Article Abstract
Purpose: Metabolic syndrome (MetS) is a major risk factor for cardiovascular diseases and type-2 diabetes. The study aimed to establish the efficacy of a community-based lifestyle intervention on MetS in Kenyan adults using randomized control trial involving a 15-months follow up.
Methods: A randomized controlled trial involving 352 (18-64 years old) adults with MetS spanning 15-months duration. Participants were recruited from a Nairobi based Mission-led outpatient clinic, randomly assigned equally into intervention and control groups. The intervention group was exposed to a community-based health education on lifestyle modification, while control group was subjected to hospital-led routine care involving treatment and general lifestyle advice. The study was structured into baseline, intervention and evaluation phases with inbuilt data collection in each phase. Physiologic, anthropometric, and clinical parameters as well lifestyle characteristics were measured at baseline, midline and end-line. The parameters were compared across the groups and between the time points during analyses using chi-square test, binary logistic, independent t-test and paired t-test.
Results: Proportion of participants with MetS declined significantly ( < 0.001) with marked ( < 0.05) improvement in markers of MetS (elevated BP, raised sugars, cholesterols, central obesity) in intervention compared to control group. The rates of consumption of fruits, vegetables, legumes, nuts and uptake of physical activity significantly ( < 0.05) improved in the intervention group. However, the intake of processed/fast foods, salt, sugar, and alcohol significantly ( < 0.05) declined in the intervention compared to controls by the end-line.
Conclusion: One in three adults under the community-based lifestyle intervention had improvement in physiologic, anthropometrics and clinical markers relevant to definition of MetS. Additionally, an improved adherence to the recommended dietary intake and increased uptake of physical activity in adults with MetS was observed. These findings underscore the feasibility, effectiveness and proof of concept for community-based lifestyle approach as a viable strategic intervention for addressing premorbid risk factors for cardiovascular CVDs and diabetes before evolving into full blown conditions in low-income settings.
