Abstract

BACKGROUND
Androgenetic alopecia (AGA) is the most common type of hair loss, and androgens and genetic predisposition are believed to be the major factors that influence the development of AGA. Although there have been previous reports about the relationship between family history, smoking and insulin resistance with AGA, no previous study has investigated lifestyle habits such as eating habits in AGA patients.
OBJECTIVE
The aim of this study was to investigate family history, lifestyle including smoking and eating habits in AGA patients and to compare the results with data from Korea Health Statistics 2009: Korea National Health and Nutrition Examination Survey (KNHANESIV-3).
METHODS
We retrospectively evaluated a total of 347 male patients with AGA who visited the Department of dermatology, Inha University School of medicine, from September 2010 to August 2012.
RESULTS
AGA with paternal family history was the most common (49.9%), and both of maternal and paternal family history was the least (10.1%). Body mass index and smoking did not show significant differences but eating habits showed a statistically significant difference according to the duration of AGA. Patients with longer disease duration (> or =60 months) showed higher intake of meat but low intake of fish than those with shorter disease duration (<12 months). Also, AGA patients showed low intake of beef, bean and squid in comparison to the average Korean population.
CONCLUSION
This was the first study which investigated lifestyle habits such as eating habits in AGA patients and compared the results with data from Korea Health Statistics. However, a further large scale Cohort study is needed to define the casual relationship between eating habits and the development of AGA. Also, a further study including the difference of serum and hair androgen levels in relation to different lifestyle habits should be done.
