| Objective:This study examined the prevalence rate and aggregation of cardiovascular risk factors in Yu Long county of Yunnan province based on a cross-sectional investigation conducted in 2014 among Naxi people. Exploring the relationship between exposure rate and clustering of cardiovascular risk factors and individual socioeconomic status. In order to provide evidence for the prevention and control of cardiovascular diseases, and promoting the formation of the guidelines which for prevention and treatment of cardiovascular disease among Naxi residents.Methods:Inventory survey was employed in this study, Multistage sampling method was used to select a representative sample of Naxi residents aged 35 and from 16 townships of Yu Long County conducted a questionnaire survey and physical examination. In site survey, the basic demographic data and the main cardiovascular risk factors were collected. Measurement of physical examination including height, weight, waist circumference, hip circumference, blood pressure and blood glucose. Principal component analysis was used to construct the socioeconomic comprehensive score. Composition of cardiovascular disease risk factors were analyzed by chi-square test. Logistic regression analysis was used to analyze the influence of socioeconomic factors on prevalence rate and aggregation of cardiovascular risk factors.Results:In this study, a total of 1450 people were investigated,1402 valid questionnaires were obtained, and the response rate was 96.69%. The overall prevalence rates or exposure level of overweight, obesity, central obesity, hypertension, diabetes, smoking, drinking and cardiovascular disease, prevalence rates of family history, high salt diet, passive smoking, life stress, depression, lack of physical activity were 26.0%,8.9%,39.5%,32.9%,24.5%,10.34%,27.4,21.8%, 9.3%,5.2%,32.2%,26.2% and 4.1%, respectively. Different groups(gender, age, educational level, income level, marital status, head of the household, housing conditions, accessibility of medical institutions, and socioeconomic status) are exposed to different cardiovascular disease risk factors significantly (all p<0.05).93.4% of Naxi residents were exposed to one or more CVD risk factor. Different gender, age, householder state, housing situation, social and economic conditions differed distribution of CVD risk factors among Naxi people (p<0.05).The multivariate logistic regression analysis shows that, among Naxi people, those who was head of the household have possibility of obesity prevalence 2.577 times higher than that of those was non householder, and those who with good housing situation are 1.415 times more likely have obesity prevalence than those with poor housing situation, those who with high education level are 0.754 times more likely have obesity prevalence than that of those with lower education level. Those who were married or lived together have possibility of hypertension prevalence 0.427 times higher than that of those were unmarried or divorced, and those who with high education level have have possibility of hypertension prevalence 0.696 times higher than that of those with lower education level. Those who was head of the household have possibility of smoking 0.101 times higher than that of those was non householder, those who with high education level are 1.633 times more likely have smoking prevalence than that of those with lower education level.Those who was head of the household have possibility of drinking 0.157 times higher than that of those was non householder, those who with high education level are 1.599 times more likely have drinking prevalence than that of those with lower education level, those who with good housing situation are 1.356 times more likely have drinking prevalence than those with poor housing situation. Those who was head of the household have possibility of passive smoking 2.880 times higher than that of those was non householder, hose who with high education level are 0.751 times more likely have passive smoking prevalence than that of those with lower education level, those who with good housing situation are 1.451 times more likely have passive smoking prevalence than those with poor housing situation. Those who with high income level are 0.698 times more likely have life pressures than those with low income level. Those who was head of the household have possibility of depression 1.848 times higher than that of those was non householder. Those who were married or lived together have possibility of physical inactivity 0.490 times higher than that of those were unmarried or divorced, those who with good housing situation are 2.104 times more likely have physical inactivity than those with poor housing situation. Householder, people with poor housing conditions and poor accessibility of medical institutions were associated with higher possibility of CVD risk factors clustering.Conclusion:The prevalence rate and aggregation of cardiovascular risk factors among Naxi residents in Yu Long County is not optimistic. Householder, educational level, housing situation, marital status and income level were the socioeconomic impact factors on prevalence rate of cardiovascular disease risk factors among Naxi residents, householder, housing conditions and accessibility of medical institutions were the socioeconomic impact determinants on aggregation of cardiovascular risk factors among Naxi residents. More effective attention and intervention on exposure rate of cardiovascular disease risk factors are required for the householder, people who with good housing situation, low education level, low education level, and those who were unmarried or divorced. More effective attention and intervention on aggregation of cardiovascular risk factors should also put more focus on householder, people who with poor housing situation and poor accessibility of medical institutions. Reducing the adverse effects of socioeconomic status on the exposure rate and aggregation of cardiovascular risk factors among Naxi residents. |
