Health beliefs model to explore older adults' dementia prevention and health promotion from 2021 to 2022 in Taiwan: A cross-sectional survey study.

One person suffers from dementia every 3 seconds globally. Thirteen older adults aged 65 and older will have dementia, and 1 in 5 older adults over the age of 80 years will have dementia in Taiwan. Older adults should be equipped with demonstrated health beliefs regarding dementia prevention and health promotion about Ascertain Dementia 8-item Questionnaire (AD8), cues to action, health beliefs, self-efficacy, and behavioral intention in daily life. The purpose of this study was to survey older adults' demographic background, AD8, cues to action, health beliefs, self-efficacy, and behavioral intention for dementia prevention and health promotion. A cross-sectional survey design was used. Convenience sampling was performed. A total of 330 older adults participated in the study. The questionnaire used in this study included questions on older adults' demographic background, AD8, cues to action, health beliefs, self-efficacy, and behavioral intention. The researcher collected complete data by receiving the sampling on paper or by interview from October 8, 2021, to February 12, 2022. The SPSS 23.0 statistical package was employed for quantitative analysis. Data analysis included frequency, percentage, mean, standard deviation (SD), Spearman's rho correlation, and simple regression analysis. The findings showed that older adults had the following mean scores on health beliefs (perceived susceptibility 13.45 ± SD 2.34, perceived severity 13.54 ± SD 2.69, perceived benefits 16.57 ± SD 2.84, perceived barriers 8.20 ± SD 3.69), self-efficacy 16.96 ± SD3.52, and behavioral intention 19.56 ± SD 3.51. Older adults' demographic background, perceived susceptibility, perceived severity, perceived benefits, perceived barriers, and self-efficacy explained 56.1% of the variance in behavioral intention. The conclusions of the study indicated that older adults' demographic background, AD8, cues to action, health beliefs, self-efficacy, and behavioral intention constituted the main factors for effective dementia prevention and health promotion. In the future, the research team will continue to explore older adults' dementia prevention and develop many strategies on health promotion, as well as slowing the aging brain process.
