“…Also, the results showed that ethnic Russians experience higher mortality rate on dialysis than other ethnicities. While we did not investigate the reasons for the observed difference, the results seem to be in agreement with previous studies that reported higher mortality rate among ethnic Russians in central Asia compared to other ethnicities, including Davletov and colleagues who studied mortality rates in Kazakhstan by ethnic group and the most commonly reported contributing factors [ 22 ]. The study reported that despite having higher levels of education and socioeconomic status than Kazakhs, ethnic Russians in Kazakhstan appear to have a higher mortality rate than other ethnicities.…”

Background The epidemiology of dialysis patients has been little studied in developing countries and economies in transition. We examined the prevalence, incidence and mortality rate of dialysis patients in Kazakhstan, via aggregation and utilization of large-scale administrative healthcare data. Methods The registry data of 8898 patients receiving dialysis therapy between 2014 and 2018 years were extracted from the Unified National Electronic Health System (UNEHS) and linked with the national population registry of Kazakhstan. We provide descriptive statistics of demographic, comorbidity and dialysis-related characteristics. Results Among all patients undergoing maintenance dialysis for end-stage renal disease (ESRD), there were 3941 (44%) females and 4957 (56%) males. 98.7% of patients received hemodialysis and 1.3% peritoneal dialysis. The majority of the patients (63%) were ethnic Kazakhs, 18% were Russians and 19% were of other ethnicities. The prevalence and incidence rate in 2014 were 135.2 and 68.9 per million population (PMP), respectively, which were different in 2018 [350.2 and 94.9 PMP, respectively]. Overall mortality rate among dialysis patients reduced from 1667/1000 patient-years [95%Confidence Interval (CI): 1473–1886] (PY) in 2014 to 710/1000PY [95%CI: 658–767] in 2018. We observed 13% lower crude survival probability in females compared to males and in older patients compared to younger ones. Russian ethnicity had 58% higher risk of death, while other ethnicities had 34% higher risk of death compared to in those of Kazakh ethnicity. Conclusion We describe for the first time in Kazakhstan an increase in the prevalence and incidence of ESRD on dialysis, while mortality rate decreased over time, during 2014–2018. We observed statistically significant lower survival probability in female dialysis patients compared to males, in older patients compared to younger ones, and in patients of Russian ethnicity compared to Kazakh.

“…Apart from that, no ethnic differences were detected between the Kazakh and Russian groups in terms of risk factors such as diabetes mellitus and smoking. According to previously published reports, in rural areas, the Russian population smokes more than the Kazakh (21,41). In our case, the absence of a difference may be associated with the urban conditions of the observed population.…”

The study aimed at the determination of risk factors, their relationship with the development of stenosing lesions of the coronary arteries in different ethnic groups in Kazakhstan. Primary coronary angiographies of n=640 patients diagnosed with coronary heart disease (CHD) (2017-2019) have been analysed (Almaty, Kazakhstan). The patients were subdivided into: Kazakhs (n=338) and Russians (n=302). In the Russian group, the chance of arterial hypertension incidence was higher (44% and 33%, p<0.05). In the Russian group, the percentage of obstructive CHD was higher than in the Kazakhs (66% and 57%, p<0.05). There was association between obstructive CHD and risk factors such as male sex, diabetes, smoking, and diastolic blood pressure (DBP) in the Kazakhs (p<0.05). In the Russian group, the relationship between development of CHD and age, level of total cholesterol and high-density lipoprotein (HDL) was higher (p<0.05). There is an association between smoking, diabetes, sex, DBP and the development of CHD in Kazakhs. In the Russian group, CHD was associated with risk factors such as older age, dyslipidaemia and arterial hypertension. There were significant ethnic differences in the risk factors and CHD, in the Russian group the probability of development of obstructive CHD was higher. There was an association between smoking, diabetes, sex, DBP and the development of CHD in Kazakhs. In the Russian group, CHD was associated with risk factors such as older age, dyslipidaemia and arterial hypertension. These finding indicate the need to develop differentiated programmes for the screening, preventive measures for different ethnic groups.

“…We found only small differences in abnormal lipid prevalence by education and car ownership, and deprivation levels were inversely associated with increased odds of dyslipidemias. The higher prevalence of dyslipidemia in ethnic Russians in Kazakhstan in this study may reflect differences in lifestyle and particularly in nutrition [ 31 ]; however, in absence of reliable individual-level data on nutrition this is only a speculation.…”

Prevalence, awareness, treatment and control of dyslipidemia in older persons in urban and rural population in the Astana region, Kazakhstan

BackgroundDespite high cardiovascular mortality in Central Asian republics of the former Soviet Union, there is limited information about major risk factors, including blood lipids. We investigated the prevalence of impaired concentrations of blood lipids, the awareness, treatment and control of hypercholesterolemia, and factors associated with these indicators in urban and rural populations in Kazakhstan.MethodsWe conducted a cross-sectional study of random urban and rural population samples (the state capital Astana and Akmol village). Men and women aged 50–74 years were examined; a total of 954 adults participated (response rate 59%). Serum concentrations of total, LDL and HDL cholesterol and triglycerides and a range of other cardiovascular risk factors were measured.ResultsThe overall prevalence of hypercholesterolemia (total cholesterol ≥6.2 mmol/l) was 37%; among subjects with hypercholesterolemia, 57% were aware of their condition, 41% took medication and 23% had total cholesterol <6.2 mmol/l (4.5% <5 mmol/l). The prevalence, awareness, treatment, and control of hypercholesterolemia were all higher in the urban than the rural area. Similarly, the proportions of subjects with impaired concentrations of specific lipids fractions were also considerably higher in the urban population. Most associations with other covariates were in the expected direction.ConclusionsThis study found relatively high prevalence of dyslipidemia in the Kazakh population, and the blood lipid profile was less favourable in the urban area. These pronounced urban–rural differences may be related to urbanization, the associated nutrition transition and to access to health care.Electronic supplementary materialThe online version of this article (doi:10.1186/s12889-017-4629-5) contains supplementary material, which is available to authorized users.
