ABSTRACT
Objective: To determine the prevalence of polycystic ovary syndrome (PCOS) according to the three major diagnostic criteria previously described in an unselected group of women from Spain and to identify the most common phenotypes of the disease.
Material and method: An observational, transversal prevalence study was carried out between July 1 2014 and October 31 2014. All participants received a questionnaire and underwent a physical and transvaginal ultrasound examination. Blood samples were also collected for analysis of metabolic markers and hormones. PCOS was diagnosed according to three major criteria: NIH, Rotterdam and AE-PCOS criteria. Following diagnosis women with PCOS were assigned to one of four phenotypes.
Results: A total of 242 women were involved in the study. The prevalence for each major criteria was as follows: National Institute of Health (NIH) criteria had a prevalence of 14.88%, Rotterdam criteria had a prevalence of 29.34% and Androgen Excess and PCOS Society criteria presented a prevalence of 17.36%. The prevalence for each phenotype was: A, 40.85%; B, 25.35%; C, 8.45%; and D, 25.35%. PCOS women had more prevalence of hirsutism (36.61%), infertility (25.35%), obesity (21.12%) and metabolic syndrome (11.26%) than controls (7.01%, 6.43%, 5.84% and 2.33% respectively).
Conclusion: There is a rise in the prevalence of PCOS in Caucasian population with the classic phenotype (oligo-anovulation, hyperandrogenism, polycystic ovaries) being the most common presentation of the syndrome.
