Background: Stunting is an important predictor of growth and development of children under 5 years of age, and it remains the significant problem in LMIC. However, LBW emerges as risk factor, but its association with LMIC needs attention. Objective: This systematic review and meta-analysis aimed to investigate the association of low birth weight with the risk of childhood stunting among the age group of 0–5 years in LMICs. Methods: PubMed, Google Scholar, MEDLINE, Embase, and Web of Science databases were searched from January 1, 2010 untill December 20, 2021. Cross-sectional, cohort, and case-control study designs were included in the meta-analyses. The pooled odds ratio with a 95% confidence interval was reported considering the random-effects and the quality-effects models. The subgroup analysis and meta-regression were conducted for study design, geographical location, and sample size. Results: Low birth weight was associated with >2-fold increased risk of childhood stunting (pooled OR: 2.32; 95% CI, 2.05–2.62). Asian studies have shown relatively higher risk than African studies in stratified analyses. The cohort studies predicted a higher risk of childhood stunting, followed by case-control and cross-sectional study designs, and the sample size stratification showed that studies with sample size <1,000 predicted much higher risk than relatively to the studies with sample size >1,000. The meta-regression was performed in all three subgroups, but none of the models appeared significant. Conclusion: This meta-analysis confirmed the association of low birth weight with the higher risk of childhood stunting among the 0–5 years' age group and suggests a moderately higher risk in Asia as compared to Africa.
