Abstract Objective. To evaluate vitamin D deficiency and body composition of women submitted to bariatric surgery and relate their body mass index variation after surgery to 25(OH) D concentrations. Method. A cross-sectional and controlled study was performed including 49 obese adult volunteer women, submitted to Roux-en-Y gastric bypass (RYGB group). Collected Data. Body mass index (BMI), self-declared ethnicity, economic condition, physical activity level, serum concentrations of 25-hydrox-ycholecalciferol (25(OH) D

radioimmunoassay), parathormone, and body composition by dual-energy X-ray absorptiometry (Hologic DXA-QDR-1000) were collected. Results. 25(OH) D deficiency was found in 27 (55.1%) and 8 (21.1%) in the RYGB and control groups (p = 0.002). Secondary hyperparathyroidism was more frequent in the RYGB group compared to the control group (15 (30.6%) versus 1 (2.6%)

p = 0.001).. ere was no relation of the studied variables and body composition with 25(OH) D deficiency. 25(OH) D concentrations were correlated (r = -0.531

p < 0.001) with BMI reduction, regardless of vitamin D supplementation. Conclusion. Women submitted to bariatric surgery (RYGB) around three years ago had higher BMI and vitamin D deficiency, along with hyperparathyroidism, compared to the control group.. ere was no association between variables related to body composition and 25(OH) D concentrations. On the other hand, vitamin concentrations correlated negatively to BMI variation after undergoing surgery.
