Aim. To establish parameters of physical activity (PA) and work capacity among men and women in an open population of Western Siberia city, depending on age.Material and methods. Cross-sectional epidemiological studies were carried out among open male and female population of a middle-urbanized city of Western Siberia (Tyumen). Representative samples of 1000 people aged 25-64 years (250 people in each life decade) were analyzed. PA and work capacity were determined according to the WHO MONICA-psychosocial questionnaire “Awareness and Attitude towards Health”.Results. Age-related trends among young men of middle urbanized Western Siberia city were manifested by PA increase during the last year (in 25-34 yearage group — in 20,9%, in the general population — in 13,8% (p=0,0205)). During the last year, a decrease and an increase in work capacity was revealed in young women (33,6%) and young men (17,5%), respectively. Age-related trends among middle-aged people of both sexes were manifested by low self-esteem — in men by the sixth decade of life (0,6% vs 8,9%, p=0,0002), in women — by the fifth decade of life (3,4% vs 8,2%, p=0,0442). In men, with a decrease in PA and work capacity during the last year, an increase in outdoor activities was revealed (15,8% vs 27,7%, p=0,0020).Conclusion. Since the promotion of physical literacy should be among the state priorities, the presented data can serve as the basis for planning populationbased preventive measures, intended for working-age men and women in middleurbanized Siberian cities.
