简要总结
This study aims to assess the impact of preoperative anemia status on anemia and related nutrient abnormalities 1 year after bariatric surgery.
详细描述
This study aims to assess the impact of preoperative anemia status on anemia and related nutrient abnormalities (ferritin deficiency, vitamin B12 deficiency, folate deficiency, and low transferrin saturation level) at 1 year after bariatric surgery.

结局指标
主要结局
Odds ratio (OR) for anemia by preoperative anemia status
时间窗: 1 year
Multivariable logistic regression will be performed to assess the association between preoperative anemia and postoperative anemia. Several factors will be adjusted: sex, age, BMI, waist circumference, hip circumference, surgery, smoking, alcohol, hypertension, diabetes, hyperuricemia, hypercholesterolemia, and hypertriglyceridemia.
次要结局
- Percentage of ferritin deficiency(1 year)
- Percentage of anemia severity(1 year)
- Percentage of postoperative anemia(1 year)
- Percentage of folate deficiency(1 year)
- Percentage of vitamin B12 deficiency(1 year)
- Percentage of low transferrin saturation level(1 year)
