, -0.43 to -0.11), and 5000 to 7499 steps/d (SMD, -0.17; 95% CI, -0.30 to -0.04) were significantly associated with fewer depressive symptoms. Pooled estimates from prospective cohort studies indicated that participants with 7000 or more steps/d had reduced risk of depression compared with their counterparts with fewer than 7000 steps/d (RR, 0.69; 95% CI, 0.62-0.77). An increase of 1000 steps/d was associated with a lower risk of depression (RR, 0.91; 95% CI, 0.87-0.94).

Conclusions and Relevance

In this systematic review and meta-analysis of 33 observational studies involving 96 173 adults, higher daily step counts were associated with fewer depressive symptoms in cross-sectional and longitudinal studies in the general adult population. Further prospective cohort studies are needed to clarify the potential protective role of daily steps in mitigating the risk of depression during adulthood.

Identifying modifiable factors and their joint effect on brain health: an exposome-wide association study

Considerable uncertainty remains regarding the associations of multiple factors with brain health. We aimed to conduct an exposome-wide association study on neurodegenerative disease and neuropsychiatry disorders using data of participants from the UK Biobank. Multivariable Cox regression models with the least absolute shrinkage and selection operator technique as well as principal component analyses were used to evaluate the exposures in relation to common disorders of central nervous system (CNS). Restricted cubic splines were conducted to explore potential nonlinear correlations. Then, weighted standardized scores were generated based on the coefficients to calculate the joint effects of risk factors. We also estimated the potential impact of eliminating the unfavorable profiles of risk domains on CNS disorders using population attributable fraction (PAF). Finally, sensitivity analyses were performed to reduce the risk of reverse causality. The current study discovered the significantly associated exposures fell into six primary exposome categories. The joint effects of identified risk factors demonstrated higher risks for common disorders of CNS (HR = 1.278 ~ 3.743, p < 2e-16). The PAF varied by exposome categories, with lifestyle and medical history contributing to majority of disease cases. In total, we estimated that up to 3.7 ~ 64.1% of disease cases could be prevented.This study yielded modifiable variables of different categories and assessed their joint effects on common disorders of CNS. Targeting the identified exposures might help formulate effective strategies for maintaining brain health.

Association of physical activity and sedentary behaviour with depressive symptoms in Chinese adults

This study aims to examine the independent and joint associations of physical activity (PA) and sedentary behaviour with depressive symptoms. A population-based cross-sectional study conducted in China included 17,861 adults. PA and sedentary behaviour were assessed using the International Physical Activity Questionnaire. Depressive symptoms were determined by the 9-item Patient Health Questionnaire score ≥10. Logistic regression models were used to calculate the odds ratios (ORs) and corresponding 95% confidence intervals (CIs). The prevalence of depressive symptoms among all participants was 20.6% (3679/17861). Higher levels of PA were inversely associated with depressive symptoms, whereas prolonged sedentary behaviour was associated with increased odds of depressive symptoms. The positive associations between sedentary behaviour and depressive symptoms remained significant, regardless of PA levels. In joint analyses, the depressive symptoms OR comparing adults who reported low level of PA with the highest tertile of sedentary behaviour to those reporting high level of PA with the lowest tertile of sedentary behaviour was 1.99 (95% CI 1.64 to 2.40). This study indicated that high level of PA may not offset the increased risk of depressive symptoms associated with high amounts of sedentary behaviour, and therefore these behaviours should be considered jointly to obtain optimal prevention effects.

The Impact of Physical Activity and Lifestyle on Mental Health: A Network Analysis

AIM

This study aimed to investigate the association between physical activity (PA), lifestyle, and symptoms of depression, anxiety, and stress.

METHODS

A cross-sectional study was carried out using an online questionnaire. PA (International Physical Activity Questionnaire), lifestyle (Short Multidimensional Inventory Lifestyle Evaluation), and mental health (Depression, Anxiety, and Stress Scale-21) were assessed. Mean scores were compared between groups of physically active and inactive participants, controlling for gender, education, and income. Furthermore, associations were made between the variables, and individual network analyses were carried out for each mental health domain. The sample consisted of 353 individuals (age = 33.8 [12.2], 59.2% women).

RESULTS

In network analyses, PA was indirectly related to depression and stress through the relationship with other lifestyle domains such as diet and nutrition or through stress management and social support. The same path was observed for anxiety; however, a direct partial correlation was also observed between PA and anxiety, suggesting that PA seems to intervene more directly in this aspect of mental health.

CONCLUSION

It is concluded that PA is indirectly (via stress management, diet and nutrition, and social support) associated with depression and stress and has direct and indirect associations (via stress management and social support) with anxiety.

Physical activity interventions for the promotion of mental health outcomes in at-risk children and adolescents: a systematic review

Many young people are exposed to risk factors that increase their risk of mental illness. Physical activity provision is an increasingly popular approach to protect against mental illness in the face of these risk factors. We examined the effectiveness of physical activity interventions for the promotion of mental health outcomes in at-risk children and adolescents. We searched health databases for randomised and non-randomised intervention studies, with no date restriction, and assessed risk of bias using the Cochrane Risk of Bias tools. We present a narrative synthesis of our results accompanied with a summary of available effect sizes. Thirty-seven reports on 36 studies were included, with multi-sport or yoga interventions the most popular intervention approaches (a combined 50% of included studies). Outcomes measured included internalising, self-evaluative, wellbeing, overall symptomatology, resilience, externalising, and trauma outcomes. We found that 63% of between-groups effects favoured the intervention arm, and 83% of within-groups effects favoured an intervention effect. While recognising high risk of bias, our findings provide evidence in support of the effectiveness of physical activity interventions for promoting mental health outcomes in at-risk young people. We encourage further work designed to better understand the intervention characteristics that may lead to positive benefits.

High-intensity interval training for improving cardiometabolic health in children and adolescents: An umbrella review of systematic reviews

High-intensity interval training (HIIT) is an emerging exercise strategy to improve health and fitness, but previous studies have evaluated HIIT interventions across different populations and outcomes. This review aimed to comprehensively synthesize published evidence on the effects of HIIT on key cardiometabolic health parameters in children and adolescents. We searched seven databases until February 2024. Systematic reviews were eligible if they 1) compared HIIT and active/non-active control conditions with meta-analysis, 2) examined cardiorespiratory fitness, body composition and cardiometabolic risk biomarkers, and 3) examined children and adolescents. We included 18 systematic reviews with meta-analysis, including 223 original studies and 13,900 unique participants. HIIT is effective for cardiorespiratory fitness in children and adolescents with diverse health and weight status (median standardized mean difference [SMD] = 0.75). Improvements in body composition and several cardiometabolic risk biomarkers, including systolic blood pressure (median SMD = -0.40), diastolic blood pressure (median SMD = -0.22), triglyceride (median SMD = -0.30), low-density lipoprotein cholesterol (median SMD = -0.90), and high-density lipoprotein cholesterol (median SMD = 0.34), have also been observed following HIIT, with a notably more pronounced effect in youth with overweight/obesity or metabolic disorders. Our umbrella review supports the effectiveness of HIIT in enhancing cardiometabolic health, suggesting its integration into physical activity promotion programmes in schools and communities.

Comparative effectiveness of physical exercise interventions on sociability and communication in children and adolescents with autism: a systematic review and network meta-analysis

OBJECTIVE

To investigate the efficacy of physical activity as a crucial intervention for Autism spectrum disorder (ASD) in clinical settings, we conducted a network meta-analysis to evaluate the effect of various exercise interventions on sociability and communication in individuals with ASD. Our aim was to identify the exercise modalities most conducive to enhancing these essential skills.

METHODS

We searched Web of Science, PubMed, Cochrane Library, Scopus, Embase, and searched Chinese databases from inception to April 2024. We included randomized controlled trials that assessed the effects of different exercise types on sociability and communication in individuals with ASD. Network meta-analysis (NMA) was performed using a frequentist approach, and the node-splitting method was applied to assess inconsistency.

RESULTS

We included 38 original studies published between 2009 and 2024, with a total of 1,382 participants analyzed for sociability outcomes. Results indicated that sports games [SMD = 1.12, 95%CI (0.51, 1.73)], combination therapy [SMD = 1.11, 95%CI (0.13, 2.09)], group ball sports [SMD = 1.06, 95%CI (0.37, 1.75)], and outdoor exercise [SMD = 1.02, 95%CI (0.50, 1.55)] were more effective than passive controls. A total of 25 original literatures were included in the analysis of communication ability, involving 904 subjects, and the results showed that combination therapy [SMD = 1.57, 95% CI (0.74, 2.40)], sports games [SMD = 1.01, 95% CI (0.45, 1.56)], group ball games [SMD = 0.85, 95% CI (0.45, 1.26)], outdoor exercise [SMD = 0.79, 95% CI (0.48, 1.11)], and mind-body exercise [SMD = 0.79, 95% CI (0.29, 1.30)], all of which were more effective than passive controls.

CONCLUSION

Physical exercise plays a significant role in alleviating symptoms and enhancing sociability and communication in individuals with ASD. Our findings highlight that sports games, combination therapy, team ball sports, and outdoor exercise are particularly effective in improving sociability. In terms of communication skills, combination therapy, sports games, team ball sports, outdoor exercise, and mind-body exercise demonstrated the most substantial benefits. These results provide a robust foundation for future interventions aimed at improving the quality of life for individuals with ASD.

The Role of Psychological Factors and Resilience in Mediating Sports Passion in Triathletes

The present study aims to analyze the psychological characteristics associated with the performance of amateur athletes, exploring their relationships with key variables such as resilience, harmonious and obsessive passion, and perception of discomfort. The main objective is to establish the relationship between psychological characteristics and each of the variables used (resilience, personal competence, and acceptance of self and life), and to consider whether these are related to passion (harmonious and obsessive) through a structural equation analysis. The sample was composed of 110 persons: 87 adults (22 females, mean age 40.7 ± 9.1 years; 65 males, mean age in years 42.1 ± 11.9) and 23 adolescents (16 females, mean age 14.8 ± 1.3 years; 7 males, mean age 15.3 ± 2.1 years). Psychological characteristics were assessed using the Psychological Characteristics Related to Performance (CPRD) questionnaire, passion using the Passion Scale instrument, and resilience using the Resilience Scale (RS-14) questionnaire. The analyses were based on a structural equation model analysis (PLS-SEM). The results showed adequate coefficients of determination (R index2) and Stone-Geisser predictive relevance (Q2) for the personal competence resilience factors (R2 = 0.517; Q2 = 0.218) and acceptance of self and life (R2 =.415; Q2 = 0.231), as well as for the passion dimensions harmonious passion (R2 = 0.357; Q2= 0.168) and obsessive passion (R2 = 0.085; Q2= 0.034). In conclusion, a close relationship was demonstrated between psychological characteristics related to sports performance and the variables of resilience and passion (both harmonious and obsessive). In particular, it was confirmed that mental skills and stress management are linked to the dimensions of resilience, and these dimensions influence both types of passion. In addition, team cohesion and personal competence also play a crucial role in the development of passion, highlighting the importance of these factors in the assessment of sports performance and influencing the well-being of amateur athletes in their personal and sports development.

A Longitudinal Study of Loneliness Before the End of the COVID-19 Pandemic: Trajectories, Predictors, and Impact on Chinese Adolescent Mental Health

Background

COVID-19 threatened global health, however little is known about the long-term courses of loneliness and their effect on mental health in adolescents. This study aimed to explore the trajectories of loneliness among adolescents in Taizhou, Zhejiang Province, China, during the last phase of the pandemic. We also aimed to identify risk factors in each loneliness course and the impact of loneliness on emotional problems, peer problems, hyperactivity and conduct problems.

Methods

The study employed multistage cluster sampling to collect four waves of data from 2347 Chinese adolescents (average baseline age of 14.7 years) covering a period of 20 months (October 2021 - May 2023). The UCLA 3-Item Loneliness Scale and the Strengths and Difficulties Questionnaire were utilized to assess loneliness and mental health problems, respectively. Growth mixture modelling was employed to identify latent classes of loneliness trajectories. Associated risk factors were investigated using multinomial logistic regression model. Mixed-effects logistic regression models were constructed to examine the long-term impact of loneliness classes on mental health outcomes.

Results

The overall percentage of loneliness increased from 22.9% at baseline to 32.2% at the fourth wave in our sample. Three classes of loneliness were identified: Decreasing Low Loneliness (58.71%), Increasing Medium Loneliness (36.52%), and Increasing High Loneliness (4.77%). Risk factors for poorer loneliness trajectories included lack of physical exercise habits, poorer mental health literacy, medium or low perceived social support, having study difficulties, being female, higher grades, and lower economic status. Loneliness classes were associated with the severity and variability of emotional problems, peer problems, hyperactivity and conduct problems (ORs for the highest loneliness class: 10.24, 4.21, 3.87, 2.68, respectively). Individuals in the higher loneliness classes experienced a significant increase in these mental health problems over time (p < 0.05 for interactions between loneliness classes and time).

Conclusion

During the last phase of the pandemic, a large proportion of adolescents in our study endured medium to high levels of loneliness with no signs of improvement. Both unfavorable loneliness trajectories adversely affected internalizing and externalizing problems and displayed an upward trend in these difficulties. Results highlight the importance of tackling loneliness and improving mental health in adolescents.

The objectives are to explore the relationship between study stress and anxiety in high school students and the mediating role of physical activity and mobile phone addiction.

DESIGN

A cross-sectional study.

SETTING

129 high schools were randomly selected in 13 cities of Jiangsu province, China.

PARTICIPANTS

High school students aged 16-19 years, age and gender balance. A total of 40 000 questionnaires were distributed, with 32 974 effectively recovered.

PRIMARY AND SECONDARY OUTCOME MEASURES

Questionnaires were administered offline, covering four parts: General Demographics, Learning Stress Scale, International Physical Activity Questionnaire, Mobile Phone Addiction Scale and Generalized Anxiety Scale-7. Data analysis included path analysis and correlation analysis, along with descriptive statistics, independent sample t-test, correlation analysis and structural equation model.

RESULTS

In this study, the proportions of anxiety, high academic pressure, low physical activity level and high mobile phone addiction were 58.18%, 46.48%, 36.40% and 39.26%, respectively. Study stress was positively correlated with anxiety (r=0.130, p<0.01) and mobile phone addiction (r=0.049, p<0.01). Physical activity was negatively correlated with learning stress (r=-0.352, p<0.01), anxiety (r=-0.105, p<0.01) and mobile phone addiction (r=-0.040, p<0.01). The findings were tested by mediating effect analysis that the indirect effect size value of the path 'learning stress → physical activity level → anxiety path' was 0.461, 95% CI of Bootstrap (0.367, 0.554), the mediating effect was significant. The indirect effect size value of the path 'learning stress → mobile phone addiction → anxiety' was 0.072, 95% CI of Bootstrap (0.042, 0.102), and the mediating effect was significant. The indirect effect size value of the path 'learning stress → physical activity level → mobile phone addiction → anxiety' was 0.072, and the 95% CI of Bootstrap (0.226, 0.400), and the mediating effect was significant.

CONCLUSIONS

High school students' learning stress can significantly positively predict anxiety levels. High school students learning stress indirectly predicts anxiety through the independent mediating effect of physical activity and mobile phone addiction, as well as the chain mediating effect of physical activity and mobile phone addiction.

Correlation between the physical activity volume and cognitive and mental capacity among older adult people in China: a cross-sectional study based on the 2020 CHARLS database

Background

Currently, due to the progress of the aging population in China and the government's attention to healthy aging, there is an increasing emphasis on the cognitive function and psychological function of older adult people. Therefore, the aim of our study was to investigate the relationships between physical activity and cognitive and psychological function in order to provide recommendations for exercise guidance.

Methods

The Center for Epidemiologic Studies Depression Scale (CESD-10) was used to assess mental capacity, and cognitive function was evaluated across three domains: orientation, memory and calculation. Total physical activity data were obtained via interviews. Ability of Daily Living (ADL) and Instrumental Ability of Daily Living (IADL) scores were used to determine the presence or absence of daily physical function impairment. Finally, we conducted correlation analysis and logistic regression on participants' physical activity volume (PAV) and their cognitive and psychological functions, respectively.

Results

A total of 5,871 participants who met the inclusion criteria were selected from the China Health and Retirement Longitudinal Study (CHARLS). The prevalence of depression was 8.1, and 31.6% of the older adult participants reported experienced depressive symptoms. Additionally, 15.6% of the older adult individuals had insufficient weekly physical activity, while 3.9% had daily physical function (DPF) impairment. Physical activity volume (PAV) was negatively correlated with the CESD-10 score, as well as with orientation, calculation, and memory.

Conclusion

Our study confirmed that inactive weekly physical activity was associated with an increased risk of depression, cognitive impairment, and DPF impairment among older adult individuals in China.

A novel antidepressant homogeneous polysaccharide YLP-1 from Millettia pulchra ameliorates tryptophan metabolism and SCFAs through modulating gut microbiota

The root of Millettia pulchra (YLS) has been traditionally used as a folk medicine for the treatment of depression and insomnia in the Zhuang nationality of China, and its polysaccharides have potential antidepressant effect. In this study, a novel homogeneous polysaccharide (YLP-1) was purified from the crude polysaccharides of YLS, and it is mainly composed of glucose, arabinose and mannose with molar ratio of 87.25%, 10.77%, and 1.98%, respectively. YLP-1 is a novel α-glucan with the backbone of 1,4-Glcp and branched at C6 of 1,4,6-Glcp to combine 1,4-Manp and 1,5-Araf. The microstructure of YLP-1 displayed a uniform ellipsoidal-like chain morphology and dispersed uniformly in solution. YLP-1 effectively ameliorated depression-like ethological behaviors and restored the decreased catecholamine levels in chronic variable stress (CVS)-induced depression rats. Additionally, it significantly improved the disturbance of gut microbiota induced by CVS stimuli, particularly affecting bacteria that produce short-chain fatty acids (SCFAs), such as bacteria species Lactobacillus spp.. In vitro fermentation study further confirmed that YLP-1 intake could promote SCFAs production by Lactobacillus spp. YLP-1 also mitigated the disruption of tryptophan metabolites in urine and serum. These findings provide evidences for the further development of YLP-1 as a macromolecular antidepressant drug.

Remote exercise services for people with cystic fibrosis: experiences and perceptions from people with cystic fibrosis and members of cystic fibrosis multidisciplinary teams

PURPOSE

This study aimed to explore the experiences and perceptions of people with cystic fibrosis (PwCF) and multidisciplinary team (MDT) members on remote exercise services (RES) and to inform recommendations for future RES.

METHODS

Participants were recruited from an adult CF centre and through social media. Individual online semi-structured interviews were conducted. Interviews were recorded, transcribed verbatim, and thematically analysed.

RESULTS

Themes from MDT members: Accessibility and convenience offered by remote exercise services; Enhanced connections between MDT members and PwCF; Perceived health and wellness benefits of remote exercise services for PwCF; Barriers to engagement; and Suggested improvements for future remote exercise services. Themes from PwCF: Remote exercise enables activity with multifaceted benefits; Perceived limitations of remote exercise services; and Enhancing participation.

CONCLUSIONS

Participants' overall perceptions towards RES were positive, and perceived benefits of RES included time and cost saving, improving work efficiency, and having peer support. Perceived barriers to RES were largely technological or related to lacking visual cues. Perceived recommendations to future RES included personalising exercise options, developing user-friendly platforms, and providing funding for buying equipment.

The influence of physical exercise on negative emotions in adolescents: a meta-analysis

Background

Adolescence is also accompanied by ongoing mood changes (relative to childhood and adulthood), which can trigger more extreme negative emotional responses. Physical exercise alleviates negative emotions and reduces the risk of mental illness. However, the effect of physical exercise on negative emotions in adolescents is unclear, so it is valuable to synthesize previous studies with meta-analysis.

Objective

To examine the influence of physical exercise (PE) intervention on negative emotions in adolescents aged 10 to 19 years.

Methods

We retrieved the articles from PubMed, Web of Science, EBSCO, Cochrane, and Embase up to April 11, 2024. The main search terms were physical exercise, negative emotions, adolescents, randomized controlled trials. The meta-analysis was conducted using Review Manager 5.3. A random-effects model was employed to calculate the standardized mean difference (SMD) and 95% confidence interval (CI). Subgroups were analysed as the type of negative emotions, type of control group, intervention type, duration, time, frequency.

Results

The PE intervention group exhibited a significantly superior improvement in alleviating negative emotions compared to the control group (SMD = -0.59, 95% CI: -0.92 to -0.26, p < 0.01, Z = 3.50, I² = 95%). PE was particularly effective in mitigating adolescent depression (SMD = -0.67, 95% CI = -1.07 to -0.28, p < 0.01, I² = 96%) but did not yield significant results in reducing adolescent anxiety (SMD = -0.29, 95% CI = -0.63 to 0.05, p = 0.10, I² = 95%).

Conclusion

PE intervention can ameliorate negative emotions in adolescents.

Changes in Rest-Activity Rhythms in Adolescents as They Age: Associations With Brain and Behavioral Changes in the ABCD Study

OBJECTIVE

Adolescents with disrupted rest-activity rhythms (RARs), including shorter sleep duration, later sleep timing, and low physical activity levels, are at greater risk for mental health and behavioral problems. It remains unclear whether the same associations can be observed for within-subject changes in RARs.

METHOD

This longitudinal investigation on RARs used Fitbit data from the Adolescent Brain Cognitive Development (ABCD) Study at the 2-year follow-up (FL2) (ages 10-13 years) and 4-year follow-up (FL4) (ages 13-16 years). Good-quality Fitbit data were available for 963 youths at both time points. Changes in RARs from FL2 to FL4, their environmental and demographic contributors, and brain and behavioral correlates were examined.

RESULTS

From FL2 to FL4, adolescents showed decreases in sleep duration and physical activity as well as delayed sleep timing (Cohen d = 0.44-0.75). Contributions of environmental and demographic factors to RAR changes were greatest for sleep timing (explained 10% variance) and least for sleep duration (explained 1% variance). Delays in sleep timing had stronger correlations with behavioral problems including impulsivity and poor academic performance than reductions in sleep duration or physical activity. Additionally, the various brain measures differed in their sensitivity to RAR changes. Reductions in sleep duration were associated with decreased functional connectivity between subcortical regions and sensorimotor and cingulo-opercular networks and with enhanced functional connectivity between sensorimotor, visual, and auditory networks. Delays in sleep timing were mainly associated with gray matter changes in subcortical regions.

CONCLUSION

The current findings corroborate the importance of sleep and physical activity in brain neurodevelopment and behavioral problems in adolescents. RARs might serve as biomarkers for monitoring behavioral problems and be potential therapeutic targets for mental disorders in adolescents.

Understanding the Relationships Between Physical Activity and Climate Change: An Umbrella Review

BACKGROUND

Physical activity is crucial for maintaining health and preventing chronic diseases. However, climate conditions can impact physical activity patterns, and conversely, physical activity can impact climate change. This umbrella review aims to summarize the existing evidence regarding the relationships between physical activity and climate change, as revealed in previous reviews.

METHODS

Systematic reviews and meta-analyses were analyzed. Searches were conducted across GreenFILE, PubMed, and Web of Science databases for peer-reviewed articles published in English. A 2-stage independent screening process was conducted, and methodological quality was assessed using the JBI framework. Standardized data extraction methods were then applied.

RESULTS

Out of 1292 articles retrieved, 7 met all eligibility criteria and were included in the review. Three articles examined physical activity as a primary exposure, 3 focused on the impacts of climate change, and one considered both physical activity and climate change as primary exposures.

CONCLUSIONS

Findings reveal an interplay between climate change and physical activity. While rising temperatures may prompt outdoor activities up to a certain temperature threshold, air pollution and extreme heat can have harmful effects. Active transportation and improved logistics around large-scale sporting events can mitigate climate change by reducing greenhouse gas emissions, but transportation systems linked to sports venues may increase emissions. Research on the reciprocal relationship between climate change and physical activity domains, and integrating the community into climate discussions, is crucial for equity, especially for marginalized communities. Incorporating climate adaptation and mitigation strategies in physical activity infrastructure to minimize environmental impacts is critical.

The Mediating Role of Physical Activity and Self-Rated Health in the Association Between Depression and Quality of Life in Older Europeans: An Analysis Differentiated by Sex

Objectives: This study investigates the mediating role of moderate physical activity (MPA), vigorous physical activity (VPA), and self-rated health (SRH) in the association between depression and quality of life (QoL) in a large sample of Europeans aged 50 and over, differentiated by sex. Methods: Data from the 2017 Survey of Health, Ageing and Retirement in Europe were analyzed, including 11,986 individuals (6843 women) aged 50 and older. All information was collected through face-to-face interviews: sociodemographic data, SRH, physical activity levels, depression (EURO-D scale), and QoL (CASP-12). Results: Comparatively, women reported a higher prevalence of depression, a lower perception of QoL, and slightly lower levels of SRH, MPA, and VPA. Parallel mediation models revealed, for both sexes, that an increase in VPA levels was more effective in benefiting SRH; and MPA proved to be a better promoter of QoL. When comparing sexes, only the path depression → VPA → QoL showed a significant difference (p < 0.001). Conclusions: These results provide valuable insights for developing physical activity interventions capable of improving mental health and promoting QoL in older European adults.

Evaluating the impact of rock climbing on mental health and emotional well-being in adolescents

Background

Rock climbing (RC) has gained attention as a therapeutic tool in psychiatric settings that merges physical exertion with mental engagement. It has potential to enhance mental health, through improved self-efficacy and social interaction, making it a novel intervention for addressing anxiety, depression, and behavioral issues in adolescents. This study aimed to investigate the effects of RC as a physical activity on anxiety, depression, and emotional and behavioral problems in adolescents.

Methods

The current study included 57 athletes aged 14.5 ± 1.7 years and 91 adolescents aged 13.6 ± 1.2 years, matched for age and gender, who were not professionally involved in sport. In addition to the socio-demographic form, a detailed psychiatric assessment was carried out by the child psychiatrist; using the Schedule for Affective Disorders and Schizophrenia for School-Age Children Present and Lifetime Version (K-SADS-PL) to detect psychiatric conditions. The Revised Child Anxiety and Depression Scale-Child Version (RCADS-CV) and the Strengths and Difficulties Questionnaire (SDQ) were also administered to the adolescents in the study.

Results

In the comparative analysis of the RCADS-CV outcomes between the athlete and control groups, the athletes demonstrated notably lower scores for both Separation Anxiety Disorder (SAD) and Generalized Anxiety Disorder (GAD), yielding p-values of < 0.001 and 0.031, respectively. Although the mean scores for social phobia, OCD, panic disorder, and MDD were lower in the athlete group, the differences were not statistically significant (p > 0.05). In the correlation analysis, a moderately significant correlation was found between the duration of doing sport and the scale scores for SAD (p:0.010), OCD (p:0.014), and panic disorder (p:0.016). There was no significant difference between groups in terms of SDQ scores.

Conclusion

These results suggest that RC, through its unique combination of physical exertion and mental focus, may offer protective benefits against certain anxiety disorders among adolescents. Further studies should be conducted to explore the potential use of RC as a preventive program for both healthy adolescents, as well as those with psychiatric disorder.
