Abstract：
UNASSIGNED: Eight databases, PubMed, CINAHL, Web of Science, Embase, PsycINFO, Cochrane Library, Popline, and Maternity and Infant Care, were searched, covering the period of January 2000 to January 2022. Studies that had examined the association between SBI and any form of child mortality were included. The findings of the included studies were summarized through fixed-effects or random-effects meta-analysis and the model was selected based on the heterogeneity index.
UNASSIGNED: A total of 51 studies were included. Of them, 19 were conducted in Ethiopia, 10 in Nigeria and 7 in Bangladesh. Significant higher likelihoods of stillbirth (odds ratio (OR) = 2.11; 95% confidence interval (CI) = 1.32-3.38), early neonatal mortality (OR = 1.58; 95% CI = 1.04-2.41), perinatal mortality (OR = 1.71; 95% CI = 1.32-2.21), neonatal mortality (OR = 1.85; 95% CI = 1.68-2.04), post-neonatal mortality (OR = 3.01; 95% CI = 1.43-6.33), infant mortality (OR = 1.92; 95% CI = 1.77-2.07), child mortality (OR = 1.67; 95% CI = 1.27-2.19) and under-five mortality (OR = 1.95; 95% CI = 1.56-2.44) were found among babies born in short birth intervals than those who born in normal intervals.
UNASSIGNED: SBI significantly increases the risk of child mortality in LMICs. Programmes to reduce pregnancies in short intervals need to be expanded and strengthened. Reproductive health interventions aimed at reducing child mortality should include proper counselling on family planning, distribution of appropriate contraceptives and increased awareness of the adverse effects of SBI on maternal and child health.

摘要：
未经评估：八个数据库，PubMed,CINAHL,WebofScience,Embase,PsycINFO,科克伦图书馆,Popline,产妇和婴儿护理，被搜查，涵盖2000年1月至2022年1月期间。包括研究SBI与任何形式的儿童死亡率之间的关系的研究。通过固定效应或随机效应荟萃分析总结纳入研究的结果，并根据异质性指数选择模型。
未经评估：共纳入51项研究。其中,在埃塞俄比亚进行了19次，尼日利亚有10个，孟加拉国有7个。死产的可能性显著较高(优势比(OR)=2.11;95%置信区间(CI)=1.32-3.38)，早期新生儿死亡率（OR=1.58；95%CI=1.04-2.41），围产期死亡率（OR=1.71；95%CI=1.32-2.21），新生儿死亡率（OR=1.85；95%CI=1.68-2.04），新生儿死亡率（OR=3.01；95%CI=1.43-6.33），婴儿死亡率（OR=1.92；95%CI=1.77-2.07），在短出生间隔出生的婴儿中发现了儿童死亡率（OR=1.67;95％CI=1.27-2.19）和5岁以下儿童死亡率（OR=1.95;95％CI=1.56-2.44）。
UNASSIGNED：SBI显著增加了低收入国家儿童死亡的风险。需要扩大和加强在短时间内减少怀孕的方案。旨在降低儿童死亡率的生殖健康干预措施应包括关于计划生育的适当咨询，分发适当的避孕药具，并提高对SBI对母婴健康的不利影响的认识。
