Effect of one-anastomosis gastric bypass on cardiovascular risk factors in patients with vitamin D deficiency and morbid obesity: A secondary analysis.

What Was Tested

The paper reports a study of Vitamin D, K2, Magnesium and Zinc, published as a randomized controlled trial.

Bariatric patients often suffer from vitamin D (VD) deficiency, and both, morbid obesity and VD deficiency, are related to an adverse effect on cardiovascular disease (CVD) risk.

Therefore, the researchers assessed the change of known CVD risk factors and its associations during the first 12 months following one-anastomosis gastric bypass (OAGB).

Who Took Part

PubMed indexes the participants as adults and middle-aged adults, both men and women.

How the Study Was Run

The researchers set it up as a randomized and double-blind study.

Because people in this Vitamin D, K2, Magnesium and Zinc study were split into groups at random, differences between the groups are less likely to reflect who happened to join each one.

Neither the participants nor the staff measuring them knew who was on Vitamin D, K2, Magnesium and Zinc, so expectations could not easily colour the readings.

What Was Measured

Topics PubMed links to this paper include Austria, Biomarkers, Cardiovascular Diseases, Cholecalciferol, Dietary Supplements, Gastric Bypass and Heart Disease Risk Factors.

The authors tagged it with the keywords Cardiovascular risk factors, Ferritin, Insulin resistance, Obesity, One-anastomosis gastric bypass and Vitamin D.
