Relationship between androgenetic alopecia and cardiovascular risk factors according to BASP classification in Koreans.

There have been many studies on the relationship between androgenetic alopecia (AGA) and cardiovascular risk factors, but the study results were inconsistent and research on AGA in Asians remains insufficient. This study investigated the relationship between Korean AGA and various cardiovascular risk factors, considering life habits, type of hair loss and sex. We investigated subjects who visited a hospital for public or industrial health medical examinations between October 2012 and December 2014. A questionnaire as well as anthropometric measurements and a blood test were performed. Among the 1884 total subjects, 52.6% had AGA. AGA patients displayed a significantly higher prevalence rate of cardiovascular diseases, smoking rate, fasting glucose and triglyceride, and a significantly lower high-density lipoprotein cholesterol level than did the non-AGA group. The results of the subgroup analysis showed higher prevalence rates of hypertension, stroke, metabolic syndrome and smoking in male AGA patients. The more severe the AGA, the higher the incidences of hypertension, diabetes and smoking were observed. According to the analysis results by BASP classification, the F-type AGA patients displayed a higher body mass index, waist circumference and diastolic blood pressure, and had a significantly higher prevalence rate of hypertension. As a result of the large population-based study, modifications in lifestyle and early screening for cardiovascular disease, as well as hypertension and diabetes, are suggested.
