Diet, smoking and cardiovascular risk in people with schizophrenia

Abstract

Background Physical health of people with schizophrenia is poor and they die early from cardiovascular disease. Aims To describe the lifestyle of people with schizophrenia through diet, smoking habits, weight and exercise, and to report risk of coronary heart disease (CHD). Method Dietary habits of 102 community-dwelling people with schizophrenia were assessed by the Scottish Health Survey Questionnaire. Also assessed were smoking habits, physical activity biochemical indices of nutrition and future risk of CHD. Results Fewer males, compared with the general population, reached acceptable levels for consumption of fruit, vegetables, milk, potatoes and pulses. Fewer females reached the levels for consumption of milk and potatoes. Mean number of fruit and vegetable portions consumed per week was 16 (s.d.=14); 71 (70%) were smokers; 25 (86%) females and 50 (70%) males were overweight or obese; 59 (59%) considered themselves physically active; 46 (53%) had a raised cholesterol: high-density lipoprotein ratio, and 64 (74%) a low α-tocopherol: cholesterol ratio. Mean 10-year risk of CHD in males was 10.5% (s.d.=8) and in females 7% (s.d.=6). Conclusions The lifestyle of people with schizophrenia must give cause for concern in relation to CHD Care from secondary care services must address physical as well as mental health.
