Gender-specific risk factors for androgenetic alopecia in the Korean general population: Associations with medical comorbidities and general health behaviors

Abstract

Background

The relationships between androgenetic alopecia (AGA) and various factors related to metabolic syndrome have been demonstrated in previous studies. However, it remains unclear because of inconsistent results. We investigated the associations between AGA and various risk factors related to metabolic syndrome according to gender.

Methods

We conducted a population-based cross-sectional survey of 2028 Koreans (1050 men, 978 women). The basic and specific (BASP) classification was used for diagnosis of AGA. We collected information on risk factors though questionnaires and medical records.

Results

AGA was significantly associated with age, family history of AGA, hypertension, diabetes mellitus, and waist circumference in both genders. Female subjects with AGA were more likely to have cerebrovascular disease, dyslipidemia, and obesity; however, these associations were not observed in the male subjects. When multiple regression analysis was applied, there was a significant relationship between hypertension and AGA in male subjects. However, there was no statistically significant association in female subjects.

Conclusion

The different results according to gender might arise from different mechanisms of AGA. There was a significant relationship between hypertension and AGA in male subjects. Evaluation of blood pressure in male patients with AGA might facilitate interventions for hypertension.
