Abstract
Relationships between diet and cardiovascular disease risk factors were studied in a cohort of infants in Bogalusa, Louisiana. The 24-hour dietary recalls and cardiovascular measurements were obtained on each child at age 6 months, yearly through age 4, and again at age 7 (cardiovascular measurements only). At ages 4 and 7, children with persistently high intakes of dietary cholesterol (three or more measurements in the upper tertile) had levels of serum total cholesterol approximately 14 mg/dl higher than children whose intakes of cholesterol were not persistently high. Children in the upper tertile for dietary cholesterol had levels of low density lipoprotein cholesterol (15 mg/dl at age 4 and 18 mg/dl at age 7) higher than children in the lower tertile for dietary cholesterol. Children with high intakes of animal fat were 2 to 6 kg heavier (p less than 0.05) than those with lower intakes. Changes in dietary cholesterol correlated significantly with changes in serum total cholesterol (r = 0.42) and low density lipoprotein cholesterol (r = 0.50) from 6 months to 4 years of age. Changes in subscapular skinfold measurements correlated significantly with changes in intake of total protein (r = 0.31), total fat (r = 0.25), starch (r = 0.31), and energy (r = 0.39) from ages 6 months to 4 years. Results indicate that tracking of dietary components and their relationships with cardiovascular disease risk factors can be detected at an early age. These findings may well be the groundwork for later studies of obesity and the early onset of hyperlipoproteinemia.
