Prevalence and Standard Errors of High LDL-C Levels by Number of Risk Factors Among Men Aged 20 to 35 Years and Women Aged 20 to 45 Years (N = 2,587), NHANES, 1999–2006

Risk FactorsaHigh LDL-Cb % (SE)High LDL-Cb,c Risk Ratio (95%
CHD = coronary heart disease; CI = confidence interval; LDL-C = low-density lipoprotein cholesterol; NHANES = National Health and Nutrition Examination Survey.
aRisk factors: high blood pressure, smoking, family history, and obesity.
bLDL-C ≥100, ≥130, and ≥160 mg/dL for high, intermediate, and low NCEP ATP III risk categories, respectively.
cN = 2,402 due to missing data. Each model was adjusted for race/ethnicity, education, poverty status, medical insurance status, and health care access during last 12 months, and age (continuous).
dSelf-reported coronary heart disease, angina, myocardial infarction, stroke, or diabetes (self-reported or fasting blood glucose ≥126 mg/dL).
eLinear trend across risk categories assessed by calculating orthogonal polynomial coefficients according to the method of Fisher and Yates; P value for linear trends <.001.
