The prevalence of metabolic syndrome and the associated factors in a multiethnic upper-middle-income country in Asia: findings from a nationwide community-based study in 2023
摘要
Metabolic syndrome (MetS) is a constellation of cardio-metabolic risk factors that predispose individuals to cardiovascular disease and type 2 diabetes. However, the current prevalence of MetS in Malaysia is unknown. Thus, we aimed to determine the prevalence of MetS and its associated factors among the adult population in Malaysia.
MethodsThis was a nationwide community-based cross-sectional study in Malaysia with two-stage stratified random sampling in 2023. MetS was defined based on the Harmonised Joint Interim Statement that required ≥ 3 metabolic risk abnormalities: abdominal obesity, elevated blood glucose, blood pressure, triglycerides, and low HDL-cholesterol. Complex sample analyses, including multiple binary logistic regression, were used to achieve the study objectives.
ResultsThe overall response rate was 71.4%, with 1,035 participants. The prevalence of MetS was 35.9% (95% CI: 31.4–40.6), translating to 8.5 million people in Malaysia. The prevalence of abdominal obesity, elevated blood glucose, elevated blood pressure, elevated triglycerides, and low HDL-cholesterol were 52.8%, 21.5%, 43.4%, 33.4%, and 44.6%, respectively. Increasing age groups, Indian ethnicity (aOR: 2.24, 95% CI: 1.19–4.22), elevated aspartate aminotransferase (aOR: 3.09, 95% CI: 1.50–6.35), and elevated gamma glutamyl-transferase (aOR: 3.30, 95% CI: 1.84–5.92) were independent factors associated with MetS.
ConclusionsMetS is highly prevalent in Malaysia and represents a pressing public health issue. Concerted multisectoral strategies are needed to manage this epidemic, and precise public health interventions can be targeted at the identified high-risk subpopulations for more effective and efficient outcomes.
