Table 1
Percentages and (numbers) of 2 year old children who consumed different foods on 6 or 7 days/week, crude prevalences of asthma and wheeze at age 3 in children who, at age 2, used different foods on a daily basis (“daily use”) compared with children with lower consumption frequencies (others) and adjusted odds ratios† for the relationship between daily consumption‡ of different foods at age 2 and prevalence of asthma and wheeze at age 3, stratified for parental allergy
| Foods | Percentage (n) daily users | “Ever asthma” | Recent asthma | Recent wheeze | ||||||
|---|---|---|---|---|---|---|---|---|---|---|
| Crude % prevalence | Adjusted OR (95% CI) | Crude % prevalence | Adjusted OR (95% CI) | Crude % prevalence | Adjusted OR (95% CI) | |||||
| “Daily use” | Others | “Daily use” | Others | “Daily use” | Others | |||||
| *p<0.05, §p<0.10 for difference in asthma or wheeze prevalence between daily users and less frequent consumers. | ||||||||||
| †Adjusted for consumption frequencies of foods shown in the table, consumption frequency of semi-skimmed milk, consumption frequency of margarine, sex, birth weight, presence of older sibling(s), maternal education, having been breast fed for ⩾8 weeks, and parental smoking in the home. | ||||||||||
| ‡For full cream milk and butter odds ratios are shown for daily consumption (on 6–7 days/week) compared with 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 versus all others. | ||||||||||
