Objective

To analyze the prevalence of three cardiovascular diseases categories (hypertension, coronary heart disease and stroke), and their impact on activity of daily living (ADL) among the elderly in rural Dayao County of Yunnan Province.

Methods

A multi-stage stratified random sampling method was employed in selecting 1 382 rural residents≥60 years from Dayao County for questionnaire survey and physical examination.Multivariate logistic regression models were applied to analyze the association between the prevalence of hypertension, coronary heart disease (CHD), stroke and ADL.

Results

Among the interviewed respondents, the prevalence of hypertension, CHD, stroke, and the impaired rate of physical activity of daily life (PADL), instrumental activity of daily life (IADL) and ADL was 66.2%, 14.6%, 5.9%, 6.6%, 36.5%, and 37.2%, respectively. The prevalence of hypertension, CHD, and stroke and impaired rate of PADL, IADL, and ADL increased with age (, P<0.05). Females had higher prevalence of hypertension, impaired rate of IADL and ADL than males (χ2=7.319, χ2=56.112, χ2=52.510, P<0.05). Older adults with lower level of education had lower prevalence of CHD (χ2=3.930, P<0.05) while they had higher impaired rate of PADL, IADL, and ADL than their counterparts (χ2=7.438, χ2=99.487, χ2=101.057, P<0.001). Similarly, older adults with lower household incomes had lower prevalence of CHD and stroke (χ2=6.442,χ2=4.250, P<0.05) while they had higher impaired rate of IADL and ADL (χ2=6.517, χ2=4.934, P<0.05) than their counterparts. The outcomes of the analysis utilizing multivariate logistic regression suggested that hypertensive older adults (OR=1.760, 95% CI: 1.037-2.985) and older adults who suffered from stroke (OR=3.692, 95% CI:1.989-6.856) were more likely to have higher impaired rate of PADL than their counterparts.

Conclusion

There is a relatively high prevalence of three types of cardiovascular diseases while low level of daily living activity among older adults in Dayao County. Reducing the prevalence of hypertension and stroke would be helpful to alleviate the impaired rate of activity of daily living.
