Social ties are associated with the mortality and morbidity of aging populations; however, the role of social ties in healthy eating practices or gender differences in this link is less understood.
The objective of this study was to examine the longitudinal evidence for the impact of changes in social ties on fruit and vegetable (FV) intakes among aging adults, with attention to gender differences.
Medline, Embase, Scopus, CINAHL, and ProQuest databases were searched until December 2022.
Longitudinal studies evaluating changes in living arrangement, marital status, social network, or social participation and changes in FV intake among middle- and older-age adults were included. Data from the included studies were extracted using a standardized template and analyzed using a narrative approach.
A total of 4956 titles were eligible after deduplication, and 75 full texts were screened. Seven studies met the inclusion criteria, and all examined marital transitions only. Five marital transitions were assessed: staying married, becoming widowed, becoming divorced, remaining unmarried, and becoming married. Both the quantity and variety of fruit and/or vegetables eaten were studied. Three of the included studies had only male or only female populations. The studies found that marital dissolution (divorce or widowhood), and remaining unmarried, were associated with reduced FV intakes in older women or men, compared with staying married. The associations were stronger in men than in women. Two studies showed that becoming married was associated with increased vegetable intakes, but 3 reported null results. The included studies were of medium quality.
There is a paucity of longitudinal research on whether changes in social ties are associated with changes in FV intakes among aging adults. This review showed that specific marital transitions may influence healthy eating habits, especially in older men. No evidence exists on whether changes in other social ties might alter healthy eating.

社会关系与老年人群的死亡率和发病率相关；然而，社会关系在健康饮食行为中的作用或此关联中的性别差异尚鲜为人知。
本研究的目的是检验社会关系变化对老年人水果和蔬菜（FV）摄入量影响的纵向证据，并关注性别差异。
检索了Medline、Embase、Scopus、CINAHL和ProQuest数据库，直至2022年12月。
纳入评估中老年人生活安排、婚姻状况、社交网络或社会参与的变化以及FV摄入量变化的纵向研究。使用标准化模板提取纳入研究的数据，并采用叙述性方法进行分析。
去重后共有4956个标题符合条件，筛选了75篇全文。七项研究符合纳入标准，且均仅考察了婚姻转变情况。评估了五种婚姻转变：保持已婚、丧偶、离婚、未婚和结婚。研究了水果和/或蔬菜的食用量和种类。纳入的三项研究仅包含男性或女性人群。研究发现，与保持婚姻相比，婚姻解体（离婚或丧偶）以及未婚与老年女性或男性的FV摄入量减少有关。男性的关联比女性更强。两项研究表明结婚与蔬菜摄入量增加有关，但三项研究报告无显著结果。纳入研究质量中等。
关于社会关系变化是否与老年人FV摄入量变化相关的纵向研究较少。本综述表明，特定的婚姻转变可能会影响健康饮食习惯，尤其是在老年男性中。尚无证据表明其他社会关系的变化是否会改变健康饮食。
