Multidomain Intervention Trial for Preventing Cognitive Decline among Older Adults with Type 2 Diabetes: J-MIND-Diabetes
Background
No multidomain intervention trials have been designed for the prevention of cognitive decline in older adults with type 2 diabetes.
Objectives
To investigate the efficacy of a multidomain intervention in preventing cognitive decline in older adults with type 2 diabetes and cognitive impairment.
Outpatients with type 2 diabetes aged 70–85 years with cognitive impairment.
Intervention
The multidomain intervention program includes management of metabolic and vascular risk factors, exercise, nutritional counseling, and promotion of social participation. Participants in the control group received usual care and treatment for type 2 diabetes.
Measurements
The primary outcome was the change in a composite score combining several neuropsychological tests from baseline to the 18-month follow-up. To assess the differences in cognitive changes between the intervention and control groups, a mixed-effects model for repeated measures was used.
Results
Between March 13, 2019, and May 8, 2020, 361 participants were screened, and 154 were randomly assigned to either the intervention group (n = 81) or the control group (n = 73). Finally, 110 participants completed the trial. The between-group difference in the composite score changes was 0.068 (95% confidence interval, −0.091 to 0.226). Analyses for secondary outcomes indicated a positive impact of the intervention on memory and indicated that the intervention led to changes in dietary habits with increased intakes of niacin and meat, along with weight reduction compared to the control group.
Conclusion
The multidomain intervention did not demonstrate efficacy in preventing cognitive decline. However, this trial provided proof-of-concept evidence that multidomain interventions may offer cognitive benefits and contribute to changes in dietary behavior and weight reduction in older adults with type 2 diabetes and cognitive impairment. These findings should be confirmed in future studies.
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.
