Abstract: Objective:To assess the nutritional status of obese patients prior to bariatric surgery, and to explore the related factors of nutrient deficiency.Methods:Clinical data of 43 patients with obesity who underwent bariatric surgery at Beijing Hospital from Jan. 2011 to Dec. 2017 were retrospectively analyzed. Gender, age, BMI, body composition analysis data, blood test data of nutrients were collected. The software of SPSS 20.0 was used to conduct data analysis.Results:Nutrients deficiencies were found for vitamin D (100.0%), iron (26.1%), prealbumin (15.4%) and hemoglobin (7.0%). Hemoglobin, prealbumin, and serum iron levels were significantly higher in male patients than in female patients ( P=0.001, 0.000 and 0.001, respectively). Body fat percentage was negatively correlated with 25 hydroxyvitamin D ( r=-0.983, P=0.017), and positively correlated with serum sodium ( r=0.568, P<0.001). Conclusions:Obesity patients were presented with a variety of nutritional deficiencies before bariatric surgery. A comprehensive nutrients test should be performed before bariatric surgery, to detect and correct nutrient deficiencies preoperatively.
