Joint hypothetical interventions targeting peak expiratory flow, depression symptoms, and pain achieved the largest estimated reduction in 4-year motoric cognitive risk syndrome risk (RR 0.74), and combined social participation and physical activity also lowered estimated risk (RR 0.78), supporting multi-domain prevention strategies that need testing in randomized controlled trials.
About one in five older Chinese adults developed incident motoric cognitive risk syndrome (MCR) over 4 years.
A joint hypothetical intervention on peak expiratory flow, depression symptoms, and pain produced the largest estimated MCR risk reduction.
A joint hypothetical intervention on social participation and physical activity also lowered estimated MCR risk.
Candidate intervention targets were identified using combined theory-driven and data-driven approaches within an intrinsic capacity framework.
The authors conclude that multi-domain interventions integrating respiratory function, psychological resilience, and pain management are promising for MCR prevention, and that randomized trials are needed.
This study followed 2299 Chinese adults aged 60 and older for four years to see who developed motoric cognitive risk syndrome, a condition combining slow walking with subjective memory complaints that signals higher dementia risk. About 19% developed it during that time. Using a statistical method that simulates 'what if' scenarios, the researchers estimated how much risk might drop if certain factors were improved. Improving lung function (peak expiratory flow), reducing depression symptoms, and managing pain together was estimated to lower risk by about 26% (risk ratio 0.74). Increasing social participation and physical activity together was estimated to lower risk by about 22% (risk ratio 0.78). These are modeled estimates from observational data, not results from an actual intervention. This research suggests that approaches addressing several areas of health at once may be worth pursuing, but randomized controlled trials are needed to find out whether they truly prevent the syndrome.
