Associations between objective and self-reported physical activity and vitamin D serum levels in the US population

摘要

Both low levels of vitamin D and of physical activity are associated with all-cause, cancer, and cardiovascular disease mortality. There is some evidence based on self-reported activity levels that physically more active individuals have higher vitamin D serum levels. The aim was to investigate associations between objectively measured and self-reported physical activity, respectively, and vitamin D serum concentrations in the US population.
