背景资料：许多因素影响老年人的牙齿脱落，包括吸烟;然而，关于吸烟与成年早期牙齿脱落之间关系的证据有限。本研究探讨吸烟和牙齿脱落的经验之间的关联，年龄在20 - 39岁的成年人使用的两个国家databases.Methods：两个数据库的全国营养调查（NNS）和牙科疾病的调查（SDD），这是在1999年进行的，从卫生，劳动和福利部获得的分析使用许可。在NNS中，参与者接受了体检，并就饮食摄入和健康习惯（包括吸烟）进行了访谈，而在SDD中，参与者被问及他们每天刷牙的频率，并接受了认证牙医的口腔检查。在通过家庭识别码电子链接的6，805份记录中，分析了1，314份年龄在20至39岁之间的个人记录。比较了非吸烟者、前吸烟者和当前吸烟者的1+牙缺失患病率。多元Logistic回归模型的构建包括混杂因素：刷牙频率，体重指数，饮酒量，维生素C和E的摄入量。结果：吸烟率在男性（53.3%）和女性（15.5%）有很大差异。牙齿脱落的总患病率为31.4%（男性31.8%，女性31.1%）。目前吸烟者（40.6%）比以前吸烟者（23.1%）和非吸烟者（27.9%）更经常发生牙齿脱落。目前吸烟与男性（调整OR = 2.21 [1.40 - 3.50]，P = 0.0007）和女性（1.70 [1.13 - 2.55]，P = 0.0111）的1+牙缺失显著相关。吸烟状况与牙齿脱落之间存在显著的正相关关系（男性和女性的趋势P分别< 0.0001和0.0004）。目前吸烟也与龋齿患病率相关（1.67 [1.28 -2.20]，P = 0.0002）。结论：在日本各地的年轻人中，吸烟与牙齿脱落之间的关联是明显的。由于现有数据库中可用变量的局限性，应进行包括龋齿经历及其混杂因素在内的进一步研究，以检查吸烟是否是年轻人牙齿过早脱落的真正风险。
Background: Various factors affect tooth loss in older age including cigarette smoking; however, evidence regarding the association between smoking and tooth loss during young adulthood is limited. The present study examined the association between cigarette smoking and tooth loss experience among adults aged 20 -39 years using linked data from two national databases in Japan.Methods: Two databases of the National Nutrition Survey (NNS) and the Survey of Dental Diseases (SDD), which were conducted in 1999, were obtained from the Ministry of Health, Labor and Welfare with permission for analytical use. In the NNS, participants received physical examinations and were interviewed regarding dietary intake and health practices including cigarette smoking, whereas in the SDD, participants were asked about their frequency of daily brushing, and received oral examinations by certified dentists. Among 6,805 records electronically linked via household identification code, 1314 records of individuals aged 20 to 39 years were analyzed. The prevalence of 1+ tooth loss was compared among non-, former, and current smokers. Multiple logistic regression models were constructed including confounders: frequency of tooth brushing, body mass index, alcohol consumption, and intake of vitamins C and E.Results: Smoking rates differed greatly in men (53.3%) and women (15.5%). The overall prevalence of tooth loss was 31.4% (31.8% men and 31.1% women). Tooth loss occurred more frequently among current smokers (40.6%) than former (23.1%) and non-smokers (27.9%). Current smoking showed a significant association with 1+ tooth loss in men (adjusted OR = 2.21 [1.40 -3.50], P = 0.0007) and women (1.70 [1.13 -2.55], P = 0.0111). A significant positive exposure-related relationship between cigarette smoking status and tooth loss was observed (P for trend < 0.0001 and 0.0004 in men and women, respectively). Current smoking was also associated with the prevalence of decayed teeth (1.67 [1.28 -2.20], P = 0.0002).Conclusion: An association between cigarette smoking and tooth loss was evident among young adults throughout Japan. Due to limitations of the available variables in the present databases, further studies including caries experience and its confounders should be conducted to examine whether smoking is a true risk of premature tooth loss in young adults.
