Coastal school children who ate reddish fish (sardine, mackerel, pike) very often had a significantly lower prevalence of history of asthma than those who seldom ate reddish fish (p<0.01). There were no other significant differences for these children based on consumption of pale fish, shellfish, fish-paste, seaweed, and dried fish.
Inland school children who ate pale fish (flatfish, sea bream, turbot) and seaweed very often had significantly higher prevalence of history of asthma than those who seldom ate pale fish and seaweed (p<0.01; 0.01<p<0.05, respectively). There were no other significant differences for these children based on reddish fish, shellfish, fish-paste, and dried fish.
