Sedentary behavior and physical activity levels in people with schizophrenia, bipolar disorder and major depressive disorder: a global systematic review and meta-analysis

People with severe mental illness (schizophrenia, bipolar disorder or major depressive disorder) die up to 15 years prematurely due to chronic somatic comorbidities. Sedentary behavior and low physical activity are independent yet modifiable risk factors for cardiovascular disease and premature mortality in these people. A comprehensive meta‐analysis exploring these risk factors is lacking in this vulnerable population. We conducted a meta‐analysis investigating sedentary behavior and physical activity levels and their correlates in people with severe mental illness. Major electronic databases were searched from inception up to April 2017 for articles measuring sedentary behavior and/or physical activity with a self‐report questionnaire or an objective measure (e.g., accelerometer). Random effects meta‐analyses and meta‐regression analyses were conducted. Sixty‐nine studies were included (N=35,682; 39.5% male; mean age 43.0 years). People with severe mental illness spent on average 476.0 min per day (95% CI: 407.3‐545.4) being sedentary during waking hours, and were significantly more sedentary than age‐ and gender‐matched healthy controls (p=0.003). Their mean amount of moderate or vigorous physical activity was 38.4 min per day (95% CI: 32.0‐44.8), being significantly lower than that of healthy controls (p=0.002 for moderate activity, p<0.001 for vigorous activity). People with severe mental illness were significantly less likely than matched healthy controls to meet physical activity guidelines (odds ratio = 1.5; 95% CI: 1.1‐2.0, p<0.001, I2=95.8). Lower physical activity levels and non‐compliance with physical activity guidelines were associated with male gender, being single, unemployment, fewer years of education, higher body mass index, longer illness duration, antidepressant and antipsychotic medication use, lower cardiorespiratory fitness and a diagnosis of schizophrenia. People with bipolar disorder were the most physically active, yet spent most time being sedentary. Geographical differences were detected, and inpatients were more active than outpatients and those living in the community. Given the established health benefits of physical activity and its low levels in people with severe mental illness, future interventions specifically targeting the prevention of physical inactivity and sedentary behavior are warranted in this population.

Cardiorespiratory Fitness in Severe Mental Illness: A Systematic Review and Meta-analysis.

BackgroundCardiorespiratory fitness (CRF) among people with severe mental illness (SMI) (i.e., schizophrenia, bipolar disorder, and major depressive disorder) is a critical clinical risk factor given its relationship to cardiovascular disease and premature mortality.ObjectivesThis study aimed to: (1) investigate the mean CRF in people with SMI versus healthy controls; (2) explore moderators of CRF; and (3) investigate whether CRF improved with exercise interventions and establish if fitness improves more than body mass index following exercise interventions.MethodsMajor electronic databases were searched systematically. A meta-analysis calculating Hedges’ g statistic was undertaken.ResultsAcross 23 eligible studies, pooled mean CRF was 28.7 mL/kg/min [95 % confidence interval (CI) 27.3 to 30.0 mL/kg/min, p < 0.001, n = 980]. People with SMI had significantly lower CRF compared with controls (n = 310) (Hedges’ g = −1.01, 95 % CI −1.18 to −0.85, p < 0.001). There were no differences between diagnostic subgroups. In a multivariate regression, first-episode (β = 6.6, 95 % CI 0.6–12.6) and inpatient (β = 5.3, 95 % CI 1.6–9.0) status were significant predictors of higher CRF. Exercise improved CRF (Hedges’ g = 0.33, 95 % CI = 0.21–0.45, p = 0.001), but did not reduce body mass index. Higher CRF improvements were observed following interventions at high intensity, with higher frequency (at least three times per week) and supervised by qualified personnel (i.e., physiotherapists and exercise physiologists).ConclusionThe multidisciplinary treatment of people with SMI should include a focus on improving fitness to reduce all-cause mortality. Qualified healthcare professionals supporting people with SMI in maintaining an active lifestyle should be included as part of multidisciplinary teams in mental health treatment.

Physical activity and anxiety: A perspective from the World Health Survey

BACKGROUND Despite the known benefits of physical activity (PA) among people with anxiety, little is known about PA levels in people with anxiety at the population level. This study explored the global prevalence of anxiety and its association with PA. METHODS Cross-sectional, community-based data from the World Health Survey was analyzed. Prevalence of anxiety was estimated for 237,964 individuals (47 countries). PA was categorized as low, moderate, and high based on the International Physical Activity Questionnaire (short form). The association between PA and anxiety was assessed by multivariable logistic regression. RESULTS The overall global prevalence of anxiety was 11.4% (47 countries). Across 38 countries with available data on PA, 62.5%, 20.2%, and 17.3% of the sample engaged in high, moderate, and low levels of PA respectively. The prevalence of low physical activity in those with and without anxiety was 22.9% vs. 16.6% (p<0.001) (38 countries, n=184,920). In the pooled model adjusted for socio-demographics, depression, and country, individuals engaging in low PA (vs. high PA) had 1.32 (95% CI=1.17-1.47) times higher odds for anxiety than those with high PA. Female sex, older age, lower education and wealth, and depression were also associated with low PA. At the individual country level, there was a significant positive association between low PA and anxiety in 17 of the 38 countries. CONCLUSION Low PA levels are associated with increased prevalence of anxiety. There is a need for longitudinal research to establish the directionality of the relationships observed.

Physical activity and sedentary behavior in people with bipolar disorder: A systematic review and meta-analysis

BACKGROUND Mortality rates are approximately two to three times higher in people with bipolar disorder (BD) than in general population. Lack of physical activity (PA) and sedentary behavior (SB) are independent risk factors for cardiovascular disease and premature mortality. AIMS We conducted a meta-analysis to investigate PA and SB levels and its predictors in BD. METHODS Major electronic databases were searched from inception till 02/2016 for articles measuring PA and SB with a self-report questionnaire (SRQ) or objective measure (e.g. accelerometer) in BD. A random effects meta-analysis and meta-regression analysis were conducted. RESULTS Six studies were eligible including 279 (129♂) people with BD (mean age=43.9 years; range: 32.0-51.5 years). The trim and fill analysis demonstrated people with BD spent in total 210.1min (95%CI=146.3-273.9min) per day being physically active and 613.3min (95%CI=389.9-836.6min) during waking hours being sedentary. No significant difference in total PA per day was observed between people with BD and controls (g=-0.62, 95% CI=-1.55 to 0.31, I(2)=88.5%, n BD =82, n controls =86). Objective measures of PA recorded significantly lower levels (P=0.03) compared to self-report PA. Meta-regression demonstrated that older age and a higher body mass index predicted lower PA levels. LIMITATIONS Only a limited number of studies were identified assessing SB in people with BD. CONCLUSIONS Adults with BD engage in high levels of sedentary behavior during waking hours. Given that sedentary behavior is an independent predictor of cardiovascular disease, future lifestyle interventions specifically targeting the prevention of sedentary behavior are warranted.

Distancing: a traditional mechanism of dealing with suicide among the Baganda, Uganda.

This qualitative study investigated attitudes and cultural responses to suicide among the Baganda in Uganda using both focus group discussions and key-informant interviews. Interviews indicate that suicide is perceived as dangerous to the whole family and the entire community. Communities and family members adopt various ritual practices to distance themselves both symbolically and socially from the suicide. These rituals are characterized by broad themes: the regulation of affect and the attempt to secure future generations.

The epidemiology of back pain and its relationship with depression, psychosis, anxiety, sleep disturbances, and stress sensitivity: Data from 43 low- and middle-income countries

BACKGROUND Back pain (BP) is a leading cause of global disability. However, population-based studies investigating its impact on mental health outcomes are lacking, particularly among low- and middle-income countries (LMICs). Thus, the primary aims of this study were to: (1) determine the epidemiology of BP in 43 LMICs; (2) explore the relationship between BP and mental health (depression spectrum, psychosis spectrum, anxiety, sleep disturbances and stress). METHODS Data on 190,593 community-dwelling adults aged ≥18 years from the World Health Survey (WHS) 2002-2004 were analyzed. The presence of past-12 month psychotic symptoms and depression was established using questions from the Composite International Diagnostic Interview. Anxiety, sleep problems, stress sensitivity, and any BP or chronic BP (CBP) during the previous 30 days were also self-reported. Multivariable logistic regression analyses were undertaken. RESULTS The overall prevalence of any BP and CBP were 35.1% and 6.9% respectively. Significant associations with any BP were observed for subsyndromal depression [OR (odds ratio)=2.21], brief depressive episode (OR=2.64), depressive episode (OR=2.88), psychosis diagnosis with symptoms (OR=2.05), anxiety (OR=2.12), sleep disturbance (OR=2.37) and the continuous variable of stress sensitivity. Associations were generally more pronounced for chronic BP. CONCLUSION Our data establish that BP is associated with elevated mental health comorbidity in LMICs. Integrated interventions that address back pain and metal health comorbidities might be an important next step to tackle this considerable burden.

Physical activity and depression: a large cross-sectional, population-based study across 36 low- and middle-income countries

Physical activity (PA) is good for health, yet several small‐scale studies have suggested that depression is associated with low PA. A paucity of nationally representative studies investigating this relationship exists, particularly in low‐ and middle‐income countries (LMICs). This study explored the global association of PA with depression and its mediating factors.

Physical Activity Levels and Psychosis: A Mediation Analysis of Factors Influencing Physical Activity Target Achievement Among 204 186 People Across 46 Low- and Middle-Income Countries

Physical activity (PA) can help reduce cardiovascular disease and premature mortality in people with psychosis. However, there is a paucity of representative data on PA in people with psychosis, especially from low- and middle-income countries (LMICs). Moreover, data on subclinical psychosis and PA is absent. This study explored whether complying with PA recommendations of 150 minutes of moderate-vigorous PA per week is related to: (1) psychotic symptoms without a psychosis diagnosis (subclinical psychosis); and (2) clinical psychosis (psychosis diagnosis). A total of 204 186 participants aged 18-64 years from 46 LMICs recruited via the World Health Survey were subdivided into those with (1) no psychosis diagnosis and no psychotic symptoms in the past 12 months (controls); (2) subclinical psychosis; and (3) psychosis diagnosis. People with a psychosis diagnosis had significantly higher odds for low PA in the overall sample (OR = 1.36; 95% CI = 1.04-1.78; P = .024) and among males (OR = 2.29; 95% CI = 1.57-3.34; P < .0001) but not females (OR = 0.93; 95% CI = 0.67-1.30; P = .6712). No difference was found among those with subclinical psychosis vs controls. Mediation analyses demonstrated that mobility difficulties explained the largest amount of low PA among males (18.5%) followed by self-care difficulties (16.3%), depression (16.1%), cognition (11.8%), pain and discomfort (11.4%), interpersonal activities (8.6%), sleep and energy (7.2%), and vision (3.0%). The results from the largest dataset on PA and psychosis and first in LMICs, found that psychosis diagnosis (especially among males) but not subclinical psychosis, is associated with physical inactivity. Population level interventions seeking to increase PA among people with psychosis may help improve health outcomes.

Doing qualitative research on suicide in a developing country: practical and ethical challenges.

BACKGROUND This article describes and discusses the challenges faced by researchers who conducted a qualitative interview study on attitudes toward suicide among the Baganda, Uganda. Many of the challenges addressed in this article have not been described earlier in suicide research conducted in the developing world. AIMS The aim of this study was to explore attitudes and cultural responses toward suicide among the Baganda, Uganda. METHODS Data were collected and analyzed using grounded theory. A total of 28 focus group discussions and 30 key informant interviews were conducted. RESULTS The findings of this study are organized under two broad categories: community access challenges and expectation challenges. Community access challenges entailed cultural, legal, rapport, informed consent, language, and other research process related issues that could hinder effective access to the study respondents. Expectation challenges concerned how to deal with the immediate and strategic needs of the study communities. CONCLUSIONS This study demonstrates that culturally sensitive approaches to data collection can reduce ethical challenges and, through innovative approaches, practical challenges faced during data collection can be minimized.

Depression and physical health multimorbidity: Primary data and country-wide meta-analysis of population data from 190 593 people across 43 low- and middle-income countries

BACKGROUND Despite the known heightened risk and burden of various somatic diseases in people with depression, very little is known about physical health multimorbidity (i.e. two or more physical health co-morbidities) in individuals with depression. This study explored physical health multimorbidity in people with clinical depression, subsyndromal depression and brief depressive episode across 43 low- and middle-income countries (LMICs). METHOD Cross-sectional, community-based data on 190 593 individuals from 43 LMICs recruited via the World Health Survey were analysed. Multivariable logistic regression analysis was done to assess the association between depression and physical multimorbidity. RESULTS Overall, two, three and four or more physical health conditions were present in 7.4, 2.4 and 0.9% of non-depressive individuals compared with 17.7, 9.1 and 4.9% among people with any depressive episode, respectively. Compared with those with no depression, subsyndromal depression, brief depressive episode and depressive episode were significantly associated with 2.62, 2.14 and 3.44 times higher odds for multimorbidity, respectively. A significant positive association between multimorbidity and any depression was observed across 42 of the 43 countries, with particularly high odds ratios (ORs) in China (OR 8.84), Laos (OR 5.08), Ethiopia (OR 4.99), the Philippines (OR 4.81) and Malaysia (OR 4.58). The pooled OR for multimorbidity and depression estimated by meta-analysis across 43 countries was 3.26 (95% confident interval 2.98-3.57). CONCLUSIONS Our large multinational study demonstrates that physical health multimorbidity is increased across the depression spectrum. Public health interventions are required to address this global health problem.
