Regional and sub-regional estimates of low birth weight and its determinants in 44 low- and middle-income countries: evidence from demographic and health survey data.
Article in BMC pediatrics, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundLow birth weight continues to be a significant cause of perinatal morbidity and mortality, contributing to 80% of neonatal deaths in low and middle-income countries. To the authors' knowledge, no prior study has estimated the regional and sub-regional prevalence of low birth weight and its determinants in these settings. Therefore, this study aimed to examine the pooled and regional estimates of low birth weight in low and middle-income countries.
methodsWe used a weighted sample of 343,898 birth records, taken from the pooled demographic and health surveys conducted from 2015 to 2022 in 44 low and middle-income countries. Overall and sub-regional trends in low birth weight estimates were presented using a line graph. A multilevel mixed-effect analysis was done to identify determinants of low birth weight. Model comparison was performed using deviance and log-likelihood values, and statistical significance was determined at a P-value of less than 0.05.
resultsThe overall prevalence of low birth weight births was 13.7% [95% CI: 13.5%-13.8%], showing significant variations among countries and regions. Asia region had the highest prevalence at 16%, followed by Latin America, the Caribbean, and Europe at 11.5%, and Africa at 9.5%. Our study also indicated a decline in low birth weight from 11.4% to 9.5% over eight-year periods, with no consistent trend observed. Furthermore, factors such as health insurance, household wealth, maternal age, access to healthcare facilities, maternal education, neonate's sex, prenatal care, and antenatal iron supplementation were found to be statistically associated with low birth weight.
conclusionOur findings highlight the significant burden of low birth weight births, with notable variations in rates among countries and regions. The study also reveals a slight decline in low birth weight over time, although no consistent trend was observed. Importantly, maternal and household factors play significant roles in influencing low birth weight. Thus, addressing these factors through targeted interventions and policies could help reduce the incidence of low birth weight births in LMICs.
