Abstract

Importance: High lipid concentrations are a modifiable risk factor for cardiovascular disease. Little is known about how population-level lipid concentrations, as well as trends in lipid control, have changed over the past decade among US adults.Objective: To determine whether lipid concentrations and rates of lipid control changed among US adults and whether these trends differed by sex and race and ethnicity, from 2007 to 2018.Design, Setting, and Participants: Serial cross-sectional analysis of 33?040 US adults aged 20 years or older, weighted to be nationally representative, from the National Health and Nutrition Examination Surveys (2007-2008 to 2017-2018).Main Outcomes and Measures: Lipid concentrations among US adults and rates of lipid control among adults receiving statin therapy. Lipid control was defined as a total cholesterol concentration of 200 mg/dL or less.Results: The mean age of the study population was 47.4 years, and 51.4% were women; of the 33?040 participants, 12.0% were non-Hispanic Black; 10.3%, Mexican American; 6.4%, other Hispanic American; 62.7%, non-Hispanic White; and 8.5%, other race and ethnicities (including non-Hispanic Asian. Among all US adults, age-adjusted total cholesterol improved significantly in the overall population from 197 mg/dL in 2007-2008 to 189 mg/dL in 2017-2018 (difference, -8.6 mg/dL [95% CI, -12.2 to -4.9 mg/dL]; P for trend <.001), with similar patterns for men and women. Black, Mexican American, other Hispanic, and White adults experienced significant improvements in total cholesterol, but no significant change was observed for Asian adults. Among adults receiving statin therapy, age-adjusted lipid control rates did not significantly change from 78.5% in 2007-2008 to 79.5% in 2017-2018 (difference, 1.1% [95% CI, -3.7% to 5.8%]; P for trend=.27), and these patterns were similar for men and women. Across all racial and ethnic groups, only Mexican Americans experienced a significant improvement in age-adjusted lipid control (P for trend=.008). In 2015-2018, age-adjusted rates of lipid control were significantly lower for women than for men (OR, 0.54 [95% CI, 0.40 to 0.72]). In addition, when compared with White adults, rates of lipid control while taking statins were significantly lower among Black adults (OR, 0.66 [95% CI, 0.47 to 0.94]) and other Hispanic adults (OR, 0.59 [95% CI, 0.37 to 0.95]); no significant differences were observed for other racial and ethnic groups.Conclusions and Relevance: In this serial cross-sectional study, lipid concentrations improved in the US adult population from 2007-2008 through 2017-2018. These patterns were observed across all racial and ethnic subgroups, with the exception of non-Hispanic Asian adults.
