| ObjectiveTo investigate the characteristics in prevalence of prehypertension,hypertension and the related factors among 18 years of Hunan province from 2007 to 2015,to provide a scientific basis for preventing and treating cardiovascular disease.MethodsData were collected from the Databanks of China Non-communicable and Chronic Disease Risk Factor Surveillance.in 2007,2010,2013 and 2015,respectively.The multi-stage stratified clustering sampling method was conducted in the survey.The study was conducted by questionnaire,physical measurement and laboratory examinations.This study selected residents aged 18 in each survey year as the research object.Calculate the prevalence of prehypertension and hypertension prevalence with different demographic characteristics,and the hypertension awareness rate,treatment rate,and control rate.Analyzing the possible risk factors of hypertension.Standardized rate were calculated with 2010 China's sixth national census Hunan's population.The used software was SAS9.4,?2 test and Cochran-Armitage trend test were used to analyze the trends.Multivariate logistic regression was used to analyze the risk factors of hypertension.Results1.The prevalence of prehypertension in Hunan from 2007 to 2015 was in decreasing trend,and the standardized prevalence of prehypertension from 2007 to 2015 were 40.38% to 36.30%,with significant difference(P<0.01).The prevalence of prehypertension in each survey year were all decreased with age(P<0.01).The highest rate of prehypertension in female was 18~ aged,while male was 40~ aged.The standardized prevalence of prehypertension in male and female who were in urban areas were no significant difference trend(P>0.05)in 8 years.In rural areas,the standardized prevalence of prehypertension in male was in decreasing trend(P<0.05).The standardized prevalence of prehypertension of male in urban and rural areas were higher than female in each survey year(P<0.05,P<0.01).There was no significant difference in the standardized rate of prehypertension in male between urban and rural areas during each survey years(P>0.05),and the female's result was the same as that of male(P>0.05).2.The prevalence of hypertension in Hunan from 2007 to 2015 was in increasing trend,with significant difference(P<0.01).The standardized prevalence of hypertension from 2007 to 2015 were 27.32% to 30.98%,with no significant difference trend(P>0.05).The prevalence of hypertension in each survey year were all increased with age(P<0.05).The prevalence of hypertension in male who in 18~ aged and 40~ aged were increasing,but 18~ aged female was in descending trend.They were all with significant difference(P<0.05,P<0.01).In rural areas,the standardized prevalence of hypertension in male was in increasing trend,with significant difference(P<0.05).During each survey years,the prevalence of standardized hypertension in urban male was higher than urban female in the other years(P<0.05,P<0.01),except 2007.In 2007 and 2010,the prevalence of standardized hypertension of male in urban was significantly higher than that in rural(P<0.05,P<0.01).In 2007 and 2015,the prevalence of standardized hypertension in female in urban was lower than that in rural.They were all with significant difference(P<0.05,P<0.01).3.The awareness rate,treatment rate and control prevalence of hypertension in Hunan province showed an increasing trend,but there was no obvious change trend after standardization(P>0.05).In ach survey years,the awareness rate and treatment rate of hypertension increased with age(P<0.05).In the 8 years,there was no significant difference in the awareness,treatment and control rate of male after standardization(P>0.05).The standardization rate of hypertension control showed an increased trend on female(P<0.05).The standardization awareness and control rate in urban showed a decreased trend,which was statistically significant(P<0.05),while the standardization rate of control in rural showed an increased trend(P<0.01).In anther survey years except 2007,the male's awareness and treatment prevalence of hypertension were lower than female(P<0.05).In 2015,male's standardization rate of control were lower than female(P<0.05).In 2007 and 2013,the standardization awareness prevalence in urban was higher than rural(P<0.01).And the standardization prevalence of treatment and control as higher than rural in each years.They were all with significant difference(P<0.05,P<0.01)..4.The multivariate analysis of logistic regression showed that the risk factors of hypertension were increased age,living alone,drinking,abdominal obesity,hyperlipidemia,hyperuricacidemia,family history of hypertension,and high lever of BMI.The higher education level was the protective factor.Conclusion1.In 2007-2015,the prevalence of adult prehypertension in Hunan Province showed a decreasing trend.The highest prevalence rate of prehypertension in men was in the youth,while female was in the middle-age.Health education should be carried out for young men and middleaged women to prevent primary hypertension.2.The standardized prevalence of hypertension in Hunan Province in 2007-2015 was relatively stable.But elderly group and male in rural resident with hypertension were on an increased trend.The prevalence of hypertension in male were higher than female in urban.It shows that the elderly,rural and male groups are the key targets for prevention and control of hypertension.3.The prevalence of awareness,treatment of hypertension in female were higher than male in Hunan Province in 2007-2015.Although the prevalence of awareness and control of hypertension in urban declined slightly,they were still higher than rural.It's suggested that male,urban and rural resident all need to strengthen screening of hypertension in order to find high blood pressure earlier.4.High cultural level,old age,living alone,drinking,abdominal obesity,hyperlipidemia,hyperuricacidemia,family history of hypertension and high level of BMI,are the main influencing factors of hypertension in Hunan Province. |
