Various factors may be associated with edentulism in elderly people. Association of total tooth loss with smoking, alcohol intake and nutrition in non-institutionalised elderly Japanese was assessed utilising national database.
Records of independent surveys, the Survey of Dental Diseases (SDD) and the National Nutrition Survey (NNS) in 1999 were electronically linked using the household identification number.
Among the records of 6903 subjects in the SDD and 12 763 subjects in the NNS, 6805 records were successfully linked. Overall, prevalence of total tooth loss in adults was very similar in males and females at approximately 7.0%, and the smoking rate was 47.6% and 9.9% respectively. Total tooth loss was a rare phenomenon (<2%) in age groups of <60 years. According to the multiple logistic regression analysis involving 2200 subjects aged 60 years or older, significant variables were age, current smokers and vitamin C intake in males, and age and current smokers in females. The variable for current drinkers was significant in females but the odds ratio was <1.0. No significant relationship was detected with respect to former smokers and drinkers, body mass index, vitamin E intake and blood glucose level.
Current smoking was associated with total tooth loss, although smoking rate was low in females. Gender difference in the association was suggestive with respect to drinking alcohol and vitamin C intake.
多种因素可能与老年人无牙症相关。利用国家数据库评估日本非机构化老年人中全口牙缺失与吸烟、饮酒及营养状况之间的关联。
1999年的独立调查记录，即牙科疾病调查（SDD）和国家营养调查（NNS），使用家庭识别码进行电子链接。
在SDD的6903名受试者记录和NNS的12763名受试者记录中，6805条记录成功链接。总体而言，成年人全口牙缺失的患病率在男性和女性中非常相似，约为7.0%，吸烟率分别为47.6%和9.9%。在<60岁的年龄组中，全口牙缺失是一种罕见现象（<2%）。根据对2200名60岁及以上受试者进行的多因素逻辑回归分析，显著变量在男性中为年龄、当前吸烟者和维生素C摄入量，在女性中为年龄和当前吸烟者。当前饮酒者这一变量在女性中具有显著性，但比值比<1.0。未检测到与既往吸烟者、饮酒者、体重指数、维生素E摄入量和血糖水平之间的显著关系。
当前吸烟与全口牙缺失相关，尽管女性吸烟率较低。在饮酒和维生素C摄入量方面，这种关联存在性别差异。
