Weight maintenance following the STRIDE lifestyle intervention for individuals taking antipsychotic medications
Abstract
Individuals taking antipsychotic medications have increased risk of obesity-related early morbidity/mortality. This report presents weight maintenance results from a successful weight loss and behavioral lifestyle change program developed for people taking antipsychotic medications. STRIDE was a two-arm randomized controlled trial. Intervention participants attended weekly group meetings for 6 months, then monthly group meetings for 6 months. Assessments were completed at baseline and at 6, 12, and 24 months. At 24 months, intervention participants lost 3.7% of baseline weight and control participants 2.1%, a non-significant difference. Fasting glucose results followed a similar pattern. There was a statistically significant difference, however, for fasting insulin-the intervention group's levels decreased between the end of the intensive intervention (at 6 months) and 24 months (10.1-7.91 μU/mL); control participants' levels increased (11.66 to 12.92 μU/mL) during this period. There were also fewer medical hospitalizations among intervention participants (5.7%) than controls (21.1%; χ(2) = 8.47, P = 0.004) during the 12- to 24-month post-intervention maintenance period. Weight change differences between arms diminished followi...Continue Reading
