[Occupational aging (biological age modeling)].

Based on workers' biologic age, the authors created a systemic model of general and occupational ablebodiedness and tested the model on selective determination of biologic age among workers of various Ukrainian regions. The results proved increase in occupational aging of the population. General and occupational ablebodiedness in males of the select was lower than that in the females.

[Experience with the use of a low-calorie diet in breast cancer patients to prevent metastasis].

The paper discusses results of three-year follow-up of breast cancer patients keeping to a low-calorie diet after radical mastectomy and chemotherapy. The diet was planned according to age, energy expenditures and body weight and was aimed at a 15% decrease in the total caloricity as compared to corresponding individually-tailored norms for healthy people. This was achieved by reduction in fat (by 30%) and carbohydrates (by 9%).

[Characteristics of nutrition in persons of older age groups in areas with different patterns of longevity].

The study of actual nutrition in old-aged subjects (60-74, 75-89 and 90 years and older) in the regions with varying levels of long-living has revealed different types of nutrition depending on the climatic and geographical zones. The character of nutrition of old-aged in varying regions permits a suggestion on the relation of long-living with low energy requirements that are formed under the influence of ecological conditions (high temperature and humidity of the air in Abkhazia) and determined genetically (Azerbaijan, Ukraine). Alteration of nutrition type according to the environmental requirements (as adaptation to high temperature), decreased energy value of food approaching the nutrition type of the indigenous population (for example, the Azerbaijans and Russians living in Azerbaijan) do not ensure long-living.

[Characteristics of actual nutrition of the long-lived population of Azerbaijan].

The assay of the actual nutrition of old people living in Azerbaijan has evidenced that it corresponds to the climatic and geographical features of the region and has a direct relation to the long-living. The actual nutrition of old subjects in the Azerbaijan SSR is characterized by low fat consumption (vegetable oils among them), by low value of the ratio between polyunsaturated and saturated fatty acids, by high consumption of fruit and vegetables as well as fermented milk products, by an optimal water-salt regimen, high content of vitamins and antioxidants, geroprotectors and a comparatively low energy value of the food rations.

[Bases of rational nutrition in old age].

Current theoretical concepts of gerontological dietetics have been analysed. Elaboration of rational nutrition patterns for the old should rest on the age-specific metabolic and functional changes in the organism. A possibility of influencing the acid-base balance of the blood, immunity, and intestinal microflora by means of a goal-oriented diet has been demonstrated.
