OBJECTIVE
Examine how changes in sleep duration, objectively measured by activity trackers, impact weight gain in incoming college freshman. Incoming college freshmen, age ≥ 18. We measured weight and daily sleep duration before college entry and through the 1st college quarter. Additionally, we examined changes in sleep variability, activity levels and smartphone screen time use as possible predictors of weight gain. 75 participants completed the study. Total sleep duration decreased from 437.9 ± SD 57.3 minutes at baseline to 416.5 ± SD 68.6 minutes by the end of the first quarter ( = 6.6 × 10). (BMI) did not change significantly in this cohort. Higher sleep variability at baseline and an increase in sleep variability were associated with increases in BMI. Smartphone screen use was note to be high (235.2 ± 110.3 minutes/day) at the end of the first quarter. College weight gain may be affected by factors other than sleep duration, including sleep variability.

目的
通过活动追踪器客观测量的睡眠时间变化，研究其对新入学大学生体重增加的影响。 研究对象为年龄≥18 岁的新入学大学生。我们在入学前和第一大学季度测量了体重和每日睡眠时间。此外，我们还研究了睡眠变异性、活动水平和智能手机屏幕使用时间的变化，这些变化可能是体重增加的预测因素。 75 名参与者完成了这项研究。总睡眠时间从基线时的 437.9±SD57.3 分钟减少到第一季度末的 416.5±SD68.6 分钟（ =6.6×10）。（BMI）在该队列中没有明显变化。基线时睡眠变异性较高和睡眠变异性增加与 BMI 增加有关。第一季度末智能手机屏幕使用时间（235.2±110.3 分钟/天）较高。 大学体重增加可能受睡眠持续时间以外的因素影响，包括睡眠变异性。
