The positive effects of a peer-led intervention system for individuals with a risk of metabolic syndrome

Metabolic syndrome (MetS) is a major health risk in Thailand. Although it is reported that females have a higher rate of MetS than males, very few peer-led intervention studies have been conducted on specific groups, such as seamstresses, at risk of MetS. This study aimed to evaluate the effect of a peer-led intervention program on reducing MetS risk factors in individuals working in Thai Uniform Sewing Military Factories. A quasiexperimental program was introduced using a pre- and posttest design that was applied to female sewing factory workers selected for this research. All participants had at least one of the key MetS symptoms. The experimental group (N=50 participants) received 12 weekly peer-led individual support discussion sessions that included both dietary and physical activity (PA) advice and the control group (N=50 participants) followed their usual daily routines. The Student's -test and the Pearson's chi-squared test were used to compare the differences of baseline data and analysis of variance was used for analysis of the data after intervention. The results showed that after 3 months of participation, when compared to the control group, the experimental group had significantly improved systolic blood pressure (BP) ( =0.04), diastolic BP (
