title: Hostility, social support, and coronary heart disease in the National Heart, Lung, and Blood Institute Family Heart Study.
abstract: This cross-sectional study investigated the association of hostility and social support to coronary heart disease (CHD) in 2 groups of men and women: those with a familial predisposition for CHD (high-risk sample) and a randomly selected group. The hypothesis was that hostility and low social support would be associated with CHD, and would have a greater effect in the high-risk group. The random sample contained 2,447 individuals (47.1% male) from 576 families, and the high-risk sample consisted of 2,300 people (45.5% male) from 542 families. Odds ratios (OR) and their 95% confidence intervals were calculated using generalized estimating equations (GEE) for logistic regression. Family was specified as the clustering variable, and robust SEEs were obtained to account for dependence of the data within families. After controlling for age, education, body mass index, exercise, smoking history, drinking history, and drinking >5 drinks a day, hostility was associated with a history of coronary bypass surgery or coronary angioplasty in high-risk men (OR 1.21) and a history of myocardial infarction in high-risk women (OR 1.39). High-risk women with high social support had reduced odds of a previous myocardial infarction (OR 0.76), whereas women with high network adequacy in the random sample had reduced risk of myocardial infarction (OR 0.41) and angina (OR 0.49). A ratio of high hostility to low social support was associated with past myocardial infarction in high-risk women (OR 2.47) and a history of angina (OR 2.02) in the random sample men. These results suggest that high hostility and low social support are associated with some manifestations of CHD after controlling for adverse health behaviors.
