studyquestion: Dooverweight womenwith polycystic ovary syndrome(PCOS) have a higher risk of perinatal complications than normal weight women with PCOS? summaryanswer: Overweight women with PCOS with an ongoing singleton pregnancy have an increased risk of preterm birth aswell as an increased risk of giving birth to a baby with a higher birthweight than normal weight women with PCOS. what is known already: There is evidence that overweight (BMI. 25 kg/ m2) has a negative influence on the prevalence of gestational diabetes mellitus and fetal macrosomia in women with PCOS. study design, size, duration: We set up a retrospective comparative cohort study of 93 overweight ( BMI = 25 kg/ m2) and 107 normalweight (BMI, 25 kg/ m2) women withPCOSwhowere scheduled for fertility treatment between January 2000 and December 2009 and achieved a pregnancy as a result of a treatment cycle, or spontaneously before or between treatment cycles. participants/ materials, setting, methods: All data (patient characteristics, medical information, pregnancy, delivery and neonatal outcome) were retrieved frompatient medical files. All pregnancy, delivery and neonatal outcome parameterswere adjusted for age and pre- pregnancy smoking behaviour. The neonatal outcome parameters were additionally adjusted for gestational age. main results and the roleof chance: ThemedianBMIin the overweight and normal weightwomenwas, respectively, 30.8 kg/m2 [interquartile quartile range (IQR) 5.8] and 20.9 kg/ m2 (IQR 2.3) (P, 0.001). Baseline characteristics did not differ between groups, except for free testosterone and fasting insulin levels, which were higher, and sex hormone- binding globulin, which was lower, in overweight versus normal weight women ( all P, 0.001). The time- to- pregnancy was significantly higher in the overweight group ( P = 0.01). Multivariate analyses of the ongoing singleton pregnancies showed significantly more preterm births in overweight ( 10/ 61) versus normal weight (2/ 71) women [adjusted odds ratio 0.1, 95% confidence interval ( CI) 0- 0.6, P = 0.01]. The mean birthweight of newborns was significantly higher in overweight ( 3386 + 663 g) than in normal weight (3251+ 528 g) women ( adjusted mean difference 259.4, 95% CI 83.4- 435.4, P = 0.004). limitations, reason for caution: Our results only represent the pregnancy, delivery and neonatal outcome of ongoing singleton pregnancies. The rather small sample size and observational nature of the study are further limitations. wider implicationsof thefindings: Ourresults suggest the importance of pre- pregnancy weight loss in overweightwomenwith PCOS in order to reduce the risk of adverse perinatal outcomes. study funding/competing interest(s): Veerle De Fre` ne is holder of a Special PhD Fellowship by the Flemish Foundation for Scientific Research (FWO- Vlaanderen).
