Abstract
- PURPOSE
To investigate the impact of dietary pattern on the risk of asthma development, we undertook a nation-wide study with ISSAC written questionnaire.
METHODS
We analyzed the relations between the previous 12-month dietary patterns (16 food groups) and asthma symptom prevalence, using the ISSAC written questionnaire and a domestically developed dietary questionnaire in 24,260 elementary school children.
RESULTS
Odds ratios (OR) were significantly decreased by increased food intake of natural seafood (OR:0.88, P=0.0126, 95% CI:0.795-0.973), fruit (OR:0.785, P<0.0001, 95% CI:0.715-0.861), vegetables (OR:0.825, P<0.0001, 95% CI:0.764-0.891), and cow's milk (OR:0.9, P=0.0451, 95% CI:0.811-0.998). Compared to children that seldom consumed natural seafood, ORs of symptom development were lower in children that ate natural seafood 1-2 times per week (OR:0.863, P=0.028, 95% CI:0.761-0.978) and almost everyday (OR:0.802, P=0.0755, 95% CI:0.630-1.023), respectively. For green vegetables, ORs were significantly lower than in children who also ate gree vegetables 1-2 times per week (OR:0.753, P=0.0416, 95% CI:0.595-0.950) and almost everyday (OR:0.674, P=0.0179, 95% CI:0.408-0.752), respectively. Fruits showed the same pattern as green vegetables.
CONCLUSION
Taken together, our study shows that the increased intake of natural seafood, fruit, and vegetables is significantly related to reduced asthma symptom prevalence in Korean children.
