title: [Spinal diseases and professional longevity of flying personnel].
abstract: Analyzed were histories of medically discharged (n = 727), physically qualified (n = 807), pilots and navigators, and flying personnel (n = 372) who had been repeatedly tested in one and the same hospital at the age of 34-36 yrs and 38-41 yrs. Spondylosis deformans is diagnosed more frequently in medically discharged than qualified flyers but, according to the covariation analysis, this is explained by elder age of the discharged persons. Physically fit persons with SD diagnosed at the age of 30-40 are prone to be grounded earlier than healthy persons. Compared with persons having other diagnoses, flying career (FC) will have longer if SD was stated at the age of 30, same if SD was stated at the age of 35, and shorter if SD was diagnosed at the age of 40. These differences remain statistically significant after covariation correction for specialty, age of entering military school and number of chronic diseases.
