Healio (11/3, Herpen) reports a study found that “shorter total time in bed during school days and more frequent night awakenings were associated with an elevated suicide risk in U.K. adolescents.” Study participants aged 14 to 17 years “were tasked with reporting their sleep behaviors at age 14 based on six categories developed” by the Millennium Cohort Study: “bedtimes and wake times on both school and non-school days, 4-week sleep initiation intervals and 4-week frequency of nighttime awakenings.” Study results indicated that “shorter total time spent in bed on school days and more frequent night awakenings were significant predictors for suicide attempt at age 17.” The researchers “further reported that, with the frequency of awakenings acting as a predictor, rational decision-making moderated the association between night awakenings and suicide attempts.” The study was published in Sleep Advances.
