“Maximizing the utility and comparability of accelerometer data from large-scale observational epidemiologic studies”

Observational epidemiologic studies form the “backbone” of our field in providing evidence showing that there is a clear relation between physical behaviors and good health and functioning. Much of what we know today, particularly for long-term health outcomes, comes from such studies. However, these studies need time to mature because the passage of time is required for health outcomes to occur. In contrast, technological advances in devices used to measure physical behavior, as well as the methodology to process the collected data, proceed at a brisk clip.

Thus, epidemiologic studies with accelerometer data from, say, a decade ago that are now accruing sizeable numbers of clinical outcomes will have employed methodology for collecting and processing accelerometer data also from a decade ago. How can such data be made current and useful so as to address important contemporary questions on the associations of physical behaviors with health outcomes? We will use the Women’s Health Study as an example to illustrate how data collected a decade ago may be maximized in order to take full advantage of them, including potential transformations of the data to make them harmonizable with those from other studies.

University of Illinois Chicago

Issues and Solutions in the Measurement of Physical Activity and Multiple Sclerosis: Lessons Learned and Implications for Other Neurological Diseases.

This presentation will focus on the history and application of accelerometers in persons living with multiple sclerosis, and extension into other populations living with chronic diseases and conditions such as Parkinson’s disease and wheelchair users

Biography

Prof. Robert Motl has systematically developed a research agenda that focuses on physical activity and its measurement, predictors, and consequences in persons with neurological diseases, particularly multiple sclerosis (MS). Prof. Motl has generated a body of research on the validity of common physical activity measures in persons with MS. This has resulted in foundational research on quantifying differences in physical activity, particularly rates of moderate-to-vigorous physical activity, in persons with MS. These two lines of research have provided the basis for examining the outcomes of physical activity in MS, particularly beneficial adaptations in brain structure, cognition, depression, fatigue, walking disability, and quality of life. Prof. Motl has undertaken research on social-cognitive predictors of physical activity that has informed the design of behavioral interventions for increasing physical activity in MS. This agenda serves as a test-bed for application and expansion into other conditions such as spinal cord injury and Parkinson’s disease.

“Avoiding Catastrophe during a Fall: Insights from Video Capture on the Landing Strategies of Older Adults during Real-life Falls”

How do older adults avoid injury during a fall? Any fall has the potential to cause catastrophic injury. Yet only about 5% of falls by older adults in long-term care result in serious injury. This talk will review evidence from video footage of over 3000 real-life falls experienced by older adults in long-term care, on how protective “safe landing” responses separate injurious and non-injurious falls.

“Evolution of public health physical activity applications of accelerometers; a personal perspective.”

 The use of accelerometers to assess physical activity for research and population surveillance has increased rapidly since 2000 with publications on physical activity and accelerometers increasing more than 50-fold. Accelerometer-based measures were included in multiple cohorts and population surveillance. Concurrently, device technology was rapidly evolving as was understanding of the relationship between physical activity behavior and the signal data available from accelerometer-based devices. This talk will provide an overview of significant events over this period as well as address the current challenge of bridging physical activity recommendations based on reported behavior with assessment based on device measures.

Biography

Until his recent retirement, Dr. Richard (Rick) Troiano was a Program Director in the Risk Factor Assessment Branch of the Epidemiology and Genomics Research Program in NCI’s Division of Cancer Control and Population Sciences (DCCPS). Dr. Troiano promotes the validation and use of accelerometer-based devices in the assessment of physical activity in research and population surveillance. He worked with the 2011-2014 National Health and Nutrition Examination Survey (NHANES) to implement the use of devices in the survey to obtain objective measures of participants’ physical activity-related movement and sleep, as well as body strength, and was the lead on inclusion of accelerometers for the first time in NHANES in 2003-2006. He is interested in promoting improved understanding of the information obtained from devices and self-reports and the analytic implications of different data sources. Dr. Troiano also supports federal efforts to promote health-enhancing physical activity, as evidenced by his service as co-executive secretary for the development of the Physical Activity Guidelines for Americans, 2nd edition. Dr. Troiano also was on detail to the Office of Disease Prevention and Health Promotion as Coordinator for the development of 2008 Physical Activity Guidelines for Americans and to the Office of the Surgeon General to support development of Step it Up! The Surgeon General’s Call to Action to Promote Walking and Walkable Communities. Most recently, he served as a member of Guideline Development Group for the 2020 WHO Guidelines on Physical Activity and Sedentary Behaviour.

Let’s dance around the world: Addressing WEIRDNESS in the assessment of physical behavior

I strongly believe that diversity and inclusion in science leads to better science, more innovations and more relevant outcomes that better serves society at large. Historically, scientific research is quite WEIRD (Western, Educated, Industrialized, Rich, and Democratic1) and this WEIRDNESS not only applies to study samples but definitely also to researchers themselves. WEIRD research leads to WEIRD results that better serve a small privileged group of WEIRD people, widening inequalities. How does this WEIRDNESS affect measurement of physical behaviour? I believe that collaborating within our small circle of  scientific friends with similar backgrounds and perspectives results in bias and hinders innovation. As a result we end up missing out on the valuable holistic viewpoint that more inclusive science would gain.

In this lecture, I am keen to share examples of how I strive to make research on measurement of physical behaviour more inclusive by linking a wide diversity of ideas, perspectives and living environments. More diversity and inclusiveness makes our collective dance more beautiful and impactful!
