China is facing the great pressure of aging population, and dementia accounts for a large number of people. Cognitive function assessment can directly and easily measure the cognitive function status of the elderly. However, cognitive function assessment is not popular among the public, and few people even take the initiative to seek medical treatment for cognitive decline. Telephone cognitive assessment is an important assessment method, but there is a lack of telephone cognitive assessment tools in our country, especially for healthy elderly people in the community. At the same time, the development of simple and feasible cognitive assessment tools is very important to maintain the cognitive health of the elderly in China. Based on cognitive assessment, cognitive health-related factors can be explored in order to better carry out preventive measures.
According to the above questions, two sub-studies are designed. Study 1 Develops and validates a telephone-based cognitive function measurement tool that provides a brief but comprehensive assessment of cognitive function in healthy Chinese older adults. In the second study, the relationship between lifestyle factors and cognitive function in the context of healthy aging was explored to provide evidence for improving cognitive function in the elderly. The specific research methods and results are as follows.
Study 1: Based on the theory of cognitive aging and literature review, the sensitive dimensions and tasks of cognitive aging were selected, and the tasks were localized to form a telephone cognitive assessment scale with five dimensions and five tasks. A total of 68 normal elderly subjects were recruited. Cognitive function was tested over the phone, followed by an in-person test and the Montreal Cognitive Assessment (MoCA) two weeks later. Pearson correlation r = 0.72 (p < 0.001); There was moderate to strong correlation between telephone cognitive sub-test and face-to-face assessment sub-test. The comprehensive telephone cognitive score was correlated with the total MoCA score r = 0.44 (p < 0.001).
Study 2: 112 older adults were recruited. The cognitive function of the elderly was assessed by telephone cognitive assessment tool, and the demographic situation and lifestyle of the elderly were assessed by questionnaire survey. One-way ANOVA and multiple linear regression analysis were used to explore the relationship between life style and cognitive function. The higher education level and the higher intelligence and social activities (β = 0.186, p = 0.045) tended to have better performance in word pair association tasks. The elderly with higher life satisfaction (β = -0.225, p = 0.021) had lower scores on fluency tasks. The cognitive comprehensive score of the elderly with lower education was lower.
In conclusion, the telephone cognitive assessment tool developed in this study has similar effects to traditional face-to-face tests. The reliability and validity of the scale are good, and it can be used for comprehensive assessment of cognitive function of healthy elderly people in community. Higher education, more participation in intellectual and social activities may be protective factors for cognitive function in the elderly, and higher life satisfaction may be associated with lower scores on class fluency tasks.
