  • P values, RR, and 95% confidence interval were determined by logistic regression adjusted with age. Analyses have been done separately for each risk factor.

  • * The following factors were insignificant in the prediction of asthma: positive viral identification on entry, family history of atopy or asthma, male sex, passive smoking during pregnancy or early childhood, urban living area during infancy, 2 or more siblings, and elevated serum IgE on entry.
