The association of Type A/B behavior pattern and changes in blood pressure, total serum cholesterol, serum triglyceride, body mass, and smoking was estimated in a cohort of 375 young Black and White men and women from a rural county in Central Kentucky between 1978-79 and 1985-88. Type A participants experienced significant increases in systolic (2.90 +/- 1.29 mmHg) and diastolic (3.80 +/- 1.17 mmHg) blood pressure and in cigarette smoking (3.26 +/- 0.89 cigarettes per day) over the eight-year follow-up period, but Type B participants experienced no change. Type A and B individuals showed similar changes in total serum cholesterol, serum triglyceride, or body mass. Differences between behavioral types in blood pressure were present for women but not men, and for Blacks but not for Whites. These findings suggest a possible significance of the Type A pattern for the development of cardiovascular risk of young adults.
1978 - 1979年至1985 - 1988年间，对肯塔基州中部一个乡村县的375名年轻黑人和白人男性及女性组成的队列进行了研究，以评估A/B型行为模式与血压、血清总胆固醇、血清甘油三酯、体重及吸烟变化之间的关联。在八年的随访期内，A型参与者的收缩压（2.90±1.29 mmHg）和舒张压（3.80±1.17 mmHg）以及吸烟量（每天3.26±0.89支）均有显著增加，而B型参与者则无变化。A型和B型个体在血清总胆固醇、血清甘油三酯或体重方面表现出相似的变化。行为类型在血压上的差异存在于女性而非男性，以及黑人而非白人中。这些发现表明，A型模式可能对年轻成年人心血管风险的发展具有重要意义。
