Study On The Cross-sectional Of 4 Chronic Noncommunicable Diseases Among People Aged 35～80 In Rural Areas Of Zhengyang County

ObjectiveThe chronic non-communicable disease includes obesity, hypertension, diabetes and dyslipidemia illness,etc. They are caused primarily by life style and environmental risk factors. Thus call primarily by life style illness. The data show that the hypertension prevalence is 18.8% above 18 years old in our country and the diabetes prevalence is 2.6% and the obesity prevalence is 7.1% and the dyslipidemia prevalence is 18.6% . Because chronic illness has the characteristics of the popular to the people crippling rate high and medical expense expensive. Thus this will create the tremendous burden to the society. The problem concernd by the entire society is how to prevent to the chronic disease. Therefore studing the chronic disease and the risk factor is significante to develop intervention measures, prevent chronic disease and improve the people life quality. This research explore the prevalence and the related risk factors of the main chronic non-communicable disease in partial middle-aged people and old people in Zhengyang County. The purpose is to provide the scientific basis for the NCD prevention in countryside.Objectives and methodsIndividuals aged 35～80 years were recruited by cluster sampling from two rural communities of Zhengyang county in 2007. Data of demographic characteristics, behavior risk factors and medical history were collected by standard questionnaire interview. Anthropometric measurements including weight, height, waist circumference, hip circumference and blood pressure were taken by standard techniques. We also examined laboratory measurements including total cholesterol, fasting glucose, high density lipoprotein cholesterol, triglycerides. T-test was usedto test the continuous variable (Data are shown as (x|-)±s) differences between the groups. Chi-square test was used to test the categorical variable (Data are shown as n (%) differences between the groups. Trend Chi-square test was used to test the trend of the prevalence with age. Standard test a = 0.05, bilateral test. The relationship between chronic diseases and related factors uses multi-factor Logistic regression analysis.ResultsThe distribution of the obesity and the abdominal obesity.The prevalent rates of obesity and abdominal obesity were 16.73% and 52.75% , respectively. The differences of the obesity prevalence were statistically significant for males and females (P<0.05).The differences of the abdominal obesity prevalance were statistically significant for different income levels(P <0.05).The distribution of the hypertension diabetes and dyslipidemia.The prevalences rates of the hypertension, diabetes and dyslipidemia were 29.06%, 12.21% and 54.95%, respectively. The differences of the hypertension prevalance were statistically significant for difference age, marry, education and income levels(P <0.05), respectively. The differences of the diabetes prevalance were statistically significant for difference age and income levels(P <0.05), respectively. The differences of the dyslipidemia prevalance were statistically significant for difference age, sex and income levels(P <0.05), respectively. The hypertension prevalance increased with age (trend test Z=6.34, P<0.0001). The prevalance of the diabetes and dyslipidemia increased with income levels (trend test Z=3.32, P=0.0004 and Z=3.52, P=0.0002).The prevalences of the main chronic non-communicable in the study population The prevalence rate were 48.96% ,12.45% ,7.81% and 0.85% for the participants who one main chronic non-communicable disease, two main chronic non-communicable diseases, three main chronic non-communicable diseases and four main chronic non-communicable diseases, respectively. The prevalance increased with age (trend test Z=2.43, P=0.0075) for the participants who with one main chronic non-communicable diseases. The prevalance increased with age and income levels (trend test Z=3.57, P=0.0002 and Z=3.14, P=0.0008) for the participants who with three main chronic non-communicable diseases. The relationship between chronic diseases and related factorsThe prevalences of the physical and occupational obesity has decreased. The prevalences of hypertension increased with age. The prevalences of hypertension increased who are smokers. The prevalance rates of the diabetes and dyslipidemia increased with age and income levels.ConclusionsThe prevalences of main chronic non-communicable in some rural areas of Zhengyang county were very high. The prevalence rate was 48.96% for the participants who one main chronic non-communicable. The chronic non-communicable was main factor that affected health.Sex ,age, education and income levels were possible related with the prevalences of the middle and old aged people.
