摘要
背景关于短期、低强度、多领域痴呆风险降低干预措施对老年人的影响鲜为人知。目标研究低强度、多领域生活方式干预措施对澳大利亚老年人痴呆风险和痴呆知识的有效性和可行性。干预措施为期3个月的降低痴呆风险计划 "大脑训练营"(BRAIN BOOTCAMP),包括教育、个性化风险信息、更健康选择的身体提示以及目标设定和规划,针对老年人饮食、运动、认知活动和社交互动这四个可改变的风险因素。痴呆症认知度是通过一份源自荷兰和英国调查的改良问卷进行测量的,包括知识、降低风险和意识等方面。我们使用配对 t 检验来比较计划实施前后的痴呆症风险得分和痴呆症知识水平。研究还进行了多变量回归,以确定与 LIBRA 指数变化相关的社会人口和心理因素。完成计划的参与者痴呆症风险评分降低(Cohen's d=0.59,p<0.001),痴呆症知识和意识提高(Cohen's d=0.64,p<0.001),改变生活方式行为的动机增强(Cohen's d=0.25-0.52,p<0.016)。结论提高老年人的积极性和知识水平可能有助于改变生活方式以降低痴呆风险。结论提高老年人的积极性和知识水平可能有助于改变他们的生活方式,降低痴呆症的风险。然而,项目中的自然减员仍然是一个挑战,这表明需要制定策略来提高参与者的参与度和对此类干预的保留率。
A Pilot Study of BRAIN BOOTCAMP, a Low-Intensity Intervention on Diet, Exercise, Cognitive Activity, and Social Interaction to Improve Older Adults’ Dementia Risk Scores
Background
Little is known about the impact of short, low-intensity multidomain dementia risk reduction interventions in older adults.
Objectives
To examine the effectiveness and feasibility of a low-intensity multidomain lifestyle intervention on dementia risk and dementia literacy in Australian older adults.
Design
Single-group pre-post design.
Setting
Community-dwelling.
Participants
A total of 853 older Australians (Mean age=73.3 years, SD=6.1) recruited from the community.
Intervention
A 3-month dementia risk reduction program, BRAIN BOOTCAMP, including education, personalised risk information, physical cues for healthier choices and goal setting and planning to target four modifiable risk factors of diet, exercise, cognitive activity and social interaction in older adults.
Measurements
The ‘LIfestyle for BRAin health’ (LIBRA) index was used to assess participants’ modifiable dementia risk based on 12 factors, with higher scores indicating greater risk. Dementia literacy was measured using a modified questionnaire derived from Dutch and British surveys, encompassing knowledge, risk reduction, and awareness aspects. Paired t-tests were used to compare dementia risk scores and dementia literacy before and after the program. Multivariate regressions were performed to identify sociodemographic and psychological factors associated with change in the LIBRA index.
Results
Program attrition was high (58.3%). Participants who completed the program had decreased dementia risk scores (Cohen’s d=0.59, p<0.001), increased dementia literacy and awareness (Cohen’s d=0.64, p<0.001) and increased motivation to change lifestyle behaviors (Cohen’s d=0.25–0.52, p<0.016). Participants with higher motivational beliefs had greater dementia risk reduction.
Conclusions
Improving older adults’ motivation and knowledge may help modify lifestyle behaviors to reduce dementia risk. However, program attrition remains a challenge, suggesting the need for strategies to enhance participant engagement and retention in such interventions.
期刊介绍:
The JPAD Journal of Prevention of Alzheimer’Disease will publish reviews, original research articles and short reports to improve our knowledge in the field of Alzheimer prevention including: neurosciences, biomarkers, imaging, epidemiology, public health, physical cognitive exercise, nutrition, risk and protective factors, drug development, trials design, and heath economic outcomes.JPAD will publish also the meeting abstracts from Clinical Trial on Alzheimer Disease (CTAD) and will be distributed both in paper and online version worldwide.We hope that JPAD with your contribution will play a role in the development of Alzheimer prevention.
