Introduction: Squamous Intraepithelial Lesions (SIL) is a state of transition to cervical cancer (CC), and micronutrient defi ciencies can speed up this process. Therefore, determining the existence of this defi cit and know what factors are associated would allow for possible prevention in this population at risk. Objective: To determine the presence of some micronutrient defi ciencies involved in the anti-carcinogenic process, also associate this defi cit with habits and demographic factors in patients with SIL in Ciudad Juarez, Chihuahua, Mexico. Methods: An analytic cross-sectional study, 102 patients were selected with SIL. A dietary survey (24-hour recall) was performed to estimate the intake of micronutrients. The defi ciency was determined when the consumption was less than 75% of the Recommended Dietary Allowances (RDA) or suggested in Mexico. Some habits and demographic factors were obtained by interview with the patient. A logistic regression was performed to associate the presence of defi ciencies with factors that affecting the intake or increase the requirement of micronutrients. Results: Retinol, folic acid, zinc, vitamins C and E, considered micronutrients in the anti-carcinogenic process CC, were less than 75% of the RDA. Women with overweight, obesity and housewives, were signifi cantly associated with micronutrient defi ciencies. Conclusion: Overweight, obesity and occupation have been associated to present micronutrient defi ciencies in this study. These variables converge on a possible food insecurity, which could be associated with increased incidence of CC in Mexico.
