Abstract
Background Currently, Pneumonia is the leading cause of morbidity and mortality among under-five children in developing countries including Ethiopia. Despite, these problems are easily preventable and treatable it contributes to more than 18% of deaths of under-five children every year in Ethiopia. Regardless of these facts, there is a paucity of information regarding the magnitude and its predictors of pneumonia in Ethiopia. Thus, assessing the pooled magnitude of pneumonia and its predictors among under-five children in Ethiopia is the main objective of this review. Methods The international databases such as MEDLINE/PubMed, EMBASE, Google Scholar, Science Direct were scientifically explored. We considered all primary studies reporting the magnitude of pneumonia among under-five children and its predictors in Ethiopia. We retrieved all necessary data by using a standardized data extraction format spreadsheet. STATA 14 statistical software was used to analyze the data and Cochrane Q test statistics and I 2 test was used to assess the heterogeneity between the studies. There was significant heterogeneity between the studies so that a random effect model was employed. Result The pooled magnitude of Pneumonia Among Under Five Children was 20.68%, (I 2 = 97.9%%; P ≤ 0.001) from 12 included studies in Ethiopia. Children who unvaccinated [OR = 2.45], food cooking in the main house [OR = 2.46], Vitamin A supplementation status [OR = 2.85], malnutrition [OR = 2.98], mixed breast feeding [OR = 2.46], child history of respiratory tract infection [OR = 4.11] were a potential determinates of pneumonia. Conclusion and Recommendations This review showed that the magnitude of pneumonia was relatively high. Hence, appropriate intervention on potential determinates such as health education on exclusive breastfeeding and nutrition, place of food cooking, increase immunization and Vitamin A supplementation and early control of respiratory tract infection was recommended to prevent those risk factors.
