Objectives: To describe the characteristics of infant asthma and to identify factors for the persistence of infant asthma into school age. Methods:This was a retrospective, descriptive, analytical study that included 115 children diagnosed with infant asthma. We identified factors predictive of asthma persistence at school age by univariate and multivariate statistical analysis using logistic regression. Results: The diagnosis of asthma was made on average at 18.83 ± 8.3 months of age. Two groups were identified: transient wheezers S- (n=34/29.6%) and persistent wheezers S+ (n=81/70.4%)....
