The prevalence and risk factors of methicillin-resistant Staphylococcus aureus among pediatric populations: a systematic review and meta-analysis.

There is scarcity in the data about MRSA prevalence and risk factors among the pediatric population. This research explores the global prevalence and risk factors of MRSA among the pediatric population. PubMed, Scopus, Web of Sciences, and the Cochrane Central Register of Controlled Trials were systematically searched. Our primary goal was to assess the prevalence of MRSA colonization and its related risk factors in the general pediatric population. A total of 124 studies encompassing 44 million participants were included in this meta-analysis, and the overall pooled estimated global prevalence of MRSA colonization in pediatric was 5% [95% CI 4-5%]. Female sex (OR = 4.17; 95% CI, 3.31-5.27), recent surgery (OR = 3.79; 95% CI, 2.20-6.52), recent hospitalization (OR = 2.63; 95% CI, 1.78-3.86), and antibiotic use (OR = 2.42; 95% CI, 1.58-3.72) were significantly associated with higher odds of MRSA colonization.

conclusionFuture research should build on these findings by emphasizing ongoing efforts to combat MRSA in pediatric settings and implementing targeted interventions. WHAT IS KNOWN: • Methicillin-resistant Staphylococcus aureus (MRSA) is considered a threat to public health. It is noteworthy to mention that the prevalence of MRSA strains has not been adequately quantified in many countries, especially in the pediatric population. The pediatric population is a pivotal source of MRSA and may play a central role in its distribution in both community and healthcare settings. A notable study underscores the gravity of the situation, estimating a tenfold increase in the incidence of MRSA infection among children in the USA between 1999 and 2008. WHAT IS NEW: • Here we present the first global systematic review and meta-analysis to investigate the prevalence and risk factors of MRSA among the pediatric population. A total of 124 studies encompassing 44 million participants were included in this analysis. The overall pooled estimated global prevalence of MRSA colonization in the pediatric population was 5% [95% CI 4-5%]. The prevalence was the highest in Asia and lowest in Europe. Female sex, recent surgery, recent hospitalization, and antibiotic use were significantly associated with higher odds of MRSA colonization.
