Nutrition and Lifestyle Behavior Peer Support Program for Adults with Metabolic Syndrome: Outcomes and Lessons Learned from a Feasibility Trial

Background: While peer support interventions have shown to benefit adults with certain chronic conditions, there is limited evidence on its feasibility and effectiveness among people with metabolic syndrome (MetS). This paper describes the outcomes of a pre-post feasibility trial of “PEeR SUpport program for ADults with mEtabolic syndrome” (PERSUADE), an evidence-based and community-specific nutrition and lifestyle behavior peer support program for Malaysian adults with MetS. Methods: We recruited 48 peers (median age: 46 (IQR = 11) years old) into four peer groups, who underwent 3 months of PERSUADE, followed by 3 months of follow-up period. Statistical analyses were conducted at post-intervention and post-follow-up to assess the changes in nutrition intake, anthropometry, and metabolic parameters. Results: Although there were significant overall increases in total carbohydrate intake and glycemic load (both p < 0.001), we noted significant reductions in the intakes of total energy and fat (both p < 0.001). Physical activity (total METS/week) also showed a significant improvement (p < 0.001). Overall, significant but marginal improvements in anthropometric and vital metabolic parameters were also observed. Conclusions: The feasibility trial supported the adoption of PERSUADE, though there is a need to assess the long-term impact of the peer support program in local community settings.
