Study On The Relationship Between Waist Circumference And Blood Pressure In Children Aged 6-12 Years In Mojiang County,Yunnan Province

Objective:The influencing factors of hypertension in children and adolescents are numerous and complex,such as obesity,diet and genetic factors.The research on the blood pressure of children and adolescents in China is mainly focused on the han population in big cities,and there are few studies on remote areas and ethnic minorities.This survey mainly aims to understand the blood pressure situation and risk factors of minority children and adolescents in Mojiang county,Yunnan province.Methods:Adopt the method of cluster sampling survey,in school,extracting Mo Jiang County 12 primary school grade one students 2432 people,including 1343 boys and 1089 girls,measuring them basic data such as blood pressure,height,weight,waist circumference,and issuing questionnaires about children hypertension risk factors,including births,feeding conditions,smoking,drinking,diet,physical activity per week,sleep,past history,parents’ blood pressure,parents’ education,and family population and income,etc.Spearman rank correlation analysis and ordered logistics regression were used to analyze the relationship between blood pressure and various measurement indexes.Results:The detection rate of hypertension in children was 9.0%,including 1.27%for severe hypertension,9.5%for male,1.3%for severe hypertension,8.4%for female and 1.2%for severe hypertension.The overall detection rate of overweight in children was 9.8%,and the detection rate of obesity was 4.9%.The detection rates of overweight and obesity in boys were 11.1%and 4.8%,in girl were 8.3%and 5.0%,respectively.The overall detection rate of abdominal obesity was 10.1%,10.8%for boys and 9.3%for girls.There was no significant difference in the detection rates of overweight,obesity and abdominal obesity between men and women(P>0.05).Spearman rank correlation analysis:age,height,weight,waist circumference and BMI were positively correlated with systolic blood pressure and diastolic blood pressure,while gender was not significantly correlated with blood pressure.Logistics regression results suggested that waist circumference is a risk factor affecting the prevalence of hypertension.Conclusion:As an important indicator of abdominal obesity,waist circumference of children has a good correlation with blood pressure,which is of great significance in predicting hypertension in children.
