Abstract

Hypercholesterolemia is a major risk factor for cardiovascular disease, the leading cause of death in Kazakhstan. Understanding its prevalence is vital for effective public health planning and interventions. This study aimed to assess the scale of hypercholesterolemia in the Republic of Kazakhstan and to identify differences among distinct population groups. A cross-sectional study involving 6720 participants (a nationally representative survey.) aged 18-69 was conducted from October 2021 to May 2022 across all 17 regions of Kazakhstan. The magnitude of hypercholesterolemia was 43.5%. Cholesterol levels were determined through blood biochemical analysis. Age, sex, geographic location, and ethnicity served as covariates. The majority of participants (65.49%) were from urban areas with an almost equal gender distribution (50.07% male and 49.93% female). The predominant age groups were 18-29 years (25.71%) and 30-39 years (25.12%), and 65.09% identified as Kazakh. The prevalence increased with age, with the 60-69 age group showing the highest rate at 71.14%. Women had slightly higher rates than men. Geographical differences were evident, with regions like Astana city and Almaty region showing significant disparities. Kazakhs had a lower rate compared to other ethnicities. Age, region, and BMI were significant predictors for hypercholesterolemia in both binary and multivariate logistic regression analyses. The study revealed a significant prevalence of hypercholesterolemia in Kazakhstan, with increasing age as a major determinant. Women, especially those over 50, and certain regions showed higher cholesterol levels. The disparities observed across regions and ethnicities suggest the need for targeted public health interventions to address this pressing health concern.
