ABSTRACT
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.
