Background: Stroke morbidity and mortality rate varies depending on the level of economic and social development of the resident country, geographical region, as well as ethnicity and sex attribute. The aim of the study is to identify special aspects in morbidity and mortality rates among patients with intracerebral hemorrhages considering age, sex and ethnic differences in Kazakhstan. Methodology: The study included 1,657 patients hospitalized in Kazakhstan between 2018 and 2020. Results: In the study, we found that the average age at admission was significantly lower for male patients (59.96 years) compared to female patients (64.31 years). The overall mortality rate, including both in-hospital and within 30 days after discharge, was 35%. The distribution of mortality by age and sex showed statistically significant differences by ethnicity, with distinct patterns observed among patients of Kazakh and other ethnic groups. Conclusions: Further detailed studies focused on identifying and preventing intracerebral hemorrhage risk factors are necessary to validate these results.
