Prevalence of cardiovascular metabolic risk factors among 12-18 years old adolescents in Yinchuan City from 2017 to 2019

Abstract

To understand the prevalence of cardiovascular metabolic risk factors among 12-18 years old children and adolescents in Yinchuan City. A survey was conducted among 12-18 years old middle school students in Yinchuan from September 2017 to September 2019. A total of 1956 subjects were collected by using convenient sampling method, with an average age of(14. 4±1. 4) years. Boys and girls accounted for 52. 1% and 47. 9%, respectively, The Han and Hui nationalities accounted for 77. 7% and 16. 4%, respectively. Basic data such as age and gender were collected through questionnaire survey, and physical examination was used to measure height, weight, waist circumference and blood pressure. Fasting blood glucose, triglyceride(TG), total cholesterol(TC), high density lipoprotein cholesterol(HDL-C) and low density lipoprotein cholesterol(LDL-C) were measured by laboratory blood pressure biochemistry. The detection rates of obesity, abdominal obesity, hypertension, hyperglycemia, high TG, high LDL-C, low HDL-C, high LDL-C and dyslipidemia among 12-and 18-year-olds in Yinchuan City were 8. 3%, 17. 9%, 12. 4%, 1. 9%, 13. 2%, 2. 4%, 18. 6%, 1. 9% and 30. 1%, respectively. The detection rates of obesity, hyperglycemia, low HDL-C, high TG and dyslipidemia in boys were significantly higher than those in girls. Obesity, abdominal obesity and hypertension in 12-15-year-old group were higher than those in 16-18-year-old group, and the detection rates of high TC, low HDL-C, high LDL-C and dyslipidemia were lower than those in 16-18-year-old group(P& lt; 0. 05). The prevalence of cardiovascular risk factors in different age groups of boys and girls were compared. The detection rates of obesity, abdominal obesity and hypertension in the 12-15 age group were higher than those in the 16-18 age group, while the rates of high TG, low HDL-C, high LDL-C and dyslipidemia were higher in the 12-15 age group, but these differences were only significant in boys. Among girls, the detection rate of high TC and high LDL-C was higher in the age group of 12 to 15 years old(P& lt; 0. 05). The detection rate of metabolic syndrome in 12-18-year-old adolescents was 7. 9%. The detection rate of metabolic syndrome in boys(10. 1%) was higher than that in girls(5. 5%). The detection rates of metabolic syndrome in 12-15 years old and 16-18 years old were 9. 1% and 4. 9% respectively, and the differences were statistically significant(P& lt; 0. 05). The prevalence of cardiovascular metabolic risk factors in 12-18 years old adolescents in Yinchuan City is at a high level, boys are higher than girls, and the prevalence of obesity, abdominal obesity and hypertension are higher in 12-15 years old group. Dyslipidemia varies greatly in different gender and age groups.
