Low birth weight is an important indicator of the health of babies. A low birth weight is a leading health problem and a major reason for death in newborns. This study targeted to assess the relationship between maternal and infant factors and low birth weight in Iran through a systematic review and meta-analysis. This paper was a systematic review and meta-analysis of the relationship between maternal/ infant factors and low birth weight based on the published research papers conducted in Iran. To achieve this goal, two trained researchers independently elicited all the relevant articles by using the appropriate keywords and their combinations in SID, Madlib, Iranmedex, Irandoc, Google Scholar, Pubmed, ISI, Scopus and Magiran databases. The results of the study were combined with SPSS 20 and STATA software. In the initial stage, 25 more relevant articles out of 46 papers were selected. The gestational age with less than 37 weeks and prenatal care had the most (CI: 27- 14. 53, OR: 19.81) and the least (CI: 1.86, OR: 1.5) effect on the low birth weight in newborns, respectively. This study showed that there is a significant relationship between the low birth weight and multiple births, pre-eclampsia, maternal weight gaining during pregnancy, baby's gender, and pregnancy age. Hence, controlling the factors above in mothers during pregnancy by the health authorities could lead to the birth of infants with a healthy weight and consequently the number of infants with low birth weight will decrease.
低出生体重是婴儿健康的一项重要指标。低出生体重是一个主要的健康问题，也是新生儿死亡的一个主要原因。本研究旨在通过系统评价和荟萃分析评估伊朗母婴因素与低出生体重之间的关系。本文是基于在伊朗开展的已发表研究论文对母婴因素与低出生体重之间关系进行的系统评价和荟萃分析。为实现这一目标，两名经过培训的研究人员在SID、Madlib、Iranmedex、Irandoc、谷歌学术、PubMed、ISI、Scopus和Magiran数据库中使用适当的关键词及其组合独立检索所有相关文章。研究结果采用SPSS 20和STATA软件进行合并。在初始阶段，从46篇论文中又筛选出25篇相关文章。孕周小于37周和产前护理对新生儿低出生体重的影响最大（CI：27 - 14.53，OR：19.81）和最小（CI：1.86，OR：1.5）。本研究表明，低出生体重与多胎妊娠、子痫前期、孕期母亲体重增加、婴儿性别和孕周之间存在显著关系。因此，卫生当局在孕期控制母亲上述因素可使体重健康的婴儿出生，从而降低低出生体重婴儿的数量。
