| Abstract | |
Crohn\'s disease (CD) is an inflammatory bowel disease whose most common symptoms are diarrhea, abdominal pain and fever. As a result, weight loss and malnutrition are the most prevalent nutritional disorders due to many factors: decreased intake, poor absorption, increased intestinal losses and increased energy demand. As many factors may compromise the nutritional status and quality of life of these patients, it is important to study their dietary and nutritional profile. Thus, the aim of this study is to assess the dietary intake and nutritional status of Crohn\'s disease outpatients. The nutritional status was based on biochemical tests, body composition and body mass index. Food intake was evaluated by an alternate three-day Food Record, and the adequacy of intake was evaluated according to national and international references. The study included 217 patients and 65 controls. Out of the patients, 54.4% were classified as normal-weight, but the mean body mass index was lower than controls (23.8 vs. 26.9 kg/m2, p = 0). The body mass index of patients with bowel resection was lower than those without resection (23.1 vs. 24.4 kg/m2, p = 0.045). Vitamin B12 deficiency was 19% among patients and 9% among controls, being more common in patients with the disease located in the ileum (23%) and bowel resection (23%). Vitamin B12 levels were negatively correlated with CRP (r = -0.13, p = 0.059). The 25- hydroxyvitamin D insufficiency was 63% among patients and 74% among controls, and was more common in patients with CRP > 3mg / l (69%), whereas the deficiency reported was 6% among patients and 3% among controls, and those who presented with deficiency had the disease over long periods of time (13.9 years). Patients had lower cholesterol levels (163.9 vs. 180.7 mg/dl, p = 0.001) and LDL (83.9 vs. 109.9 mg/dl, p = 0) and higher HDL (56.6 vs. 51.1 mg/dl, p = 0.026) and triglycerides (121.7 vs. 100.7 mg/dl, p = 0.091) than controls, and the same was reported in those patients with intestinal resection. Anemia was present in 20% of patients and only 3% of controls, being more common in those patients with CRP > 3mg/l (25%) and bowel resection (23%). Although 54.4% of patients did not attain 90% of estimated energy requirement, this inadequacy was more common in controls (89%). Patients and controls had modestly adequate consumption for macronutrients and fiber, but higher protein intake than controls. Active patients had higher intake of cholesterol but lower intake of fibers. Inadequate intake of micronutrients was high and similar between patients and controls for vitamin D, E and calcium, and higher in patients for selenium, zinc and vitamins B1, B3, B6, B12 and C. There was a high prevalence of patients and controls with low consumption of \"cereals, tubers and roots\", fruit, vegetables and dairy products, and high consumption of \"meat and eggs\", \"sugars and sweets\" and \"oils and fats\". Although the quality of the diet did not differ greatly between patients and controls, and considering that there was a high proportion of controls with low energy intake and that the CD patients\' nutritional status improved due to the characteristics of the disease, these patients remain at nutritional risk. Therefore, it is imperative to continuously monitor their nutritional status, mainly those presenting with higher nutritional risk, patients with active CD, CRP > 3mg/l, bowel resection and those with CD over long periods of time (AU) | |
