PURPOSE To explore the association between xerostomia and dry eye symptoms in the older adult population. METHODS Secondary analysis of data from 627 participants (346 male, 291 female), with a mean ± SD age of 75 ± 7 years, recruited through the population-based South Australian Dental Longitudinal Study. Participants completed the validated Summated Xerostomia Inventory-Dutch Version questionnaire (SXI-D), and rated their overall frequency of dry eye symptoms at baseline. RESULTS Symptomatic dry eye was reported by 31% of participants, and xerostomia by 21%. A positive correlation was observed between dry eye symptoms and SXI-D scores (Spearman's rho = +0.379, p < 0.001). Overall, participants with symptomatic dry eye had higher SXI-D scores than those without (10.6 ± 3.6 vs. 8.1 ± 2.8, p < 0.001), and were more likely to report xerostomia, with an odds ratio (95% CI) of 2.25 (1.52-3.35; p < 0.001). CONCLUSIONS Symptoms of xerostomia and dry eye were relatively common in the cohort of older adult participants. The potentially debilitating implications of - and positive association between - the two types of sicca symptoms support the routine evaluation of xerostomia symptoms as part of the assessment of dry eye patients, and vice versa.

老年人口干症与干眼症之间的关联。

目的探讨老年人口干口症与干眼症状之间的关系。方法通过基于人群的南澳大利亚州牙齿纵向研究，对来自627名参与者（346名男性，291名女性）的数据进行二次分析，平均年龄±SD年龄为75±7岁。参与者完成了经过验证的“干燥口干库存-荷兰语”问卷（SXI-D），并评估了他们在基线时干眼症状的总体发生频率。结果31％的参与者报告了有症状的干眼症，而口干症的报告率为21％。在干眼症状和SXI-D评分之间观察到正相关（Spearman的rho = + 0.379，p <0.001）。总体而言，有症状干眼的参与者的SXI-D评分高于无症状参与者（10.6±3.6 vs. 8.1±2.8，p <0.001），且更容易报告口干症，比值比（95％CI）为2.25（1.52-3.35； p <0.001）。结论口干和干眼症的症状在成年参与者中相对普遍。两种类型的干燥症状之间的潜在关联以及它们之间的正相关关系，都支持对口干症症状进行常规评估，这是干眼患者评估的一部分，反之亦然。
