HealthDay News -- For patients with type 2 diabetes, lifestyle-based weight loss intervention trials achieve modest reductions in weight and glycated hemoglobin (HbA1c) levels, results of a meta-analysis published in Diabetes, Obesity, and Metabolism indicate.

To evaluate the effectiveness of lifestyle-based weight loss in adults with type 2 diabetes, Caroline O. Terranova, MPH, of the University of Queensland in Brisbane, Australia, and colleagues conducted a systematic review and meta-analysis. Included studies were randomized controlled trials evaluating weight loss interventions (diet and physical activity, with or without behavioral strategies) of ≥12 weeks duration versus usual care or another comparison intervention.

From six studies comparing lifestyle intervention with usual care, the researchers found the pooled effect on weight (5,795 patients) to be −3.33 kg, and −0.29% on HbA1c (5,784 patients), with both findings weakened in sensitivity analyses. From all 10 lifestyle intervention groups, the pooled within-group effect on weight (3,063 patients) was −5.33 kg, which was also weakened in sensitivity analyses.

"Evidence-based approaches for improving the effectiveness of lifestyle-based interventions in type 2 diabetes are needed, along with future studies reporting on maintenance and cost-effectiveness," concluded the researchers.
