Abstract: Sleep duration improves short-term following bariatric surgery; however, little is known about its association with bodyweight medium- to long-term post-surgery. The purpose of this study was to describe sleep duration and its relationship with BMI and body composition. Forty-nine individuals, with a BMI of 36.6±9.8 kg/m2, regained 26.4±17.8% of their lost weight 9.5±3.3 years post-surgery (range 3–16 years). Sleep logs and ActivPAL3 accelerometers were used to assess sleep duration. Participants averaged 7.9±1.6 h/day and 8.5±1.7 h/day of sleep for weekdays and weekends, respectively (P<0.01). A positive association between delta weekend-weekday sleep timing midpoint with BMI (ß=0.03, 95% CI=0.01, 0.06; P=0.01) was noted in the multivariable-adjusted model. On average, this sample achieved recommended sleep durations medium- to long-term post-surgery. Having an earlier sleep timing midpoint during the weekend may be associated with lower BMI.
