Analysis Of Prevalence And Influencing Factors Of Hypertension And Prehypertension In Primary And Middle School Students In Jilin Province

Objective:To investigate the prevalence of hypertension and prehypertension in primary and middle school students in Jilin Province from 2016 to 2017,to analyze the factors that cause the increase in blood pressure levels,in order to provide scientific basis for the development of prevention and treatment measures for hypertension and prehypertension in primary and secondary school students.Methods:In 2016-2017,a total of six monitoring points were selected in Jilin Province,and multi-stage stratified random sampling was used to conduct the survey.The number of primary and secondary school students effectively surveyed was 1,642.Considering the irreversibility of the disease,the number of patients with hypertension(n=287)was removed in the pre-hypertension detection and factor analysis.The survey mainly includes:questionnaire survey(student basic information,student personal nutrition and health status,etc.),physical measurement(height,weight,waist circumference,blood pressure,etc.)and laboratory tests(serum vitamin A,urinary iodine,urine sodium,blood uric acid,etc.)).The data were analyzed by IBM SPSS24.0 statistical software.The usage rate or composition ratio of the count data was used.The chi-square test was used for comparison between groups,and the two-class logistic regression analysis method was used for the analysis of influencing factors.Result:1.The effective number of primary and secondary school students in this effective survey was 1,642,which including 287 hypertension patients,the prevalence rate was 17.5%;the number of pre-hypertension patients was 201,and the prevalence rates was 14.8%.The pre-hypertension prevalence rates of boys and girls were 13.8%and 15.9%,respectively.The prevalence of hypertension in boys and girls was 15.2%and 19.8%,respectively.2.Single factor analysis results showed that there were statistically significant differences in the prevalence rates of the prehypertension among primary and middle school students of different primary caregiver(X~2=29.706),drinking water source(X~2=10.336),staple food frequency(X~2=25.848),meat frequency(X~2=16.466),waist circumference(X~2=26.792),weight(X~2=24.977),hyperuricemia(X~2=11.245)and family history of hypertension(X~2=136.096).There were significantly significant differences in the prevalence rates of the hypertension among primary and middle school students of different gender(X~2=6.081),age(=16.342),alcohol consumption(=33.230),sleep time(=10.794),snoring(=13.786),weight control measures(=17.295),blood pressure time(=20.469),waist circumference(=101.598),weight(X~2=119.999),hyperuricemia(X~2=29.567),family history of hypertension(X~2=138.208),family history of dyslipidemia(X~2=7.101),etc.there were statistically significant difference in the prevalence of hypertension among primary and middle school students(P<0.05).3.The results of binary logistic regression analysis showed that the main caregivers were other(OR=3.350,P<0.001),almost no staple food(OR=7.353,P<0.001),high waist circumference(OR=2.240,P<0.001),A family history of hypertension(OR=6.251,P<0.001)were risk factors for pre-hypertension.4.The results of the two-class logistic regression analysis showed that males(OR=0.719,P=0.026)weight control measures(OR=0.632,P=0.007),blood pressure within one month(OR=0.253,P=0.001),and blood pressure within 6 months(OR=0.456,P=0.031),blood pressure over 6 months(OR=0.290,P<0.001)is a protective factor for hypertension;drinking within 30 days(OR=2.583,P<0.001),overweight(OR=2.285,P<0.001),obesity(OR=4.088,P<0.001),marginal deficiency and deficiency of vitamin A(OR=1.900,P=0.008),family of hypertension History(OR=5.050,P<0.001)and a family history of dyslipidemia(OR=1.846,P<0.001)were risk factors for hypertension.Conclusions:1.The blood pressure status of primary and middle school students in Jilin Province surveyed from 2016 to 2017 was analyzed.The pre-hypertension detection rate and hypertension prevalence rate were 14.8%and 17.5%,respectively,which were at a high levesl.2.Among the hypertensive patients of primary and secondary school students,the number of people with hypertension is only 2,and the awareness rate is 0.69%,which is at a low levels.3.Among the primary and secondary school students surveyed,the main caregivers were non-parents,almost no staple food,high waist circumference,and family history of hypertension were risk factors for pre-hypertension.4.Among the students in the survey,drinking alcohol within 30days,Overweight,obesity,marginal deficiency and deficiency of vitamin A,family history of hypertension,and family history of dyslipidemia are risk factors for hypertension.
