Abstract: Objective To preliminarily explore the correlation between fatty liver and sleep quality in adolescents in Shanghai. Method A total of 1 121 students from Shanghai completed Adolescent Sleep Quality Questionnaire and had their liver fatty content measured with FibroScan. Results The detection rate of fatty liver in all adolescents was 9.01% (101/1 121), with no significant difference between genders [male:8.84%(49/554), female:9.17%(52/567), χ²=0.03, P>0.05].The detection rate of poor sleep quality in all adolescents was 21.05% (236/1 121), with no significant gender difference [(male:21.48%(119/554), female:20.63%(117/567),χ²=0.07, P>0.05)].The detection rate of poor sleep quality was 25.74% in 101 students with fatty liver and 20.59% in 1 020 students without fatty liver, but it was not significantly different (χ²=0.93, P>0.05). Moreover, there were no significant differences on subjective sleep quality, sleep duration, sleep effect and daytime dysfunction between students with and without fatty liver(P>0.05). Conclusion The inter-relationship between fatty liver and sleep quality in adolescents in Shanghai needs to be further studied.

摘要： 目的 探索上海青少年脂肪肝与睡眠质量之间的相关性。方法 2019年5月,上海1 121名中学生被用FibroScan瞬时弹性记录仪完成肝脂肪变程度测定及自行完成青少年睡眠质量流行病学调查表填写。结果 青少年脂肪肝检出率为9.01%(101/1 121),其中男生8.84%(49/554),女生为9.17%(52/567),男女生之间差异无统计学意义(χ²=0.03, P>0.05);经校正分层因素影响后,睡眠质量差检出率为21.05%(236/1 121),其中男21.48%(119/554),女20.63%(117/567),男女之间差异无统计学意义(χ²=0.07, P>0.05)。101名脂肪肝学生中睡眠质量差检出率为25.74%, 1 020名非脂肪肝学生中睡眠质量差检出率为20.59%,但两组之间差异无统计学意义(χ²=0.93,P>0.05)。脂肪肝学生与非脂肪肝学生在主观睡眠质量、时间、效应及日间功能障碍方面差异均无统计学意义(P>0.05)。结论 上海青少年脂肪肝与睡眠质量之间相关性有待进一步研究。
