“…A meta‐analysis in 2017 reviewed the prevalence of PCOS across different ethnic groups and concluded that women from Middle Eastern countries and black women are more likely to develop PCOS as compared with Asian women . In Iran, China, and the United States, a prevalence of 3%, 2.2%, and 4.7%, respectively, has been reported; in Brazil, Beijing, Sri Lanka, Palestine, Greece, the United Kingdom, and Spain, the prevalence is reported to range from 5% to 10%, whereas Denmark, Turkey, and Australia have reported higher rates (15%–20%) . The discrepancies in reported prevalence might be due to small sample sizes, narrow age groups (15–25 years), presence of other disease, inclusion of diagnosed women, and differences in socioeconomic and regional characteristics, lifestyle, and diagnostic criteria.…”
