(Springer Link: International Journal of Behavioral Nutrition and Physical Activity., 2017-01-18) Vancampfort, Davy; Koyanagi, Ai; Ward, Philip B.; Rosenbaum, Simon; Schuch, Felipe B.; Mugisha, James; Richards, Justin; Firth, Joseph; Stubbs, Brendon
There are no nationally representative population-based studies investigating the relationship between physical activity, chronic conditions and multimorbidity (i.e., two or more chronic conditions) in low- and middle-income countries (LMICs), and studies on a multi-national level are lacking. This is an important research gap, given the rapid increase in the prevalence of chronic diseases associated with lifestyle changes in these countries. This cross-sectional study aimed to assess the association between chronic conditions, multimorbidity and low physical activity (PA) among community-dwelling adults in 46 LMICs, and explore the mediators of these relationships. Methods World Health Survey data included 228,024 adults aged ≥18 years from 46 LMICs. PA was assessed by the International Physical Activity Questionnaire (IPAQ). Nine chronic physical conditions (chronic back pain, angina, arthritis, asthma, diabetes, hearing problems, tuberculosis, visual impairment and edentulism) were assessed. Multivariable logistic regression and mediation analyses were used to assess the association between chronic conditions or multimorbidity and low PA. Results Overall, in the multivariable analysis, arthritis (OR = 1.12), asthma (1.19), diabetes (OR = 1.33), edentulism (OR = 1.46), hearing problems (OR = 1.90), tuberculosis (OR = 1.24), visual impairment (OR = 2.29), multimorbidity (OR = 1.31; 95% CI = 1.21–1.42) were significantly associated with low PA. More significant associations were observed in individuals aged ≥50 years. In older adults, depression mediated between 5.1% (visual impairment) to 23.5% (angina) of the association between a chronic condition and low PA. Mobility difficulties explained more than 25% of the association for seven of the eight chronic conditions. Pain was a strong mediator for angina (65.9%) and arthritis (64.9%), while sleep problems mediated up to 43.7% (angina) of the association. Conclusions In LMICs, those with chronic conditions and multimorbidity are significantly less physically active (especially older adults). Research on the efficacy and effectiveness of PA in the management of chronic diseases in LMICs is urgently needed. Targeted promotion of physical activity to populations in LMICs experiencing chronic conditions may ameliorate associated depression, mobility difficulties and pain that are themselves important barriers for initiating or adopting an active lifestyle.

(Cambridge University Press: International Psychogeriatrics, 2017-11-08) Vancampfort, Davy; Stubbs, Brendon; Hallgren, Mats; Veronese, Nicola; Mugisha, James; Probst, Michel; Koyanagi, Ai
Given the important health benefits of physical activity (PA) and the higher risk for physical inactivity in people with anxiety, and the high prevalence of anxiety and low PA among the elderly, there is a need for research to investigate what factors influence PA participation among anxious older individuals. We investigated PA correlates among community-dwelling adults aged ≥ 65 years with anxiety symptoms 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. PA level was assessed by the Global Physical Activity Questionnaire. 980 participants with anxiety (mean age 73.3 years; 62.4% females) were grouped into those who do and do not (low PA) meet the 150 minutes of moderate-to-vigorous PA per week recommendation. Associations between PA and the correlates were examined using multivariable logistic regressions. Results: The prevalence of low PA was 44.9% (95% CI = 39.2–50.7%). Older age, male gender, less consumption of alcohol, mild cognitive impairment, pain, a wide range of somatic co-morbidities, slow gait, weak grip strength, poor self-rated health, and lower levels of social cohesion were identified as significant positive correlates of low PA. Conclusions: Our data illustrate that a number of sociodemographic and health factors are associated with PA levels among older people with symptoms of anxiety. The promotion of social cohesion may increase the efficacy of public health initiatives, while from a clinical perspective, somatic co-morbidities, cognitive impairment, pain, muscle strength, and slow gait need to be considered.
Correlates of physical activity among depressed older people in six low-income and middle-income countries: a community-based cross-sectional study
(Wiley Online Library: International Journal of Geriatric Psychiatry, 2017-10-10) Vancampfort, Davy; Stubbs, Brendon; Veronese, Nicola; Mugisha, James; Swinnen, Nathalie; Koyanagi, Ai
Despite the benefits of physical activity (PA) in older people with depression, many do not comply with the International PA guidelines. Thus, we investigated what factors influence PA participation among 915 community-dwelling older adults (aged ≥65 years) with depression in 6 low-income and middle-income countries (LMICs). Methods Cross-sectional data were analyzed from the World Health Organization's Study on Global Ageing and Adult Health. The sample was restricted to those with DSM-IV depression or receiving depression treatment in the last 12 months. PA was assessed by the Global Physical Activity Questionnaire. Participants were dichotomized into low (ie, not meeting 150 minutes of moderate PA per week) and moderate-to-high physically active groups. Associations between PA and a range of correlates were examined using multivariable logistic regressions. Results The prevalence of low PA was 40.4% (95%CI = 34.8%–46.1%). After adjusting for age, sex, and country, larger household size and unemployment were significant sociodemographic correlates of low PA. Former smoking (vs never), anxiety, mild cognitive impairment (MCI), lower body mass index, bodily pain, asthma, chronic back pain, chronic obstructive pulmonary disease, hearing problems, stroke, slow gait, poor self-rated health, higher levels of disability, and lower levels of social cohesion were identified as significant negative correlates of PA. Conclusions The current data provide guidance for future interventions across LMICs to assist older people with depression engage in regular PA. The promotion of social cohesion may increase the efficacy of future public health initiatives, while from a clinical perspective, somatic co-morbidities, MCI, pain, and slow gait need to be considered.
Correlates of physical activity among middle-aged and older adults with hazardous drinking habits in six low- and middle-income countries
(Kinetic: Aging and Physical Activity, 2017) Vancampfort, Davy; Stubbs, Brendon; Hallgren, Mats; Lundin, Andreas; Mugisha, James; Koyanagi, Ai
We investigated physical activity (PA) correlates among middle-aged and older adults (aged ≥50 years) with hazardous drinking patterns in six low- and middle-income countries. Cross-sectional data were analyzed from the World Health Organization’s Study on Global Ageing and Adult Health. Hazardous drinking was defined as consuming >7 (females) or >14 (males) standard drinks per week. Participants were dichotomized into low (i.e., not meeting 150 min of moderate PA/week) and moderate–high physically active groups. Associations between PA and a range of correlates were examined using multivariable logistic regressions. The prevalence of low PA in 1,835 hazardous drinkers (60.5 ± 13.1 years; 87.9% males) was 16.2% (95% confidence interval [13.9%, 18.9%]). Older age, living in an urban setting, being unemployed, depression, underweight, obesity, asthma, visual impairment, poor self-rated health, and higher levels of disability were identified as significant PA correlates. The current data provide important guidance for future interventions to assist older hazardous drinkers to engage in regular PA.

(Elsevier : Journal of effective Disorders., 2018-07) Vancampfort, Davy; Stubbs, Brendon; Mugisha, James; Firth, Joseph; Schuch, Felipe B.; Koyanagi, Ai
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.
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
(Elsevier: General Hospital Psychiatry, 2016-12) Stubbs, Brendon; Koyanagi, Ai; Thompson, Trevor; Veronese, Nicola; Carvalho, Andre F.; Solomi, Marco; Mugisha, James; Schofield, Patricia; Cosco, Theodore; Wilson, Nicky; Vancampfort, Davy
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.
Leisure-time sedentary behavior and suicide attempt among 126,392 adolescents in 43 countries
(Elsevier: Journal of Affective Disorders, 2019-05-01) Vancampfort, Davy; Stubbs, Brendon; Mugisha, James; Firth, Joseph; Van Damme, Tine; Smith, Lee; Koyanagi, Ai
Adolescent suicide is a major global mental health problem. Exploring variables associated with suicide attempts is important for the development of targeted interventions. The aim of the current study was to explore associations between leisure-time sedentary behavior and suicide attempts. Methods Data from the Global School-based Student Health Survey were analyzed. Data on past 12-month suicide attempts and self-reported leisure-time sedentary time were collected. Multivariable logistic regression and meta-analysis were conducted to assess the associations. Results Among 126,392 students from 43 countries (mean age 13.8 ± 0.96 years; 48.9% female), 10.6% had attempted suicide. The prevalence of suicide attempts increased with increasing sedentary leisure-time per day (from 9% at <1 h/day to 16.8% at >8 h/day). Compared to those engaging in <1 h/day sedentary during leisure-time, there was a dose-dependent increase in odds ratios (ORs) for suicide attempts, with the OR for >8 h/day being 1.45 (95% confidence interval=1.19–1.77). Limitations The study is cross-sectional, therefore the directionality of the relationships cannot be deduced. Conclusions Our data suggest that leisure-time sedentary behavior is associated with increased odds for suicide attempt in adolescence. Future longitudinal data are required to confirm/refute the findings to inform public prevention campaigns.
Pain and severe sleep disturbance in the general population: primary data and meta-analysis from 240,820 people across 45 low- and middle-income countries
(Elsevier: General Hospital Psychiatry, 2018-08) Stubbs, Brendon; Vancampfort, Davy; Thompson, Trevor; Veronese, Nicola; Carvalho, Andre F.; Solmi, Marco; Mugisha, James; Schofield, Patricia; Prina, A.Matthew; Smith, Lee; Koyanagi, Ai
Pain and sleep disturbances are widespread, and are an important cause of a reduced quality of life. Despite this, there is a paucity of multinational population data assessing the association between pain and sleep problems, particularly among low- and middle-income countries (LMICs). Therefore, we investigated the relationship between pain and severe sleep disturbance across 45 LMICs. Method Community-based data on 240,820 people recruited via the World Health Survey were analyzed. Multivariable logistic regression analyses adjusted for multiple confounders were performed to quantify the association between pain and severe sleep problems in the last 30 days. A mediation analysis was conducted to explore potential mediators of the relationship between pain and severe sleep disturbance. Results The prevalence of mild, moderate, severe, and extreme levels of pain was 26.0%, 16.2%, 9.1%, and 2.2% respectively, whilst 7.8% of adults had severe sleep problems. Compared to those with no pain, the odds ratio (OR, 95% CI) for severe sleep problems was 3.65 (3.24–4.11), 9.35 (8.19–10.67) and 16.84 (13.91–20.39) for those with moderate, severe and extreme pain levels respectively. A country wide meta-analysis adjusted for age and sex demonstrated a significant increased OR across all 45 countries. Anxiety, depression and stress sensitivity explained 12.9%, 3.6%, and 5.2%, respectively, of the relationship between pain and severe sleep disturbances. Conclusion Pain and sleep problems are highly co-morbid across LMICs. Future research is required to better understand this relationship. Moreover, future interventions are required to prevent and manage the pain and sleep disturbance comorbidity.
Physical activity and anxiety: a perspective from the World Health Survey
(Elsevier: Journal of Affective Disorders ., 2017-01-15) Stubbs, Brendon; Koyanagi, Ai; Hallgren, Mats; Firth, Joseph; Richards, Justin; Schuch, Felipe; Rosenbaum, Simon; Mugisha, James; Veronese, Nicola; Lahti, Jouni; Vancampfort, Davy
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 correlates among 24,230 people with depression across 46 low- and middle-income countries
(Elsevier: Journal of Affective Disorders, 2017-10-15) Vancampfort, Davy; Stubbs, Brendon; Firth, Joseph; Hallgren, Mats; Schuch, Felipe; Lahti, Jouni; Rosenbaum, Simon; Ward, Philip B.; Mugisha, James; Carvalho, André F.; Koyanagi, Ai
There is a paucity of nationally representative data available on the correlates of physical activity (PA) among people with depression, especially in low- and middle-income countries (LMICs). Thus, we investigated PA correlates among community-dwelling adults with depression in this setting. Methods World Health Survey data included 24,230 adults (43.1 ± 16.1 years; 36.1% male) with ICD-10 diagnoses of depression including brief depressive episode and subsyndromal depression aged ≥ 18 years from 46 LMICs. PA was assessed by the International Physical Activity Questionnaire. Participants were dichotomised into low and moderate-to-high physically active groups. Associations between PA and a range of sociodemographic, health behaviour and mental and physical health variables were examined using multivariable logistic regressions. Results 34.8% of participants with depression were physically inactive. In the multivariate analyses, inactivity was associated with male sex, older age, not being married/cohabiting, high socio-economic status, unemployment, living in an urban setting, less vegetable consumption, and poor sleep/ low energy. In addition, mobility difficulties and some somatic co-morbidity were associated with not complying with the 150 min per week moderate-to-vigorous PA recommendations. Conclusions The current data provide guidance for future population level interventions across LMICs to help people with depression engage in regular PA.
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
(Schizophrenia Bulletin: The Journal of Psychoses and Related Disorders., 2016-08-24) Stubbs, Brendon; Koyanagi, Ai; Schuch, Felipe; Firth, Joseph; Rosenbaum, Simon; Gaughran, Fiona; Mugisha, James; Vancampfort, Davy
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.
Physical multimorbidity and psychosis: comprehensive cross sectional analysis including 242,952 people across 48 low- and middle-income countries
(BMC Medicine, 2016-11-22) Stubbs, Brendon; Koyanagi, Ai; Veronese, Nicola; Vancampfort, Davy; Solmi, Marco; Gaughran, Fiona; Carvalho, André F.; Lally, John; Mitchell, Alex J.; Mugisha, James; Correll, Christoph U.
: In people with psychosis, physical comorbidities, including cardiovascular and metabolic diseases, are highly prevalent and leading contributors to the premature mortality encountered. However, little is known about physical health multimorbidity in this population or in people with subclinical psychosis and in low- and middle-income countries (LMICs). This study explores physical health multimorbidity patterns among people with psychosis or subclinical psychosis. Methods: Overall, data from 242,952 individuals from 48 LMICs, recruited via the World Health Survey, were included in this cross-sectional study. Participants were subdivided into those (1) with a lifetime diagnosis of psychosis (“psychosis”); (2) with more than one psychotic symptom in the past 12 months, but no lifetime diagnosis of psychosis (“subclinical psychosis”); and (3) without psychotic symptoms in the past 12 months or a lifetime diagnosis of psychosis (“controls”). Nine operationalized somatic disorders were examined: arthritis, angina pectoris, asthma, diabetes, chronic back pain, visual impairment, hearing problems, edentulism, and tuberculosis. The association between psychosis and multimorbidity was assessed by multivariable logistic regression analysis. Results: The prevalence of multimorbidity (i.e., two or more physical health conditions) was: controls = 11.4% (95% CI, 11.0–11.8%); subclinical psychosis = 21.8% (95% CI, 20.6–23.0%), and psychosis = 36.0% (95% CI, 32.1–40. 2%) (P < 0.0001). After adjustment for age, sex, education, country-wise wealth, and country, subclinical psychosis and psychosis were associated with 2.20 (95% CI, 2.02–2.39) and 4.05 (95% CI, 3.25–5.04) times higher odds for multimorbidity. Moreover, multimorbidity was increased in subclinical and established psychosis in all age ranges (18–44, 45–64, ≥ 65 years). However, multimorbidity was most evident in younger age groups, with people aged 18–44 years with psychosis at greatest odds of physical health multimorbidity (OR = 4.68; 95% CI, 3.46–6.32).(Continued from previous page) Conclusions: This large multinational study demonstrates that physical health multimorbidity is increased across the psychosis-spectrum. Most notably, the association between multimorbidity and psychosis was stronger among younger adults, thus adding further impetus to the calls for the early intervention efforts to prevent the burden of physical health comorbidity at later stages. Urgent public health interventions are necessary not only for those with a psychosis diagnosis, but also for subclinical psychosis to address this considerable public health problem.
Sedentary behavior and anxiety-induced sleep disturbance among 181,093 adolescents from 67 countries: a global perspective
(Elsevier: Sleep Medicine, 2019-06) Vancampfort, Davy; Van Damme, Tine; Stubbs, Brendon; Smith, Lee; Firth, Joseph; Hallgren, Mats; Mugisha, James; Koyanagi, Ai
Sleep problems are burdensome in adolescents. Understanding modifiable environmental risk factors is essential. There is evidence that physical activity is protective against sleep problems in adolescents. However, the association between sedentary behavior (SB) and anxiety-induced sleep disturbance has not been investigated. Methods Using cross-sectional data from the Global school-based Student Health Survey, we explored the association between SB and anxiety-induced sleep disturbance in 181,093 adolescents [mean (standard deviation, SD) age 13.7 (1.0) years; 48.4% girls] from 67 countries, controlling for confounders (including physical activity). Adolescents reported anxiety-induced sleep disturbance during the past 12 months, and SB, which was a composite variable assessing time spent sitting and watching television, playing computer games, talking with friends during a typical day excluding the hours spent sitting at school and doing homework. Multivariable logistic regression analysis was conducted and a countrywide meta-analysis undertaken. Results Overall, 7.8% of adolescents had anxiety-induced sleep disturbance. The prevalence of SB was: <1 h/day 39.9%; 1–2 h/day 33.8%; 3–4 h/day 15.4%; 5–8 h/day 7.4%; and >8 h/day 3.6%. Compared to <1 h/day of SB, >8 h/day was associated with a 2.27 [95% confidence interval (CI) = 1.98–2.62] times higher odds for anxiety-induced sleep disturbance. The association was similar among both sexes. The pooled odds ratio for anxiety-induced sleep disturbance when being sedentary ≥3 h/day was 1.42 (95% CI = 1.36–1.48) with only a small degree of between-country heterogeneity (I2 = 41.4%). Conclusions Future longitudinal data are required to confirm/refute the findings to inform public interventions which aim to reduce anxiety and sleep disturbance in adolescents.
