Several studies have examined the impact of tooth loss on nutrient intake, yielding mixed results.
This cross-sectional study aimed to investigate the association among the number of teeth present, nutrient intake and food group consumption in Japanese adults with no history of the four major diseases (diabetes, cancer, heart disease and stroke).
Data were obtained from the baseline survey of the Japan Multi-Institutional Collaborative Cohort study conducted in the Shizuoka and Daiko areas. Participants completed a self-administered questionnaire on their number of teeth, medical history (diabetes, cancer, heart disease and stroke), education level, employment status and lifestyle factors, such as diet, smoking history and exercise habits. The number of teeth was classified into four groups: 0 teeth, 1-19 teeth, 20-27 teeth and 28-32 teeth.
A total of 8912 individuals included in the analysis had a mean age ± SD of 51.7 ± 9.5 years, with women accounting for 53.6% of the total. In adult men, the number of teeth was negatively associated with the intake of vitamin D, n-3 highly unsaturated fatty acid intake and seafood, while in women, bread consumption was positively associated with the number of teeth.
These findings suggest that the number of teeth is independently associated with poor nutritional status in Japanese adults with no history of the four major diseases.
多项研究探讨了牙齿缺失对营养摄入的影响，结果不一。
这项横断面研究旨在调查无四大疾病（糖尿病、癌症、心脏病和中风）病史的日本成年人中现存牙齿数量、营养摄入和食物组消费之间的关联。
数据来自静冈和大湖地区进行的日本多机构合作队列研究的基线调查。参与者完成了一份关于牙齿数量、病史（糖尿病、癌症、心脏病和中风）、教育水平、就业状况和生活方式因素（如饮食、吸烟史和运动习惯）的自填问卷。牙齿数量分为四组：0颗牙、1 - 19颗牙、20 - 27颗牙和28 - 32颗牙。
纳入分析的8912名个体的平均年龄±标准差为51.7±9.5岁，女性占总数的53.6%。在成年男性中，牙齿数量与维生素D摄入量、n - 3高度不饱和脂肪酸摄入量和海鲜摄入量呈负相关，而在女性中，面包消费量与牙齿数量呈正相关。
这些发现表明，在无四大疾病病史的日本成年人中，牙齿数量与营养状况不佳独立相关。
