Effects of dietary improvement on bone metabolism in elderly underweight women with osteoporosis: a randomised controlled trial.

What Was Tested

Researchers studied Vitamin D and Calcium in the context of osteoporosis and bone density in this randomized controlled trial publication.

Malnutrition in elderly people contributes to osteoporosis and fracture.

A 12-month randomized controlled trial of 71 ambulant women aged > or =70 years with BMI < or =21 kg/m(2 )and osteoporosis at the hip was undertaken.

Who Took Part

According to the abstract, 71 women were involved.

PubMed indexes the participants as older adults, women only.

How the Study Was Run

The design is described as randomized.

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

Body composition and bone mineral density (BMD) were assessed at baseline and 12 months.

Biochemical markers of bone turnover were measured at baseline and at 1, 3, 6, 9 and 12 months.

What Was Measured

The subject headings attached to it are Alkaline Phosphatase, Anthropometry, Body Composition, Body Mass Index, Bone Density, Bone and Bones and Calcium.

What This Means in Plain Language

The paper is a randomized study of Vitamin D and Calcium in 71 women in people with osteoporosis and bone density.

The publication is from 2003 (Osteoporosis international : a journal established as result of cooperation between the European Foundation for Osteoporosis and the National Osteoporosis Foundation of the USA), a journal based in England.
