Ethnic-specific polycystic ovary syndrome: Epidemiology, significance and implications

摘要

Being the most common endocrinopathy of young women, polycystic ovary syndrome has much variation in its clinical expression based on ancestry. Ethnic differences of the phenotype are closely linked to its complex pathophysiology. This paper reviews data of the past three decades ensuring a precise diagnosis and taking into account underlying factors, effects of migration including heterogeneity, and diversity within each identified ethnic group. Differing expressions of hyperandrogenism, obesity, insulin resistance and metabolic manifestations of polycystic ovary syndrome occur among women from distinct geographic locations and ancestry. These ethnic phenotypes correlate with their inherent metabolic risks, skin sensitivity to androgens and social outlook that particularly affects their quality of life and health-seeking behavior. It is recommended that such ethnic variations are recognized in routine clinical practice and longitudinal data be maintained to study the true impact of such differences on disease outcomes.
