Psychosocial risk factors for cardiovascular disease in women: the role of social support.

Lack of social support is becoming increasingly important as a psychosocial risk factor in the study of coronary heart disease (CHD). There may also be an association between vital exhaustion and lack of social support. Because most research has focused on men, we decided to explore the associations between structural and functional social support and first myocardial infarction (MI) in women. Subjects were 79 women hospitalized with a First MI (mean age 59.3; SD = 9.3) and 90 women hospitalized with an acute surgical event (mean age 57.4: SD = 9 1). MI cases reported more vital exhaustion than did controls (p < ,040), and exhausted women reported less structural (p < .001) and functional support (p < .000). After controlling for age, hypertension, diabetes, menopausal status, smoking, nonanginal pain, and vital exhaustion, multiple logistic regression analysis showed that poor structural support was associated with an increased risk for MI. These results suggest that social support is associated with vital exhaustion, which is a well-known risk factor for CHD. Furthermore, it is suggested that women with only a few confidants are more at risk for MI even after adjustment for well-known risk factors for CHD.
