摘要：
Objective To explore the association between different visual display terminal use and physical symptoms among adults.Methods Hangzhou,Jiaxing,Huzhou,Jinhua and Quzhou City were selected,where residents aged 18 years old and above were investigated using Mitofsky-Waksberg two-stage sampling.Information of demography,different visual display terminal use,eye and musculoskeletal symptoms,eye disease and eye relax were collected.Backward stepwise logistic regression was used to explore the association between different visual display terminal use and the symptoms (P value for addition ＜ 0.05,P value for removal ＞ 0.1).Results Totally 350 adults responded to the investigation,with a response rate of 48.54％.Finally,333 respondents were included in the analysis,among which 120 reported eye symptoms (36.04％) and 71reported musculoskeletal symptoms (21.32％).More time of computer use at work(0.5-4 h:OR=2.006,95％ CI:1.021-3.943;4-6 h:OR=3.578,95％ CI:1.751-7.315;＞6 h:OR=4.874,95％ CI:1.897-12.521) and eye disease (OR =4.361,95％ CI:2.465-7.714) were significandy associated with higher odds ratios in eye symptoms.Similar pattern was seen for the association on time of computer use at work with musculoskeletal symptoms (0.5-4 h:OR =3.815,95 ％ CI:1.809-8.045;4-6 h:OR =4.974,95 ％ CI:2.281-10.845;＞ 6 h:OR =5.934,95％ CI:2.347-15.005).More time of watching TV on television (＞ 2 h:OR =2.051,95％CI:1.068-3.939) and women (OR =1.884,95％ CI:1.052-3.372) were also observed to be statistically associated with musculoskeletal symptoms.However,no statistical association was observed between the two symptoms and entertainment purpose use of computer/cell phone/pad/kindle (P ＞ 0.05).Conclusion Computer use at work was significantly associated with eye symptoms,especially for those having eye diseases.It was also statistically associated with musculoskeletal symptoms,especially for women.%目的 研究成人使用不同视频显示终端对其躯体症状的影响.方法 选取浙江省杭州市、嘉兴市、湖州市、金华市和衢州市5个城市,采用Mitofsky-Waksberg二阶段抽样方法,拨打住宅电话对≥18岁居民进行电话调查,内容包括人口学特征、眼部和骨骼肌肉症状及使用各种视频显示终端的情况.采用多因素Logistic回归模型分析使用不同视频显示终端对眼部和骨骼肌肉症状的影响.结果 共拨打固定电话号码3 464个,收集350份电话调查问卷,应答率为48.54％,拒访率为26.07％;对最终纳入的333份调查问卷进行统计分析.120名调查对象自述存在眼干、视物模糊、眼酸痛和流泪等眼部症状,占36.04％;71人自述存在骨骼肌肉症状,占21.32％.多因素Logistic回归分析结果显示,每天长时间使用电脑办公(0.5 ～4 h:OR=2.006,95％ CI:1.021～3.943;4～6h:OR=3.578,95％ CI:1.751～7.315;＞6h:OR=4.874,95％CI:1.897～12.521),近视、老花和白内障等视力障碍疾病(OR =4.361,95％ CI:2.465～7.714)是出现眼部症状的影响因素.长时间使用电脑办公(0.5～4 h:OR=3.815,95％ CI:1.809～8.045;4～6 h:OR=4.974,95％ CI:2.281～10.845;＞6h:OR=5.934,95％ CI:2.347～15.005)、长时间使用电视机娱乐(＞2 h:OR=2.051,95％ CI:1.068～3.939)和女性(OR=1.884,95％ CI:1.052～3.372)均是出现骨骼肌肉症状的影响因素.结论 长时间使用电脑办公是出现眼部症状的危险因素,尤其是视力障碍疾病患者;长时间使用电脑办公、长时间使用电视机娱乐和女性是骨骼肌肉症状的危险因素.
