Description
Summary:CONTEXT Serum total and low-density lipoprotein (LDL) cholesterol contribute significantly to atherosclerosis and its clinical sequelae. Previous analyses of data from the National Health and Nutrition Examination Surveys (NHANES) showed that mean levels of total cholesterol of US adults had declined from 1960-1962 to 1988-1994, and mean levels of LDL cholesterol (available beginning in 1976) had declined between 1976-1980 and 1988-1994. OBJECTIVE To examine trends in serum lipid levels among US adults between 1960 and 2002, with a particular focus on changes since the 1988-1994 NHANES survey. DESIGN, SETTING, AND PARTICIPANTS Blood lipid measurements taken from 6098 to 15 719 adults who were examined in 5 distinct cross-sectional surveys of the US population during 1960-1962, 1971-1974, 1976-1980, 1988-1994, and 1999-2002. MAIN OUTCOME MEASURES Mean serum total cholesterol, LDL cholesterol, high-density lipoprotein (HDL) cholesterol, and geometric mean serum triglyceride levels, and the percentage of adults with a serum total cholesterol level of at least 240 mg/dL (≥6.22 mmol/L). RESULTS Between 1988-1994 and 1999-2002, total serum cholesterol level of adults aged 20 years or older decreased from 206 mg/dL (5.34 mmol/L) to 203 mg/dL (5.26 mmol/L) (P=.009) and LDL cholesterol levels decreased from 129 mg/dL (3.34 mmol/L) to 123 mg/dL (3.19 mmol/L) (P
