Analysis On Relationship Of Body Mass Index,Waist Circumference,and Waist To Height Ratio With Blood Pressure,Blood Glucose,and Blood Lipids In Adults In Zhifu District Of Yantai

ObjectiveTo explore the prevalence of overweight,obesity,central obesity,hypertension,diabetes and dyslipidemia,and to gain changes from them in different populations and behavioral habits.Investigate the relationship of body mass index(BMI),waist circumference(WC),waist to height ratio(WHtR)with hypertension,diabetes and dyslipidemia,so as to provide scientific basis for chronic disease prevention and control in Zhifu.MethodsWith multi-stage stratified cluster sampling,residents aged 18 years and over were selected from 18 neighborhood committees of six street offices in Zhifu as subjects.Choose one resident group from each committee and 83 household therefrom.Finally,choose one person from each household according to KISH form.The investigation was performed with questionnaire by face-to-face interview(including smoking,'drinking and physical activity),physical examination(weight,waistline and blood pressure)and laboratory testing(blood glucose and blood lipids).To analyze the distribution of BMI,WC,WHtR,systolic blood pressure(SBP),diastolic blood pressure(DBP),fasting plasma glucose(FPG),total cholesterol(TC),triglycerides(TG),low-density lipoprotein cholesterol(LDL-C),and high-density lipoprotein cholesterol(HDL-C).To gain the prevalence of overweight,obesity,central obesity,hypertension,diabetes and dyslipidemia.The database was established by EPIDATA 3.1,and SPSS20.0 was employed for statistical analysis.Results(1)The BMI of adults in Zhifu District of Yantai was(25.91±3.88)kg/m2,WC was(87.53± 10.80)cm and WHtR was(0.53±0.06);male was higher than female in BMI and WC,but both were close to each other in WHtR.BMI,WC and WHtR increased with age but decreased as degree of education and household per capita income.They were also significantly different in smoking habits.There were differences between WC or WHtR in drinking habits.BMI was different in physical activity.(2)The prevalence of overweight,obesity and central obesity was 41.4%,26.37%,51.39%(measured by WC)and 88.04%(measured by WHtR),respectively.Overweight and central obesity prevalence in male was higher than female,however,there was no difference in obesity prevalence.Overweight and central obesity prevalence increased with age,but there was no difference in obesity prevalence of different age groups.Obesity and central obesity prevalence decreased as degree of education.Central obesity prevalence decreased firstly and increased again with household per capita income.It was the highest in adults who smoked before and drunk usually.(3)Adults in Zhifu District had SBP(128.50±19.97)mmHg,DBP(78.22±12.02)mmHg,FPG(6.14±1.75)mmol/L,TC(5.01±1.01)mmol/L,TG(1.64±1.54)mmol/L,LDL-C(2.86±0.73)mmol/L,HDL-C(1.29±0.30)mmol/L.SBP,DBP,FPG and TG of male was higher than female.However,female is higher than male in TC,LDL-C and HDL-C.SBP,DBP,FPG,TG,TC,and LDL-C increased with age but decreased as degree of education and household per capita income.SBP,DBP and FBG were the highest in groups who smoked before.SBP,DBP and TG were the highest in whom drunk usually.TG was the highest in groups who smoked usually.People who never smoked and had high-intensity physical activity had the highest level of HDL-C.(4)The prevalence of hypertension,diabetes and dyslipidemia was 36.20%,17.97%and 38.27%,respectively.They were higher in male than in female.The abnormal rates of SBP,DBP,IFG,TQ and HDL-C of male were higher than female,while TC and LDL-C lower than female.Prevalence became higher and higher with the increasing age,but it became lower and lower as degree of education.Hypertension;prevalence was different in different household per capita income.It was the highest in groups who smoked before and drunk usually,while diabetes prevalence in whom smoked before.Dyslipidemia prevalence was the highest in groups who smoked usually.(5)The prevalence of hypertension,diabetes and dyslipidemia of groups who had overweight,obesity and central obesity was higher than of normal groups.BMI,WC and WHtR were positively related with SBP,DBP,FBG,TC,TG and LDL-C,but negatively related with HDL-C.SBP was the most relevant.Adjust the age and gender factors,the correlation became weak,but doesn't change the direction.The risks of hypertension,diabetes,and dyslipidemia in overweight and obesity groups were 2.14,1.53,1.85 times and 4.75,2.80,3.36 times higher than in normal groups.The risk of central obesity was between overweight and obesity.Conclusion(1)The prevalence of overweight,obesity,central obesity,hypertension,diabetes and dyslipidemia in adults in Zhifu were higher than national level,also,the male was higher than female.Moreover,the prevalence was constantly increasing with the age.Degree of education,household per capita income and physical activity have a partial protective effect but smoking and drinking are dangerous factors.(2)Overweight,obesity and central obesity were important dangerous factors in causing hypertension,diabetes and dyslipidemia.The risk of them would rise with the increase of indicators of body fat(BMI,WC,WHtR).They could be index of screening to find groups with hypertension,diabetes and dyslipidemia in daily life.
