Abstract
Background Lifestyle factors are important modifiable influencing factors for cognitive decline and dementia. Understanding the status and influencing factors of community-dwelling middle-aged and elderly adults adhering to the lifestyles conducive to dementia risk reduction will be a basis for medical workers to formulate individualized interventions for primary prevention of dementia, yet there are still few related studies. Objective To understand the status and influencing factors of dementia risk reduction lifestyle in community-dwelling middle-aged and elderly adults. Methods Five hundred and six middle-aged and elderly adults (aged 45 years and older) who had received free health check-ups in a community health center were selected from five communities in Chongqing's Shapingba District by convenience sampling from January to October 2021. The self-designed general information questionnaire and the Dementia Risk Reduction Lifestyle Scale (DRRLS) were used to investigate. The level of DRRLS score in the participants was compare by sociodemographic characteristics. Ordinal and multinomial Logistic regression analysis was performed to identify the influencing factors of the levels of DRRLS scores. Results The average score of DRRLS was (88.00±13.27). The median scores of items in mental activity and brain-benefiting exercise were at a low level (≤2.00). The level of DRRLS score in the participants varied significantly by gender, age, personal monthly income and experience of receiving dementia-related health education (P<0.05). Ordinal and multinomial Logistic regression revealed that gender, educational level, personal monthly income and experience of receiving dementia-related health education were important influencing factors of the level of DRRLS score (P<0.05) . Conclusion In general, the lifestyles for dementia risk reduction were assessed at a moderate level in the community-dwelling middle-aged and elderly adults. In the primary prevention of dementia, the effects of mental activity and brain-benefiting exercise should be emphasized. Moreover, priority in community health management should be given to men, those with a low educational level or no previous experience of receiving dementia-related health education, and relevant health education and preventive interventions should be strengthened for them. All these efforts will urge these adults to adopt a lifestyle for dementia risk reduction and brain health promotion.
