| Objective This study estimated the prevalence and influencing factors of the three main kinds of cardiovascular diseases (CVD), including hypertensive disease, stroke, and ischemic heart disease (IHD), and also evaluated the burden of disease of CVD in Tong Hai Country of Yunnan province.Methods The all-cuases-of death suvrey data in Tong Hai country from2006to2010were used, death diagnosis were grounded on "The cause of death medical certificate" offered by the hospitals that above the county level, all the causes of death based on ICD-10code. The population of Tong Hai country data comes from the local Bureau of Statistics. Due to lack of the three kinds of cardiovascular disease illness and disability material, this study adopts proportional probability sampling method (PPS sampling method), Tong Hai country consisted of9townships.Three villages was chosen from each township. In eaeh selected village, we obtained a name list of individuals aged≥18years from the village committee, and simple random sampling was used to select150individuals from each village. Information was obtained from a cross-sectional questionnaire survey. Disability adjusted life years (DALYs) was used as the measurement indicator of burden of disease. All statistical analysis use SPSS17.0software. Results We collected4070valid questionnaires, with a response rate was96.9%. In Tong Hai country of Yunnan province, the prevalence of hypertensive disease, stroke and ischemic heart disease were27.1%,2.13%,2.53%, respectively. Among males, the prevalence of hypertensive disease, stroke and ischemic heart disease was27.8%,2.71%and2.25%, whereas was26.4%,1.70%and2.74%for female; There was no significant difference of hypertensive disease, ischemic heart disease between males and females (P>0.05), but stroke was statistically significant (P<0.05), and males had higher prevalence than females. Three kinds of diseases, prevalence increased with age (P<0.05), older group people had higher obviously prevalence than yonger group people. Prevalence of hypertensive disease, the smoking group had higher than non-smokers group (P<0.05); Drinkers of ischemic heart disease and stroke prevalence were higher than non-drinkers (P<0.05); and the obesity group had higher prevalence of hypertensive disease than the non-obesity group (P<0.05); central obesity group had higher prevalence of hypertensive disease and ischemic heart disease than the non-central obesity group (P<0.05).The three main kinds of cardiovascular diseases by single factor and multi-factor Logistic regression to analyze:age, level of education, central obesity were major risk factor for hypertensive disease, and older age, lower educational level, central obesity had higher risk of hypertensive disease; Influence factors of stroke were sex, drinking, family history of stroke, and females, no drinking, no family history of stroke could reduce the risk of stroke disease; Influence factors of ischemic heart disease were age, obesity, salt, family history of hypertension, and older age, obesity could increase the risk of ischemic heart disease, low salt diet, with no family history of hypertension could reduce the risk of ischemic heart disease.From2006to2010, IHD was among the top ten leading cause of premature death, whereas stroke had been the top leading cause of YLL since2007. The YLL rate of stroke and IHD increased with year across these five years, whereas the YLL rate of hypertension disease fluctuated over time. The highest rates occurred among persons greater than60years, and YLL rate of three major CVD fluctuated over time among different age groups. Predominance of stroke in overall YLL rates in both sexes was noticed throughout the whole observed period. Females had higher YLL rate of hypertension disease and IHD than males. The DALYs/1000population of hypertensive disease was0.06, and females had higher DALYs rate than males (0.05vs.0.06).The DALYs/1000population of stroke was5.57, and males had higher DALYs rate than females (7.07vs.4.46).The DALYs/1000population of Ischaemic heart disease was10.1, and females had higher DALYs rate than males (8.98vs.10.9). In the three kinds of cardiovascular disease, ischemic heart disease is the most harmful to the health of people.Conclusion Cardiovascular diseases have become the main diseases for influencing Tong Hai country rural residents’ health. Ischemic heart disease is most serious for people’s health among three diseases, especially these kinds of people elder, obesity, high salt diet and family history of hypertension. So it is helpful to reduce the occurrence of cardiovascular disease by strengthening the health education of rural residents to stop smoking, drinking, since the childhood raining less salt, light diet, reducing salt intake. We should adop strategies prevention and treatment measures on the three major cardiovascular diseases. |
