Abstract:
- OBJECTIVE: Recent studies have suggested that androgenetic alopecia (AGA) may be associated with other disorders, especially metabolic syndrome (MetS). This study aimed to determine whether a connection exists between MetS and AGA based on the thickness of the subcutaneous adipose tissue in the scalp. PATIENTS AND METHODS: This cross-sectional study included 34 participants with AGA who had MetS and 33 participants with AGA who did not have MetS. The Hamilton -Norwood scale was employed for classifying AGA and MetS was identified using the US National Cholesterol Education Programme Adult Treatment Panel III (NCEP-ATP III criteria). The body mass index (BMI), blood pressure, and lipid profiles of the participants were assessed. Hepatosteatosis and the thickness of the subcutaneous adipose tissue in the scalp were examined using ultrasonography. RESULTS: Compared with the control group, the MetS+AGA group had higher BMI (p = 0.011), systolic blood pressure (p < 0.001), diastolic blood pressure (p < 0.001) and waist circumference (p = 0.003). Furthermore, the MetS+AGA group had a higher prevalence of dyslipidemia, hypertension (HT) and diabetes mellitus (DM) and higher rates of grade 6 alopecia than the control group (p = 0.019). Compared with the control group, those with MetS had thicker subcutaneous adipose tissue in the frontal scalp (p = 0.018). CONCLUSIONS: The subcutaneous adipose tissue in the frontal scalp was thicker in individuals with AGA who had high Hamilton scores. The concomitance of AGA and MetS may be associated with a high increase in subcutaneous adipose tissue and less favorable metabolic parameters.
