The study found people who exercise regularly have a lower risk of developing pneumonia and pneumonia-related death compared to those who were the least or not physically active. The relationship was shown for pneumonias that did not result in death and those that resulted in death. The results did not change on taking into account known factors that can affect pneumonia such as age, sex, body mass index, socioeconomic status, alcohol consumption, smoking, and pre-existing diseases. The strength of the association did not vary by age or sex.
