Determining Recommendations for Preventing Elderly People from Cardiovascular Disease Complication Using Objective Distance

With increasing numbers of elderly people of the world's populations, Cardiovascular Disease (CVD) has become a critical health concern. It represents the main cause of death worldwide. Accordingly, preventing aged people from CVD has been extremely considered nowadays. The aim of this study is to determine proper recommendations to the elderly who have high risks of CVD complication for preventing themselves. Therefore, this paper applies the concept of an objective distance which is a measurement used as the indicator for recommendations. It defines the distance between the current status of the elderly people and objective level of each attribute for deriving the proper recommendations. Significantly, this distance provides the effective direction for their personal lifestyle adjustment. An experiment is performed in the context of hypertension, which is one of the main risk factors of CVDs. Data is gathered from 60 elderly people who are at the high risk of CVD in Chiang Rai, Thailand. A result of this experiment presents that the proposed objective distance can be efficiently employed for providing the appropriate recommendations to each elderly person. Also, they successfully modified their lifestyle behaviors for protecting themselves from CVDs, accounted for 90 percent accuracy.
