Briefly, parents from 22 centres (14 Latin American and 8 European) answered a validated questionnaire (Int Arch Allergy Immunol 2007;144:44-50) on wheezing and risk factors during the 1st year of life of their children. They were grouped as BP+WZ+; BP+WZ-; BP-WZ+; and BP-WZ- (comparator). Associations (aOR 95%CI) were tested using multivariate random-effects logit models, with centre as the panel variable.Results: Infants grouped: BP+WZ+ 3415; BP+WZ- 913; BP-WZ+ 11688; BP-WZ-18659. Among WZ+, BP was less likely to occur when correctly vaccinated (aOR: 0.68; 0.54-0.85 vs 0.90; 0.77-1.04). Among BP+, risk factors were different depending on WZ (table)View this table:Conclusions: In infants who had BN during the 1st year of life, there are some risk factors which are different for WZ+ and WZ-.
