Material And Methods: Using the data from the Estudio Internacional de Sibilancias en Lactantes (EISL) in the region of Pamplona, associations between food and factors were analysed. A score of Mediterranean diet was established and the scores according to the factors were studied.

Results: Significant differences in the Mediterranean diet score by level of education (p=<0,001), occupation (p=0,015) and age (p=<0,001) were found.

Conclusion: Women with better education, better occupation and older show a greater affinity to the Mediterranean diet during pregnancy.
