Dr. Kerr is a leader in physical activity research and assessment in older adults. Her webinar outlines the importance of improving measurement precision of both physical activity and sitting time using mobile sensors and machine learning techniques. Dr. Kerr discusses the infrastructure investments that have been necessary, challenges of working with computer scientists, and the need for stronger validation of new measurement techniques.
This 6-part webinar series provides an overview of physical activity as a multidimensional health behavior; an in-depth review of methods to measure active and sedentary behaviors by self-report; and an exploration of important issues when assessing physical activity in diverse populations.
These modules are designed to complement the Measures Registry and Measures Registry User Guides and assist researchers and practitioners with choosing the best measures across the four domains of the Measures Registry: individual diet, food environment, individual physical activity and physical activity environment.
As part of the ODP’s 2012 Physical Activity and Disease Prevention Workshop: Identifying Research Priorities session #3: Measurement of Physical Activity Behavior, Dr. Intille discusses the devices that might be used to measure and study physical activity versus sedentary behavior.
This journal supplement summarizes and builds upon a workshop which convened researchers from diverse sectors and organizations. The supplement discusses current technologies for objective physical activity monitoring, provides recommendations for the use of these technologies, and explores future directions in the development of new tools and approaches.
It presents best practices for using physical activity monitors in population-based research, explores modeling of physical activity outcomes from wearable monitors, and discusses statistical considerations in the analysis of accelerometry-based activity monitor data. It also examines monitor equivalency issues and discusses current use and best practices for accelerometry with particular populations—children, older adults, and adults with functional limitations.
NCI has developed two online resources for use in selecting instruments for various research questions: the Dietary Assessment Primer and the Measures Registry. Both are designed to provide knowledge transfer and facilitate adoption of best assessment practices. This webinar describes each of these resources with a focus on how we can minimize measurement error by opening up access to the best assessment methods.
This webinar introduces the SPADES platform which offers simple, uniform, and rapid ways for researchers and clinicians to collect, store, and analyze high resolution signals on physiologic, inertial, and location data. SPADES is a multi-tier, cloud-based service hosted on the highly scalable Amazon Web Services (AWS) platform.
Part one of the two-part series, Measuring Success in Low-Income Nutrition Education and Obesity Prevention Programs, explores how to use the framework to evaluate nutrition education and obesity prevention programs.
Part two, Strategies and Tools for Measuring the Priority Indicators, highlights the seven SNAP-Ed priority indicators from the Evaluation Framework and shares practical examples of measuring healthy eating behaviors, physical activity, and reduced sedentary behaviors in low-income children and families.
In this Methods: Mind the Gap webinar, Dr. Siobhan Phillips provides an overview of how digital health tools can be used to better understand and optimize physical activity promotion interventions.
