Total fish intake/week

Ever eat fresh fish, fresh oily fish, or fresh non-oily fish

There were no significant differences in total fish intake between children with normal airways (1.2 servings, 95% CI 1.0-1.3), airway hyperresponsiveness (1.2 servings, 95% CI 0.9-1.5), wheeze (1.2 servings, 95% CI 0.8-1.5) and current asthma (1.0 servings, 95% CI 0.8-1.2).

Significantly fewer children with asthma ever ate oil fish compared to children with normal airways (p<0.05); however, there was no significant difference between those with current asthma and normal children who ate exclusively oily fish.

After adjusting for atopy, parental asthma, parental smoking, ethnicity, country of birth, early respiratory illness, and sex:

Children who ate oily fish had a significantly lower OR of current asthma when compared to children who did not eat oily fish (OR=0.26, 95% CI 0.09-0.72); and

There were no other significant associations found between type of fish (fresh fish, oily fish, non-oily fish) and airway hyperresponsiveness, wheeze, or current asthma.


Percentage of total energy consumed as PUFA: 3%-12%

Range of fish intake not reported

There were no significant associations found between total PUFA intake (% of total fat) for current wheezing, severe wheezing, allergic rhinoconjunctivitis, and atopic eczema.

There was a significant inverse association found between all fish (fresh and frozen) consumption and asthma, allergic rhinoconjunctivitis, and atopic eczema, for the 13- to 14-year-old age group; the same inverse association remained for the 6- to 7-year-old age group, but the association was weaker.
