BACKGROUNDS Tooth loss is one of the major oral health problems among older Thai people. However, there is the existence of socioeconomic-related inequalities in dental service utilization, especially denture service. The aim of this study was to assess the determinants associated with inequalities in denture service utilization among older Thai people using the Andersen Behavioural model. METHOD This cross-sectional study involved secondary data analysis of the 2014 survey of older Thai people (N = 38,695). The dependent variable was a public denture service utilization over the past 5 years. Determinants were classified as predisposing and enabling factors. Predisposing variables included age, sex, education, economic condition and dependency status. Enabling variables included working status, health behaviours, health care utilization experience and social/community support. Data were analysed by using bivariate and multivariable analyses at α = 0.05. For bivariate analysis, chi-square test was used to determine the association between dependent and each independent variable. Then, all variables were incorporated into a multivariable binary logistic regression. RESULTS The odds of denture service utilization were significantly higher for individuals who were older, female, and had a higher educational level and health-promoting behaviors. A positive dose-response relationship was demonstrated between denture service utilization and increased quartile of household assets. CONCLUSIONS Predisposing variables had a greater impact than enabling variables in denture service utilization among older Thai people. Despite free public denture service, socioeconomic-related inequalities persist. The government needs to reduce socioeconomic disparities to improve denture treatment inequality.

与泰国老年人使用公共义齿服务相关的易感性和促成因素：一项基于人群的横断面研究。

背景技术牙齿脱落是泰国老年人中主要的口腔健康问题之一。但是，在牙科服务，尤其是义齿服务的使用中，存在与社会经济有关的不平等现象。这项研究的目的是使用Andersen行为模型评估泰国老年人中义齿服务使用不平等的决定因素。方法这项横断面研究涉及2014年泰国老年人（N = 38,695）的调查的辅助数据分析。因变量是过去5年中公共义齿服务的使用情况。决定因素被归类为诱发因素和促成因素。易变的变量包括年龄，性别，受教育程度，经济状况和依赖状况。启用变量包括工作状态，健康行为，卫生保健利用经验和社会/社区支持。通过在α= 0.05时使用双变量和多变量分析来分析数据。对于双变量分析，卡方检验用于确定因变量和每个自变量之间的关联。然后，将所有变量合并到多变量二元逻辑回归中。结果对于年龄较大，女性，文化程度较高和促进健康的行为，使用义齿服务的几率明显更高。假牙服务的利用与家庭资产四分位数的增加之间显示出正剂量反应关系。结论在泰国老年人中，易变因素的影响比使义齿服务利用中的因素具有更大的影响。尽管有免费的公共义齿服务，与社会经济有关的不平等现象仍然存在。政府需要减少社会经济差异，以改善义齿治疗的不平等。
