Abstract
Background: Prevalence and types of androgenetic alopecia (AGA) are fraught with great variation and the association between smoking and AGA remains controversial.
Objective: To estimate the prevalence of AGA in Taiwanese men and to evaluate its association with smoking.
Methods: Two data from Community-based sample of men (n=743) aged 32 to 91 years and from occupation-based sample of the policemen (n=758) aged 20 to 64 years were available for analysis. All were interviewed in person and direct observations of AGA were made by the trained staffs using standardized classification for AGA. The association between smoking and AGA was assessed by using unconditional logistic regression.
Results: The prevalence of AGA in men in Taiwan increased with age, but was lower than that in Caucasians. After adjusting for age and family history of AGA, we found a significant positive association between smoking and AGA in the community-based program but not in occupation-based program. The relationships of family history of AGA or degrees of relationship to occurrence of AGA was demonstrated to be statistically significant.
Conclusions: This is the first population-based cross-sectional survey for the prevalence of AGA in Taiwanese men. Smoking is found to be positively associated with moderate or severer AGA.
