BackgroundWheezing is a very common respiratory symptom in infants. The prevalence of wheezing in infants, conducted in developed countries shows prevalence rates ranging between 20% and 30%. However, we do not know the risk factors in our population of wheezing infants.MethodsA standardised written questionnaire (WQ-P1-EISL) in infants between 12 and 18 months of age residing in the city of Cordoba was used; population/sample included 1031 infants. Recurrent wheezing (RW) was defined as three or more episodes of wheezing reported by the parents during the first 12 months of life. Data obtained were coded in Epi-Info™ (version 7) and statistically analysed with SPSS (version 17.5) software in Spanish. Parametric tests (one-way ANOVA) were performed for identifying significantly associated variables.ResultsThe prevalence of wheezing infants was 39.7%; recurrent wheezing 33%; and severe wheezing 14.7%; 13.7% had pneumonia before the first year and of these 6.3% were hospitalised, multiple variables as risk factors for wheezing were found such as: >6 high airway infections and bronchiolitis in the first three months of life, smokers who smoke in the home among other risk factors and protective factors in those who have an elevated socioeconomic status.ConclusionIt is known that persistent respiratory problems in children due to low socioeconomic status is a risk factor for wheezing, pneumonia and could be a determining factor in the prevalence and severity of RW in infants. Research suggests that there are areas for improvement in the implementation of new educational strategies.
