The prevalence of adiposity and nutritional status among the working population of seven regions in the Ukrainian SSR (teachers, workers engaged in the chemical, metallurgical, textile, wood-working industries and in agriculture) were studied. Only 44 per cent of males and 25 per cent of females were found to be of normal weight. Some surplus weight had 21 per cent of men and 26 per cent of women, 9 per cent of men and 21 per cent of women suffered from adiposity of the 1st degree and 2 per cent of males and 15 per cent of females had adiposity of the II degree. The nutrition of the obese was more rich in calories at the expense of bread-stuffs, potato, pure carbohydrates and some products of animal origin (fats). Overweight and obesity were observed more often among teachers of both sex and also among female-workers of cotton factories and smelters. The proportion of the patients with cardiovascular diseases and metabolic disorders was higher among the obese. These data witness the need for differentiation of nutritional standards depending upon the energy spent by the representatives of individual occupational groups of the population.
