Investigating the impact of physical activity and diet on health outcomes in older biracial adults
Official title: Novel Bayesian assessments of device-based physical activity and self-reported dietary intake in joint models of all-cause mortality and type 2 diabetes in a cohort of biracial older US adults
Funded at Trustees of Indiana University · NIH-11081021 · Data updated 2026-11-12
This study is looking at how exercise tracked by devices and what older biracial adults eat can impact their overall health and risk of diabetes, with the hope of finding ways to help them live healthier lives.

Who could benefit from this research
✓Could help
Ideal candidates for this research are biracial adults aged 21 and older who are interested in monitoring their physical activity and dietary habits.
✕Less likely to help
Patients who are not biracial or those under 21 years old may not receive direct benefits from this research.
What this research studies
This research focuses on understanding how device-based physical activity and self-reported dietary intake affect the health of older biracial adults, particularly in relation to all-cause mortality and type 2 diabetes. By using advanced statistical methods, the study aims to address the complexities of measurement errors in health data collected over time. Participants will provide data through wearable devices and dietary surveys, which will be analyzed to uncover important health trends and risks. The goal is to improve health outcomes by better understanding the relationship between lifestyle factors and chronic diseases.
Why it matters
Potential benefit: If successful, this research could lead to improved strategies for preventing type 2 diabetes and enhancing overall health in older adults.
How similar studies have gone: Previous research has shown success in using similar approaches to analyze health data, indicating that this methodology is promising.
