儿童睡眠时间与肥胖或超重相关性及影响因素的研究进展

The research progress of the correlation between sleep time and obesity or overweight and influencing factors on children

通过对儿童睡眠时间与肥胖或超重的关系及影响因素的研究进行综述,分析儿童睡眠时间与肥胖或超重的相关性及其关联因素。国内外大部分研究证实了儿童睡眠时间的减少与肥胖或超重具有一定相关性,但具体呈现怎样的相关性尚无定论。瘦素、食欲素、胃饥饿素水平和个人行为习惯可在睡眠时间减少与肥胖或超重的相关性中起到一定的关联作用,但目前的研究结果尚不能解释变量之间的因果关系。儿童睡眠时间与肥胖或超重是否存在确切的因果关系、起到关联作用的因素在睡眠时长与肥胖或超重之间具体的关联作用及作用程度仍需更多纵向的描述性及干预性研究来验证。

The relationship between children’s sleep time and obesity or overweight and the influencing factors were reviewed to analyze the correlation between children’s sleep time and obesity or overweight and the related factors.Most studies at home and abroad have confirmed that the reduction of sleep time in children has a certain correlation with obesity or overweight,but the specific correlation has not been determined.Leptin,orexins,ghrelin levels and individual behavior play a role in the correlation between reduced sleep time and obesity or overweight,but the current findings do not explain the causal relationship between the variables.Whether there is an exact cause-and-effect relationship between sleep time and obesity or overweight in children,and the specific correlation between the length of sleep and obesity or overweight and the extent of the related factors still need more longitudinal descriptive and interventional studies to verify.
