title: Diet micronutrient adequacy of women after 1 year of gastric bypass.
abstract: BACKGROUND
  The more effective treatment for severe obesity is bariatric surgery. Gastric bypass is a surgical technique used worldwide; however, as well as other techniques; it has postoperative risks, including nutrient deficiency.
  
  
  OBJECTIVE
  To determine the amounts of dietary iron, calcium, vitamin D and vitamin B12 ingested by patients of a public hospital one year after gastric bypass, and compare with the recommendations of the Recommended Dietary Allowances.
  
  
  METHODS
  This was a transverse descriptive study and the sample consisted of 36 women, with at least one year of gastric bypass. Data collected included sociodemographic, anthropometric and diet variables. Dietetic information was collected through a validated food frequency questionnaire. Ingestion of iron, calcium, vitamin D and vitamin B12 was evaluated in comparison with the Recommended Dietary Allowances, as well as correlation of micronutrient ingestion with time of surgery.
  
  
  RESULTS
  There was inadequate consumption of iron, calcium and vitamin D. The vitamin B12 intake was considered adequate. There was statistically significant positive correlation between the time of surgery and the ingestion of iron, vitamin B12 and vitamin D.
  
  
  CONCLUSIONS
  The intake of iron, calcium and vitamin D of women one year after gastric bypass was inadequate, emphasizing the importance of multiprofessional monitoring postoperatively to prevent nutrient deficiencies.
