目的探讨广东省中山地区某小学6~12岁学龄儿童的夜间睡眠时间及其相关因素。方法2005-11-12,随机整群抽取广东省中山市城区某小学6~12岁全部学生,共2012名学龄儿童,对其家长进行儿童家庭社会环境与睡眠健康问卷调查。结果发出调查问卷2012份,结果回收合格问卷1936份,回收率96.22%。6~12岁学龄儿童的夜间睡眠时间平时为(9.10±0.57)h,周末为(9.47±0.81)h,两者比较差异有极显著性意义(t=16.437,P=0.000);随着年龄的增长,各年龄组(相差1岁分组,共6个年龄组)儿童平时的夜间睡眠时间逐渐减少,依次为9.28h、9.27h、9.04h、9.04h、8.96h、8.85h。多元逐步回归分析结果表明父母认为孩子睡眠时间足够、儿童的年龄、家庭人口数、有固定的睡眠时间、抚养人的睡眠时间、常常晚上看电视入睡、父亲文化教育程度等7个变量是影响儿童平时夜间睡眠时间的主要因素(r=0.261,F=60.683,P=0.000)。结论6~12岁学龄儿童的年龄、家庭社会环境是其夜间睡眠时间的重要影响因素,应提高家长对儿童睡眠健康的认识。

Study of nighttime sleep in children aged 6 to 12 years in Zhongshan city.

?? AbstractObjectiveTo investigate nighttime sleep in children aged 6 to 12 years in Zhongshan city,and identify related factors to nighttime sleep. MethodsFrom November to December of 2005,2012 children in one school,aged 6 to 12 years,were investigated with questionnaire about children's social environment and sleep condition in Zhongshan city. ResultsActually 1936 children(1043 boys,893 girls)were investigated.The average time of nighttime sleep in 6~12 year-old children was (9.10??0.57)hours in regular time,and (9.47??0.81)hours at weekend(t=16.437??P=0.000).With the age increasing,the time of nighttime sleep in regular time decreased gradually,being 9.28h,9.27h,9.04h,9.04h,8.96h and 8.85h in 6,7,8,9,10 and 11-year old children.But the time of nighttime sleep in these children at weekends was not significantly different.Children's sleep time was affected mainly by 7 main factors:parents consideration of whether their sleep time was enough or not,children's age,the population number in the family,children's sleep time being regular,fosters' sleep time,frequently falling asleep while watching TV,father??s education degree(r=0.261??F=60.683??P=0.000). ConclusionThe nighttime sleep in children aged 6 to 12 years in Zhongshan city is less than foreign countries.Children??s age and family social environment are the main affecting factors.To ensure the children??s health,the parent??s knowledge of sleeping in the children must be improved.
