The research followed 3,342 adolescents from 1996 through 2010, with participants reporting their normal bedtimes, fast food consumption, and time spent exercising and watching television at three points, the Times said. The researchers calculated each person's body mass index (BMI) at each of the three interviews, reported the New York Times.
Each hour of a delayed beditme was related to a 2-point increase in BMI, the report said. Fast food consumption was also related to increased BMI, but demographics, amount of sleep, exercise or time watching tv did not, reported the New York Times.
