Objective-to-clearance the association of tooth loss with dietary intakes among dentists，for whom enough dental care is available.Methods：我们分析了20366名日本牙医（平均年龄+/- SD，52.2 +/- 12.1岁;女性8.0%）的数据，他们参加了2001年至2006年的一项全国性队列研究。基线调查问卷包括一个经过验证的食物频率调查问卷，以估计食物和营养素的摄入量。我们计算了几何平均每日摄入量的牙齿数量，调整年龄，性别，吸烟，体力活动，和糖尿病的历史。结果：一些关键的营养素和食物组，如胡萝卜素，维生素A和C，牛奶和乳制品，蔬菜，包括绿色，黄色蔬菜的平均摄入量，随着牙齿脱落的数量增加而下降（P趋势< 0.05）。相反，在牙齿较少的人群中，碳水化合物、大米和蔬菜的平均摄入量增加（趋势P < 0.05）。完全无牙受试者和牙齿≥ 25颗受试者之间的几何平均值（%）差异，即[（≥ 25颗牙齿的几何平均值）-（0颗牙齿的几何平均值）]/（≥ 25颗牙齿的几何平均值）x 100，胡萝卜素、维生素C、维生素A和碳水化合物的几何平均值分别为14.3%、8.6%、6.1%和-6.1%。在食物组中，牛奶和乳制品、绿黄色蔬菜、总蔬菜、大米和蔬菜的患病率分别为26.3%、11.9%、5.6%、-9.5%和-29.6%。
Objectives:To clarify the association of tooth loss with dietary intakes among dentists, for whom sufficient dental care is available.Methods:We analyzed the data from 20 366 Japanese dentists (mean age +/- SD, 52.2 +/- 12.1 years; women 8.0%) who participated in a nationwide cohort study from 2001 to 2006. The baseline questionnaire included a validated food-frequency questionnaire to estimate intakes of foods and nutrients. We computed the geometric means of daily intakes by the number of teeth, adjusting for age, sex, smoking, physical activity, and history of diabetes.Results:The mean intakes of some key nutrients and food groups, such as carotene, vitamins A and C, milk and dairy products, and vegetables including green-yellow vegetables, decreased with the increasing number of teeth lost (P for trend < 0.05). On the contrary, mean intakes of carbohydrate, rice, and confectioneries were increased among those with fewer teeth (P for trend < 0.05). The difference in the geometric mean (%) between totally edentulous subjects and those with >= 25 teeth, that is [(Geometric mean for >= 25 teeth) - (Geometric mean for 0 teeth)]/(Geometric mean for >= 25 teeth) x 100, was 14.3%, 8.6%, 6.1%, and -6.1% for carotene, vitamin C, vitamin A, and carbohydrate, respectively. For food groups, it was 26.3%, 11.9%, 5.6%, -9.5%, and -29.6% for milk and dairy products, green-yellow vegetables, total vegetables, rice, and confectioneries, respectively.Conclusions:Tooth loss was linked with poorer nutrition even among dentists.
