目的通过一项具有全国代表性的研究，探讨中国老年人天然牙数量与总体膳食多样性和营养状况的关系。材料与方法对来自中国纵向健康长寿研究的65岁及以上社区居民进行横断面分析。根据受试者自报的天然牙数分为>= 20、10-19、1-9、无牙。采用简化的食物频率问卷对10个食物组的摄入频率进行评估，构建膳食多样性评分（DDS）。使用老年营养风险指数来衡量一个亚组参与者的营养不良状况（即正常、轻度营养不良和中度至重度营养不良）。使用线性和多项逻辑回归模型来检验相应的关联。结果54,796名研究对象中，平均（SD）年龄为87.86（11.45）岁，82.7%的人牙列不良(
Aim To investigate the association of the number of natural teeth with overall dietary diversity and nutritional status in a nationally representative study among older adults in China. Materials and Methods A cross-sectional analysis was conducted among community-dwelling adults aged 65 years or older from the Chinese Longitudinal Healthy Longevity Study. According to the self-reported number of natural teeth, participants were categorized into >= 20, 10-19, 1-9 natural teeth, and edentulous. Dietary diversity score (DDS) was constructed based on intake frequencies of 10 food groups assessed by a simplified food frequency questionnaire. The geriatric nutritional risk index was used to measure the malnutrition status (i.e., normal, mild malnutrition, and moderate-to-severe malnutrition) among a subgroup of participants. Linear and multinomial logistic regression models were used to examine the corresponding associations. Results Among 54,796 study participants, the mean (SD) age was 87.86 (11.45) years, 82.7% had poor dentition (
