Vitamin D and heart failure risk among individuals with type 2 diabetes: observational and Mendelian randomization studies.

What Was Tested

The paper reports a study of Vitamin D, K2, Magnesium and Zinc, published as an observational study.

This study aimed to investigate the associations of serum 25-hydroxyvitamin D [25(OH)D] with HF risk among individuals with T2D, in observational and Mendelian randomization (MR) frameworks.

Why It Was Studied

Evidence is limited and inconsistent regarding vitamin D and heart failure (HF) risk in people with type 2 diabetes (T2D), among whom vitamin D insufficiency or deficiency is common.

Who Took Part

The study group was 15,226 participants.

The age groups tagged for this paper are adults, middle-aged adults and older adults, both men and women.

Observational analyses were performed among 15,226 T2D participants aged 40-72 y from the UK Biobank.

MR analyses were conducted among 11,260 unrelated participants with T2D.

How the Study Was Run

HF incidence was ascertained through electronic health records.

A weighted genetic risk score for genetically predicted 25(OH)D concentration was instrumented using 62 confirmed genome-wide variants.

What Was Measured

The subject headings attached to it are Diabetes Mellitus, Type 2, Mendelian Randomization Analysis, Vitamin D, Heart Failure, Risk Factors and Vitamin D Deficiency.

Author keywords: 25-hydroxyvitamin D, cohort study and type 2 diabetes.

What This Means in Plain Language

This is an observational study of Vitamin D, K2, Magnesium and Zinc in 15,226 participants.

With several hundred people or more, it is a fairly large study for this kind of research.
