摘　　要：目的分析7~18岁儿童青少年电子设备使用时长与体重过度感知之间的关联,为儿童青少年体重过度感知的合理干预提供科学依据。方法利用2012年卫生行业公益性科研专项资料,采用分层整群随机抽样,选择中国的7个省(市)中信息完整的40073名儿童青少年,使用有序多分类Logistic回归分析电子设备使用时长与儿童青少年体重过度感知的关联。结果儿童青少年体重过度感知的报告率为11.8%;体重过度感知组每天使用电子设备超过300 min的比例(5.12%)高于非过度感知组(3.84%)(χ^(2)=19.14,P<0.01)。单因素分析显示,电子设备使用时长>300 min的儿童青少年出现体重过度感知的风险更大(OR=1.36,95%CI=1.18~1.57,P<0.01);多因素调整后,该关联仍有统计学意义(OR=1.28,95%CI=1.10~1.48,P<0.05)。分层分析后,电子设备使用时长与体重过度感知之间的关联仅在女生、11~18岁年龄组和非独生子女组中具有统计学意义(P值均<0.05)。结论电子设备使用时长与儿童青少年体重过度感知相关,减少电子设备使用时长可能有助于改善该人群中体重过度感知问题。Objective To explore the association between digital devices usage and body weight overestimation in children and adolescents aged 7-18,in order to provide a scientific basis for body weight overestimation prevention in children and adolescents.Methods Based on the data of the Research Special Project for Public Welfare Industry of Health using stratified cluster sampling method in 2012,a tatal of 40073 children and adolescents from 7 provinces with complete information were chosen.Ordinal multivariable Logistic regression model estimated the association between digital devices usage and body weight overestimation.Results A total of 4276(11.8%)students with overestimation of body weight were detected,who spent>300 min/d time in digital devices(5.12%)than others(3.84%)(χ^(2)=19.14,P<0.01).Univariate analysis showed that students with time spent on digital devices>300 min/d had a higher risk in overestimation of body weight(OR=1.36,95%CI=1.18-1.57,P<0.01)compared with students who spent on digital devices≤120 min/d.There was still a significant association after confounder adjustment(OR=1.28,95%CI=1.10-1.48,P<0.05).Stratified analysis showed that the association between digital devices usage and overestimation of body weight were only observed in girls,11-18 years old and non-single child(P<0.05).Conclusion The time usage of digital devices is associated with overestimation of body weight in children and adolescents.It may helpful for children and adolescents to prevent overestimation of body weight by reducing time spent on digital devices.
