摘      要：Objective: Determine whether waist- to- height ratio (WHtR) or sex- and ag e- specific percentiles of body mass index (BMI)- better identifies cardiovasc ular risk. Study design: The third National Health and Nutrition Examination Sur vey (NHANES III) provided measurements on 7657 participants statistically weight ed to represent 50.05 million youth 4 to 17 years of age. We estimated the subpo pulations corresponding to BMI strata that were normal ( BMI stratum. Compared with the 603 par ticipants (representing 3.70 million youth) who were discordant in the opposite direction, weighted analyses showed they had higher mean levels of heart rate, l ow- density lipoprotein (LDL) cholesterol, fasting triglycerides, and total cho lesterol (P < .015, adjusted for sex, age, and race- ethnicity). Their mean sys tolic blood pressure was lower, but this difference was eliminated after adjustm ent for their shorter stature. Conclusion: WHtR, a simpler anthropometric index than sex- and age- specific BMI percentiles, better identi- fies youth with a dverse cardiovascular risk factors.
