title: Risk factors for metabolic syndrome in a cohort study in a north China urban middle-aged population.
abstract: As China undergoes urbanization, lifestyles and disease profiles are changing. In this study, metabolic syndrome (MetS) was discovered in 53.5% and 42.7% of men and women, respectively. In 3 age cohorts (44, 48, and 52 years), prevalence of MetS among women was 33.3%, 41.4%, and 50.8%, respectively (χ(2) = 10.27, P = .006), whereas among men it was 51.5%, 56.3%, and 52.3%, respectively (χ(2) = 0.46, P = .796). The component contributing to the presence of MetS was increased waist circumference, especially among women. MetS among men results from higher rates of elevated triglycerides, blood pressure, and blood glucose when compared with women. Risk factors for MetS included less than 60 minutes of exercise a week (odds ratio [OR] = 1.7, 95% confidence interval [CI] = 1.3-2.4) and rarely consuming milk (OR = 1.7, 95% CI = 1.2-2.3). Abstaining from or occasionally consuming alcohol (OR = 0.7, 95% CI = 0.4-1.1) and having parents with no chronic disease (OR = 0.4, 95% CI = 0.2-0.6) suggest increased protection against MetS.
