Sleep-Deprived Teens Risk Obesity
Teenagers who don’t get the recommended eight to nine hours of sleep each night could risk excessive weight gain as they become adults, a study found. Among 10,076 students in grades seven to 12 at the start of the study, 14 percent were already obese as teens, while another 7 percent became obese by age 21. Teen boys who slept for less than six hours a night were nearly twice as likely to be obese as their peers who regularly got more than eight hours of shut-eye, while there were no differences among girls. Teenage short sleepers of both sexes were about 20 percent more likely to be obese by age 21. The link remained even when researchers accounted for participants’ daily exercise and TV habits.
