    Abstract:
    OBJECTIVE: To evaluate folic acid deficiency and other risk factors and their relationship with the occurrence of neural tube defects (NTD), in the rural population of northern Mexico (Chihuahua, Durango and Zacatecas). MATERIAL AND METHODS: A multicentric case-control study was performed. Cases were both live and stillborn with NTD, and controls were healthy newborns without congenital malformations. Exposure to known risk factors was determined, establishing its association with NTD using multiple logistic regression analysis. RESULTS: Risk factors associated to NTD were: folic acid deficiency (OR 11.1; CI 95% 1.2-106.2, p = 0.04); the antecedents of previous NTD pregnancies (OR 3.3; CI 95% 1.1-18.8, p = 0.05) and stillbirths (OR 7.1; CI 95% 1.1-46.3, p = 0.04). CONCLUSIONS: Folic acid deficiency is one of the major risk factors associated to NTD among the rural population of northern Medico. Further investigations are necessary to determine the role of involved risk factors and implement adequate preventive measures.
