Food insecurity (FI), characterized by difficulty or inability to access adequate food, has become a public health problem.
To analyze studies relating FI with nutritional status (NS) among older adults and the associated factors.
Articles published up to June 2020 were investigated in 5 databases: PubMed, Embase, Scopus, LILACS, and Web of Science. The search, selection, extraction, and quality evaluation were carried out by 2 reviewers.
The authors identified characteristics of the studies and the main data regarding the relationship of interest.
Twenty-two studies were included in the review and their characteristics are summarized and presented using narrative synthesis. In 10 studies (45.4%), a relationship was observed between FI and malnutrition; in another 6 (27.3%), a relationship was observed between FI and being overweight.
A relationship was identified between FI, especially severe forms, and malnutrition, as well as between FI, especially mild forms, and people being overweight. Thus, FI among older adults relates to a 2-fold burden of nutritional outcomes, depending on the level.

食品不安全（FI），其特征为难以或无法获得充足的食物，已成为公共卫生问题。
分析与老年人食品不安全和营养状况（NS）相关的研究，并探讨其相关因素。
在 5 个数据库（PubMed、Embase、Scopus、LILACS 和 Web of Science）中检索截至 2020 年 6 月发表的文章。由 2 位评审员进行检索、选择、提取和质量评估。
作者确定了研究的特征以及与研究目的相关的主要数据。
综述纳入了 22 项研究，其特征使用叙述性综合进行总结和呈现。在 10 项研究（45.4%）中，观察到 FI 与营养不良之间存在关联；在另外 6 项研究（27.3%）中，观察到 FI 与超重之间存在关联。
FI，尤其是严重程度的 FI，与营养不良有关，而 FI，尤其是轻度程度的 FI，与超重有关。因此，老年人中的 FI 与营养结果的双重负担有关，具体取决于严重程度。
