Medical Research: What is the background for this study? What are the main findings?

Response: We assessed physical activity and TV watching in young adults over 25 years to see if there was an association with cognitive function in middle age. Most previous studies have only considered this association in older adults. We found that both low physical activity and high TV watching over time were associated with worse cognitive function.

Medical Research: What should clinicians and patients take away from your report?

Response: I think the main message is that physical activity is an important way to take care of your brain health at any stage of life.

Medical Research: What recommendations do you have for future research as a result of this study?

Response: We’d really like to explore associations with different sedentary behaviors. With the increase in screen-based behaviors in the past 20 years, there’s a vast array of sedentary behaviors, and some may be more cognitively stimulating than others.
