Background:
The exploration of interventions to delay aging is an emerging topic that promotes healthy aging. The multidomain intervention has the potential to be applied in the field of aging because it concentrates on the functional ability of older adults. There is currently no literature reporting on a multidomain intervention involving cognition, exercise and nutrition for delaying aging.
Methods:
The Multidomain Intervention for Delaying Aging in Community-dwelling Older Adults (MIDA) is a Zelen-design randomized controlled trial with a 6-month intervention duration. The multidomain intervention comprises cognitive training, exercise training, and nutritional guidance, delivered through both group sessions and individual family interventions. A total of 248 participants aged 60 to 85 years will be randomized to the intervention group or control group and followed up for 12 months. The primary outcome is the change in epigenetic age acceleration and pace of aging following the multidomain intervention. The secondary outcomes are the changes in frailty score and intrinsic capacity Z-score. Other outcomes include physical functions, body composition, aging biomarkers, inflammatory markers, haematology and biochemistry parameters, and lifestyle factors.
Conclusions:
This study will explore the effects of the multidomain intervention on delaying aging in community-dwelling older adults. We aim to introduce a new approach to delaying aging and offer a practical multidomain intervention strategy for healthcare institutions.
