Abstract：
Early acknowledgment of developmental difficulties in young children strengthens both preventive and therapeutic approaches. Despite their feasibility, early intervention services are limited in Low-and-Middle-Income (LAMI) countries compared to high income countries. The aim of this study was to examine the evidence for early childhood intervention programs for developmental difficulties in children below five years in LAMI countries through a systematic review and meta-analysis. In this background, original studies published in peer-reviewed journals from 2010 to 2019 with a focus on developmental difficulties including delays and deviances; randomized research design with a clear description of the intervention and measurable outcomes, and conducted in LAMI countries were considered for the systematic review. Electronic databases, including ProQuest, PubMed, Ovid, EBSCOhost, and Google Scholar, were searched using a combination of specific keywords. PRISMA guidelines were followed to include the studies. Each of the selected study was assessed for quality before applying appropriate statistics to synthesize the data. Fourteen publications were identified from 2697 publications for the systematic review, out of which four were found compatible for a meta-analysis. The studies reviewed were conducted in Bangladesh, India, Pakistan, Uganda, Vietnam, and Zambia. A meta-analysis of four studies provided considerable evidence for the effects of early developmental intervention. This systematic review provides an evidence for early childhood intervention programs in LAMI countries. Implications of these findings for the early childhood programs are discussed in this article.
摘要：
早期认识到幼儿的发育困难可以加强预防和治疗方法。尽管它们是可行的,与高收入国家相比,中低收入(LAMI)国家的早期干预服务有限.这项研究的目的是通过系统评价和荟萃分析，研究LAMI国家五岁以下儿童发育困难的早期儿童干预计划的证据。在这样的背景下,2010年至2019年在同行评审期刊上发表的原始研究，重点是发展困难，包括延误和偏差;随机研究设计，明确描述干预和可衡量的结果，并在LAMI国家进行了系统评价。电子数据库,包括ProQuest,PubMed,奥维德,EBSCOhost,和谷歌学者，使用特定关键字的组合进行搜索。遵循PRISMA指南以包括这些研究。在应用适当的统计数据综合数据之前，对每项选定的研究进行质量评估。从2697份出版物中确定了14份出版物用于系统审查，其中四个被发现与荟萃分析兼容。审查的研究是在孟加拉国进行的，印度,巴基斯坦,乌干达，越南,赞比亚。对四项研究的荟萃分析为早期发育干预的效果提供了大量证据。本系统综述为LAMI国家的早期儿童干预计划提供了证据。本文讨论了这些发现对幼儿计划的影响。
