nutrient intake and dietary changes during a 2-year multi-domain lifestyle intervention among older adults: secondary analysis of the finnish geriatric intervention study to prevent cognitive impairment and disability (finger) randomised controlled trial

AbstractAdvancing age increases the risk for diseases and health concerns like cognitive decline, constituting a major public health challenge. Lifestyle, especially healthy diet, affects many risk factors related to chronic diseases, and thus lifestyle interventions among older adults may be beneficial in promoting successful ageing.

The aim of this paper was to describe success of the intervention – that is, how an intervention based on national dietary recommendations affected dietary habits as a part of multi-intervention. Composite dietary intervention adherence score comprising nine distinct goals (range 0–9 points from none to achieving all goals) was 5·0 at baseline, and increased in the intervention group after the 1st (P
