Vitamin D Status, Bone Mineral Density, and Functional Exercise Capacity in Patients with Chronic Obstructive Pulmonary Disease

Abstract

Background: Chronic Obstructive Pulmonary Disease (COPD) a major world wide health issue, is considered through increasing air inflow restriction and systemic symptoms that go beyond the pulmonary system. Skeletal health and muscular function have drawn the most attention among these extra pulmonary symptoms because of their profound influence on patients' quality of life and general prognosis. Due mostly to calciferol's well-known roles in bone metabolism and muscular function, there has been a rise in interest in the supplement's potential contribution to the treatment of COPD in recent years. Objective: The correlations between vitamin D (calciferol) situation, bone mineral density (BMD), as well as physical ability to exercise were examined in this cross-sectional observational investigation including 120 people who had chronic obstructive pulmonary disease (COPD). Methodology: Participants were chosen from a medical institution and had to be at least 40 years older, with comprehensive data collected on demographics, COPD severity, Vitamin D status, BMD, and functional exercise capacity using standardized assessments. Statistical analyses, including correlation analyses and multivariate regression, were conducted to explore associations between variables. Results: In the study, it was discovered that blood 25(OH) D levels, a measure of the vitamin's status, substantially correlated with BMD around the joints of the hip & lumbar vertebrae. Participants with inadequate amounts of Vitamin D showed lower BMD than those with adequate levels. Even after controlling for possible confounders, calciferol level was still independently linked to increased functional exercise capacity as seen by a greater distance covered during the 6-minute walk test (6MWT). Conclusion: These results demonstrate that in COPD patients, Vitamin D level is closely related to skeletal health and functional exercise ability. Regular evaluation and treatment of calciferol insufficiency may have therapeutic consequences for reducing the risk of problems connected to the bones and improving the quality of life in people with COPD. It is necessary to do further study to examine the underlying processes and therapies that target Vitamin D levels in the treatment of COPD. Keywords: COPD; Vitamin D; Correlation; BMD; 6MWT
