研究概览
简要总结
Bariatric surgery patients tend to have malabsorption of many micronutrients such as B12, Iron and vitamin D postoperative. So in this study, a monthly high dose of vitamin D3 is giving to patients with their routine supplements and followed up for 6 months.
Hypothesis:Bariatric surgery subjects taking monthly high dose cholecalciferol supplements in addition to the standard vitamin D protocol will have a significant rise in serum vitamin D levels compared to the subjects taking only the usual vitamin D protocol.
详细描述
Sun exposure and supplement use questionnaire:
A registered dietitian asked each subject for information on sun exposure, vitamins, medications, and any other supplement usage before each blood sample was taken.
Lab analysis included serum hydroxy vitamin D levels pre and 3 months postoperative.
Descriptive statistics which include both the means and standard deviations were calculated on the study variables. A paired sample t-test was used to determine if there was a significant difference in mean values pre and post vitamin D supplementation. An independent sample t-test was used to assess for significant differences in group (control vs. vitamin D supplement) means. A p-value < 0.05 was considered statistically significant. Statistical analyses were done using SPSS Version 21 (SPSS, Chicago, III, USA).

主要结局
Impact of monthly high dose oral cholecalciferol on serum 25 hydroxy vitamin D levels in bariatric surgery subjects
时间窗: one year
To determine if there is a significant difference in mean serum vitamin D levels in the group of subjects taking the standard vitamin D protocol compared to subjects taking the standard vitamin D protocol with added monthly high dose cholecalciferol after bariatric surgery. This outcome measure is done by analysis of serum 25-OH vitamin D levels.
