This study evaluates associations between oral health-related factors and chewing ability, and quantifies the risk contributed by each factor.
Chewing ability and information on number of teeth, dentures and dental problems over the last 12 months were collected by mailing questionnaires to a random sample of 60- to 71-year-olds from Adelaide, South Australia. Logistic regression was used to model oral status and oral symptoms as predictors of chewing disability, and to estimate the population-attributable fraction.
A total of 444 persons responded (response rate = 68.8%). Among dentate subjects, 10.3% were chewing-deficient, with chewing disability more prevalent (p < 0.05) among those with <21 teeth (26.4%), dentures (20.4%), painful aching in the mouth (25.4%), pain in the face (16.7%), broken/chipped teeth (15.6%), sensitive teeth (14.1%), loose teeth (37.1%), and sore gums (18.0%). Adjusted Odds ratios (OR) showed inadequate dentition (OR = 4.20), painful aching in the mouth (OR = 4.88), and presence of loose teeth (OR = 4.70) were associated with chewing disability (p < 0.01), and their population attributable fractions were 18.5%, 15.1% and 7.8% respectively.
Loose teeth, number of teeth and pain in the mouth were associated with chewing disability, with an inadequate dentition and pain in the mouth contributing most to chewing disability in this population.
本研究评估了口腔健康相关因素与咀嚼能力之间的关联，并量化了每个因素所带来的风险。
通过邮寄问卷的方式，向澳大利亚阿德莱德市随机抽取的 60 至 71 岁人群收集咀嚼能力以及过去 12 个月内的牙齿数量、假牙和牙齿问题信息。使用逻辑回归模型来模拟口腔状况和口腔症状作为咀嚼障碍的预测因子，并估算人群归因分数。
共有 444 人做出回应（回应率=68.8%）。在有牙人群中，10.3%的人存在咀嚼障碍，牙齿数量<21 颗（26.4%）、戴假牙（20.4%）、口腔疼痛（25.4%）、面部疼痛（16.7%）、牙齿断裂/缺损（15.6%）、牙齿敏感（14.1%）、牙齿松动（37.1%）和牙龈疼痛（18.0%）的人群中，咀嚼障碍更为常见（p<0.05）。调整后的优势比（OR）显示，牙齿不健全（OR=4.20）、口腔疼痛（OR=4.88）和牙齿松动（OR=4.70）与咀嚼障碍有关（p<0.01），其人群归因分数分别为 18.5%、15.1%和 7.8%。
牙齿松动、牙齿数量和口腔疼痛与咀嚼障碍有关，其中牙齿不健全和口腔疼痛对该人群的咀嚼障碍贡献最大。
