A deficient vitamin D status is linked to increased risk of community-acquired pneumonia (CAP) and both short- and long-term mortality. This prospective cohort study, nested within the Surviving Pneumonia Study at Copenhagen University Hospital—North Zealand, included adults hospitalized with CAP between 2019 and 2022. The study assessed vitamin D status using serum 25(OH)D concentrations and categorized participants as sufficient, insufficient, or deficient. The findings suggest that vitamin D deficiency is associated with higher mortality rates in hospitalized CAP patients.
