Abstract
BackgroundPeople with severe mental illness (SMI) die earlier than the general population, primarily due to physical disorders. There is limited information on physical illnesses and health-risk behaviours in people with SMI in low and middle-income countries.MethodsWe conducted a cross-sectional survey in adults with SMI attending specialist mental health services in Bangladesh and Pakistan. Data were collected on non-communicable diseases (NCDs), their risk factors, health-risk behaviours, treatments and health risk modification advice (using questions from the WHO STEPwise approach to Surveillance of NCDs (STEPS)) and on common mental disorders, health-related quality of life and infectious diseases. We performed a descriptive analysis, and compared weighted prevalence for these variables in our survey with prevalence for the general population in the STEPS reports from Bangladesh and Pakistan.ResultsWe recruited 2,344 participants with bipolar disorder (36.7%), non-affective psychosis (42.2%), and depression with psychosis (21.1%). Eight percent had diabetes, 24.7% hypertension and 3.1% tuberculosis. 43.4% were overweight or obese, and half had hypercholesterolemia. Most participants with diabetes, hypertension and hypercholesterolemia were previously undiagnosed; of those diagnosed only around half were receiving treatment. Fifty-four percent of men and 17.2% of women used tobacco; 46.9% and 87.1% did not meet WHO recommendations for physical activity and fruit and vegetable intake respectively. Compared with the general population, people with SMI were more likely to have diabetes (O.R.=1.56,95%C.I.=1.30 to 1.88 Bangladesh), hypercholesterolemia (O.R.=2.35,95%C.I.=2.08 to 2.65 Bangladesh) and overweight or obesity (O.R.=1.97, 95%C.I.=1.75 to 2.22 Bangladesh; O.R.=1.61,95%C.I.=1.40 to 1.86 Pakistan). They were less likely to receive tobacco cessation (O.R.=0.33,95%C.I.=0.26 to 0.42 Bangladesh; O.R.=0.42,95%C.I.=0.31 to 0.55 Pakistan), and weight management advice (O.R.=0.51,95%C.I.=0.41 to 0.63 Bangladesh; and O.R.=0.65,95%C.I.=0.51 to 0.82 Pakistan).ConclusionDespite the high prevalence we found significant gaps in detection, prevention and treatment of NCDs and their risk factors in people with SMI.RegistrationISRCTN88485933; https://doi.org/10.1186/ISRCTN88485933
