“…In Spain, Moizé et al 10 evaluated 231 obese individuals and found a prevalence of hypovitaminosis D (<20 ng/mL) in 67.7% of them. Aridi et al 11 showed a prevalence of hypovitaminosis D in 91.5% of patients with obesity I or II in Lebanon, and 68.9% of them had levels below 20 ng/mL of this vitamin.…”

Study Design: Cross-sectional. Objective: Estimating the prevalence of hypovitaminosis D in a group of severely obese subjects referred to bariatric surgery. Methods: This study evaluated severely obese patients aged ≥18 years assisted by a specialized team in bariatric surgery. Clinical, anthropometric, and laboratory data were obtained from patient records. Plasma 25 (OH) D was determined by chemiluminescence and levels ≤ 20 ng/mL was considered as Hypovitaminosis D. The data were analyzed using the Statistical Package for Social Sciences® (SPSS) 20.0. Variables were described using descriptive statistics. For the comparison of the three groups, ANOVA, Kruskal-Wallis, and Pearson's chi-square tests were used. Spearman correlation test was performed to assess correlations between 25(OH)D and the other variables. P-values <0.05 were considered to be significant. Results: The study included 400 individuals, 71% were female with the mean age (SD) and BMI (SD) of 35.6 (9.1) years and 41.4 (5.1) kg/m², respectively. The vitamin D ranged from 4.5 to 62.4 ng/mL and the mean (SD) was 24.7 (7.9) ng/mL. In this sample, 117 (29.3%) individuals had hypovitaminosis D. There was a negative correlation between 25(OH)D and BMI (r= -0.110; p=0.028) and parathormone (r= -0.152; p=0.006) and positive correlation with serum calcium (r= 0.132; p=0.013) and phosphorus (r= 0.116; p=0.027). Conclusion: Severely obese subjects had a high prevalence of hypovitaminosis D even living in a sunny state.

“…In patients diagnosed with class II or class III obesity and referred for BS, vitamin D deficiency was verified, according to studies conducted in Brazil, Lebanon, and Singapore [ 60 , 61 , 62 ]. Ong et al (2018) [ 61 ] evaluated obese people submitted to BS in Singapore and perceived that vitamin D deficiency is prevalent, regardless of ethnicity; in particular, in the elderly, women, and those with a higher waist circumference and body fat percentage, being significantly associated with a lower vitamin D serum level.…”

(1) Background: Obesity and its comorbidities can cause burdens and limitations. Bariatric surgery (BS) is indicated as a safe procedure to reduce body mass and improve present comorbidities. However, several complications were reported, such as vitamin D [25(OH)D] deficiency. We evaluated if 25(OH)D serum levels relate to clinical characteristics, symptoms, or habits in women after their BS, and whether the vitamin D receptor (VDR) gene’s TaqI and FokI polymorphisms affected 25(OH)D levels and the total body bone mineral density (TBBMD). (2) Methods: This cohort cross-sectional comparative analytical prospective study consisted of 27 women, 61.6 ± 5.0 years, submitted to BS one year prior at a public reference hospital, DF-Brazil. All participants were asked to follow the physical and dietary activity recommendations and received vitamin D3 supplements. Their anthropometric, biochemical, and immunological measurements and blood samples were obtained. (3) Results: 73.3% of participants had low 25(OH)D levels, and their levels correlated positively with TBBMD and negatively with systolic pressure. VDR TaqI did not affect 25(OH)D levels, whereas VDR FokI’s allele f presence correlated to a median rise in 25(OH)D levels. Neither polymorphism correlated to TBBMD. (4) Conclusions: 25(OH)D levels were positively correlated with TBBMD, negatively with systolic blood pressure, and were higher in those with the VDR FokI allele f.

BACKGROUND: Vitamin, mineral, and metabolic deficiencies occur in the postoperative period of bariatric surgery, in the short and long term, and are worrisome intercurrences. AIMS: To evaluate the association of serum vitamin D levels with the lipid profile in obese patients undergoing bariatric surgery. METHODS: Case series of patients assisted from 2010 to 2018, in a private hospital of medium and high complexity, who underwent bariatric surgery using sleeve gastrectomy or Roux-en-Y gastric bypass techniques, monitored by the same surgeon. Sociodemographic, clinical, laboratory, and anthropometric data were collected preoperatively and at 6, 12, and 24 months after surgery. RESULTS: A total of 156 individuals, mostly female (75.6%) were monitored. The most frequent comorbidities were hepatic steatosis (76.3%) and hypertension (48.27). Regarding preoperative vitamin D levels, only 18.9% of the population had a satisfactory level (≥30 ng/mL). There was a reduction in weight and an improvement in the lipid profile after surgery. Significant correlations were observed between the lipid profile and vitamin D concentration only in the sample submitted to the Roux-en-Y gastric bypass technique: negative correlation between total cholesterol and vitamin D two years after surgery; positive correlation between triglycerides and vitamin D one year after surgery; and negative correlation between high-density lipoprotein and vitamin D two years post-surgery. CONCLUSIONS: It is essential to routinely monitor vitamin D levels and lipid profile pre- and postoperatively in order to avoid damage associated with this vitamin deficiency.
