摘要
目的 调查大学生卧室夜间光暴露与客观测量的睡眠参数的关联,为促进大学生睡眠健康提供参考。方法 2019年9—10月,采用方便抽样法在安徽医科大学、安徽中医药大学2所高校招募365名健康的大学生,建立大学生队列。使用便携式照度计(TES-1339R;Taishi Corp,台湾地区,中国)连续2 d在个体水平上测量卧室夜间光暴露,通过腕戴式加速计(ActiGraph GT3X-BT, Pensacola, FL)连续7 d客观评估大学生睡眠参数。使用多元线性回归模型检验卧室夜间光暴露与大学生睡眠参数的关联。结果 相较于夜间平均光照强度较低(<3 lx)组,夜间平均光照强度较高(≥3 lx)组大学生睡眠效率更低[(93.5±2.7)%,(92.2±2.9)%,t=3.93]、入睡后觉醒时间更长[(24.7±10.3)(29.2±11.2)min,t=-3.66]、运动指数更高(11.0±3.6,12.2±3.8,t=-2.80)、睡眠碎片化指数更高(20.5±6.5,23.0±7.0,t=-3.24)(P值均<0.01)。多元线性回归模型结果显示,在调整协变量后,相较于夜间平均光照强度较低组,夜间平均光照强度较高组的睡眠效率降低(β=-1.15,95%CI=-1.78~-0.52),入睡后觉醒时长、运动指数、睡眠碎片化指数均增加[β值(95%CI)分别为3.94(1.55~6.33),1.05(0.20~1.89),2.35(0.81~3.88)](P值均<0.05)。结论 夜间光暴露影响大学生睡眠,卧室光照管理有助于提升青少年睡眠质量。
Objective To investigate the cross-sectional association between bedroom nocturnal light exposure and objectively measured sleep parameters in college students,so as to provide evidence for promoting sleep health.Methods From September to October 2019,a convenience sampling method was used to recruit 365 healthy college students from two universities in Hefei,establishing a cohort.Bedroom nocturnal light exposure was measured at the individual level for two consecutive days using a portable illuminometer(TES-1339R;Taishi Corp,Taiwan region,China).Sleep parameters were objectively measured over seven consecutive days using wrist-worn accelerometers(ActiGraph GT3X-BT,Pensacola,FL).Multiple linear regression models were employed to examine the association between nocturnal light exposure and sleep parameters.Results Compared to the low nocturnal light exposure(<3 lx)group,the high-exposure(≥3 lx)group exhibited significantly lower sleep efficiency[(93.5±2.7)%,(92.2±2.9)%,t=3.93],longer wake after sleep onset(WASO)[(24.7±90.3)(29.2±11.2)min,t=-3.66],higher movement index(11.0±3.6,12.2±3.8,t=-2.80),and higher sleep fragmentation index(20.5±6.5,23.0±7.0,t=-3.24)(all P<0.01).After adjusting for covariates,multiple linear regression showed that,compared to the low nocturnal light exposure group,the high-exposure group had reduced sleep efficiency(β=-1.15,95%CI=-1.78 to-0.52),increased WASO[β(95%CI)=3.94(1.55-6.33)],higher movement index[β(95%CI)=1.05(0.20-1.89)],and elevated sleep fragmentation index[β(95%CI)=2.35(0.81-3.88)](all P<0.05).Conclusions Light exposure at night negatively impacts college students'sleep.Optimizing bedroom lighting management may improve sleep quality in adolescents.
