To examine the association between rheumatoid arthritis (RA) and oral hypofunction (OHF) using propensity score matching (PSM) to adjust for differences between older adults with RA and the general older adult population.
We conducted a cross-sectional survey among 189 older adults with RA in 2019 (mean age, 71.9 ± 3.6) and 47 178 independent older adult residents in 2016 (mean age, 71.6 ± 4.0), respectively. The questionnaire covered information on socio-demographic characteristics and OHF for both groups. Age, sex, educational level and smoking history were used to determine PSM. Prevalence ratios (PRs) and 95% confidence intervals (CIs) of self-reported OHF (fewer remaining teeth, decreased masticatory function, deterioration of swallowing function and oral dryness) were estimated using Poisson regressions.
OHF was observed in 44.4% of patients with RA and 27.5% of residents. Before PSM, the prevalence of OHF among patients with RA was higher than that of residents (PR, 1.75; 95% CI, 1.50-2.05). After PSM, there were 189 patients with RA and residents, and the prevalence of OHF among patients with RA was still higher (PR, 1.61; 95% CI, 1.22-2.13). Poisson regression showed that the prevalence of 19 or fewer teeth (PR, 1.06; 95% CI, 0.82-1.36), difficulties eating tough foods (PR, 1.18; 95% CI, 0.90-1.55), difficulties swallowing tea or soup (PR, 1.77; 95% CI, 1.19-2.63), and dry mouth (PR, 2.79; 95% CI, 1.90-4.07) was higher among patients with RA than residents.
Compared with the general older adult population, patients with RA have a higher prevalence of self-reported OHF.
通过倾向评分匹配（PSM）调整类风湿关节炎（RA）老年患者与普通老年人群之间的差异，探讨 RA 与口腔功能低下（OHF）的关系。
我们于 2019 年对 189 名 RA 老年患者（平均年龄 71.9±3.6 岁）和 2016 年 47178 名独立的普通老年居民（平均年龄 71.6±4.0 岁）进行了横断面调查。问卷涵盖了两组人群的社会人口学特征和 OHF 信息。采用年龄、性别、教育水平和吸烟史进行 PSM。采用泊松回归估计自我报告 OHF（剩余牙齿较少、咀嚼功能下降、吞咽功能恶化和口腔干燥）的患病率比（PR）和 95%置信区间（CI）。
RA 患者的 OHF 发生率为 44.4%，居民为 27.5%。PSM 前，RA 患者的 OHF 发生率高于居民（PR，1.75；95%CI，1.50-2.05）。PSM 后，RA 患者和居民各 189 名，RA 患者的 OHF 发生率仍较高（PR，1.61；95%CI，1.22-2.13）。泊松回归显示，牙齿数为 19 颗或更少（PR，1.06；95%CI，0.82-1.36）、难以进食坚硬食物（PR，1.18；95%CI，0.90-1.55）、难以吞咽茶水或汤（PR，1.77；95%CI，1.19-2.63）和口干（PR，2.79；95%CI，1.90-4.07）的发生率在 RA 患者中均高于居民。
与普通老年人群相比，RA 患者自我报告 OHF 的发生率更高。
