The potential association between short sleep duration or sleep problems and childhood overweight has not been well described. The objective of this study was to test the independent associations of sleep duration and problems with overweight risk in children.
Data from the National Institute of Child Health and Human Development Study of Early Child Care and Youth Development were analyzed. In 3rd and 6th grades, sleep duration and problems were obtained by maternal report, and height and weight were measured, with overweight defined as a BMI of > or = 95th percentile for age and gender. Logistic regression evaluated the association of sleep duration and problems with overweight at 6th grade cross-sectionally adjusting for gender, race, and maternal education. Additional covariates tested individually included the level of chaos at home, the quality of the home environment, the lax-parenting subscale score of the Raising Children Checklist, and the Child Behavior Checklist internalizing and externalizing subscale scores. Logistic regression also evaluated the relationship of sleep duration at 3rd grade and overweight at 6th grade, adjusting for gender, race, maternal education, and the child's BMI z score in 3rd grade.
Of 785 children, 50% were male, 81% were white, and 18% were overweight in 6th grade. Shorter sleep duration in 6th grade was independently associated with a greater likelihood of overweight in 6th grade. Shorter sleep duration in 3rd grade was also independently associated with overweight in 6th grade, independent of the child's weight status in 3rd grade. Sleep problems were not associated with overweight.
One preventive approach to overweight may be to ensure adequate sleep in childhood.
睡眠时长较短或存在睡眠问题与儿童期超重之间的潜在关联尚未得到充分描述。本研究的目的是检验睡眠时长和睡眠问题与儿童超重风险之间的独立关联。
对来自美国国立儿童健康与人类发展研究所早期儿童保育与青少年发展研究的数据进行分析。在三年级和六年级时，通过母亲报告获取睡眠时长和睡眠问题信息，并测量身高和体重，超重定义为年龄和性别的BMI处于或高于第95百分位。逻辑回归分析在对性别、种族和母亲教育程度进行横断面调整的情况下，评估六年级时睡眠时长和睡眠问题与超重之间的关联。单独检验的其他协变量包括家庭混乱程度、家庭环境质量、《养育孩子清单》中宽松育儿子量表得分以及儿童行为清单内化和外化子量表得分。逻辑回归还评估了三年级时的睡眠时长与六年级时超重之间的关系，并对性别、种族、母亲教育程度以及三年级时儿童的BMI z评分进行了调整。
在785名儿童中，50%为男性，81%为白人，六年级时18%超重。六年级时较短的睡眠时长与六年级时超重的可能性增加独立相关。三年级时较短的睡眠时长也与六年级时超重独立相关，且与三年级时儿童的体重状况无关。睡眠问题与超重无关。
预防超重的一种方法可能是确保儿童期有充足的睡眠。
