Cognitive function differs across healthy lifestyle behavior profiles a 10-year population-based prospective cohort study

This study explored how lifestyle behaviors affect cognitive health over ten years in older adults in China. Using data from 5,381 individuals aged 65 and older, researchers grouped participants into three lifestyle profiles: active engagement, moderate engagement, and negative engagement. Those in the active group, characterized by healthy diets, regular physical and cognitive activities, and good sleep quality, showed the lowest risk of cognitive decline and slower rates of memory loss. This research underscores that even partial adoption of healthier lifestyles can meaningfully reduce cognitive impairment risks, emphasizing preventive actions for brain health.

Incorporating more healthy habits like regular physical activity, a nutrient-rich diet, cognitive exercises (e.g., puzzles, reading), and maintaining social connections can protect brain health. The findings suggest significant benefits from gradual lifestyle changes, as even moderate adherence lowered cognitive decline risk. Tailoring interventions to an individual’s capacity, especially in older adults, enhances the practicality and impact of such strategies.
