Avaliação da ingestão de micronutrientes e da qualidade nutricional da dieta de mulheres candidatas à cirurgia bariátrica em hospital municipal de Várzea Grande – MT

Abstract

Nutritional deficiencies are common in obese patients who are candidates for bariatric surgery and the combination of deficiency in the preoperative period and malabsorption caused by the surgical procedure can lead the patient to significant nutritional deficits during the postoperative period, with emphasis on the lack of micronutrients. The aim of the study was to evaluate the intake and nutritional quality of the diet in relation to vitamin B12, vitamin D, calcium and iron in women in the preoperative period of bariatric surgery. The patients were submitted to a Food Frequency Questionnaire, andthe intake of micronutrients and the nutritional quality of the diet were assessed using theIndex of Nutritional Quality (INQ). The median of vitamin B12 intake was 1.88 times greater than the RDA (2.4µg/day), vitamin D reached 91.6% and 45.8% of AI (5 and 10µg/day), calcium corresponded to 62.2% and 51.85% of the AI (1,000 and 1,200 mg/day) and those of iron reached 62% and 139.6% of the RDA (18 mg and 8 mg) for theage groups from 20 to 50 years and 51 to 60 years, respectively. Sixty-one percent of thediets had an INQ for calcium <0.5 and 36.5% had an INQ for iron and vitamin D <0.5. Therefore, calcium and iron intakes were less adequate in the studied group. Calcium had the worst INQ, followed by vitamin D and iron. These results suggest the susceptibility of lack of these nutrients, especially in the postoperative period.
