Parental history and cardiovascular disease risk factor variables in children

As part of a total community study of cardiovascular disease (CVD) risk factor variables in children (ages 5–17 years), parental histories of heart attacks, hypertension, diabetes, and stroke were obtained for each of 4,074 participating children. Subsequently, each child was examined for serum total cholesterol, triglycerides, lipoproteins (LP) and glucose, measurement of height, weight, triceps skinfold thickness, and blood pressure (BP), and had a physical examination. A family history of high BP was reported by 26.5% of all children, diabetes by 7.1%, heart attacks by 6.8%, and stroke by 2.1%. The children of parents with heart attacks or diabetes were heavier and had different lipid and LP profiles than children without this background. Children of reported hypertensive parents had higher systolic and diastolic BP, were heavier and had thicker skinfolds. The heaviest children were more likely to have a parental history of diabetes, hypertension, and heart attack. Children in the highest decile for systolic or diastolic BP were more likely to come from a family reporting hypertension. Children with the highest cholesterol, triglycerides, β + pre-β-LP and lowest α-LP values tended to have parents with heart attacks or diabetes. These data indicate that familial tendencies in multiple CVD risk factors are observable early in life. Children of parents with CVD or manifested risk factors clearly differ in their own risk factor profiles from children of parents without these conditions.
