Prevalence of metabolic syndrome in the United States National Health and Nutrition Examination Survey (nhanes) 2011–2018

Abstract

Abstract Background Metabolic syndrome (MetS) is a cluster of risk factors presaging the development of cardiovascular disease and diabetes. It is a risk factor for severe coronavirus disease 2019 (COVID-19). Purpose To estimate the prevalence of MetS in the US National Health and Nutrition Examination Survey (NHANES) 2011–2018. Methods This cohort study included 22370 eligible participants aged ≥20 years from the NHANES 2011–2018. MetS was defined as the presence of at least three of these components: central obesity, reduced high-density lipoprotein, 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. Annual percentage changes (APC) were measured trend in MetS prevalence. Results The prevalence of MetS was 36.2% (95% CI, 32.3–40.3), 34.8% (95% CI, 32.3–37.4), 39.9% (95% CI, 36.6–43.2) and 38.3% (95% CI, 35.3–41.3) in 2011–2, 2013–4, 2015–6, 2017–8, respectively (P for trend = 0.08). Among the MetS components, the prevalence of elevated glucose increased from 48.7% (95% CI, 45.9–51.5) in 2011–2 to 64.3% (95% CI, 61.0–67.4) in 2017–8 [P for trend <0.001; APC=11.7, (95% CI, 3.5–21.0)]. The prevalence of MetS in non-Hispanic Asian increased from 21.8% (95% CI, 16.7–28.0) in 2011–2 to 31.2% (95% CI, 27.4–35.3) in 2017–8 [P for trend <0.001; APC=14.6, (95% CI, 2.5–34.8)]. Conclusions The prevalence of MetS remained stable during 2011 to 2018. Lifestyle modification is needed, especially among non-Hispanic Asians to prevent the metabolic syndrome and the associated risks of diabetes and cardiovascular disease.
