Cardiovascular disease(CVD)
Cardiovascular disease is caused by disorders of the heart and blood
vessels, and includes coronary heart disease (heart attacks),
cerebrovascular disease (stroke), raised blood pressure
(hypertension), peripheral artery disease, rheumatic heart disease,
congenital heart disease and heart failure.

The major risk factors of CVD
There are more than 300 known CVD risk factors. The major causes of
cardiovascular disease are tobacco use, physical inactivity, an
unhealthy diet and harmful use of alcohol.


Cardiovascular
disease has
become the
leading cause of
death in the world
80% of the CVD
occurred in low and middleincome countries
Economic burden

Aims

To analyze socioeconomic influencing determinants of
CVD risk factors among Naxi ethnic minority in Yulong
county of Yunnan province.


Three

Methods

1. Stratified random sampling was used to select a
representative sample of 1402 Naxi ethnic minority
aged 35 and over from Yulong county.
2. Information was obtained from a cross-sectional

questionnaire and health examination survey.
3.Descriptive statistical analysis were used for the
basic situation of people surveyed and the
constitutents of different risk factors .
4. Chi-Square was undertaken for exploring the
association between clustering of CVD risk factors and
socioeconomic position.

Measure of socioeconomic status

Socioeconomic status was measured by six main
indicators: householder; level of education; tap water
in the home; toilet in the home; housing situation;
per-capita income.

Conclusion

The findings indicate a
higher level of clustering of
CVD risk factors among Naxi
ethnic minority people in
Yunnan province.

1. Popularize the health
education
2. Improve economic
performance
3. Enhancing public education
level

Comprehensive prevention and control of CVD should more
foucs on male Naxi residents.

Future prevention and intervention strategies of CVD
should more focus on non head of household, individuals with
low level of education and low socioeconomic position.
