[BDSP. Notice produite par INIST 7LR0xN6z. Diffusion soumise à autorisation]. Context Knowledge about ethnic differences in cardiovascular disease (CVD) risk factors among children and young adults from national samples is limited. Objective To evaluate ethnic differences in CVD risk factors, the age at which differences were first apparent, and whether differences remained after accounting for socioeconomic status (SES). Design Third National Health and Nutrition Examination Survey, 1988-1994. Setting Eighty-nine mobile examination centers. Participants A total of 2769 black, 2854 Mexican American, and 2063 white (non-Hispanic) children and young adults aged 6 to 24 years. Main Outcome-Measures Ethnicity and household level of education (SES) in relation to body mass index (BMI), percentage of energy from dietary fat, cigarette smoking, systolic blood pressure, glycosylated hemoglobin (HbA1c), and non-high-density lipoprotein cholesterol (non-HDL-C [the difference between total cholesterol and HDL-C]). Results The BMI levels were significantly higher for black and Mexican American girls than for white girls, with ethnic differences evident by the age of 6 to 9 years (a difference of approximately 0.5 BMI units) and widening thereafter (a difference of>2 BMI units among 18-to 24-year-olds). Percentages of energy from dietary fat paralleled these findings and were also significantly higher for black than for white boys. (...)
