A prospective study of positive early life psychosocial factors and favorable cardiovascular risk in adulthood

Abstract

Background-The American Heart Association's national goals for cardiovascular health promotion emphasize that cardiovascular risk originates early in life, but little is known about childhood factors that may increase the likelihood of having a favorable cardiovascular risk (FCR) in adulthood. We examined the prospective association between positive childhood factors and the likelihood of midlife FCR. We also considered pathways through which childhood factors may influence FCR.Methods and Results-We studied 415 adults (mean age=42.2 years) of the Collaborative Perinatal Project, a national cohort initiated in 1959 to 1966. We examined 3 positive childhood factors assessed at age 7 years: attention regulation (ability to stay focused), cognitive ability, and positive home environment. Of these adults, 10.6% had FCR in midlife. Adjusting for demographics and childhood cardiovascular health, a 1-unit increase in childhood attention regulation, cognitive ability, and positive home environment was associated with 2.4 (95% confidence interval, 1.1-4.7), 1.8 (95% confidence interval, 1.1-2.9), and 1.3 (95% confidence interval, 1.1-1.6) higher respective odds of having midlife FCR. The association with childhood attention regulation was maintained when accounting for adulthood factors; education and diet in part explained the associations with childhood cognitive ability and home environment. The effect of each attribute was additive as those with high levels of each childhood factor had 4.3 higher odds (95% confidence interval, 1.01-18.2) of midlife FCR in comparison with those low in all factors.Conclusions-Positive childhood psychosocial factors may promote healthy adult cardiovascular functioning. Primordial prevention efforts aimed at preventing the development of cardiovascular risk should consider building on childhood psychosocial resources. (Circulation. 2013; 127: 905-912.)
