摘要
目的确定因肺炎住院的 6 个月至 5 岁儿童缺乏维生素 A 的频率。方法: 由两名独立研究人员进行综合文献综述:由两名独立的研究人员进行综合文献综述,在 PubMed、LILACS、Web of Science、Scopus 和 CINAHL 等数据库以及灰色文献--OpenGrey、Proquest 和 Google Scholar 中进行检索,无语言限制和出版时间限制。在资格审查阶段,对筛选出的研究进行全文阅读,排除那些不能回答研究问题的研究。采用 Downs & Black(1998 年)核对表对研究方法的质量进行评估。结果经过各个阶段的筛选,共确定了 1642 篇文章,其中包括 10 项研究,其中 5 项为纵向研究,4 项为干预研究,1 项为横向研究。所有研究均发现肺炎住院患儿存在亚临床维生素 A 缺乏症;亚临床维生素 A 缺乏症的最高频率为 93.2%。所有评估研究均显示亚临床维生素 A 缺乏症的发生率大于 20%。结论肺炎患儿亚临床维生素 A 缺乏症的发生率很高;这些数据的关联性有待进一步探讨。因此,对这一主题进行评估的新研究至关重要。
Frequency of Vitamin a Deficiency in Children Hospitalized for Pneumonia: An Integrative Review.
Objective: To identify the frequency of vitamin A deficiency in children aged 6 months to 5 years hospitalized for pneumonia. Methods: An integrative literature review was carried out, where searches were made by two independent researchers, with no language limits or publication time in the databases PubMed, LILACS, Web of Science, Scopus and CINAHL, and in the gray literature-OpenGrey, Proquest and Google Scholar. In the eligibility phase, the screened studies were read in full and those that did not answer the research question were excluded. Methodological quality was assessed using the Downs & Black (1998) checklist. Results: 1642 articles were identified, after all stages of screening and selection, 10 studies were included, of which 5 were longitudinal, 4 were intervention and 1 transversal. All studies identified subclinical vitamin A deficiency in children hospitalized with pneumonia; the highest frequency of subclinical vitamin A deficiency was 93.2%. All studies evaluated showed frequencies of subclinical vitamin A deficiency >20%. Conclusion: There is a high frequency of subclinical vitamin A deficiency in children with pneumonia; these data need to be further explored in terms of their associations. For this reason, new studies that evaluate this topic are of fundamental importance.
