Mortality

The mortality rate is the frequency of deaths among the population; is determined by the ratio of the number of deaths per 1000 population (PPT). There are the General mortality and mortality of children under the age of 1 year (see child mortality). You should distinguish between mortality and mortality (see). The latter characterizes mortality among patients and calculates the number of deaths per 100 patients.
Mortality during the last decades has sharply decreased. Especially sharply decreased mortality in the Soviet Union (see Union of Soviet Socialist Republics). So, in 1971 mortality in the USSR was 8.2 per 1000 population (compared with mortality in pre-revolutionary Russia, has decreased more than 3.5 times). Even more decreased child mortality. Mortality rates vary by age. The lowest death rate is marked in the age from 5 to 19 years, then it is increased in each age group. The highest mortality rates occur in children under 1 year of age and those aged 70 and over. The mortality rate in combination with indicators of birth rate (see), morbidity (see) and physical development (see) characterizes the state of health of the population (see).
The death rate of the population is dependent on morbidity. In the early 20th century the leading causes of mortality, communicable diseases. Currently in the USSR and in all economically developed countries, thanks to advances in medical science and dramatically improved sanitary improvement, increase of culture of the population infectious diseases do not play a significant role in the mortality of the population. The main causes of mortality in the developed countries are heart disease, vascular and malignant neoplasms. Further reduction of mortality in the USSR depends on the reduction of child mortality and mortality from chronic diseases, primarily of heart disease and blood vessels and malignant neoplasms, which largely determine the mortality of the elderly.
The success of the struggle for reducing mortality depends on the socio-economic conditions, quality of medical aid to the population. In the further reduction of mortality along with the growth of welfare and culture of the population a greater role should be played by the successes of medical science, improvement in the health authorities. In the struggle to reduce mortality, along with doctors play an enormous role nurses. Especially important role in the fight against disease, child mortality and mortality, the reduction of which is a significant reserve in the further reduction of mortality.
