Abstract
Objective: To investigate association between dietary habits and
asthma severity in children.
Design: Cross-sectional study.
Setting: Two teaching hospitals in Brazil.
Participants: Cases (n=268) were children (3-12yr) with
persistent asthma and age-matched controls (n=126) were those
with intermittent asthma.
Main outcome measures: Dietary habits were determined based
on food consumption in the past 12 months classified as frequent
(≥3 times per week) or infrequent (never or <3 times per
week).Nutritional status was classified into two categories
according to WHO Child Growth Standards: obese: >2Z-score of
BMI-for-age; non-obese: ≤2Z-score of BMI-for-age.
Results: After adjusting for confounding factors, maternal
smoking during pregnancy, preterm birth and obesity were
significantly associated with persistent asthma, with adjusted
ORs (95% CI) of 2.11 (1.08- 4.13), 2.61(1.07-6.35) and 2.89
(1.49-5.61), respectively. No significant association was observed
between frequency of consumption of specific foods, food groups,
or dietary pattern (pro- or contra-Mediterranean diet) and the
severity of asthma.
Conclusions: This study did not find a significant association
between dietary habits and asthma severity in children. Maternal
smoking during pregnancy, preterm birth and obesity were
independent factors associated with persistent asthma.
