| アブストラクト | CONTEXT: Polycystic ovary syndrome (PCOS) is the most common cause of anovulatory infertility and may be associated with adverse pregnancy and neonatal outcomes. However, it is difficult to establish how much of this risk is due to PCOS and how much to obesity. OBJECTIVE: This study aimed to determine the effect of PCOS upon fertility, pregnancy, and neonatal outcomes. DESIGN AND SETTING: Data were extracted from the Clinical Practice Research Datalink (CPRD), a longitudinal anonymized primary care research database in the United Kingdom. Patients with a diagnosis of PCOS were matched to controls (1:2) by age (+/-1 y), body mass index (+/- 3 U), and CPRD practice. Standardized fertility ratios before and after diagnosis (index date) were calculated. Rates of miscarriage, pre-eclampsia, gestational diabetes, premature delivery, delivery method, and neonatal outcomes were compared. RESULTS: Nine thousand sixty-eight women with PCOS matched study criteria. Prior to index date the standardized fertility ratio for patients with PCOS was 0.80 (95% confidence interval, 0.77-0.83); following index date it was 1.16 (1.12-1.20). The adjusted odds ratios (95% CI) for miscarriage (1.70; 1.56-1.84), pre-eclampsia (1.32; 1.16-1.49), gestational diabetes (1.41; 1.2-1.66), and premature delivery (1.25; 1.1-1.43) were all increased compared with controls. Of PCOS births, 27.7% were by Caesarean section compared with 23.7% of controls (1.13; 1.05-1.21). Infants born to mothers with PCOS had an increased risk of neonatal jaundice (1.20; 1.03-1.39) and respiratory complications (1.20; 1.06-1.37). CONCLUSIONS: PCOS is associated with subfertility but fertility rates are restored to those of the background population following diagnosis. Pregnancy complications and adverse neonatal outcomes are more prevalent for women with PCOS independently of obesity. |
