Abstract :

Hirsutism (i.e. facial and body terminal hair growth in a male-like pattern in women) is the principal clinical sign of hyperandrogenism, although its definition remains unclear. We conducted a cross-sectional, population-based study by using a multistage systematic cluster random sampling among 16 communities from two rural and two city regions in southern China, to determine the normative cut-off score that defines hirsutism, and the effect of age, menstrual irregularities (MI), and polycystic ovaries (PCO) on the same. Totally, a representative sample of 2,988 women aged 20-45 years underwent physical and ultrasound evaluations; and their terminal hair growth were assessed using the modified Ferriman-Gallwey (mFG) scoring system. An mFG score of >5 was observed in 10% and a score of >2 in 25% of the subjects. Cluster analysis identified an mFG score of 5 as the cut-off value that defines hirsutism in the total population; scores of 6, 5, and 4 for women aged 20-25, 26- 30, and >30 years, respectively. Defined by these cut-off values, the prevalence of hirsutism was 10.5%; and decreased with increasing age: 14.4%, 10.7%, 7.9%, 3.6%, and 1.5%, respectively, in women aged 20-25, 26-30, 31-35, 36-40, and 41-45 years. Furthermore, the incidence of acne, MI, PCO, and acanthosis nigricans were significantly increased among the hirsute women. This suggested that an mFG score of ≧5 indicates hair growth above the norm among women in the general Southern Chinese population, a cut-off value that decreases with increasing age.
