Prevalence of the Polycystic Ovary Syndrome in Female Residents of Chengdu, China

Abstract

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.

Are expanding disease definitions unnecessarily labelling women with polycystic ovary syndrome?

“…A substantial proportion of younger women, such as those with menstrual irregularity and raised free testosterone at one assessment (phenotype F, table 2⇓) might meet the strict NIH definition but can experience spontaneous resolution over time (fig 1)⇓. 3 Three studies in different populations found that prevalence of PCOS rapidly fell after 25 years of age, indicating that the symptoms and signs of PCOS might be transitory for many women. …”

Effects of exercise and dietary habits on the occurrence of polycystic ovary syndrome over 5 years of follow‐up

“…Polycystic ovary syndrome (PCOS) is a common but complex disease with oligoanovulation, hyperandrogenism, and polycystic ovary as the main clinical features. The prevalence of PCOS is 6%–18% in women of reproductive age and is 11.2% in southwest China . However, the etiology and risk factors of PCOS are unclear and require further exploration.…”

Predictors of Gestational Diabetes Mellitus in Chinese Women with Polycystic Ovary Syndrome: A Cross-Sectional Study

“…It is a common endocrinopathy in women, affecting approximately 5-10% of the reproductively mature women [1,2,3]. This complex reproductive metabolic disorder is associated with insulin resistance, hyperandrogenism, obesity and weight-related disorders [4,5].…”
