Prevalence of a positive family history of type 2 diabetes in women with polycystic ovarian disease

Abstract

The known association between insulin resistance and polycystic ovarian disease (PCOD) has been studied by determination of the prevalence of a positive family history of diabetes in a consecutive series of oligomenorrheic women with polycystic ovaries and eumenorrheic women with normal ovaries who served as controls.A significantly greater proportion of the families of the patients with PCOD had at least one member affected by type 2 diabetes (39.1% of the PCOD group and 7.6% of the controls; p < 0.001). Both obese (54.8%) and non-obese women (24.2%) with PCOD had an increased prevalence of type 2 diabetes within their families. Paternal and maternal family members affected were in similar proportions, there being no evidence of preferential transmission through the female line in this study.The increased prevalence of type 2 diabetes in the families of women with polycystic ovaries is further evidence for the association between PCOD and insulin resistance, and provides a possible explanation for the familial nature of the ovarian disorder.
