Improving Exercise Adherence With App Technology for At-Risk Adults Living in Rural Kansas and Nebraska

Alzheimer's disease and related dementias are a public health crisis impacting individuals across the world. In the United States, adults living in rural areas face an elevated risk for cognitive impairment mainly due to disparities in care, higher sedentary behavior, and reduced education. This project proposes to assess the impact of a remotely delivered exercise program (i.e., RemoteEx+) through a smartphone application. The app is programmed by our team and provides video demonstrations of exercises, workout regimes, motivational messaging, and weekly ADRD risk reduction education. The project aims to assess with a pre/post design the following aims:

* Aim 1. Assess the RemoteEx+ intervention exercise adherence, efficacy, enjoyment, and quality of life. We hypothesize that rural adults will report high exercise adherence (80% of session adherence), efficacy (\>50% on Self Efficacy for Exercise), and enjoyment (\>5.0 on Intrinsic Motivation Inventory - Interest / Enjoyment Subscale) and that these variables will be positively correlated with quality of life scores (36-Item Short Form Health Survey \[SF-36\]) * Aim 2. Determine the impact of a technology-driven exercise program on blood pressure and functional mobility associated with dementia risk. We hypothesize that the exercise program will result in improvements in blood pressure and functional mobility (2-minute step test and 30-second chair rise test) and that participants with high exercise adherence will see the greatest improvements in biomarkers associated with reduced dementia risk. * Aim 3. Reduce health disparities among rural-dwelling Nebraska and Kansas residents. We hypothesize that RemoteEx+ will reduce barriers to exercise (Barriers to Being Active Quiz and improve knowledge surrounding dementia and modifiable risk factors (Dementia Knowledge Assessment Tool - Version 2 \[DKAT2\]) that will result in fewer lifestyle-related health disparities for the communities involved in this study.

The results from this project will inform whether RemoteEx+ has an impact on the stated outcomes above for adults living in rural areas.
