Methodology: Polycystic ovary syndrome (PCOS) has a variety of signs and symptoms compromising different phenotypic presentations. Insulin resistance is a known association of PCOS. Despite the documented effect of ethnicity on insulin resistance, there is little known about the effect of ethnicity on the clinical presentations of PCOS. We compared the clinical presentations of white and South Asian (SA) women with PCOS.

Methodology: Retrospective analysis of a clinical database of all PCOS women attending one UK endocrine unit (1988–2009). Androgen criteria are defined as one of; hirsutism, acne, androgenic alopecia or increased free androgen index. Anovulation criteria are defined as oligo-amenorrhoea or infertility. Ethnicity was self-registered by patients. Only white and SA data have been presented.

Results: Of 2207 patients, 684 (30%) were SA. White women had a higher metabolic risk profile (hypertension, smoking and BMI) and less diabetes, while SA had more androgenic and less anovulatory criteria, were younger at presentation and had more deprived background (Table 1).

Conclusion: There appears to be a significant affect of ethnicity on the clinical and phenotypic presentation of PCOS. Understanding these differences may help tailor appropriate management in defined groups of patients with this condition.
