Background: In spite of the possible association of type A behavior with coronary heart disease, the pathogenic mechanism linking them are not well understood. Several prospective studies revealed type A behavior as an independent risk factor for coronary heart disease, suggesting that it is relatively unrelated to other coronary risk factors. However, these results are controversial. Thus,
this study examines the relationships between coronary risk factors, particularly, hypercholesterolemia and type A behavior.
Methods: The patient group consisted of 110 patients visiting six university hospitals in the vicinity of Seoul and Gyeonggi Province from May 2006 to September 2007, and the control group was 112 patients without hypercholesterolemia from the same hospitals from the same period. Informations regarding medical history and sociodemographic factors from all 222 subjects were obtained through a questionnaire. To survey behavior patterns, the Danakawa Type A Behavior Questionnaire which is based on the Jenkins Activity Survey was conducted among study participants.
Results: Sociodemographically, there were no significant differences between groups. However, the patient group showed a significantly higher rate in high blood pressure among the coronary risk factors. Type A behavior pattern was seen in 68 patients (61.8%) in the patient group compared to 50 (44.6%) in the control group, and its difference was significant (χ2=6.574, P=0.010). After
adjusting coronary risk factors and other significant variables, type A behavior pattern remained significantly related to an elevation in plasma total cholesterol (χ2=4.51, P=0.034).
Conclusions: Our study indicates that type A behavior is related to an elevation in plasma cholesterol but unrelated to other coronary risk
factors in adults. More prospective studies on this topic are required.
