Results Rapid BMIz gain was found in 45.8% infants and excessive BMI gain in 24.4%. Boys showed a significantly higher BMIz gain than girls. Girls with rapid BMIz gain showed a significantly higher prevalence of hospitalization for wheezing (8.8% vs 6.4%; aOR: 1.4, 95%CI: 1.1 to 1.8), severe wheezing (18.1% vs 15.0%; aOR: 1.3, 95%CI: 1.0 to 1.5) and medical diagnosis of asthma (7.5% vs 5.7%; aOR: 1.3, 95%CI: 1.0 to 1.7). Girls with excessive BMIz gain also had a significantly higher prevalence of hospitalization for wheezing (9.8% vs 6.7%; aOR: 1.5, 95%CI: 1.1 to 2.0) and severe wheezing (18.9% vs 15.5%; aOR: 1.3, 95%CI: 1.0 to 1.6). No significant association was found among boys. Breastfeeding was significantly less frequent among infants with rapid and excessive BMIz gain.
