The Relationship Between BMI?Diet And Hypertension And Coronary Heart Disease In Middle And Old Aged People

Research objectiveBy using the method of questionnaire and experimental method to understand the indicators in the elderly population living habits,physical characteristics,analysis of the epidemiological characteristics of hypertension and coronary heart disease in the elderly population,the prevalence rate of BMI,the relationship between dietary factors and hypertension,coronary heart disease,to detect whether there is a dose-response relationship between them,in order to realize the early prevention and treatment of hypertension,to provide a clinical basis for coronary heart disease.Research methodFrom June 2016 to September 2016,a cross-sectional survey was conducted among 3000 urban residents in Jinhua city of Zhejiang province,Huainan city of Anhui province,Jiyuan city of Henan Province,and Yangxin city of Hubei province.The contents of the study include the basic information of the subjects,the way of life behavior and the physical condition.The lifestyle behaviors include smoking,eating,drinking,exercise and sedentary.The state of the body mainly includes hypertension,coronary heart disease and so on.45 years and above in the elderly population as the research object,using general descriptive study,different BMI diet and hypertension,coronary heart disease,by Logistic regression analysis.18.5kg/m2<BMI ? 24kg/m2.Salt correction group<4.17g,BMI group and other calculated values of OR and 95%CI salt group.According to the dose-response model of each BMI,the median salt interval for the dose value,the exposure interval number and the total number of cases,the value of OR and 95%CI further statistics and Research on the BMI and the amount of salt increased relationship with hypertension and coronary heart disease.Research results1.2796 people in the survey,there are 1281 men,women,there are 1515 people.The prevalence rate of hypertension was 33.4%,and the prevalence rate of coronary heart disease was 27.4%.In the male obesity group and the overweight group,the prevalence rates of hypertension and coronary heart disease were 62.3%,66.7%and 34.2%,66.7%respectively.In female obesity group and overweight group,the prevalence rates of hypertension and coronary heart disease were 59.9%,77.4%and 43.4%,45.2%respectively.2.Logistic regression analysis showed that compared with the normal group,the risk of hypertension in the obese group,the obese group and the obese group were OR 1.75(95%CI:1.47-2.08,P<0.001),and 4.71(95%CI:3.57-6.23,P<0.001),9.41(95%CI:4.39-20.16,P<0.001),and overweight group,obesity group,overweight group of coronary heart disease risk of OR were 1.22(95%CI:1.02-1.46,P<0.05),2.03(95%CI:1.54-2.68,P<0.001),2.95(95%CI:1.53-5.69,P<0.01).With the increase of BMI hypertension and coronary heart disease risk also increased in BMI with hypertension and coronary heart disease between the dose-response relationship of BMI per 5kg/m2,the prevalence of hypertension increases the risk of 10%,OR1.10(95%CI:1.06-1.14,P<0.0001),coronary heart disease risk increased by 6%,OR 1.06(95%CI:1.03-1.09,P<0.0001).3.The prevalence of hypertension was highest in group diet respectively 11.11 g<salt group(62.2%),21.13g<red meat ? 37.50g group(41.1%),14<egg group(37.5%),The highest prevalence of coronary heart disease group diet respectively in 11.11g<salt group(25.9%),red meat ?21.13g group(31.3%),3<egg ? 7(23.9%).4.Logistic regression results show that compared with the salt less than 4.17g group,4.17g<salt?5g,5g<salt ? 8.33g,8.33g<salt?11.11g,11.11g<salt group,the risk of suffering from hypertension OR were 1.50(95%CI:0.87-2.58,P<0.05),1.61(95%CI:1.07-2.20,P<0.01),3.38(95%CI:,2.29-4.99,P<0.001),7.49(95%CI:4.60-12.21,P<0.001).With the salt intake increased the risk of hypertension was increased,there was a dose-response relationship between daily salt intake and hypertension:daily salt intake increased the risk of hypertension in 2G,increased by 35%,OR1.35(95%CI:1.26-1.44,P<0.0001),while the daily salt intake and coronary heart disease there is no dose-response relationship(P=0.911).Conclusion:1.The prevalence of hypertension and coronary heart disease increased with the increase of BMI.The prevalence rate of hypertension in male overweight group was lower than that in female,and the prevalence rate of coronary heart disease was higher than that of female.2.Obesity is the main risk factor for hypertension and coronary heart disease.There was a dose-response relationship between BMI and hypertension,coronary heart disease,and the prevalence of hypertension and coronary heart disease increased significantly with the increase of BMI.3.Large intake of eggs can increase the risk of high blood pressure.4.The daily intake of salt more than 5g will be a serious threat to the risk of high blood pressure,daily salt intake and the prevalence of hypertension,there is a dose-response relationship,with the increase in the incidence of hypertension increased the proportion of salt.
