Clinical data and nasal aspirates were collected from March to July 2018.Results: A total of 1876 patients were enrolled. Prevalence of S. aureus and MRSA colonization were 33% (95% CI 30.9– 35.1) and 1.44% (95% CI 0.9– 2), respectively. Thirty-three percent of the children (633/1876) presented chronic conditions, mainly atopic dermatitis, asthma and/or allergy (524/633). Factors associated with S. aureus colonization were age ≥ 5 years (OR 1.10, 95% CI 1.07– 1.12), male sex (OR 1.43, 95% CI 1.17– 1.76), urban setting (OR 1.46, 95% CI 1.08– 1.97) and the presence of asthma, atopic dermatitis or allergies (OR 1.25; 95% CI: 1.093– 1.43). Rural residence was the only factor associated with MRSA colonization (OR 3.62, 95% CI 1.57– 8.36). MRSA was more frequently resistant than methicillin-susceptible S. aureus to ciprofloxacin [41.2% vs 2.6%; p< 0.0001], clindamycin [26% vs 16.9%; p=0.39], and mupirocin [14.3% vs 6.7%; p=0.18]. None of the MRSA strains was resistant to tetracycline, fosfomycin, vancomycin or daptomycin.Conclusions: The main risk factors for S. aureus colonization in Spanish children are being above five years of age, male gender, atopic dermatitis, asthma or allergy, and residence in urban areas. MRSA colonization is low, but higher than in other European countries and is associated with rural settings.Keywords: S. aureus, MRSA, child, colonization
