In this investigation, conducted among 976 adult coloureds living in the Cape Peninsula, emphasis was placed on the relationship between type A (coronary-prone) behaviour and a number of other coronary risk factors (hypertension, hypercholesterolaemia, overweight and cigarette smoking), as well as certain demographic variables (age, occupational group and level of education). There was a fairly even distribution between high and low type A behaviour scores for both sexes in the groups aged 15 - 54 years, whereas there were proportionally fewer high than low scores in people between 55 and 64 years old. Housewives generally had lower scores than working women and other women who were not economically active. Both male and female respondents with high type A scores recorded on average higher systolic blood pressure readings. Type A men also smoked more than others. It appears that type A behaviour is mainly independent of other coronary risk factors.
在这项针对居住在开普半岛的976名成年有色人种开展的调查中，重点关注了A型（易患冠心病）行为与其他一些冠心病风险因素（高血压、高胆固醇血症、超重和吸烟）之间的关系，以及某些人口统计学变量（年龄、职业群体和教育水平）。在15至54岁的群体中，男女的A型行为高分和低分分布较为均匀，而在55至64岁的人群中，高分的比例比低分的少。家庭主妇的得分通常低于职业女性和其他没有经济活动的女性。A型行为得分高的男性和女性受访者平均收缩压读数更高。A型行为的男性吸烟也比其他人多。看来A型行为主要独立于其他冠心病风险因素。
