The Study Of Epidemiological Characteristics And Risk Factors Analysis On Dyslipidemia Of The Mid-aged And Elderly People In Dongxiang Nationality Of Gansu Province

ObjectiveTo investigate the abnormal incidence of serum cholesterol(TC),triglyceride(TG),high-density lipoprotein cholesterol(HDL-C),low-density lipoprotein cholesterol(LDL-C)among the mid-aged and elderly people of the Dongxiang minority area in Gansu province and provide the basis for the prevention and treatment of Cardiovascular disease such as hypertension and diabetes.MethodsQuestionnaire investigation and physical examination among 1000 people over 40 years of Dongxiang minority area in Gansu province were carried out by stratified random sampling method.The serum levels of total cholesterol(TC),triglyceride(TG),high-density lipoprotein cholesterol(HDL-C)and low-density lipoprotein cholesterol(LDL-C)were detected.The data were analyzed by t–test and analysis of regression(SPSS,Version 19.0).Results1.Lipid levels: All population TC,TG,HDL-C and LDL-C levels of all people respectively were(4.75± 1.21)mmol/L,(2.18 ± 1.45)mmol/L,(1.24± 0.31)mmol/L and(2.95 ± 0.86)mmol/L.Lipid levels of Dongxiang were(4.83 ± 1.35 respectively)mmol/L,(1.90± 0.17),(1mmol/L,(2.46 ± 0.64)mmol/L,(1.26 ± 0.29)mmol/L and(2.91 ± 0.78)mmol/L.lipid lev.23 ± 0.32)mmol/L and(2.98± 0.94)mmol/L.Lipid levels of Han were(4.77 ± 1.08)els of 40 to 59 years old middle-aged respectively were(4.75 ± 1.07)mmol/L,(2.01 ± 1.35)mmol/L,(1.26 ± 0.32)mmol/L and(2.89 ± 0.75)mmol/L.And lipid levels of elderly peopole aged over 60 respectively were(4.83 ± 1.32)mmol/L,(2.31±0.51)mmol/L,(1.22 ± 0.29)mmol/L and(2.98± 0.93)mmol/L.TC and LDL of Dongxiang were significantly higher than those of Han.Meanwhile,TC,TG and LDL of aged 60 or older were significantly higher than 40 to 59 years old and middle-aged people.2.The dyslipidemia rate: Dyslipidemia rate of Dongxiang was significantly higher than that of Han and the rate of abnormal TG and LDL had significant differences(P < 0.05).And dyslipidemia rate of old people over 60-year-old was higher than that of 40 to 59 years old and middle-aged people.At the same time,the rate of abnormal TG and LDL had significant differences(P < 0.05).3.Dyslipidemia rate of over 60-year-old in Dongxiang and Han among the different ethnic groups were significantly higher than those of 40 to 59 years old and middle-aged people.TG,HDL and LDL abnormal rate of elder people in Dongxiang significantly higher than those of the middle age and TG and HDL abnormal rate of elder people in Han were significantly higher than those of middle-aged people.4.In different age groups,dyslipidemia rate of the elder people aged over 60 in Dongxiang was significantly higher than that of the Han,especially TC,TG and LDL.And dyslipidemia rate of 40 to 59 years old and middle-aged in Dongxiang were significantly higher than those of the Han,especially TG and LDL.5.Fifteen factors of dyslipidemia factors were analyzed with single factor logistic regression analysis and then,statistically significant factors were analyzed again with multiariable logistic regression analysis.The final results showed that age and nationality were the risk factors of dyslipidemia.Conclusion1.Dyslipidemia rate of middle-aged and elder people in Dongxiang county of Gansu has higher level,of which dyslipidemia rate of elder people in Dongxiang is significantly higher than that of the Han and the elder people aged over 60 are significantly higher than those of 40 to 59 years old and middle-aged people.2.Dyslipidemia of residents in Dongxiang county of Gansu has the relation with the age,nationality,smoking,high blood pressure and BMI,of which the ethnic and age factor are a great impact factors.
