Dietary habits and physical activity in first-episode psychosis patients treated in community services. Effect on early anthropometric and cardio-metabolic alterations

Abstract

People with psychosis often develop metabolic and cardiovascular disorders, due to several factors including unhealthy lifestyle and antipsychotic treatment. This study aims to evaluate in a sample of first episode psychosis (FEP) patients lifestyle factors, with a specific emphasis on dietary habits and physical activity, and cardio-metabolic and anthropometric profile at illness onset and at 9 months. Moreover, this study aims to evaluate the impact of lifestyle factors on short term changes in cardio-metabolic and anthropometric profile. A 9-month follow-up study was conducted on a sample of 96 FEP patients recruited within the context of the GET UP program. Standardised assessments of dietary habits (EPIC) and physical activity (IPAQ) were retrospectively performed at 9 months; cardiovascular measures (blood pressure, heart rate), metabolic parameters (glucose, cholesterol, triglycerides), BMI and antipsychotic treatment were assessed at illness onset and at 9 months. We found that most FEP patients (60%) displayed poor dietary habits, as defined in terms of adherence to the Mediterranean diet. A significant increase for both BMI and cholesterol levels was found in the overall sample over 9 months. However, when considering the effect of lifestyle factors, BMI and total cholesterol were specifically raised in patients with low adherence to Mediterranean diet. The association with antipsychotic medication was found for SGA only, with a significant increase in both BMI and total cholesterol overtime. Our findings confirm the need to implement specific and early strategies to promote healthy lifestyle in people with FEP, since metabolic alterations occur within the first months of treatment.
