We aimed to investigate the association between long working hours and periodontitis, and whether such an association constitutes an exposure-response relationship. Data for this study were collected from the Korea National Health and Nutrition Examination Surveys conducted from 2007 to 2014; 17,533 workers (9,483 of men and 8,050 of women) were included. The odds ratios (OR) and 95% confidence intervals (CI) for the analysis of periodontitis defined as positive of Community Periodontal Index in relation to working hours were calculated using multiple logistic regression models with various stratifications. Compared to participants who worked ≤40 hours per week, the prevalence ratio (95% CI) for the periodontitis was 1.19 (1.14-1.24) and full adjusted OR (95% CI) was 1.09 (1.02-1.18) in participants who worked over 40 hours per week. The OR (95% CI) for periodontitis were 1.09 (0.99-1.19) in working group of 40< and ≥52 and 1.10 (1.01-1.20) in working group of >52 hours per week with a significant trend (p = 0.0233) even after adjusting for age, socioeconomic status, healthy behaviour, chronic disease, and dental care status. Long working hours are associated with periodontitis among Korean workers in an exposure-response manner.
本研究旨在探讨长时间工作与牙周炎之间的关联，以及这种关联是否构成暴露-反应关系。本研究的数据来自于 2007 年至 2014 年进行的韩国国家健康和营养调查；共纳入 17533 名工人（男性 9483 名，女性 8050 名）。使用多因素逻辑回归模型，通过不同分层，计算了社区牙周指数阳性与工作时间之间的牙周炎比值比（OR）和 95%置信区间（CI）。与每周工作≤40 小时的参与者相比，每周工作超过 40 小时的参与者的牙周炎患病率比（95%CI）为 1.19（1.14-1.24），完全调整后的 OR（95%CI）为 1.09（1.02-1.18）。对于每周工作 40<和≥52 小时的工作时间组，牙周炎的 OR（95%CI）为 1.09（0.99-1.19），每周工作时间>52 小时的工作时间组为 1.10（1.01-1.20），呈显著趋势（p=0.0233），即使在调整了年龄、社会经济状况、健康行为、慢性病和口腔保健状况后也是如此。长时间工作与韩国工人的牙周炎呈暴露-反应关系。
