Overall, 45.2% of the young women had scores indicating poor sleep quality. Women who said they consumed energy drinks or high-calorie coffee beverages were more likely to report poor sleep quality, the authors report in the journal Sleep Health. “First, that prevalence of poor sleep quality was so high – almost half of the participants reported poor sleep quality,” she noted. “Second, that (consuming) sugary coffee drinks, even some compared with none, was associated with poor sleep quality.”The study wasn’t designed to prove that coffee-based drinks caused the women’s sleep problems. Young pointed out that sleep quality scores were only modestly worse among women who consumed sugary caffeine drinks compared to those who didn’t, and future studies are needed to determine if drinking sugary coffee drinks affects sleep quality.
