A team of investigators examined the relationship between leisure-time physical activity and suspected bacterial infections during a one-year follow up.
The risk of viral infections is known to be affected by physical activity. But, there is insufficient evidence regarding the more serious bacterial infections. Suspected bacterial infections were determined based on prescriptions for antibiotics.
Via the use of Denmark's unique civil registration number (an identification number assigned to all citizens at birth), it was possible to link health survey information with information from nationwide registries.
Further, low and moderate levels of leisure-time physical activity were associated with a 21 percent and 32 percent reduction of suspected cystitis (urinary tract bacterial infections), respectively - compared with individuals classified as sedentary.
Suspected respiratory tract bacterial infections, however, were not associated with physical activity level.
