High cholesterol can double a person's risk for heart disease, the leading cause of death in the US. A simple blood test can detect levels of LDL (bad) and HDL (good) cholesterol, and treatment and lifestyle changes can prevent high cholesterol or keep it under control.

Percentage of Adults with High Cholesterol Whose LDL Cholesterol Levels are Adequately Controlled
Proportion of people with high LDL-cholesterol whose levels meet control goals for their risk group. Numerator: Those whose LDL cholesterol (LDL-C) levels are under control. Controlled high LDL-C: LDL-C less than LDL-C goals and currently taking medication to lower cholesterol (based on positive responses to the following questions: Have you ever had your blood cholesterol checked?; Have you ever been told by a doctor or other health professional that your blood cholesterol level was high?; To lower your blood cholesterol have you ever been told by a doctor or other health professional to take prescribed medicine?; Are you now following this advice to take prescribed medicine?). Denominator: Individuals 20+ years with high LDL cholesterol or currently on lipid lowering medication. Crude prevalence estimates (i.e., not age-adjusted) of civilian, non-institutionalized population are provided. LDL-C goals are defined in the following Morbidity and Mortality Weekly Report (MMWR) on February 4, 2011: www.cdc.gov/mmwr/preview/mmwrhtml/mm6004a5.htm?s_cid=mm6004a5_w
Inclusion Criteria: All non-pregnant survey participants ages 18+ years with non-zero cholesterol measurements and non-missing response to cholesterol questionnaire.
Exclusion Criteria: Pregnant women.
Estimates for 18-39 year olds were not statistically reliable.
Data used for these analyses required fasting blood samples which were done on a one-half sample of the survey participants and resulted in smaller sample sizes, so multiple years of data were needed to produce statistically reliable estimates Two cycles (4 years) of data were pooled to create the estimates by population characteristics because of sample size limitations.
Due to small samples sizes that tend to have greater variability, confidence intervals are displayed, which are important for interpreting the variability around the prevalence point estimates.
For insurance estimates, the following definitions are used: Private insurance excludes plans that pay for only one type of service, such as dental or vision care. Persons covered by both Medicare and Medigap plans are classified as having public coverage. Public coverage includes Medicaid, Children’s Health Insurance Program (CHIP), state-sponsored or other government-sponsored health plan, Medicare (disability), Indian Health Service or military health care (TRICARE, VA, or CHAMP-VA).
This measure is calculated by the Centers for Disease Control and Prevention, National Center for Health Statistics from the National Health and Nutrition Examination Survey.
