青少年超重肥胖与睡眠质量的相关性

Relationship between overweight and sleep quality in adolescents

目的探讨上海市虹口区肥胖及超重青少年与睡眠质量之间的相关性,为制定促进青少年身心健康措施提供参考。方法随机抽取上海市虹口区4所初中及高中的1 173名中学生测量身高、体重,采用青少年睡眠质量流行病学调查表进行问卷调查。结果男、女生肥胖、超重及肥胖+超重的检出率差异无统计学意义(P值均>0.05)。经校正分层因素影响后,中学生睡眠质量差的检出率为18.84%,男、女生差异无统计学意义。经校正分层因素影响后的初中及高中学生睡眠质量差的检出率分别为13.43%,26.85%,差异有统计学意义(χ2=22.290,P<0.05)。在358名肥胖+超重学生中,睡眠质量差的检出率(37.25%)高于正常体重学生检出率(10.80%),差异有统计学意义(χ2=71.706,P<0.05)。结论青少年肥胖及超重可能与差的睡眠质量有较大关系,好的睡眠质量及充足的睡眠时间可能有效预防青少年肥胖及超重,还需有待今后的随访加以证实。

Objective To explore the relationship between overweight and sleep quality in adolescents. Methods Totally1 173 students in Shanghai were recruited to complete adolescent sleep quality questionnaire. Body mass index and height were calculated. Results There was no significant gender difference in the prevalence of obesity and overweight（ P〈0. 05）. Nearly one in fifth（ 18. 84%） of students reported poor sleep quality. The prevalence of poor sleep quality adjusted for cluster effects in senior middle school students（ 26. 85%） was higher than that of junior high school students（ 13. 43%）（ χ2= 22. 290,P〈0. 05）. About37. 25% of overweight / obese adolescents reported poor sleep,which was higher than that of normal weight peers（ 10. 80%）. Obesity / overweight students had significantly poor sleep quality,short sleep duration and daytime dysfunction（ χ2= 71. 706,P〈0.05）. Conclusion Overweight / obesity significantly correlated with poor sleep quality among adolescents. Further research is needed to examine whether high-quality and sufficient sleep duration could prevent obesity in adolescents.
