Abstract:
Objective:To determine the prevalence of dyslipidemia in students from the primary and middle schools and the influential factors,and to provide evidence for the prevention and control of dyslipidemia and relevant chronic diseases in primary and middle schools.Methods:A total of 2 028 students aged 7 to 17 from the primary and middle schools in Changsha were selected by stratified random cluster sampling.The contents of the study included questionnaire survey,physical measurement and blood tests for fasting blood triglyceride (TG),total cholesterol (TC),low-density lipoprotein cholesterol (LDL-C),and high-density lipoprotein cholesterol (HDL-C) levels.Non-high-density lipoprotein cholesterol (non-HDL-C) level was calculated by TC level minus HDL-C level.Chi-square test and non-conditional logistic regression model were used to analyze the factors that contributed to dyslipidemia.Results:The dyslipidemia rate was 18.6％,and the abnormal rates of TG,TC,LDL-C,non-HDL-C and HDL-C were 6.8％,5.6％,2.3％,4.2％ and 8.6％,respectively.By chi-square test,the dyslipidemia rate in students with different ages,home locations,BMI groups,central obesity,time on watching TV or playing computer per day,and daily sleep time was statistically significant.Non-conditional logistic regression analysis showed that home location for the city (OR=1.332),overweight (OR=1.548),obesity (OR=2.201),central obesity (OR=1.695),watching TV or playing computer for more than 2 hours per day (OR=1.357),daily sleep time longer than 11 hours (OR=2.518) were the risk factors for dyslipidemia in students from the primary and middle schools.Conclusion:Nearly 1/5 primary and middle school students show dyslipidemia,which is associated with obesity and other bad behaviors.
