Data for the association between physical activity and cognitive outcomes

A positive association between physical activity (PA) and cognition is well-established. However, it is unclear whether this association varies across different demographic and health subgroups. This study involves 2,547 US individuals over 60 from the 2011 to 2014 NHANE cycle. Multivariable regression models measured the associations between PA levels averaged daily PA (MIMS/d) and Peak-30 (MIMS/min) and cognitive indicators (i.e., a composite score of recall, executive function, processing speed, and sustained attention) across the overall sample and subgroups.
