[The problem of obesity in children from the mountains and the city].

The problem of obesity has been investigated on 547 children from the mountains and the city by a questionary and by measuring skinfolds and body weight. The ratio of obesity is very high specially in children of the city and in parents of both groups. Obesity of parents, small sportif activity and nearly daily watching television was found to favour obesity of the children. Factors against obesity are the hard work of children in the mountains and large sportif activity. The mean values of body weight and skinfolds partially differ very much from the median values and cannot be used as norm.
