Abstract

Objectives: To determine the prevalence of edentulism and its rehabilitation in China's older population and describe socio-demographic differences in edentulism and rehabilitation.

Methods: Secondary analyses of the China Health and Retirement Longitudinal Study (CHARLS). Bivariate and regression analyses were performed.

Results: The weighted prevalence of edentulism was 26.0% (95% CI 24.8-27.2). Approximately two-thirds of edentulous elders had been rehabilitated (63.6%, 95% CI 57.4-69.4). In regression analyses, older people had a higher prevalence ratio (PR) for edentulism than younger elders: PR 3.0 (95% CI 2.7-3.4) for those aged 80 and older and PR 1.9 (95% CI 1.7-2.1) for those aged 70-79, with reference to those aged 60-69. Those who had attained secondary education had a lower PR for edentulism than those with no formal education: PR 0.7 (95% CI 0.6-0.8). Those from Non-Agricultural Hukou (Urban area) had a lower PR than those from Agricultural Hukou (Rural area): PR 0.8 (95% CI 0.7, 1.0). Older adults aged 80 and above were less likely to receive denture rehabilitation compared to those aged 60-69, with a PR of 0.6 (95% CI: 0.5-0.9). In contrast, individuals with secondary education showed a greater likelihood of denture rehabilitation than those without formal education, with a PR of 1.3 (95% CI: 1.0-1.6). Additionally, non-Han ethnic groups had a slightly higher chance of denture rehabilitation compared to their Han counterparts, with a PR of 1.2 (95% CI: 1.0-1.5).

Conclusions: Approximately one in four older people in China are edentulous, and approximately two in three of them have been rehabilitated. Socio-demographic differences in edentulism rates and rates of rehabilitation are apparent. These findings reveal disparities in edentulism and denture rehabilitation among China's older adults (60+), urging targeted policies to enhance access for less-educated and rural elders while offering insights for global ageing populations.

中国老年人的无牙主义及其康复。

目的：确定中国老年人口的牙牙病及其康复的患病率，并描述牙牙病和康复的社会人口差异。方法：对中国健康与退休纵向研究（CHARLS）进行二次分析。进行了双变量和回归分析。结果：全牙化加权患病率为26.0% （95% CI 24.8 ~ 27.2）。大约三分之二的无牙老年人得到了康复（63.6%,95% CI 57.4-69.4）。在回归分析中，老年人的牙髓病患病率（PR）高于年轻人：80岁及以上人群的PR为3.0 (95% CI 2.7-3.4)， 70-79岁人群的PR为1.9 (95% CI 1.7-2.1)，与60-69岁人群相比。接受过中等教育的人患蛀牙症的风险比没有接受过正规教育的人低：风险比为0.7 （95% CI 0.6-0.8）。非农业户口（城市地区）的PR低于农业户口（农村地区）的PR: PR为0.8 （95% CI 0.7, 1.0）。与60-69岁的老年人相比，80岁及以上的老年人接受假牙康复的可能性较小，PR为0.6 （95% CI: 0.5-0.9）。相比之下，受过中等教育的个体比没有受过正规教育的个体表现出更大的假牙康复的可能性，PR为1.3 （95% CI: 1.0-1.6）。此外，与汉族相比，非汉族群体的假牙康复机会略高，PR为1.2 （95% CI: 1.0-1.5）。结论：中国大约四分之一的老年人缺牙，其中大约三分之二的人已经康复。龋齿率和康复率的社会人口差异是明显的。这些研究结果揭示了中国老年人（60岁以上）在义齿治疗和义齿康复方面的差异，敦促制定有针对性的政策，提高受教育程度较低和农村老年人的获得机会，同时为全球老龄化人口提供见解。

期刊介绍： The ultimate aim of Gerodontology is to improve the quality of life and oral health of older people. The boundaries of most conventional dental specialties must be repeatedly crossed to provide optimal dental care for older people. In addition, management of other health problems impacts on dental care and clinicians need knowledge in these numerous overlapping areas. Bringing together these diverse topics within one journal serves clinicians who are seeking to read and to publish papers across a broad spectrum of specialties. This journal provides the juxtaposition of papers from traditional specialties but which share this patient-centred interest, providing a synergy that serves progress in the subject of gerodontology.
