Thirty-nine percent of 600 community-dwelling older Floridians (mean age of 78 yr) reported having mouth dryness. Seventy-nine percent of respondents reported at least one medical condition, 57% were taking at least one prescribed or over-the-counter medication, and 33% were taking at least one potentially xerostomic medication. Reported mouth dryness was highly associated with the number of potentially xerostomic medications. After stratification by medication usage, age, diabetes, arthritis, perceived medical health, and dependence in physical functioning were significantly associated with mouth dryness. Persons with dry mouth were also more likely to have reported dental symptoms, signs of dental disease, sensory changes, and other oral symptoms. Ten percent of those who reported mouth dryness also said that their mouths felt dry when eating a meal, 10% said that they had difficulties swallowing foods, and 15% of persons with dry mouth also said that the amount of saliva in their mouths was too little. Sixty-five percent of persons with dry mouth reported doing one or more dryness-related behaviors. These results suggest that the prevalence of xerostomia was high, and the impact of dry mouth on individuals' daily behaviors was significant.
在600名居住在社区的佛罗里达州老年人（平均年龄78岁）中，39%的人报告有口干症状。79%的受访者报告至少有一种疾病，57%的人正在服用至少一种处方药或非处方药，33%的人正在服用至少一种可能导致口干的药物。报告的口干与可能导致口干的药物数量高度相关。按用药情况分层后，年龄、糖尿病、关节炎、自我感知的健康状况以及身体功能依赖程度与口干显著相关。口干的人也更有可能报告有牙齿症状、牙病体征、感觉变化和其他口腔症状。报告有口干症状的人中有10%表示吃饭时嘴巴也会感到干，10%表示吞咽食物有困难，15%的口干者还表示口中唾液量过少。65%的口干者报告有一项或多项与口干相关的行为。这些结果表明，口干症的患病率很高，口干对个人日常行为的影响很大。
