[Longitudinal study of health status of pilots: changes in body weight].

On the basis of medical monitoring of the flying personnel, their body weight variations as a function of age and disease were studied (trauma complications, malformations, refraction, color perception, obesity without concomitant diseases were ignored). The subjects were subdivided into two groups with respect to the age when the first chronic disease was detected. It was demonstrated that the airmen who remained healthy for a long period of time had body weight values close to the group mean and age-related body weight gain within normal limits. The subjects who fell ill when younger than 28 years had a high body weight and those who fell ill at the age of 28-32 years had a low body weight which increased drastically at the age of 30-35 years.
