Body weight following a multidomain lifestyle intervention in older adults at risk of dementia - A post-hoc analysis of the AgeWell.de-trial

Lifestyle interventions provide a promising approach to address higher body weight as a risk factor for dementia.

The AgeWell.de-trial was primarily designed to preserve cognitive function and reduce dementia risk. In this post-hoc analysis, we investigated body weight following the multidomain intervention among older adults with overweight or obesity, as well as the role of motivation and confidence regarding weight loss.

Analyses used data from the cluster-randomized AgeWell.de-trial, testing a multidomain intervention (dietary counselling, enhancement of physical, social and cognitive activity, medication review, intervention for cardiovascular risk factors, depressive symptoms/grief, if applicable) over 24 months in adults aged 60 to 77 years at risk for dementia. Associations between intervention allocation and body weight at follow-up were analyzed using linear regression, controlling for covariates, based on multiply imputed data.
