Relationship between consumption frequency† of full cream milk, milk products, butter and brown bread and prevalences of asthma and wheeze (n=2978)
Regression models | “Ever asthma” (n=195) | Recent asthma (n=145) | Recent wheeze (n=442) |
---|---|---|---|
Values are presented as odds ratios (with 95% confidence intervals). | |||
*p<0.05; **p<0.01. | |||
†Odds ratios are shown for daily consumption and regular consumption v consumption less than once a week; for milk products and brown bread the prevalence of consumption less than once a week is less than 5% and therefore odds ratios are shown for daily consumption v all others. | |||
