Prevalence of dyslipidemia and its influencing factors in Kazakh adults

Objective To assess the prevalence of lipid disorders and its related risk factors among Kazakh adults aged 18 years and older.Methods Stratified cluster sampling was adopted to select 3 935 Kazakh adults aged 18 years and older in Xinyuan country,Shihezi city and other regions for a questionnaire survey and physical examination.Fasting blood samples were collected for serum lipids detection.Descriptive epidemiological method and multivariate logistic regression analysis were used to analyze the prevalence of dyslipidemia and its risk factors.Results The total prevalence of dyslipidemia among the adults was 40.9%,with a standardized rate of 40.8%.The prevalence rates of hypertriglycerdemia,high total cholesterol(TC),high low-density lipoprotein cholesterol(LDC-c),and lowhigh-density lipoprotein cholesterol(HDL-c)were 19.4%,14.5%,7.7%,and 16.1%,with the standardized rates of 18.7%,12.6%,6.3%,and 18.5%,respectively.The prevalence of dyslipidemia in the males was 46.5%,higher than that of the females(37.2%,χ²=33.865; P=0.000).Multivariate logistic regression analyses showed that gender and body mass index(BMI)were risk factors of dyslipidemia(odds ratioOR=1.809,95% confidence intervalCI:1.307-2.503; OR=1.835,95% CI=1.329-2.535).The amount of tea drinking,intakes of vegetables and fruits were protective factors for dyslipidemia(OR=0.588,95% CI:0.463-0.746; OR=0.591,95% CI:0.419-0.835).Conclusion The prevalence of dyslipidemia in Kazakh adults was higher than that of the national average,especially for high hypertriglyceridemia and lowHDL-c hyperlipidemia.The prevalence of dyslipidemia demonstrates an increase trend among the young adults.
