Abstract

Objectives

Early detection and management of malnutrition is essential for the general health and well-being of the elderly. Various studies have reported different types of malnutrition prevalence in the elderly. the present study was aimed to determine the prevalence of malnutrition in the world’ elderly through conducting a systematic review study and meta-analysis.

Study Design: systematic review and meta-analysis.

Methods

In this review study, data was extracted by searching in national and international databases of SID, MagIran, Google scholar, ScienceDirect, Scopus, PubMed and Web of Science (WoS) without time limit until August 25, 2023. For analysis, Begg and Mazumdar test at a significance level of 0.1 and the corresponding Funnel plot were used. Data analysis was performed with Comprehensive Meta-Analysis software (Version 2).

Results

In the review of 98 studies with a total sample size of 79976, the prevalence of malnutrition in the world's elderly was obtained as 18.6 % (95 % confidence interval: 16.4-21.1 %), so that the highest prevalence of malnutrition was in the elderly of Africa with 35.7 %, followed by the America with 20.3 %. According to the subgroup analysis regarding the indicators of malnutrition in the elderly, the highest prevalence of malnutrition in the elderly was obtained as 39.9 % according the NRS-2002 index.

Conclusion

Therefore, in addition to raising awareness among families about malnutrition in the elderly and its negative effects on the quality of life of the elderly, it is necessary to take the necessary measures to provide more care for the elderly and also to pay serious attention to the importance of nutrition during old age.

老年人营养不良的全球患病率：一项全面的系统回顾和荟萃分析。

目标：营养不良的早期发现和管理对老年人的总体健康和福祉至关重要。各种研究报告了老年人中不同类型的营养不良患病率。本研究旨在通过系统回顾研究和荟萃分析来确定世界老年人营养不良的患病率。研究设计：系统评价和荟萃分析。方法：在本综述性研究中，通过SID、MagIran、谷歌scholar、ScienceDirect、Scopus、PubMed和Web of Science （WoS）等国内外数据库的检索提取数据，无时间限制，检索截止日期为2023年8月25日。分析采用Begg和Mazumdar检验，显著性水平为0.1，并采用相应的漏斗图。结果：共纳入98项研究，总样本量为79976份，全球老年人营养不良患病率为18.6%(95%可信区间为16.4 ~ 21.1%)，其中非洲老年人营养不良患病率最高，为35.7%，其次是美洲，为20.3%。对老年人营养不良指标进行亚组分析，根据NRS-2002指数，老年人营养不良患病率最高，为39.9%。结论：因此，除了提高家庭对老年人营养不良及其对老年人生活质量的负面影响的认识外，还需要采取必要的措施，为老年人提供更多的照顾，并认真重视老年营养的重要性。
