The aim of this study was to investigate the associated factors of changes in symptoms of xerostomia (SOX) in adults aged 20-59.
A prospective population-based study was conducted in 2009 (n = 1720) and 2012 (n = 1222) in the urban area of Florianópolis, SC, Brazil. Information on SOX was collected in both years together with age, family income, years of schooling, smoking habit, alcohol consumption, changes in the body mass index (BMI; kg/m²), medicine use, self-reported diagnosis of chronic diseases, change in hypertension status and in the use and need for dentures, and number of remaining teeth. Associated factors with changes in SOX were investigated using multinomial logistic regression, considering those who had never reported this symptom as the reference.
Prevalence of regular SOX was equal to 3.8% (95% CI: 2.9-5.1) and irregular (one period only) equal to 12.2% (95% CI: 10.2-14.5). Age, smoking habit, medicine use, self-reported diagnosis of depression, and weight gain increased the probability of regular SOX, whereas highest schooling level was associated with lower probability of this symptom.
General and psychosocial health influenced the number of episodes of xerostomia symptoms, calling for multidisciplinary actions to prevent common risk behaviors for oral and general diseases.
本研究旨在调查20至59岁成年人口干症状（SOX）变化的相关因素。
2009年（n = 1720）和2012年（n = 1222）在巴西圣卡塔琳娜州弗洛里亚诺波利斯市区进行了一项基于人群的前瞻性研究。在这两年中收集了有关SOX的信息，以及年龄、家庭收入、受教育年限、吸烟习惯、饮酒情况、体重指数（BMI；kg/m²）变化、用药情况、自我报告的慢性病诊断、高血压状况变化以及假牙的使用和需求，还有剩余牙齿数量。使用多项逻辑回归研究与SOX变化相关的因素，将从未报告过该症状的人作为参照。
经常出现SOX的患病率为3.8%（95%可信区间：2.9 - 5.1），偶尔出现（仅一个时期）的患病率为12.2%（95%可信区间：10.2 - 14.5）。年龄、吸烟习惯、用药情况、自我报告的抑郁症诊断以及体重增加会增加经常出现SOX的可能性，而最高学历水平与出现该症状的可能性较低相关。
总体健康和心理社会健康会影响口干症状的发作次数，需要采取多学科行动来预防口腔疾病和一般疾病的常见风险行为。
