androgenetic alopecia AGA body mass index BMI metabolic syndrome MetS dermatology

TLDR 15.33% of young Caucasian men have severe hair loss, with higher rates in Jewish men and links to age, BMI, and possibly metabolic syndrome.

The study examined the prevalence of severe androgenetic alopecia (AGA) in 24,702 young Caucasian men aged 30-40 years using photographs from the internet, particularly dating websites. It found a 15.33% prevalence of severe AGA, with higher rates in Jewish men and variations across geographical regions. The study identified age and higher body mass index (BMI) as significant risk factors for severe AGA and suggested a potential link between AGA and metabolic syndrome (MetS). The research highlighted the innovative use of internet-sourced images for epidemiological studies in dermatology, despite challenges like data accuracy and authenticity verification.
