Abstract

Background

Anemia in older adults is a natural consequence of aging and its symptoms and side effects are mostly neglected, which leads to negative effects on the quality of life in older adults. This study is an attempt to determine the prevalence of anemia in older adults through a systematic and meta-analysis study.

Materials and Methods

This meta-analysis and systematic review was carried out in a time period from 1989 to 2022. To find articles pertinent to the topic of the study, Google Scholar, SID, MagIran, WoS, Scopus, and Embase databases were searched using keywords validated in MeSh/Emtree. Heterogeneity of studies was examined using the I2 index.

Results

The search yielded 14,999 articles and eventually, 44 articles with a total sample size of 127,978 participants met the inclusion criteria of the study. The prevalence of anemia in older adults was estimated equal to 24.6 % (CI = 95 %; 19.1–31.1 %). The highest prevalence of anemia in older adults was in Africa (45.5 %; CI = 95 %; 3.9–94.5 %) and older adults living in nursing homes (53.7 %; CI = 95 %; 27.9–77.9 %). There was no significant difference between women and men in terms of the prevalence of anemia (P > 0.05).

Conclusion

The findings indicated that the prevalence of anemia in older adults was high mostly in Africa. This finding requires more attention from experts, officials, and health policy makers.

老年人贫血的患病率:系统性荟萃分析研究
背景老年人贫血是衰老的自然结果,其症状和副作用大多被忽视,从而对老年人的生活质量造成负面影响。本研究试图通过一项系统性荟萃分析研究来确定老年人贫血的患病率。为了找到与研究主题相关的文章,我们使用在 MeSh/Emtree 中验证过的关键词搜索了 Google Scholar、SID、MagIran、WoS、Scopus 和 Embase 数据库。结果检索到 14999 篇文章,最终有 44 篇文章符合研究的纳入标准,总样本量为 127978 人。老年人贫血患病率估计为 24.6 %(CI = 95 %;19.1-31.1 %)。非洲老年人(45.5%;CI = 95%;3.9-94.5%)和住在养老院的老年人(53.7%;CI = 95%;27.9-77.9%)的贫血患病率最高。女性和男性在贫血患病率方面没有明显差异(P > 0.05)。这一发现需要专家、官员和卫生政策制定者给予更多关注。

期刊介绍: International Journal of Africa Nursing Sciences (IJANS) is an international scientific journal published by Elsevier. The broad-based journal was founded on two key tenets, i.e. to publish the most exciting research with respect to the subjects of Nursing and Midwifery in Africa, and secondly, to advance the international understanding and development of nursing and midwifery in Africa, both as a profession and as an academic discipline. The fully refereed journal provides a forum for all aspects of nursing and midwifery sciences, especially new trends and advances. The journal call for original research papers, systematic and scholarly review articles, and critical papers which will stimulate debate on research, policy, theory or philosophy of nursing as related to nursing and midwifery in Africa, technical reports, and short communications, and which will meet the journal''s high academic and ethical standards. Manuscripts of nursing practice, education, management, and research are encouraged. The journal values critical scholarly debate on issues that have strategic significance for educators, practitioners, leaders and policy-makers of nursing and midwifery in Africa. The journal publishes the highest quality scholarly contributions reflecting the diversity of nursing, and is also inviting international scholars who are engaged with nursing and midwifery in Africa to contribute to the journal. We will only publish work that demonstrates the use of rigorous methodology as well as by publishing papers that highlight the theoretical underpinnings of nursing and midwifery as it relates to the Africa context.
