[Association between androgenetic alopecia and metabolic syndrome: a meta-analysis].

In 2014, a meta-analysis was conducted to investigate the association between androgenetic alopecia (AGA) and metabolic syndrome (MS). The analysis included four case-control studies and two cross-sectional studies, involving 950 AGA subjects and 3056 control subjects. The results showed a significant correlation between AGA and MS (OR=2.70, 95%CI: 1.67-4.37, P<0.01). This correlation was significant in both male (OR=2.30, 95%CI: 1.33-3.98, P<0.01) and female subjects (OR=4.61, 95%CI: 1.26-16.94, P<0.05), and in both European (OR=5.29, 95%CI: 2.86-9.80, P<0.01) and Asian subjects (OR=1.92, 95%CI: 1.18-3.10, P<0.01). The conclusion was that AGA may be a risk factor for MS, suggesting that AGA patients could be a target population for screening of metabolic syndrome.
