Background: Diet during pregnancy and childhood has been suggested to play an important role in children’s asthma risk. We assessed whether the adherence to a Mediterranean dietary pattern, for children in the last 12 months and their mothers during pregnancy, was associated with both childhood asthma and allergic rhinitis. Methods: A cross‐sectional study was conducted in 2004 using a random sample of 1476 children (6‐ to 7‐year old) from the Mexicali region, Mexico. Dietary data of children’s intake in the last 12 months and their mothers’ intake during pregnancy was collected, through a parental food frequency questionnaire. A Mediterranean diet score was computed [Trichopoulou et al., N Engl J Med 348 (2003), 2599]. Data on seven asthma and rhinitis‐related outcomes were obtained from the International Study of Asthma and Allergies in Childhood questionnaire. Results: Adherence to a Mediterranean dietary pattern was inversely associated with asthma ever (OR = 0.60, 95% CI = 0.40–0.91), wheezing ever (0.64, 0.47–0.87), rhinitis ever (0.41, 0.22–0.77), sneezing ever (0.79, 0.59–1.07), current sneezing (0.71, 0.52–0.96) and current itchy‐watery eyes (0.63, 0.42–0.95). No associations were found using the mothers’ pregnancy diet score, except for current sneezing (0.71, 0.53–0.97). Conclusions: Our findings suggest a protective effect of following a healthy dietary pattern on asthma and allergic rhinitis in Mexican children.
