SI conversions: To convert serum total, HDL, and LDL cholesterol to mmol/L, multiply by 0.0259; and serum triglyc- eride to mmol/L, multiply by 0.0113. *Total and HDL cholesterol levels are based on all examined adults; LDL cholesterol and serum triglyceride levels are based on adults examined in the morning who fasted 8.5 to 23 hours before venipuncture. LDL cholesterol was calculated by the Friedewald equation (serum total cholesterol-HDL cholesterol-serum triglyceride/5), valid for in- dividuals with a serum triglyceride level of 400 mg/dL or less ( 4.52 mmol/L).22 Age-adjusted for the entire population by the direct method to the US census population projected estimates for the year 2000 using the age groups 20 to 39 years, 40 to 59 years, and 60 years or older.42 Includes data for racial/ethnic groups not shown separately. §Significantly different from women of the same age or race/ethnicity group at P .05.
