RESUMO
BACKGROUND: To our knowledge, only few studies have analyzed the relationship between meeting the 24-h movement guidelines and suicidality in adolescents. The aim of this study was twofold: first, to examine the association between meeting the 24-h movement recommendations and suicidal ideation, suicide planning, and attempted suicide in a representative sample of adolescents from the U.S.; and second, to test whether age group, sex, or race moderate these associations. METHOD: This is a cross-sectional study including pooled data from the 2011, 2013, 2015, 2017, 2019, and 2021 high school Youth Risk Behavior Surveys (YRBS). A total sample of 44,734 participants (48.5 % females) was included. The recommendations of the 24-h movement guidelines included physical activity, screen time, and sleep duration. Suicidality was examined considering three suicide-related behaviors: suicidal ideation (yes/no), suicide planning (yes/no), and attempted suicide (at least one time or more during the past 12 months). RESULTS: Adolescents who met all three recommendations showed a lower likelihood of suicidal ideation (odds ratio [OR] = 0.49, 95 % confidence interval [CI] 0.37 to 0.64, p < 0.001), suicide planning (OR = 0.51, 95 % CI 0.37 to 0.68, p < 0.001), and attempted suicide (OR = 0.66, 95 % CI 0.44 to 0.96, p = 0.038) than those who did not meet all the recommendations. Overall, when younger adolescents, female adolescents, and adolescents of minority races met the 24-h movement recommendations, they had lower odds of suicide-related outcomes than when they did not. LIMITATIONS: This is a cross-sectional study using self-reported data. It is not possible to establish cause-and-effect relationships, and the results could be influenced by some biases. CONCLUSION: This study suggests that meeting the 24-h movement recommendations could play a relevant role in the prevention of suicidal ideation, planning suicide, and attempted suicide in a nationwide sample from the U.S. adolescents.

BACKGROUND: Several tests are available to assess the different components of physical fitness, including cardiorespiratory fitness, muscular strength, and flexibility. However, the reliability and validity of physical fitness tests in people with mental disorders has not been meta-analyzed. AIMS: To examine the reliability, concurrent, and convergent validity of physical fitness tests in people with mental disorders. METHODS: Studies evaluating the reliability, concurrent, and convergent validity of physical fitness tests in people with mental disorders were searched from major databases until January 20, 2020. Random-effects meta-analyses were performed pooling (1) reliability: test-retest correlations at two-time points, (2) convergent validity between submaximal tests and maximal protocols, or (3) concurrent validity between two submaximal tests. Associations are presented using r values and 95% confidence intervals. Methodological quality was assessed using the Quality Appraisal of Reliability Studies and the Critical Appraisal Tool. RESULTS: A total of 11 studies (N = 504; 34% females) were included. Reliability of the fitness tests, produced r values ranging from moderate (balance test-EUROFIT; [r = 0.75 (0.60-0.85); p = 0.0001]) to very strong (explosive leg power EUROFIT; [r = 0.96 (0.93-0.97); p = 0.0001]). Convergent validity between the 6-min walk test (6MWT) and submaximal cardiorespiratory tests was moderate (0.57 [0.26-0.77]; p = 0.0001). Concurrent validity between the 2-min walk test and 6MWT (r = 0.86 [0.39-0.97]; p = 0.0004) was strong. CONCLUSION: The present study demonstrates that physical fitness tests are reliable and valid in people with mental disorders.

Background Higher cardiorespiratory fitness (CRF) is associated with lower depressive symptoms in adults. However, no systematic review with meta-analysis assessed the cross-sectional associations between CRF and depressive symptoms in children and adolescents. Therefore, this meta-analysis assessed the relationship between CRF and depressive symptom in these populations. Methods Cross-sectional data evaluating the correlation between CRF and depression were searched, from database inception through 21/05/2020, on PubMed, PsycINFO, Web of Science, and SPORTDiscus. Age, sex, CRF and depression assessments, and correlations were extracted. A random-effects meta-analysis was conducted, and the potential sources of heterogeneity were also explored through meta-regression analysis. Results Across 14 effects of 11 unique studies, including a total of 7,095 participants (median age=12.49) with nearly equal sex distribution (median=53% females), it was found that higher CRF was associated with lower depressive symptoms in children and adolescents (r =-0.174, 95%CI -0.221 to -0.126, p<0.001, I2=75.09, Q value=52.19). No moderators were identified. Conclusion Available evidence supports the notion that higher CRF is inversely associated with depressive symptoms in children and adolescents. Physical activity and exercise interventions targeting improving CRF should be promoted for these populations. Further studies, including clinical populations, should be conducted to assess objective measures of aerobic fitness and body composition, while controlling for puberty status, to better characterize this association.

BACKGROUND: Relatively few studies have assessed the prevalence, correlates, and independent impact on quality of life (QoL) of trichotillomania (TTM) in large samples. METHODS: Consecutive participants (N = 7639) were recruited from a cross-sectional web-based study. Sociodemographic data were collected and several validated self-reported mental health measures were completed (Minnesota Impulsive Disorders Interview, Hypomania checklist, Fagerström Test for Nicotine Dependence, Alcohol Use Disorders Identification Test, Early Trauma Inventory Self Report-Short Form, and the Symptom Checklist-90-Revised Inventory). Health-related QoL was assessed with the World Health Organization QoL abbreviated scale (WHOQOL-Bref). Multivariable models adjusted associations to potential confounders. RESULTS: The sample was predominantly composed of young females (71.3%; mean age: 27.2 ± 7.9 years). The prevalence of probable TTM was 1.4% (95% confidence intervals [CI]: 1.2-1.7), and was more common among females. Participants with probable TTM had a greater likelihood of having co-occurring probable depression (adjusted odds ratio [ORadj] = 1.744; 95% CI: 1.187-2.560), tobacco (ORadj = 2.250; 95% CI: 1.191-4.250), and alcohol (ORadj = 1.751; 95% CI: 1.169-2.621) use disorders. Probable TTM was also independently associated with suicidal ideation (ORadj = 1.917; 95% CI: 1.224-3.003) and exposure to childhood sexual abuse (ORadj = 1.221; 95% CI: 1.098-1.358). In addition, a positive screen for TTM had more impaired physical and mental QoL. CONCLUSIONS: TTM was associated with a positive screen for several psychiatric comorbidities as well as impaired physical and psychological QoL. Efforts towards the recognition and treatment of TTM across psycho-dermatology services are warranted.

This is a cross-sectional study evaluating the associations of self-reported moderate to vigorous physical activity, and sedentary behavior with depressive, anxiety, and co-occurring depressive and anxiety symptoms (D&A) in self-isolating Brazilians during the COVID-19 pandemic. Depressive and anxiety symptoms were collected using the Beck Depression and Anxiety Inventories (BDI and BAI). Among the 937 participants (females=72.3%), those performing ≥30 min/day of moderate to vigorous or ≥15 min/day of vigorous physical activity had lower odds of prevalent depressive, anxiety, and co-occurring D&A symptoms. Those spending ≥10 h/day sedentary were more likely to have depressive symptoms.

BACKGROUND: Prospective cohorts have suggested that physical activity (PA) can decrease the risk of incident anxiety. However, no meta-analysis has been conducted. AIMS: To examine the prospective relationship between PA and incident anxiety and explore potential moderators. METHODS: Searches were conducted on major databases from inception to October 10, 2018 for prospective studies (at least 1 year of follow-up) that calculated the odds ratio (OR) of incident anxiety in people with high PA against people with low PA. Methodological quality was assessed using the Newcastle-Ottawa Scale (NOS). A random-effects meta-analysis was conducted and heterogeneity was explored using subgroup and meta-regression analysis. RESULTS: Across 14 cohorts of 13 unique prospective studies (N = 75,831, median males = 50.1%) followed for 357,424 person-years, people with high self-reported PA (versus low PA) were at reduced odds of developing anxiety (adjusted odds ratio [AOR] = 0.74; 95% confidence level [95% CI] = 0.62, 0.88; crude OR = 0.80; 95% CI = 0.69, 0.92). High self-reported PA was protective against the emergence of agoraphobia (AOR = 0.42; 95% CI = 0.18, 0.98) and posttraumatic stress disorder (AOR = 0.57; 95% CI = 0.39, 0.85). The protective effects for anxiety were evident in Asia (AOR = 0.31; 95% CI = 0.10, 0.96) and Europe (AOR = 0.82; 95% CI = 0.69, 0.97); for children/adolescents (AOR = 0.52; 95% CI = 0.29, 0.90) and adults (AOR = 0.81; 95% CI = 0.69, 0.95). Results remained robust when adjusting for confounding factors. Overall study quality was moderate to high (mean NOS = 6.7 out of 9). CONCLUSION: Evidence supports the notion that self-reported PA can confer protection against the emergence of anxiety regardless of demographic factors. In particular, higher PA levels protects from agoraphobia and posttraumatic disorder.

OBJECTIVES: A number of small-scale, single-country studies have suggested that muscular weakness may be a biomarker for cognitive health, mild cognitive impairment (MCI), and dementia. However, multinational, representative studies are lacking, particularly from low- and middle-income countries (LMICs). Thus, we assessed the association between muscular strength (measured by maximal handgrip) and MCI in six LMICs (China, Ghana, India, Mexico, Russia, and South Africa), using nationally representative data. METHODS: Cross-sectional, community-based data on individuals aged 50 years or older from the World Health Organization's Study on Global Ageing and Adult Health were analyzed. MCI was defined according to the National Institute on Aging-Alzheimer's Association criteria. Weak handgrip strength was defined as less than 30 kg for men and less than 20 kg for women using the average value of two handgrip measurements of the dominant hand. Multivariable logistic regression analysis was conducted to assess the association between muscular strength and MCI. RESULTS: A total of 32 715 participants were included (mean age 62 ± SD 15.6 y and 51.7% female). The prevalence of MCI and weak handgrip strength was 15.3% (95% CI, 14.4%-16.3%) and 46.5% (95% CI, 43.6%-49.5%), respectively. After adjustment for potential confounders, weak handgrip strength was associated with 1.41 (95% CI, 1.23-1.61) times higher odds for MCI. The corresponding figures for those aged 50 to 64 years and 65 years or older were 1.35 (95% CI, 1.14-1.60) and 1.54 (95% CI, 1.27-1.86), respectively. CONCLUSIONS: Muscular weakness may provide a clinically useful indicator of MCI risk. Increasing our understanding of the connection between muscular and cognitive function could ultimately lead to the development and broader implementation of resistance training interventions targeting both physical and cognitive health.

INTRODUCTION: Handgrip strength is a simple and inexpensive marker of health and mortality risk. It presents an ideal risk-stratifying method for use in low and middle-income countries (LMICs). There are, however, no population-based studies investigating the associations between handgrip strength and depression in LMICs. We aimed to assess these associations among community-dwelling middle-aged and older adults using nationally representative data from six LMICs. METHOD: Cross-sectional data on individuals agedâ¯≥â¯50 years from the World Health Organization's Study on Global Ageing and Adult Health were analyzed. Depression was based on the Composite International Diagnostic Interview. Weak handgrip strength was defined asâ¯<â¯30â¯kg for men andâ¯<â¯20â¯kg for women using the average value of two handgrip measurements of the dominant hand. Multivariable logistic regression analysis was conducted. RESULTS: The sample included 34,129 individuals (62.4⯱â¯16.0 years; 52.1% female). The prevalence of weak handgrip strength and depression were 47.4% and 6.2%, respectively. Individuals with weak handgrip strength had a higher prevalence of depression than those without this condition (8.8% vs. 3.8%; pâ¯<â¯0.001). Across all countries, after adjustment for potential confounders, weak handgrip strength was associated with a 1.45 (95%CIâ¯=â¯1.12-1.88) times higher odds for depression, although some between-country differences were noted. DISCUSSION: Weaker handgrip strength is associated with higher odds for depression in LMICs. Future research should seek to establish the predictive value of this inexpensive measure for clinical use. Furthermore, interventional studies should examine if muscular strength can be a target of resistance-training interventions to address depressive symptoms in low-resourced settings.

OBJECTIVE: Sedentary behaviour (SB) is harmful for health and well-being and may be associated with depression. However, little is known about the correlates of SB in people with depression. Thus, we investigated SB correlates among community-dwelling adults with depression in six low- and middle-income countries. METHODS: Cross-sectional data from the World Health Organization's Study on Global Ageing and Adult Health were analyzed. The analysis was restricted to those with DSM-IV Depression or receiving depression treatment in the last 12 months. Self-reported time spent sedentary per day was the outcome. High SB was defined as ≥8 hours of SB per day. The correlates (sociodemographic and health-related) of SB were estimated by multivariable linear and logistic regression analyses. RESULTS: In 2375 individuals with depression (mean age=48.0 years; 60.7% female), the prevalence of high SB was 11.1% (95%CI=8.2%-14.9%), while the mean (±SD) time spent sedentary was 215 (±192) minutes per day. Socio-demographic factors significantly associated with high SB were older age and being unmarried, being male and being unemployed. In other domains, no alcohol consumption, current smoking, mild cognitive impairment, bodily pain, arthritis, stroke, disability, and lower levels of social cohesion, COPD, visual impairment, and poor self-rated health was associated with greater time spent sedentary. CONCLUSION: Our data suggest that future interventions seeking to reduce SB among individuals with depression may target at risk groups based on identified sociodemographic correlates while the promotion of social cohesion may have the potential to increase the efficacy of future public health initiatives. From a clinical perspective, bodily pain and somatic co-morbidities need to be taken into account.
