Background: Polycystic ovary syndrome (PCOS) is one of the most common endocrine disorders in women. The data on this syndrome in a Chinese community are limited.
Methods: A community-based cross-sectional survey was undertaken. Cluster-randomized sampling was used. Female residents of Chengdu aged between 12 and 44 were included according to the constituent ratio of the female population of Sichuan province. We used three diagnostic criteria to determine the prevalence: the National Institutes of Health diagnostic criteria of PCOS (NIH-1990), the revised Rotterdam diagnostic criteria of PCOS (Rott-2003), and the recommended diagnostic criteria of PCOS by the Androgen Excess Society (AES-2006).
Results: 1,645 participants were included. The prevalence of PCOS in women aged between 12 and 44 was 7.1, 11.2 and 7.4%, respectively, according to the three different criteria. After the onset of puberty, the prevalence of PCOS increased rapidly from 12 to 14 years of age, peaked between 15 and 24 and decreased gradually thereafter and reached its lowest point before menopause.
Conclusions: The prevalence of PCOS in this study was in the PCOS prevalence range from existing studies. According to the trend of prevalence, PCOS might be a temporary condition.
