Prevalence of metabolic syndrome in the United States National Health and Nutrition Examination Survey 2011–18

This study included 8183 eligible nonpregnant participants aged ≥20 years from the NHANES 2011-18. MetS was defined as the presence of at least three of the following components: central obesity, reduced high-density lipoprotein cholesterol, elevated triglycerides, elevated blood pressure, and elevated fasting blood glucose. The prevalence of MetS was estimated taking into account the complex sampling. The time trend was evaluated using logistic regression.

The total prevalence of MetS increased from 37.6% [95% confidence interval (CI): 34.0%-41.4%] in 2011-12 to 41.8% (95% CI: 38.1%-45.7%) in 2017-18 (P for trend = .028). Among the MetS components, the prevalence of elevated glucose increased from 48.9% (95% CI: 45.7%-52.5%) in 2011-12 to 64.7% (95% CI: 61.4%-67.9%) in 2017-18 (P for trend
