  The early lesions of atherosclerosis begin in childhood and are related to antecedent cardiovascular disease (CVD) risk factors. Environmental and genetic factors (eg, diet, obesity, exercise, and certain inherited dyslipidemias) influence progression of such lesions. Identification of youth at risk for atherosclerosis includes an integrated assessment of these predisposing factors. Treatment starts with a diet low in total and saturated fat and cholesterol, use of water-soluble fiber, plant stanols and plant sterols, weight control, and exercise. Drug therapy, for example, with inhibitors of hydroxymethylglutaryl-CoA reductase, bile acid sequestrants, and cholesterol absorption inhibitors, can be considered in those with a positive family history of premature CVD and low-density lipoprotein cholesterol >160 mg/dL after dietary and hygienic measures. Candidates for drug therapy often include those with familial hypercholesterolemia, familial combined hyperlipidemia, the metabolic syndrome, polycystic ovarian syndrome, type 1 diabetes, and the nephrotic syndrome. Such dietary and drug therapy appears safe and efficacious. Early identification and treatment of youth with CVD risk factors and dyslipidemia are likely to retard the atherosclerotic process. Optimal detection and treatment of high-risk children either from the general population or from families with premature CVD will require a comprehensive universal screening and evaluation program.

Background

Lipoprotein subfractions in infants may predict the risk of cardiovascular disease factors in children.

Objective

To examine the relationships between lipid and nonlipid factors and lipoprotein subfractions in infants at birth and follow-up (FU) and in their parents.

Methods

Prospective study in a community-based hospital of 103 families ascertained through a pregnant mother at 36 weeks gestation or older. Of 103 infants studied at birth, 85 were sampled at FU at 2-3 months of age, along with 76 fathers. Lipids, lipoproteins, and their subclasses were determined by nuclear magnetic resonance spectroscopy. Correlations of lipid-related parameters were calculated using Spearman rank correlations.

Results

Female gender in infants and use of formula only were the only nonlipid variables associated with lipoprotein subfractions. LDL parameters were significantly correlated between infants at birth and FU. The largest high-density lipoprotein subfraction, H5C, was the only lipid variable significantly associated between mothers and infants at birth. Paternal low-density lipoprotein size was significantly correlated with that of infants at FU but not at birth. In each of the four groups, markedly inverse interrelationships were found between H5C and small LDL particles. At birth and at FU, apoC-I was strongly related with H5C but not TG. Conversely, apoC-I in the parents was strongly related with TG but not H5C.

Conclusion

Significant relationships were found between lipoprotein subfractions within infants at birth and FU and their parents. ApoC-I and H5C levels very early in life may affect the development of dyslipidemia and obesity in childhood.
