Background and aims: Cholesterol control and management in patients with hypercholesterolemia are significant for the primary and secondary prevention of atherosclerotic cardiovascular disease. This study analyzed the trend of serum total cholesterol (TC) control (<240 mg/dL and <200 mg/dL) in American adults with hypercholesterolemia and thereby make some effective recommendations for the public health measures.
Methods and results: Basing on the National Health and Nutrition Examination Survey (NHANES) data from 1988 to 2018 (12 cycles), we calculated the weighted and representative rate of patients with hypercholesterolemia who had controlled TC, and then described the trend. Among the adults with hypercholesterolemia, the age-adjusted rate of those whose TC was less than 240 mg/dL increased from 7.67% (95%CI: 5.94%-9.40%) in 1988-1991 to 58.52% (95%CI: 55.89%-61.15%) in 2013-2014 and then remained stable; and the age-adjusted rate of those whose TC was less than 200 mg/dL increased from 2.49% (95%CI: 1.48%-3.50%) in 1988-1991 to 44.58% (95%CI: 40.00%-49.16%) in 2017-2018.
Conclusion: We concluded that the rate of controlling TC below 200 mg/dL among all patients had shown an increasing trend from 1988 to 2018 in America, while the rate of controlling TC below 240 mg/dL remained stable in recent years after an increasing.
