NHANES data show prevalence of high total cholesterol among US adults aged 20+How many American adults have high cholesterol? A new look at national data

This observational analysis used data from the National Health and Nutrition Examination Survey (NHANES) collected between 2015 and 2018. The study population consisted of adults aged 20 years or older in the United States, though the exact sample size was not reported. The analysis focused on determining the prevalence of high total cholesterol in this population.

The primary outcome was the prevalence of high total cholesterol, but the specific prevalence rate, effect sizes, absolute numbers, p-values, and confidence intervals were all not reported in the available evidence. No direction of association or comparative data were provided. The study did not examine any specific interventions or exposures related to cholesterol management.

No safety or tolerability data were reported since this was a prevalence study without intervention components. Key limitations include the absence of reported prevalence rates and statistical measures, which prevents quantitative assessment of the cholesterol burden. The practice relevance is limited to providing a general awareness that high total cholesterol was examined in this national survey population, but clinicians cannot draw specific prevalence estimates or management implications from the unreported results.
