Abstract

Background:: Androgenetic alopecia (AGA) is a patterned hair loss occurring due to systemic androgen and genetic factors. It is the most common cause of hair loss in both genders. In recent years, many studies investigating the relation between systemic diseases and androgenetic alopecia presented controversial results.

Objectives:: In this study we aimed to investigate the frequency of androgenetic alopecia, the presence of accompanying systemic diseases, the relation between body mass index and androgenetic alopecia severity and the association of hyperandrogenemia signs with androgenetic alopecia in patients who referred to our outpatient clinic.

Methods:: Patients who referred to our clinic between October 2013 and May 2014 were included in the study. Diagnosis of androgenetic alopecia was made upon clinical findings. Presence of seborrhea and acne in both genders, and hirsutism in women, were examined. Age, gender, smoking habit and alcohol consumption, age of onset of androgenetic alopecia, family history, accompanying systemic diseases and abnormalities of menstrual cycle were recorded.

Results:: 954 patients (535 women, 419 men) were included in the study. Androgenetic alopecia prevalence found was 67.1% in men and 23.9% in women. Androgenetic alopecia prevalence and severity were correlated with age in both genders (p=0,0001). Frequency of accompanying systemic diseases were not significantly different between patients with and without androgenetic alopecia (p=0,087), except for hypertension, which was significantly more frequent in men with androgenetic alopecia aged between 50 and 59 years. Study limitations: Despite the exclusion of other causes of alopecia, differentiation of Ludwig grade 1 AGA from telogen effluvium based on clinical features alone is difficult.

Conclusions:: In our study the rate of androgenetic alopecia was found to be higher than the other studies made in Asian and Caucasian populations.
