To examine the relationship between edentulousness and the socioeconomic and behavioural variables collected in a cross-sectional study of an elderly population.
The study was conducted on 277 elderly (60 years or older) in the municipality of Biguaçu, Southern Brazil. The oral examinations and questionnaires were conducted by two calibrated dentists. The criteria used followed the WHO and FDI standards.
Prevalence of edentulousness reached 48.4%. A significant association was found in bivariate analysis for gender, satisfaction with appearance, time since last dental visit, the type of dental service sought in the last 5 years, educational level of the elderly and their children, and age of the elderly. In the multivariate analysis, gender, time since last dental visit and level of education of the elderly were significantly associated with edentulousness.
Female sex and low educational level were the main risk factors for edentulousness in this population. Although various Brazilian studies suggest a decline in edentulousness in the country, methodologically robust research into edentulousness in Brazil is still limited, demanding further studies into this highly prevalent yet preventable health problem amongst the elderly.
在一项针对老年人群的横断面研究中，考察无牙状况与所收集的社会经济和行为变量之间的关系。
该研究在巴西南部比瓜苏市的277名老年人（60岁及以上）中开展。口腔检查和问卷调查由两名经过校准的牙医进行。所采用的标准遵循世界卫生组织（WHO）和国际牙科联合会（FDI）的标准。
无牙状况的患病率达到48.4%。在双变量分析中，发现性别、对外表的满意度、上次看牙以来的时间、过去5年寻求的牙科服务类型、老年人及其子女的教育水平以及老年人的年龄之间存在显著关联。在多变量分析中，性别、上次看牙以来的时间以及老年人的教育水平与无牙状况显著相关。
女性和低教育水平是该人群无牙状况的主要危险因素。尽管巴西的各项研究表明该国无牙状况有所下降，但对巴西无牙状况进行方法学上稳健的研究仍然有限，需要对这一在老年人中高度普遍且可预防的健康问题开展进一步研究。
