Congenital Anomalies of Circulatory System among the Pediatric Population in Kazakhstan: Space and Time Assessment of Incidence

4 Abstract: The purpose of study is to investigate the epidemiological features of the incidence of congenital anomalies of circulatory system (CACS) among children in the whole country and its regions. The epidemiological characteristics of the disease incidence are described in the research. This is a retrospective study for the years 2003-2011. The main source of study materials was summary report from the Ministry of Public Health of the Republic of Kazakhstan (Form 12), about children, patients with CACS (International Classification of Diseases-Q20-Q28), in general, established for the first time in life. We used descriptive and analytical methods of modern epidemiology. For space-time assessment of the under study pathology in children, the method of compiling cartograms was used, based on the definition of a standard deviation ( ) from an average of (x). It is found that 73.3% of CACS fall on the child population under the age of 15. The CACS average annual incidence among children in the whole country amounted 152.0±14.7 / . The adjusted incidence rate trends tended to increase (T=+12.0%). A space and time 0 0000 incidence was assessed according to the administrative division with the following morbidity levels: low-up to 99.3 / , average - from 93.3 to 208.9 / and high - from 208.9 / and above. The incidence trends of all 0 00 0000 0000 0000 the studied regions tended to increase and the rates of increase were most registered in South Kazakhstan (T=+29.6%) and Pavlodar (T=+36.5%) regions. The results of the CACS incidence indicate intensive growth of this disease among the pediatric population of Kazakhstan. Perhaps, this is due to the inefficacy of undertaken prevention, or, it could be explained by the improved diagnostic measures. Also, on the cartogram, a high incidence rate was revealed in the regions with adverse environmental conditions.
