Low birth weight is a significant index for survival, intrauterine growth, and mortality in infants. Thus, this study is aimed at determining the prevalence of low birth weight in Iranian infants through a systematic review and meta-analysis.
This study was performed by meta-analysis from January 2000 to December 2019. The studies relevant to the topic have been obtained through search in databases of Scopus, ScienceDirect, SID, Magiran, Barakat Knowledge Network System, Medline (PubMed), and Google Scholar. Heterogeneity of the studies has been assessed by the index, and data analysis was done using Comprehensive Meta-Analysis software.
By investigating 14 articles and 93924 infants, the total prevalence of low birth weight in infants in Iran was achieved at 8.5% (95% CI: 7.3-9.9%) according to the meta-analysis; the most prevalence of low birth weight was in infants in Hamedan at 19.1% (95% CI: 21.2-17.2%) in 2007, and the lowest prevalence of low birth weight was in infants in Tonekabon at 4.2% (95% CI: 3.4-5.2%) in 2005, and also, by increasing the sample size, the prevalence of low birth weight increases, by which the difference is statistically significant ( < 0.05).
Due to the high prevalence of low birth weight in infants in Iran, health policy-makers must take effective attempts in order to reduce it in infants.
低出生体重是婴儿生存、宫内生长及死亡率的一项重要指标。因此，本研究旨在通过系统评价和荟萃分析确定伊朗婴儿低出生体重的患病率。
本研究于2000年1月至2019年12月通过荟萃分析进行。通过检索Scopus、ScienceDirect、SID、Magiran、巴拉卡特知识网络系统、Medline（PubMed）和谷歌学术等数据库获取了与该主题相关的研究。采用 指数评估研究的异质性，并使用综合荟萃分析软件进行数据分析。
通过对14篇文章和93924名婴儿的调查，根据荟萃分析，伊朗婴儿低出生体重的总患病率为8.5%（95%置信区间：7.3 - 9.9%）；低出生体重患病率最高的是2007年哈马丹的婴儿，为19.1%（95%置信区间：21.2 - 17.2%），最低的是2005年通卡本的婴儿，为4.2%（95%置信区间：3.4 - 5.2%），而且，随着样本量的增加，低出生体重患病率上升，差异具有统计学意义（<0.05）。
由于伊朗婴儿低出生体重患病率较高，卫生政策制定者必须采取有效措施以降低婴儿的低出生体重率。
