Jonasson M, Hendryx M, Manson JAE, et al. - Researchers examined how personality traits are associated with the risk of coronary heart disease (CHD) or stroke in women with diabetes. They followed 15,029 women, from the Women's Health Initiative (aged 50 to 79 years at enrollment), with self-reported treated diabetes at baseline or follow-up for a mean of 10 years. Using validated scales, they measured personality traits including hostility, optimism, ambivalence over emotional expressiveness, and negative emotional expressiveness. They observed a total of 1,118 incident CHD and 710 incident stroke cases among these women. The analysis revealed that, among postmenopausal women with diabetes—especially among incident diabetes—there may be association of hostility with the incidence of CHD. Results thereby afford a base for targeted prevention programs for women with a raised level of hostility and diabetes.
