Vitamin D Status and Longitudinal Changes in Body Composition in Patients with Chronic Obstructive Pulmonary Disease - A Prospective Observational Study.

What Was Tested

This observational study looks at Vitamin D, K2, Magnesium and Zinc.

This study aimed to evaluate the association between vitamin D levels and status with body composition (BC), as well as with its changes over time.

Multiple linear regression analyses were performed to assess the relationships between 25(OH)D (nmol/l) and longitudinal changes in BMI, fat-free mass index (FFMI), fat mas index (FMI) and bone mineral density (BMD).

Why It Was Studied

Alterations in body weight and composition are common in patients with chronic obstructive pulmonary disease (COPD) and are independent predictors for morbidity and mortality.

Low vitamin D status is also more prevalent in patients with COPD compared to controls and has been related to lower lung function, muscle atrophy and impaired musculoskeletal function.

Who Took Part

By PubMed's age tags, the people studied were middle-aged adults and older adults, both men and women.

Patients with COPD and controls without COPD, participating in the Individualized COPD Evaluation in relation to Ageing (ICE-Age) study, a prospective observational study, were included.

What Was Measured

The subject headings attached to it are Pulmonary Disease, Chronic Obstructive, Vitamin D, Bone Density, Vitamin D Deficiency, Body Composition, Absorptiometry, Photon and Lung.

The authors tagged it with the keywords bone mineral density, chronic obstructive pulmonary disease, fat-free mass and longitudinal changes.

What This Means in Plain Language
