【 摘 要 】

OBJECTIVE: To evaluate the effectiveness of a non-pharmacological intervention for weight gain management in severe mental disorders. METHOD: An open, multicentre interventional study was conducted in 93 mental health services. Patients concerned with weight gain were included in this study and received a 12-week 1-hour group intervention focused on nutrition counseling, lifestyle, physical activity and self-esteem. Weight, waist circumference and blood pressure were measured before and after the intervention. RESULTS: 1,071 patients were enrolled in the study, and 73.9% completed the 12-week intervention. Significant weight loss (Mean difference: 0.41, CI 95%: 0.18 to 0.64, p = 0.001) and a significant BMI reduction (Mean difference: 0.13, CI 95%: 0.04 to 0.22, p = 0.006) were observed. During the intervention 37 (4.4%) patients lost > 7% of their initial weight, 780 (92.5%) maintained their weight, and 26 (3.1%) of the patients had a meaningful weight gain (> 7%). There was a significant increase in the proportion of patients undertaking physical activity after the intervention (70.8%, p < 0.001). CONCLUSION: In this 3-month open study we found a small weight and waist reduction, and increased physical activity practice, suggesting a trend towards anthropometric profile improvement. However, further randomized-controlled trials are necessary to evaluate the efficacy and clinical relevance of this psychosocial intervention for weight gain.
