The aim of this study was to investigate the association between work-related factors and temporomandibular disorders (TMD) among female full-time employees using representative data from a national population-based survey.
Data from the Fourth Korea National Health and Nutrition Examination Survey IV (2007-2009) were used to analyze 1,612 women. Complex samples logistic regression was applied for adjusting for general characteristics and work-related factors to examine the association between work-related factors and TMD.
The prevalence of TMD was 12.8% in this study population. With respect to age, educational status, marital status, problem drinking, exercise, and stress, there were statistically significant differences in the prevalence of TMD. In logistic regression analyses on complex samples, based on 40 h or less per week, odds ratios (ORs) for respondents who worked 40-48 working hours, 49-60 working hours, and more than 60 h were 1.16 (95% confidence interval (CI) 0.69-1.94), 1.41 (95% CI 0.79-2.54), and 2.43 (95% CI 1.29-4.59), after adjusting for general characteristics, working schedule, employment status, and occupation.
This study found that long working hours were significantly associated with TMD in Korean female full-time employees.
本研究旨在利用全国性人群调查的代表性数据，调查女性全职员工中与工作相关的因素和颞下颌关节紊乱症（TMD）之间的关联。
使用韩国第四次全国健康与营养检查调查IV（2007 - 2009年）的数据对1612名女性进行分析。采用复杂样本逻辑回归分析来调整一般特征和与工作相关的因素，以检验与工作相关的因素和TMD之间的关联。
本研究人群中TMD的患病率为12.8%。在年龄、教育程度、婚姻状况、问题饮酒、运动和压力方面，TMD的患病率存在统计学显著差异。在复杂样本的逻辑回归分析中，以每周工作40小时及以下为基础，在调整了一般特征、工作时间表、就业状况和职业后，每周工作40 - 48小时、49 - 60小时和超过60小时的受访者的优势比（OR）分别为1.16（95%置信区间（CI）0.69 - 1.94）、1.41（95%CI 0.79 - 2.54）和2.43（95%CI 1.29 - 4.59）。
本研究发现，长时间工作与韩国女性全职员工的TMD显著相关。
