目的为了确定是否学龄前儿童较早的就寝时间有一个较低的风险，青少年肥胖和是否这种风险降低是修改由maternalsensitivity.Study设计数据从977的1364名参与者的研究早期儿童保健和青年发展进行了分析。1991年在美国10个研究中心的健康单胎分娩符合入组条件。在1995-1996年，母亲报告他们的学龄前儿童（平均= 4.7年）的典型的工作日就寝时间，和母子互动进行了观察，以评估母亲的敏感性。在平均年龄为15岁时，测量身高和体重，青少年肥胖定义为性别特异性体重指数年龄>=美国参考值的第95百分位数。结果四分之一的学龄前儿童早睡（晚上8：00或更早），一半的儿童在晚上8：00后但在晚上9：00前睡觉，四分之一的人晚睡（晚上9点以后）。无论母亲的敏感性如何，儿童的就寝时间相似（P = .2）。在早睡组和晚睡组中，青少年肥胖的患病率分别为10%、16%和23%。早睡学龄前儿童与晚睡学龄前儿童青少年肥胖的多变量校正相对危险度（95%CI）为0.48（0.29，0.82）。这种风险没有修改母亲的敏感性（P = 0.99）。结论学龄前儿童早期工作日就寝时间是一半的儿童晚就寝时间是肥胖的青少年。就寝时间是一个可以改变的常规，可能有助于预防肥胖。
Objective To determine whether preschool-aged children with earlier bedtimes have a lower risk for adolescent obesity and whether this risk reduction is modified by maternal sensitivity.Study design Data from 977 of 1364 participants in the Study of Early Child Care and Youth Development were analyzed. Healthy singleton-births at 10 US sites in 1991 were eligible for enrollment. In 1995-1996, mothers reported their preschool-aged (mean = 4.7 years) child's typical weekday bedtime, and mother-child interaction was observed to assess maternal sensitivity. At a mean age of 15 years, height and weight were measured and adolescent obesity defined as a sex-specific body-mass-index-for-age >= 95th percentile of the US reference.Results One-quarter of preschool-aged children had early bedtimes (8:00 p.m. or earlier), one-half had bedtimes after 8:00 p.m. but by 9:00 p.m., and one-quarter had late bedtimes (after 9:00 p.m.). Children's bedtimes were similar regardless of maternal sensitivity (P = .2). The prevalence of adolescent obesity was 10%, 16%, and 23%, respectively, across early to late bedtime groups. The multivariable-adjusted relative risk (95% CI) for adolescent obesity was 0.48 (0.29, 0.82) for preschoolers with early bedtimes compared with preschoolers with late bedtimes. This risk was not modified by maternal sensitivity (P = .99).Conclusions Preschool-aged children with early weekday bedtimes were one-half as likely as children with late bedtimes to be obese as adolescents. Bedtimes are a modifiable routine that may help to prevent obesity.
