Hazard ratios for asthma, allergic rhinitis, and eczema based on multivariable Cox proportional hazard regressions*

Abbreviations: HR = hazard ratio; CI = confidence interval.

*Note: All models for 1,284 participants in this study were adjusted for 16 covariates: 6 child factors, 4 parental/demographic factors and 6 home environmental factors. Child factors included: age, sex, low birth weight (<2,500g), prematurity (child born within three weeks of due date), breastfeeding, and enrollment in childcare. Parental/demographic factors included: parental asthma and atopy, parental education level, and income adequacy. Home environmental factors included: crowding (number of people living in household) and home exposures during first year of life (use of gas to cook or heat, exposure to environmental tobacco smoke, pets, cockroaches, and mould in the home).
