Combined effect of pulmonary rehabilitation and vitamin D supplementation on pulmonary function tests in asthma patients.

What Was Tested

This randomized controlled trial looks at Vitamin D, K2, Magnesium and Zinc.

To evaluate the Combined Effect of Pulmonary Rehabilitation and Vitamin D Supplementation on Pulmonary Function Tests in Asthma Patients.

Who Took Part

The abstract describes 90 adults taking part.

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

In this 12-week comparative interventional study, 90 adults (aged 30-55 years) with mild to moderate asthma and serum 25(OH)D < 30 ng/mL were randomized into three groups (n = 30 each): Group A (PR + vitamin D), Group B (PR only), and Group C (vitamin D only).

How the Study Was Run

The researchers set it up as a randomized study.

The adults were allocated by chance, so the Vitamin D, K2, Magnesium and Zinc group and the comparison group should start out alike.

Pulmonary function tests (FEV1, FVC, FEV1/FVC) and serum 25(OH)D levels were measured pre- and post-intervention.

Within-group and between-group differences were analyzed using paired t-tests and ANOVA with Tukey post-hoc tests.

What Was Measured

PubMed files the paper under topics including Asthma, Dietary Supplements, Vitamin D, Respiratory Function Tests, Cholecalciferol, Forced Expiratory Volume and Exercise Therapy.

The authors tagged it with the keywords airway inflammation, pulmonary function tests, pulmonary rehabilitation and vitamin D supplementation.
