 formation of this type of activity is due to the deteriorating health 
of the population that required addressing health and social issues to a
 new level - at the level of socio-medical work.
  
Medical
 studies mainly anatomical and physiological condition of the human body
 as a whole and its separate systems, identifying deviations from the 
physiological norm, diagnose pathological changes in the body, determine
 cause and effect relationships underlying the mechanisms of disease. 
 It uses different methods for a full recovery of the body, normalizing its physiological processes. The
 tasks of social work include the identification of major factors that

their combinations on human health, almost no studies of society and the
 economic condition of families, in particular provision of the 
necessities for human life: housing, employment, transportation, food, 
no studies are demographic indicators: incidence, fertility,

economic conditions of residence and its effect on human health.
