Factors Influencing the Dementia-Preventive Behaviors among Middle-Aged Persons with Chronic Diseases in Korea.

The purpose of this study was to investigate the influence of dementia literacy, internal health locus of control, and fear of dementia on dementia-preventive behaviors among middle-aged people with chronic diseases. The participants were middle-aged individuals with chronic diseases who had been taking medications for at least three months, recruited using convenience sampling. A total of 123 participants were recruited between 13 and 31 March 2020, using self-reported questionnaires. Data were then analyzed through independent t-test, one-way ANOVA, Pearson's correlation coefficient, and multiple linear regression using the SPSS/WIN 25.0. The results showed that health condition perceived as healthy and dementia literacy were the leading factors influencing dementia-preventive behaviors. These variables showed a 16% explanatory power for dementia-preventive behaviors. Therefore, when the participants' perceived health condition was healthy and the dementia literacy score was higher, the level of dementia-preventive behaviors was also higher. It is necessary to develop educational programs to increase dementia literacy as a major variable in dementia-preventive behaviors, and further research on its efficacy should be conducted. When providing dementia-preventive education programs to middle-aged people who have been exposed to chronic diseases, it is necessary to consider their level of perceived health condition and dementia literacy.
