Prevalence of cervical insufficiency in polycystic ovarian syndrome.

Background: Pregnant women with polycystic ovarian syndrome (PCOS) experience a greater rate of adverse obstetrical outcomes compared with non-PCOS women. We examined the prevalence and incidence of cervical insufficiency (CI) in a community cohort of pregnant women with and without PCOS.

Methods: A retrospective cohort study was conducted within a large integrated health care delivery system among non-diabetic PCOS women with second or third trimester delivery during 2002-2005 (singleton or twin gestation).

Epidemiology and adverse cardiovascular risk profile of diagnosed polycystic ovary syndrome.

Context: Polycystic ovary syndrome (PCOS) is associated with menstrual and reproductive abnormalities, insulin resistance, and obesity.

Objective: The objective of this study was to determine the prevalence of diagnosed PCOS and its association with cardiovascular risk factors.

Setting: The study is set in an integrated health care delivery system in northern California.
