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 physical activity levels in people with schizophrenia, bipolar disorder and major depressive disorder: a global systematic review and meta-analysis
(World Psychiatry:Official Journal of the World Psychiatric Association(WPA)., 2017-10) Vancampfort, Davy; Firth, Joseph; Schuch, Felipe B.; Rosenbaum, Simon; Mugisha, James; Hallgren, Mats; Probst, Michel; Ward, Philip B.; Gaughran, Fiona; De Hert, Marc; Carvalho, André F.; Stubbs, Brendon
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.
