[BDSP. Notice produite par INIST zgR0xT6X. Diffusion soumise à autorisation]. Objectives. This study was done to assess changes in obesity and risk factors for cardiovascular disease (CVD) in Black and White children from 1975 through 1990. Methods. A cross-sectional study of body composition and CVD risk factors conducted in a school district as part of the Lipid Resarch Clinics (LRC) Program Prevalence Study (1973-1975) was compared with a later study (1989-1990) conducted in the same school district, which remained demographically stable. The studies included 1456 third-and fifth-grade students and 300 LRC subjects within the same age ranges. Results. Students in the 1989*1990 study had a significantly higher mean body mass index (BMI°, total blood cholesterol concentration, and systolic and diastolic blood pressures and marginally higher resting heart rates than those in the earlier study. The prevalence of obesity increased from 12.5% to 25.3%, and of hypercholesterolemia from 8.0% to 14.8%. Black females had the largest increase in BMI and resting heart rate and the highest prevalence of elevated total cholesterol in the 1989-1990 study. Conclusions. The results of this study suggest a secular trend toward increased obesity in children and portend the potential development of a public health problem that could reverse the recent decline in porbidity from CVD.
