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

This study involving 613 women, including 308 with female androgenetic alopecia (AGA) and 305 controls, found that higher consumption of carbonated sodas and sweetened tea drinks is associated with an increased risk of developing AGA. Occasional intake of carbonated soda increased the risk by 1.535 times, while sweetened tea drinks increased the risk by 1.978 to 2.044 times. Poor sleep quality was also linked to a higher risk and severity of AGA, suggesting that sleep behavior may mediate the relationship between soft drink consumption and AGA. The study emphasizes the potential impact of dietary and lifestyle factors on hair health in women and suggests that reducing sweetened tea intake and improving sleep habits could help prevent alopecia. However, the study notes limitations such as a small sample size and reliance on self-reported data, indicating the need for further research.
