Abstract

Background: Malnutrition is pervasive in hospitalized patients and older adults. Although evidence shows the benefits of nutrition interventions in hospitalized patients, less is known about the role these interventions play on outcomes in patients in the community. Objective: The objective of this systematic review is to evaluate the current evidence on nutrition interventions’ impact on health and nutrition outcomes among community-dwelling adults. Methods: This systematic review was performed using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Original studies of previously published research were identified by using a predefined search strategy. Articles identified through electronic and manual searches were compared against predefined study selection criteria. Results: Twenty articles were deemed eligible for inclusion. Most of the studies examined nutrition interventions through oral nutritional supplements, dietary advice, counseling, and home visits, and were conducted in subjects who either had or were at risk of malnutrition. Nutrition interventions were found to improve anthropometrics (body weight), nutritional and functional status, energy and protein intake, and muscle strength (handgrip strength). However, their impact was inconclusive for body composition, quality of life, readmissions, complications/morbidity, and mortality, mainly due to a limited number of studies. Conclusion: Nutrition interventions were found to improve health and nutrition outcomes among community-dwelling adults. Future research is needed to examine the pervasiveness of malnutrition in the community, to evaluate the impact that nutrition interventions have on improving health outcomes in this population, and to inform the design of novel nutrition-focused intervention programs for adults living in different community settings to improve outcomes.

评估营养干预对社区居住成年人健康和营养结果的影响:一项系统综述

背景：营养不良在住院患者和老年人中普遍存在。尽管有证据表明营养干预对住院患者有好处，但人们对这些干预措施对社区患者预后的作用知之甚少。目的：本系统综述的目的是评估营养干预措施对社区成年人健康和营养结果影响的现有证据。方法：使用系统评价和荟萃分析首选报告项目（PRISMA）指南进行系统评价。先前发表的研究的原始研究是通过使用预定义的搜索策略来确定的。将通过电子和手动搜索确定的文章与预定义的研究选择标准进行比较。结果：20篇文章被认为符合入选条件。大多数研究通过口服营养补充剂、饮食建议、咨询和家访来检查营养干预措施，并在有或有营养不良风险的受试者中进行。营养干预被发现可以改善人体测量（体重）、营养和功能状态、能量和蛋白质摄入以及肌肉力量（握力）。然而，主要由于研究数量有限，它们对身体成分、生活质量、再次入院、并发症/发病率和死亡率的影响尚不确定。结论：营养干预可以改善社区成年人的健康和营养状况。未来的研究需要检查营养不良在社区中的普遍性，评估营养干预措施对改善这一人群健康状况的影响，并为为生活在不同社区环境中的成年人设计新的以营养为重点的干预计划以改善结果提供信息。
