Why the study?
Do age, sex, and family influence Type A and hostility indices related to coronary heart disease risk?
Do age, sex, and family influence Type A and hostility indices related to coronary heart disease risk?
Males exhibit heightened hostility indices compared to females, which may partially account for their increased risk of coronary heart disease.
Sex differences in hostility may relate to male CHD risk excess; leaves open prospective validation of Type A indices in risk prediction.
We describe the influence of age, sex, and family on Type A and hostility indices that have been related to rates of coronary heart disease (CHD). The sample consisted of 120 girls and 95 boys (ages 6 to 18 years) and 141 women and 120 men (ages 31 to 62 years) from 142 families residing in an upper middle class community. Results showed little familial aggregation of Type A and hostility. Adults had higher Structured Interview (SI) Potential for Hostility ratings than did children, whereas children had higher Minnesota Multiphasic Personality Inventory (MMPI)-derived Hostility scores and SI Anger-In ratings than did adults. Male adults and male children had higher SI Potential for Hostility ratings and MMPI-derived Hostility scores than did their female counterparts. The heightened hostility of males may account, in part, for their heightened risk of CHD relative to females'.
