Physical activity has been demonstrated to have a clear beneficial effect on multiple health domains in older adults including preservation of cognitive performance. However, older adults spend most of their time in sedentary behaviors which, independent of the effects of physical activity, have been linked to adverse health outcomes such as poor glycemic control. Due to limited research, the relationship between sedentary behavior and cognition is unclear. We investigated this relationship in a sample of cognitively intact older adults. Sedentary behavior was objectively measured using a thigh worn activPALTM postural monitor for seven days. Cognitive data were collected prior to wearing the activPALTM as part of the University of Kansas Alzheimer’s Disease Center’s standardized battery. We found that older adults spent 73.04% (SD = 7.3) of their day sedentary. We found no statistically significant correlations between the percentage of time spent in sedentary behaviors and scores on the MMSE, Selective Reminding Test, WAIS Block Design, free recall of animals and vegetables, Boston Naming Test, and Trails A or Trails B. A moderate significant negative correlation between Stroop interference and sedentary behavior was found (r= -.386, n= 53, p=.004). These results suggest that there may be domain specific influences of sedentary behavior and cognition. This implies that studies evaluating overall cognition may not be as effective at understanding the relationship between these variables. Future studies will further investigate the relationship between sedentary behavior and areas of executive function including selective attention, automaticity, inhibitory processes, and executive control through longitudinal evidence.
