[目的]调查中学教师群体使用电脑情况及颈椎健康状况,分析使用电脑因素对颈椎发病的影响。[方法]编制《电脑使用者颈椎健康状况调查表》,对山东省某中学424名教师进行问卷调查,收集相关使用电脑及颈椎健康状况信息。将所有资料输入计算机以SPSS11.5软件进行统计分析,涉及多元Logistic回归分析、χ2检验、t检验及非参数相关分析。[结果]本次调查人群74.5%使用电脑频率≥4次/周,日均使用时间为(2.46±1.73)h,且男性在使用频率(P=0.000)和使用年限(P﹤0.05)上均明显高于女性,日均使用时间30岁以下年龄段明显高于30岁以上年龄段(P﹤0.05);颈椎病患病率为61.8%;单因素分析显示,性别、年龄、婚否、使用电脑频率、其余端坐时间、锻炼因素在颈椎病组与非颈椎病组差异有统计学意义;多因素Logistic回归分析结果显示,性别、婚否、使用电脑年限、日均使用时间、其余端坐时间为颈椎病致病的危险因素;非参数相关分析结果显示,婚否、使用电脑频率、使用电脑年限、日均使用时间与颈椎病具有相关性。[结论]中学教师是电脑使用群体,也是颈椎病高发人群,使用电脑频率、使用电脑年限、日均使用时间为颈椎病致病的电脑危险因素,并有显著意义。合理安排工作时间,设计并安装相关软件以提醒休息、控制电脑使用时间,是电脑使用者预防颈椎病的有效措施。
[Objective] To investigate the use of computer and cervical health in secondary school teachers and to analyze the influence of computer factors on the incidence of cervical spine. [Method] Compile Questionnaire of Cervical Spine Health of Computer Users, and conduct a questionnaire survey to 424 teachers of a middle school in Shandong Province, and collect information about the use of computer and cervical spine health status. All the data were input into the computer and SPSS11.5 software was used for statistical analysis, involving multiple logistic regression analysis, χ2 test, t test and nonparametric correlation analysis. [Results] The average frequency of use of computer in this survey population was 74.5% (≥4 times per week) and the average daily use time was (2.46 ± 1.73) h, and the average frequency of men (P = 0.000) and service life (P <0.05) (P <0.05); the prevalence of cervical spondylosis was 61.8%; univariate analysis showed that sex, age, marriage, use of Computer frequency, other sitting time, exercise factors in cervical spondylosis group and non-cervical spondylosis group differences were statistically significant; multivariate Logistic regression analysis showed that gender, marriage, use of computer age, average daily use time, the rest sitting The time was the risk factor of cervical spondylosis. The non-parametric correlation analysis showed that the frequency of marriage, the frequency of using the computer, the age of using the computer and the average daily using time were correlated with cervical spondylosis. [Conclusion] Middle school teachers are computer use groups and are also risk factors for PCOS patients with high frequency of cervical spondylosis, computer frequency, computer age and average daily use time. Reasonable arrangements for working hours, design and installation of related software to remind rest and control of computer use time, is the computer users to prevent cervical spondylosis effective measures.
