Rationale: Obesity is a major health problem in Chile. Although morbid obesity is related to excess energy intake it is also associated with micronutrient deficiencies. The aims of this study were to evaluate food intake and the prevalence of micronutrient deficiencies in a group of morbidly obese women candidates for bariatric surgery.

Methods: 103 morbidly obese women prior bariatric surgery were studied. Anthropometry and determination of body fat mass by DEXA were perfomed in all subjects. Energy, macro and micronutrient intakes were determined by using a food frecuency questionnaire. Selected biochemical tests were conducted to assess nutritional status of vitamins and minerals. The blood tests included plasma iron, ferritin, transferrin, zinc, plasma copper, plasma calcium, hemoglobin, hematocrit, mean corpuscular volume (MCV) and hair zinc. In a subsample of 66 subjects, we additionally assessed folic acid, vitamin B12, vitamin D levels and parathormone (PTH).

Results: The mean estimated energy intake was 2,801 [±970] kcal/day. After adjusting for kilocalorie intake, mean carbohydrate, protein and lipid intake were of 55% [±9,1], 13,9% [±3,3] and 32,5% [±8,2] respectively. Consumption of iron and calcium were below the RDA. The prevalence of nutritional deficiencies were: 12,3% for plasma iron, 8,7% for ferritin, 14,5% for transferrin, 2,9% for plasma zinc, 13,3% for calcium, 2,3% for phosphorous, 7,7% for hemoglobin, 13,6% for hematocrit, 6,8% for MCV and 15,7% for hair zinc. In the subsample 10,6% had a vitamin B12 deficiency, 71,7% showed low levels of vitamin D and high levels of parathormone were found among 66,6%. No acid folic or cooper deficiency were detected.

Conclusion: Despite high daily energy intake and adequate macronutrient caloric distribution, there is deficient consumption of some micronutrients and high prevalence of micronutrient deficiencies in Chilean morbidly obese women seeking bariatric surgery.
