Prevalence and types of androgenetic alopecia in north Anatolian population: A community-based study.

OBJECTIVE
To determine the prevalence and pattern of androgenetic alopecia in Turkey and to compare the results with different regions.


METHODS
The community-based study was carried out from September 2012 to June 2013 across all the 12 districts of Tokat province of Turkey. Individuals 20-years-old or older were included, and more than two first-degree relatives were excluded. Dermatological examination of all the subjects was performed by dermatologists. The degree of androgenetic alopecia was classified according to the Hamilton-Norwood and Ludwig classifications.


RESULTS
Of the 2322 volunteers, 1288(55.46%) were women and 1034(44.53%) were men. Overall mean age was 47.3±15.3 years (range: 20-87 years). Androgenetic alopecia was detected in 740(31.8%) subjects; 247(19.17%) women and 493(47.6%) men.


CONCLUSIONS
The prevalence of androgenetic alopecia in Turkish society was higher than Asian and African communities; and similar to the rate in European societies hair-loss.
