Cardiovascular risk factor variables were measured in a cohort of 440
infants at birth 6 months, and 1 year of age. Blood pressures at 6 months
of age were 93/47 mm Hg (systolic/diastolic pressure, fourth phase) and
97/51 mm Hg at 1 year of age. Serum total cholesterol, beta-lipoprotein,
and alpha-lipoprotein levels rose dramatically from birth to 1 year of age.
Serum triglycerides also showed an increase from birth to 6 months of age,
but a decrease from 6 months to 1 years of age. At 6 months of age, the
infants were consuming 949 kcal and at 1 year, 1,356 kcal. A statistically
significant correlation between serum cholesterol level and protein, fat,
cholesterol, and carbohydrate intake was noted at 1 year of age. These
observations provide a background for tracing the evolution of risk factor
variables as part of the early natural history of arteriosclerosis.
