A study by
researchers at Columbia University's Mailman School of
Public Health found that female students, racial / ethnic minorities, and students of lower socioeconomic status are particularly affected, with teens in these categories less likely to report regularly getting seven or more hours of sleep each night compared with their
male counterparts, non-Hispanic white teenagers, and students of higher socioeconomic status, respectively.
According to the
researchers» article in the American Journal of
Public Health, they found that the odds of a woman driver who is wearing a seatbelt suffering a serious injury is 47 percent higher than that of a belted
male driver in a comparable automobile accident.
