Teens Gain Weight If Goes Late To Bed: Study
Researchers have found a link between late going to bed and weight gain among teenagers.
Researchers from University of California studied the data of 3,342 teens between 1996 and 2009. Their usual bedtime, television watching time, exercises and fast food consumption were recorded during three interviews at three different times.
Based on the data received the researchers calculated their Body Mass Index (BMI) on each interview.
Details of the study are published in the October issue of Sleep journal. It writes each hour late bedtime during hectic week is linked to a 2.1 points increase in BMI.
Researcher Lauren Asarnow said, “The results are important because they highlight adolescent bedtimes, not just total sleep time, as a potential target for weight management concurrently and in the transition to adulthood.”
Asarnow was the lead author of the study and a doctoral candidate at the University of California, Berkeley. He said this is the first study to look at the longitudinal relationship between bedtimes and BMI.
According to The American Academy of Sleep Medicine, more than nine hours of nightly sleep is required for adolescents to get proper daytime alertness as well as to achieve optimal health during the transition from childhood to adulthood.
