A 2-Year Follow-Up After a 2-Year RCT with Vitamin D and Exercise: Effects on Falls, Injurious Falls and Physical Functioning Among Older Women.

What Was Tested

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

Who Took Part

By PubMed's age tags, the people studied were older adults and people over 80, women only.

A 2-year follow-up of a previous 2-year randomized controlled trial with vitamin D and exercise (Ex) of 409 older home-dwelling women using a factorial 2 × 2 design (D-Ex-, D+Ex-, D-Ex+, D+Ex+).

How the Study Was Run

In design terms this was 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 Accidental Falls, Bone Density, Exercise, Geriatric Assessment, Independent Living, Vitamin D and Wounds and Injuries.

Author keywords: Injurious falls and Physical functioning.
