This study explored the association between working hours and preventive oral health behaviors.
In total, 48,599 workers (22,992 females) were included from the Korea National Health and Nutrition Examination Survey (2007-2021). Weekly working hours were self-reported. The following three preventive oral health behaviors were set as outcomes: participation in annual dental check-ups; adherence to the recommended toothbrushing frequency (≥twice a day); and use of interdental cleaning devices. We estimated odds ratios (ORs) and 95% confidence intervals (CIs) using logistic regression.
In male workers, the adjusted OR (95% CI) of the association between working ≥55 h/week and each outcome was 0.84 (0.77-0.92) for dental check-ups, 0.82 (0.72-0.94) for toothbrushing ≥twice a day, and 0.83 (0.76-0.92) for utilization of interdental cleaning device when compared to 35-40 h/week. In female workers, the adjusted OR (95% CI) of the association between working ≥55 h/week and each outcome was 0.79 (0.70-0.89) for dental check-ups, 0.88 (0.70-1.11) for toothbrushing ≥twice a day, and 0.80 (0.71-0.90) for utilization of interdental cleaning device when compared to 35-40 h/week. Additionally, low socio-economic status, such as low educational attainment, low income level, and blue-collar occupations, were major risk factors associated with non-adherence to preventive oral health behaviors in both male and female workers.
Our study suggests that individuals who work long hours are more likely to exhibit undesirable oral health behaviors.
本研究探讨了工作时间与预防性口腔健康行为之间的关联。
本研究共纳入了来自韩国国家健康和营养检查调查（2007-2021 年）的 48599 名工人（22992 名女性）。每周工作时间由自我报告。将以下三种预防性口腔健康行为作为结果：参加年度牙科检查；坚持推荐的刷牙频率（每天≥两次）；使用牙间清洁器械。我们使用逻辑回归估计了比值比（OR）和 95%置信区间（CI）。
在男性工人中，与每周工作≥55 小时相比，每周工作 35-40 小时与每种结果的调整后 OR（95%CI）分别为：牙科检查 0.84（0.77-0.92），每天刷牙≥两次 0.82（0.72-0.94），使用牙间清洁器械 0.83（0.76-0.92）。在女性工人中，与每周工作≥55 小时相比，每周工作 35-40 小时与每种结果的调整后 OR（95%CI）分别为：牙科检查 0.79（0.70-0.89），每天刷牙≥两次 0.88（0.70-1.11），使用牙间清洁器械 0.80（0.71-0.90）。此外，低社会经济地位，如低教育程度、低收入水平和蓝领职业，是男性和女性工人中不遵守预防性口腔健康行为的主要危险因素。
我们的研究表明，工作时间长的人更有可能表现出不良的口腔健康行为。
