Sommaire de l'article

Our aim was to evaluate the role of maternal nutritional habits during the period of gestation and of children subsequent diet in the etiology of pediatric brain tumors. All cases of incident nervous system tumors under age 18, diagnosed between 1984 and 1993 (n = 300) in Israel were identified.

Two matched population controls per case were selected (n = 574). Personal interviews, using a semi-quantified three-step food frequency questionnaire, were performed.

Univariate analysis showed that increased child consumption of vegetable fat [p trend 0.01; 95% confidence interval (CI) 1.1-3.2], carbohydrates (p trend 0.05; CI 1.0-5.9), and vitamin E (p trend 0.05; CI 1.0-3.3), were significantly associated with brain tumor risk. No associations were found with nitrate, nitrite or vitamin C. A significant positive association with potassium consumption (p trend 0.01; CI 1.1-3.7) was noted during gestation. Results of multivariate analysis showed that the only persisting associations were with vegetable fat (OR = 1.36; CI 1.06-1.73) in the child diet and potassium intake during gestation (OR = 1.44; CI 1.04-1.99).

In conclusion, nutritional associations with pediatric brain tumor etiology, remain unsubstantiated.
