Abstract
BACKGROUND: Two main causes for nutrient deficiencies following bariatric surgery (BS) are pre-operative deficiencies and favoring foods with high-energy density and poor micronutrient content. The aims of this study were to evaluate nutritional status and gender differences and the prevalence of nutritional deficiencies among candidates for laparoscopic sleeve gastrectomy (LSG) surgery. METHODS: A cross-sectional analysis of pre-surgery data collected as part of a randomized clinical trial on 100 morbidly obese patients with non-alcoholic fatty liver disease (NAFLD) admitted to LSG surgery at Assuta Medical Center between February 2014 and January 2015. Anthropometrics, food intake, and fasting blood tests were evaluated during the baseline visit. RESULTS:One-hundred patients completed the pre-operative measurements (60 % female) with a mean age of 41.9 ± 9.8 years and a mean BMI of 42.3 ± 4.7 kg/m(2). Pre-operatively, deficiencies for iron, ferritin, folic acid, vitamin B1, vitamin B12, vitamin D, and hemoglobin were 6, 1, 1, 6, 0, 22, and 6 %, respectively. Pre-surgery, mean energy, protein, fat, and carbohydrate intake were 2710.7 ± 1275.7 kcal/day, 114.2 ± 48.5, 110.6 ± 54.5, and 321.6 ± 176.1 gr/day, respectively. The intakes for iron, calcium, folic acid, vitamin B12, and vitamin B1 were below the Dietary Reference Intake (DRI) recommendations for 46, 48, 58, 14, and 34 % of the study population, respectively. CONCLUSION: We found a low prevalence of nutritional deficiencies pre-operatively except for vitamin D. Most micronutrient intake did not reach the DRI recommendations, despite high-caloric and macronutrient intake indicating a poor dietary quality.
