This study investigated prevalence and risk factors of metabolic syndrome (MetS) in a suburban community in Pathum Thani province, Thailand. Anthropometric data, blood pressure, blood glucose and lipid levels were recorded from 222 participants, 35-65 years old. Identification of MetS was based on guidelines of the National Cholesterol Education Program III. The study found the prevalence of MetS was 36.49% with no significant differences between male and female participants. An advancing body mass index (BMI) emerged as one of the most significant risk factors. Participants with BMI > 23 kg*m -2 had an increased risk of MetS (OR 3.17). Furthermore, participants in the age group 55-65 years had an increased risk of MetS (OR 2.28). Lack of exercise and high waist to height ratio were also important risk factors (OR 2.38 and 3.37, respectively). Therefore, increased physical activity or exercise and weight control are advised to reduce the prevalence of MetS.
