Group-based programs help reduce insulin resistance for metabolic syndrome

The Tabaruzaka study published in the Diabetes, Obesity, and Metabolism journal Sept 2010 aimed to evaluate the efficacy of two group-based lifestyle interventions in ameliorating the risk factors of metabolic syndrome (MS) and insulin resistance.


The study followed ninety-eight subjects who had at least one component of MS for 34 months. At month 34, BMI and HDL-cholesterol improved significantly. Insulin sensitivity and hepatic insulin resistance were also improved.

The conclusion was that group-based programs could be an efficient way to prevent MS. Its effects were sustainable, at least in part, for 2 years. These effects may be mediated by an improvement in insulin sensitivity.
