In chronic obstructive pulmonary disease (COPD), simultaneous vitamin D-, magnesium- and calcium deficiency is associated with increased risk of exacerbations, whereas associations with other aspects of COPD, i.e. lung function and quality of life (QoL), have been less extensively studied.AimTo investigate the relationship between serum vitamin D, magnesium and calcium in COPD and the effects of these three parameters on lung function and QoL in COPD patients.MethodsThe lung function test and blood samples were measured. The patients were characterized as well as their overall and the COPD-related QoL.ResultsThis cross-sectional study included 143 patients with COPD.Lung function was not correlated with serum vitamin D3 (25-(OH)D3), magnesium or calcium in COPD. Furthermore, the patients’ history of exacerbations and the overall and the COPD-related QoL showed no correlation with serum vitamin D, magnesium or calcium.DiscussionWe found no correlation between the lung function or QoL and the serum vitamin D, magnesium or calcium in COPD. Our findings are supported by most of the relatively sparse studies on the topics. ER -
