This study aimed to estimate the prevalence and risk factors of androgenetic alopecia (AGA) in men aged 40-69 years in Australia. The study found that the prevalence of vertex and full AGA increased with age, while the proportion of men with only frontal AGA was similar across all age groups. Alcohol consumption was associated with an increased risk of both frontal and vertex AGA, while the lifetime number of female sexual partners was negatively associated with vertex AGA. The study concluded that the prevalence of vertex AGA increases with age, while the prevalence of only frontal AGA appears to be constant. The study suggests that future research on the determinants of AGA should preferably be couched within prospective cohort studies.
