Efektywność szczepienia przeciwko pneumokokom a częstość występowania infekcji dróg oddechowych oraz ostrego zapalenia ucha środkowego w populacji zdrowych dzieci w wieku 0–24 miesięcy, w zależności od sposobu ich karmienia

Publication date: November–December 2014 Source:Pediatria Polska, Volume 89, Issue 6 Author(s): Jarosław Rożnowski , Bożena Leks , Anna Rożnowska Pneumococcal vaccination, despite the effort of the medical community aimed at introducing it as obligatory, still remains in the Polish vaccination schedule as recommended, and thus have to be paid by parents. 490 healthy children (47.55% boys, 52.45% girls) were observed for the first two years of life. From those, 86 were vaccinated against pneumococcal infection. The chi-square test and odds ratio (OR) were performed for intergroup comparison of the prevalence of upper respiratory tract infections (URTIs), lower respiratory tract infections (LRTIs), and acute otitis media (AOM). Logistic regression models and the Mantel-Haenszel test for repeated tests for independence were applied for URTI, LRTI, and AOM risk assessment vs. the analysed variables. The results were presented in the raw form and adjusted for breastfeeding, OR and 95% confidence intervals. Pneumococcal vaccination statistically significantly reduced the incidence of URTIs where OR=0.53 (0.17–0.9); p=0.03 and of LRTIs where OR=0.59 (0.35–0.97); p=0.04. Moreover, hospitalization and antibiotic therapy were less frequent in vaccinated children (26.7% vs. 88.98% and 80.23% vs. 88.61% respectively). Breastfeeding longer than 6 months significantly reduced the occurrence of URTIs where OR=0.53 (0.36–0.78); p=0.001 and of AOM where OR=0.59 (0.37–0.94...
