Trends in Prevalence of Hypertriglyceridemia and Related Factors in Korean Adults: A Serial Cross-Sectional Study.

Abstract

Objective:

We aimed to investigate the longitudinal trends in prevalence of hypertriglyceridemia in Korean adults and hypertriglyceridemia-associated lifestyle habits, socioeconomic factors and comorbidities.

Methods:

Data from the 2007-2020 Korea National Health and Nutrition Examination Survey (KNHANES) were used in this study. Two cutoff values (≥150 mg/dL and ≥200 mg/dL) for fasting serum triglyceride levels were used to estimate the age- and sex-specific prevalence of hypertriglyceridemia. Use of lipid-lowering medications, lifestyle factors such as smoking, alcohol consumption, and regular exercise, socioeconomic variables such as educational attainment and household income, and comorbidities such as obesity, abdominal obesity, hypertension, and diabetes mellitus were also investigated.

Results:

The prevalence of hypertriglyceridemia among Koreans based on KNHANES 2007-2020 was 29.6% at ≥150 mg/dL and 16.1% at ≥200 mg/dL. While the rate of using lipid-lowering medications increased steadily from 2007 to 2020, changes in annual prevalence of hypertriglyceridemia were subtle. The prevalence of hypertriglyceridemia in men peaked in middle age (47.7% and 30.0% for ≥150 mg/dL and ≥200 mg/dL, respectively, in their 40s), but its prevalence in women increased throughout their lifetime (32.6% and 14.7% for ≥150 mg/dL and ≥200 mg/dL, respectively, in their 70s). Smoking and high-risk drinking exacerbated peak prevalence in both sexes. Young adults with any comorbidities had prominently increased prevalence of hypertriglyceridemia. The lowest levels of education and income were both associated with the higher prevalence of hypertriglyceridemia in both sexes.

Conclusion:

It is important to understand the age- and sex-specific epidemiology of hypertriglyceridemia to establish its appropriate management plans.
