Eating out of home (EOH), with its diverse food options, can benefit those with difficulty preparing their meals, especially older adults. Oral health status may be a determinant of EOH, as food accessibility is influenced by oral health, but this association remains unclear. This cross-sectional study used merged data from two national statistical surveys conducted in 2019. Participants were individuals aged ≥ 65 years who responded to both surveys. The frequency of EOH (<once/week or ≥once/week) was the dependent variable. The number of teeth was used as the independent variable (≥20, 10-19, 1-9, and 0). Prevalence ratios (PRs) and 95% confidence intervals (CIs) were calculated using multivariate Poisson regression analysis to identify the association between EOH and the number of teeth, adjusting for possible confounders. We analyzed 2164 participants (mean age = 74.0, women 52.4%). Of these, 456 (21.1%) participants were EOH ≥ once/week; 1142 (52.8%) participants had ≥20 teeth. Compared to those with ≥20 teeth, those with <20 teeth had a lower prevalence of EOH ≥ once/week (10-19: PR = 0.89, 95% CI = 0.72-1.09, 1-9: PR = 0.67, 95% CI = 0.51-0.89, and 0: PR = 0.53, 95% CI = 0.36-0.77, respectively). We observed an association between fewer teeth and a lower frequency of EOH.
外出就餐（EOH）提供了多样化的食物选择，可能对那些难以准备餐食的人，特别是老年人有益。口腔健康状况可能是 EOH 的决定因素，因为食物的可及性受到口腔健康的影响，但这种关联尚不清楚。本横断面研究使用了 2019 年两项全国性统计调查的合并数据。参与者为年龄≥65 岁并对两项调查均作出回应的个体。EOH 的频率（<每周一次或≥每周一次）是因变量。牙齿数量被用作自变量（≥20、10-19、1-9 和 0）。使用多变量泊松回归分析计算患病率比（PR）和 95%置信区间（CI），以确定 EOH 与牙齿数量之间的关联，同时调整可能的混杂因素。我们分析了 2164 名参与者（平均年龄=74.0 岁，女性占 52.4%）。其中，456 名（21.1%）参与者 EOH≥每周一次；1142 名（52.8%）参与者有≥20 颗牙齿。与拥有≥20 颗牙齿的参与者相比，牙齿数量较少的参与者 EOH≥每周一次的患病率较低（10-19：PR=0.89，95%CI=0.72-1.09；1-9：PR=0.67，95%CI=0.51-0.89；0：PR=0.53，95%CI=0.36-0.77）。我们观察到牙齿数量较少与 EOH 频率较低之间存在关联。
