This study aimed to evaluate the longitudinal effect of dentition status on the perceived mobility limitation of community-dwelling Brazilian older adults. This cohort study used data from individuals who participated in the second (2006), third (2010), and fourth (2015) waves of the Health Well-being and Aging Study, conducted in the urban region of the city of São Paulo, Brazil, with adults aged 60 years and older. Mobility limitation was assessed in all waves according to reports of difficulty in performing seven activities, with higher scores representing a higher number of limitations. The independent variables of interest were number of teeth, use of dental prostheses, impact of oral health on functionality, and presence of periodontal pockets. Oral health measures were assessed by dentists, in all waves, during a clinical oral examination. The generalized linear mixed model with a Poisson distribution was used to assess longitudinal associations. All the variables were treated as time-varying in the analysis. Older adults with 20 or more teeth had a lower risk of mobility limitation than edentulous individuals, while the impact of oral health on functionality was associated with an increased risk. Similar findings were observed among dentate individuals. Periodontal disease was not associated with the outcome in dentate individuals. The associations were constant over time. The number of teeth and the impact of oral health on functionality are risk factors for mobility limitation, underscoring the importance of maintaining functional dentition for healthy aging.
本研究旨在评估牙列状况对巴西社区居住的老年人所感知的行动能力受限的纵向影响。这项队列研究使用了参与健康、幸福与老龄化研究第二轮（2006年）、第三轮（2010年）和第四轮（2015年）的数据，该研究在巴西圣保罗市的城市地区对60岁及以上的成年人进行。在所有轮次中，根据执行七项活动的困难程度报告来评估行动能力受限情况，得分越高表示受限数量越多。感兴趣的自变量包括牙齿数量、假牙使用情况、口腔健康对功能的影响以及牙周袋的存在情况。在所有轮次中，由牙医在临床口腔检查期间评估口腔健康指标。使用具有泊松分布的广义线性混合模型来评估纵向关联。在分析中，所有变量都被视为随时间变化的变量。牙齿数量为20颗或更多的老年人行动能力受限的风险低于无牙个体，而口腔健康对功能的影响与风险增加相关。在有牙个体中也观察到了类似的结果。在有牙个体中，牙周疾病与该结果无关。这些关联随时间保持不变。牙齿数量和口腔健康对功能的影响是行动能力受限的风险因素，这突出了保持功能性牙列对健康老龄化的重要性。
