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。
Objective To investigate the nocturnal sleep time and related factors of school-age children aged 6 ~ 12 in Zhongshan district of Guangdong province. Methods From 2005 to December 12, 2005, a total of 2012 school-aged children from 6 to 12 years old were selected from a primary school in Zhongshan City, Guangdong Province by random cluster analysis. Their parents were surveyed on social environment and sleep health among children and their families. As a result, 2012 questionnaires were sent out, and 1936 qualified questionnaires were recovered, with a recovery rate of 96.22%. The nighttime sleep time was generally (9.10 ± 0.57) h and (9.47 ± 0.81) h respectively in the school-age children of 6 ~ 12 years old, the difference was statistically significant (t = 16.437, P = 0.000) , The average nocturnal nocturnal sleep time decreased gradually in all age groups (1 year old and 6 age groups), which were 9.28h, 9.27h, 9.04h, 9.04h, 8.96h and 8.85h respectively. The result of multivariate stepwise regression analysis showed that the seven variables that parents thought children had enough time to sleep, children’s age, family size, fixed sleeping time, dependent’s sleeping time, often watching TV at night and father’s educational level were the most influential factors The main factors of nocturnal sleep time (r = 0.261, F = 60.683, P = 0.000). Conclusion Age and family social environment of school-age children aged 6-12 years are important influencing factors of nighttime sleep time. Parents should be aware of children’s sleep health.
