[The dynamics of parameters of reproduction of Shor people - native small nation of the Kemerovo oblast].

In Russia, in the conditions of ongoing demographic crisis and socioeconomic transformations, the reproduction of population, including indigenous minorities, is the urgent problem. The analysis of dynamics of the age structure and reproductive parameters of women of three generations was carried out in order to determine the characteristics of reproduction of the Shors, the indigenous minority of the Kemerovo Region. The statistical data of population censuses (1970-2015), questionnaire materials, records of household books were used as sources of information. The average indices of the main parameters of reproduction of the Shors were calculated and their comparative analysis was carried out. The analysis of the reproductive characteristics of Shor women: the average age of the onset of menopause and menarche (climacterium is from 46.9±1.95 to 46.5±0.70 years, menarche from 14.5±0.65 to 13.9±0, 21 years old, p>0,05), the duration of the physiological reproductive period and the age of the woman at birth of the first child (22.5±0.42 years, 21.02±0.41 years, p>0,05) in a number of generations varied not statistically significant. There had been tendency of acceleration of rate of of process of puberty in female representatives of the "young" generation. The reproductive-active period reduced in 3 generations by 2 times (from 14.0 to 6.7 years). The age of woman at birth of the last child decreased from 36.5±0.65 to 27.7±1.09 years. The number of live-born infants decreased from 5.8±0.33 to 2.4±0.16 children. In women of all generations, there was high frequency of induced abortions (3.4±0.35 abortions). The negative dynamics of reproduction of the indigenous Shor population was established. The number of the Shors decreased from 14,059 people in 1970 to 10,672 people in 2010. The disproportion in gender ratio increased and absolute and relative volumes of pre-reproductive and reproductive contingents decreased. The Shors are characterized by narrowed mode of reproduction and regressive type of population age structure.
