Abstract
Background: Exclusive
breastfeeding up to 6 months of age is the global recommendation of the World
Health Organization because of its established benefits. Previous studies show
that exclusive breastfeeding can protect infants during infancy but effects of
breastfeeding beyond infancy are inconclusive. This study aims to identify if
exclusive breastfeeding up to 6 months of age is protective for pneumonia up to
5 years of age.
Methods: Systematic literature
search was conducted on the following electronic databases: Pubmed, MEDLINE,
EMBASE, CINAHL, SciHub, Herdin, Google Scholar, the Cochrane Central Register
of Controlled Trials and the Cochrane Database of Systematic Reviews to
identify all relevant studies assessing the effect of exclusive breastfeeding
on development of pneumonia in children from birth to 5 years of age. Fixed
effects meta-analysis was performed to generate pooled effect estimates (odds
ratio) on the probability of developing pneumonia up to 5 years of age in
exclusively breastfed compared to non-exclusively breastfed infants.
Results: Five studies were
included in the analysis. Exclusive breastfeeding from birth to 6 months has a
protective effect against pneumonia in children up to 5 years of age. The
probability of developing pneumonia in children until 5 years of age was
significantly lower in those who were exclusively breastfed compared to those
who were not exclusively breastfed (OR=0.86; 95%CI=0.77-0.95, pvalue=0.003) by
23%. Systematic review showed benefit of exclusive breastfeeding and continued
breastfeeding for longer protection against developing pneumonia.
Conclusion: Exclusive
breastfeeding from birth to 6 months is associated with statistically
significant reduction in the incidence of pneumonia up to 5 years of age.
Results highlighted the importance of exclusive breastfeeding up to 6 months of
age as an intervention in reducing pneumonia morbidity up to 5 years of age,
thereby supporting the global recommendation of breastfeeding.
