Aim: To compare the prevalence of metabolic syndrome (MetS) between women with polycystic ovary syndrome (PCOS) and controls across different age (20, 21-30 and 31-39 years old) and body mass index (BMI) (normal weight, overweight and obese) groups. Methods: We studied 1223 women with PCOS and 277 BMI-matched controls. The prevalence of MetS in women with PCOS and controls was estimated according to four different MetS definitions. Results: In subjects 20 and 21-30 years old, the prevalence of MetS did not differ between women with PCOS and controls regardless of the MetS definition, even though women with PCOS were more obese than controls in the 20 years old group. In subjects 31-39 years old, the prevalence of MetS was higher in women with PCOS than in controls but the former were more obese than controls. The prevalence of MetS did not differ significantly between women with PCOS and controls in any of the BMI groups (normal weight, overweight or obese) regardless of the MetS definition. Conclusion: The prevalence of Mets appears to be primarily determined by obesity and age whereas PCOS per se appears to be a less important contributing factor. © 2013 Informa UK Ltd.

Study Question: Do women with the polycystic ovary syndrome (PCOS) differ from those with the metabolic syndrome (MetS) in markers of insulin resistance (IR) and circulating androgens? Summary Answer: Women with MetS have more pronounced IR than those with PCOS whereas only the latter have elevated circulating androgens. What is Known Already: PCOS and MetS share many similarities, including abdominal obesity and IR, and PCOS is regarded as the ovarian manifestation of MetS. However, there are limited data on the differences between markers of IR and circulating androgens between women with these two syndromes. Study Design , Size, Duration A prospective study in 1223 Caucasian women with PCOS and 277 women without PCOS, matched for BMI, was performed between May 2004 and December 2011. The presence/absence of MetS in PCOS+ and PCOS-women was recorded and comparisons among the resulting four groups were performed. Participants/Materials, Setting, Methods This study was performed in a university department of obstetrics and gynecology. The following markers of IR were determined: serum glucose and insulin levels, glucose/insulin ratio, area under the oral glucose tolerance test, homeostasis model assessment of IR index and quantitative insulin sensitivity check index. Main Results and the Role of Chance: PCOS+MetS+ women (n = 361) were more insulin-resistant than PCOS+MetS-women (n = 862) (P < 0.001 for the comparisons in all markers of IR). Similarly, PCOS-MetS+ women (n = 66) were more insulin-resistant than PCOS-MetS-women (n = 211) (P < 0.001 for the comparisons in all markers of IR). In contrast, PCOS+MetS+ showed only borderline significant differences in some markers of IR compared with PCOS-MetS+ women (P < 0.05). Similarly, PCOS+MetS-women showed only borderline significant differences in some markers of IR compared with PCOS-MetS-women (P = 0.037). Moreover, PCOS-MetS+ women were more insulin-resistant than PCOS + MetS-women (P < 0.001 for the comparisons in all markers of IR). Regarding circulating androgens, PCOS+MetS+ women had higher levels of circulating androgens than PCOS-MetS+ women (P < 0.001 for the comparisons in all circulating androgens). Similarly, PCOS+MetS-women had higher levels of circulating androgens than PCOS-MetS-women (P < 0.001 for the comparisons in all circulating androgens). In contrast, circulating androgens did not differ between PCOS+MetS+ women and PCOS+MetS-women. Similarly, circulating androgens did not differ between PCOS-MetS+ women and PCOS-MetS-women. Limitations, Reasons For Caution Only Caucasian women were included in the study. IR was not assessed with the euglycemic hyperinsulinemic clamp. Wider Implications of the Finding: s: Even though MetS and PCOS have many similarities, they are distinct disorders. PCOS does not appear to simply represent the ovarian manifestation of MetS. Further studies are required to assess the contribution of hyperandrogenism to the pathogenesis of IR in PCOS.

Objective: The polycystic ovary syndrome (PCOS) and the metabolic syndrome (MetS) are common disorders that share many characteristics, particularly abdominal obesity and insulin resistance. Our objective was to compare the prevalence of MetS between a large cohort of patients with PCOS and body mass index -matched controls. Design Cross-sectional study. Patients We studied 1223 patients with PCOS and 277 healthy women. Diagnosis of PCOS was based on the revised Rotterdam criteria. Women with PCOS were divided into those who fulfilled both the Rotterdam criteria and the diagnostic criteria of the 1990 National Institutes of Health definition of PCOS (group 1, n = 905) and into those with the additional phenotypes introduced by the Rotterdam criteria (group 2, n = 318). Diagnosis of MetS was based on four different definitions. Measurements Anthropometric, metabolic, hormonal and ultrasonographic features of PCOS. Results: The prevalence of metabolic syndrome (MetS) was higher in women with PCOS than in controls when the National Cholesterol Education Program Adult Treatment Panel III definition of MetS was applied (15.8% and 10.1%, respectively; P = 0.021) but not with the three more recent MetS definitions. The prevalence of MetS was higher in group 1 than in controls regardless of the applied MetS definition. In contrast, the prevalence of MetS was similar in group 2 and in controls regardless of the applied MetS definition. In logistic regression analysis, PCOS did not predict the presence of MetS. Conclusions: Polycystic ovary syndrome per se does not appear to increase the risk of MetS independent of abdominal obesity. © 2012 Blackwell Publishing Ltd.
