Wasting and its associated factors among under-two years children in Ethiopia: a systematic review and meta-analysis

Globally, about 45 million under-five children have suffered from wasting where Asian and African countries have the major share of these wasted children. Despite wasting is affected all types of populations, the long and short term effect is more severe and sensitive in under-two aged children. Hence, this review was intended to assess pooled prevalence and associated factors of wasting among under-two children in Ethiopia.

The search was done using electronic data bases (Hinari, PubMed, Google scholar, Scopus) and research repositories from June 19-22/2023. The review included articles published between January 2013 and December 2023.The study included Cross-sectional/case control studies which report the prevalence and associated factors of wasting in under-two aged children. The quality of included studies was assessed using the Joanna Briggs Institute (JBI) quality assessment checklists for observational studies. The presence of heterogeneity between included studies was evaluated using Cochrane Q-test and the I² statistics. Publication bias was checked through graphical and statistical test. Associated factors were estimated by random effect model using DerSimonian-Laird model weight.

The pooled prevalence of wasting among under-two children was 10.91% (95% CI: 8.97-12.85; I² = 86.36%). Absence of maternal antenatal follow up (OR; 3.23: 95%CI: 1.20-5.26), no exclusive breast feeding until six months (OR; 5.30; 95%CI: 1.17-9.43), current illness of the child (OR; 2.58: 95%CI: 1.78-3.37), large family size (OR; 12.38; 95%CI: 1.37-26.13) and low wealth status of the households (OR; 3.91; 95%CI: 1. 54-8.36) were significant factors of wasting among under-two children.

This study disclosed that the pooled prevalence of wasting among under- two children were high in Ethiopia. Absence of maternal antenatal follow up, no exclusive breast feeding, low wealth status of the households, large family size and current illness of the child were significant factors of wasting. Strictly adherence of maternal antenatal follow up, counsel the parents to feed only breast milk until six months, limit the number of family size to the level of the household income and early treatment of the sick child were recommended. Furthermore, scale up the wealth status and living standard of the family can address the agenda of reducing and eradicating all forms of malnutrition.
