Incidence of rachit in children of Tajikistan

   Aim. To study the incidence of rachitis in children of Tajikistan.   Materials and methods. The main methodology used in the analysis of the incidence of rickets was a retrospective study (conducted between 2009 and 2016), using descriptive and analytical methods of modern epidemiology. The mean value (M) and mean error (m) were calculated, and the annual average rate of increase and decrease (Tpr/dec, %) were calculated. The dynamic analysis of rachitis incidence rates covered a 7-year interval.   Results. An analysis of the incidence of rickets over a 7-year period showed that in 2009 the incidence rate across the country was 40733.4 %, and in 2016 it decreased to 13500.9 %. The rate of decline for this period was 66.8 %, and the average annual rate of decline was 9.5 %. In 2009, the incidence rate among rural residents was 72990.2 % which is 1.6 times higher than in the city. After seven years, the incidence rate tended to decrease but remained 1.9 times higher than in the city. The highest rate of rickets was found among children 1 year of age.   Conclusion. The highest incidence rate of rickets was found in in 2009 in GBAO , Dushanbe, and RRS. In these regions, the rate of decline in 2016 was also significant. The morbidity rate among children living in rural areas in the analyzed years tended to decrease by 3.9 % on average. The highest incidence rate of rickets was found among children of 1 year of age.
