Background: Polycystic ovary syndrome (PCOS) is considered a risk factor for the development of type 2 diabetes mellitus (T2DM). However, which is the most appropriate way to evaluate dysglycemia in women with PCOS and who are at increased risk are as yet unclear. Aim of the study: To determine the prevalence of T2DM, impaired glucose tolerance (IGT), and impaired fasting glucose (IFG) in PCOS women and potential factors to identify those at risk. Subjects and methods: The oral glucose tolerance test (OGTT), biochemical/hormonal profile, and ovarian ultrasound data from 1614 Caucasian women with PCOS and 362 controls were analyzed in this cross-sectional multicenter study. The data were categorized according to age and BMI. Results: Dysglycemia (T2DM, IGT, and IFG according to World Health Organization criteria) was more frequent in the PCOS group compared to controls: 2.2% vs 0.8%, P = 0.04; 9.5% vs 7.4%, P = 0.038; 14.2% vs 9.1%, P = 0.002, respectively. OGTT was essential for T2DM diagnosis, since in 88% of them basal glucose values were inconclusive for diagnosis. The presence of either T2DM or IFG was irrespective of age (P = 0.54) and BMI (P = 0.32), although the latter was associated with IGT (P = 0.021). There was no impact of age and BMI status on the prevalence of T2DM or IFG. Regression analysis revealed a role for age, BMI, fat deposition, androgens, and insulin resistance for dysglycemia. However, none of the factors prevailed as a useful marker employed in clinical practice. Conclusions: One-third of our cohort of PCOS women with either T2DM or IGT displayed normal fasting glucose values but without confirming any specific predictor for dysglycemcondition. Hence, the evaluation of glycemic status using OGTT in all women with PCOS is strongly supported. © 2022 The authors Published by Bioscientifica Ltd.

Purpose: The exact risk of type 2 diabetes mellitus (T2DM) in women with polycystic ovary syndrome (PCOS) is unknown. It is also unclear if obesity independently increases T2DM risk in this population. The aim of this study was to systematically review and synthesize the best available evidence regarding the association between PCOS and T2DM, stratified according to obesity status. Methods: A comprehensive search was conducted in PubMed, CENTRAL and Scopus databases up to October 31, 2020. Data are expressed as relative risk (RR) with 95% confidence interval (CI). The I2 index was employed for heterogeneity. Results: The eligibility criteria were fulfilled by 23 studies (319,780 participants; 60,336 PCOS and 8847 type 2 diabetes cases). Women with PCOS demonstrated a higher risk of T2DM than those without PCOS (RR 3.45, 95% CI, 2.95–4.05, p < 0.001; I2 81.6%). This risk remained significant both in studies matched or unmatched for participants’ age. With regard to body mass index (BMI), the RR for developing T2DM in obese and non-obese PCOS women compared with their non-PCOS counterparts was 3.24 (95% CI 2.25–4.65; p < 0.001; I2 30.9%) and 1.62 (95% CI 0.14–18.50; p = 0.70; I2 89.9%), respectively. The RR for developing T2DM was 3.85 (95% CI 1.99–7.43; p < 0.001; I2 46.2%) in obese compared with non-obese women with PCOS. This was also the case for overweight compared with lean women with PCOS. Conclusions: Women with PCOS present an increased risk of T2DM compared with non-PCOS women only if they are obese/overweight. © 2021, The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature.
