OR, odds ratio; CI, confidence interval. The reference category is based on the lowest category of intake. Diet was assessed in 1993 and the frequency of asthma attacks in 2003. Among the 992 current asthmatics, 206 had frequent asthma attacks and 786 had no frequent asthma attacks.
Based on each intake category and modelling these as continuous variables in a logistic regression.
Logistic regressions adjusted for age, caloric intake and body mass index.
Logistic regressions adjusted for age, caloric intake, body mass index, tobacco consumption, physical activity, menopausal status, education and multivitamin supplements use.
