Peer Review of The Mediation Role of Sleep on the Relationship Between Drink Behavior and Female Androgenetic Alopecia

The study examined the link between sweetened tea drink consumption and female androgenetic alopecia (AGA) in 613 women, including 308 AGA patients and 305 controls. It found that both occasional and frequent sweetened tea intake increased the risk of AGA. Higher sugar intake from soft drinks and hyperglycemia were also associated with a greater risk. Importantly, bedtime after 12 am significantly increased alopecia risk, with sleep behavior mediating the relationship between sweetened tea consumption and AGA. The study suggests that managing sweetened tea intake and sleep habits could help prevent AGA, though it notes limitations such as a small sample size for severe cases and reliance on self-reported data.
