More than three courses of
antibiotic use during infancy increased the risk of current
AR (adjusted odd ratio [aOR],
2.058; 95% confidence interval [CI]: 1.290–3.284). Having older
siblings, especially >2 (aOR, 0.526; 95% Cl: 0.303–0.913)
had a protective effect. High ERS (>median; aOR, 2.079;
95% Cl: 1.466–2.947) and PRS (>median; aOR, 1.627; 95%
Cl: 1.117–2.370) increased the risk of current AR independently.
Furthermore, children who had both high ERS and PRS showed a higher risk
of current AR (aOR, 3.176; 95% Cl: 1.787–5.645).
