INTRODUCTION/OBJECTIVE: A systematic review was conducted to explore whether tooth loss affects dietary intake and nutritional status among adults.
Longitudinal studies of population-based or clinical samples of adults exploring the effect of tooth loss on food/dietary/nutrient intake and/or nutritional status were included for consideration. The risk of bias was assessed using the Newcastle-Ottawa Scale for cohort studies.
A search strategy was designed to find published studies on MEDLINE, EMBASE and LILACS up to March 2017.
Eight longitudinal studies in 4 countries (United States, Japan, Australia and Brazil) were included. Five of the six studies investigating the association between tooth loss and dietary intake showed significant results. The only consistent association, as reported in 2 studies, was for greater (self-reported) tooth loss and smaller reductions in dietary cholesterol. Three of the 4 studies investigating the association between tooth loss and nutritional status showed significant results. However, most results were contradicting. The quality of the evidence was weak.
There is at present no strong evidence on the effect of tooth loss on diet and nutrition, with inconsistent results among the few studies identified. Additional high-quality longitudinal studies should address the limitations of previous studies identified in this review.
介绍/目的：系统评价旨在探讨牙齿缺失是否会影响成年人的饮食摄入和营养状况。
纳入了关于成人牙齿缺失对食物/饮食/营养素摄入和/或营养状况影响的基于人群或临床样本的前瞻性研究。使用纽卡斯尔-渥太华量表评估队列研究的偏倚风险。
设计了搜索策略，以查找截至 2017 年 3 月在 MEDLINE、EMBASE 和 LILACS 上发表的研究。
纳入了来自 4 个国家（美国、日本、澳大利亚和巴西）的 8 项前瞻性研究。在 6 项研究中，有 5 项研究表明牙齿缺失与饮食摄入之间存在显著关联。只有两项研究报告了一致的关联，即牙齿缺失越多，膳食胆固醇的摄入量减少越多。在 4 项研究中，有 3 项研究表明牙齿缺失与营养状况之间存在显著关联。然而，大多数结果相互矛盾。证据质量较弱。
目前尚无确凿证据表明牙齿缺失对饮食和营养有影响，为数不多的研究结果不一致。应开展更多高质量的前瞻性研究，以解决本综述中确定的先前研究的局限性。
