Key Research Areas
Physical Activity and Sedentary Behavior
A significant portion of Dr. Hayes’s research delves into understanding how different intensities and durations of physical activity, as well as sedentary behaviors, influence cardiometabolic health. Her notable publication, a systematic literature review focusing on the tracking of physical activity from adolescence into adulthood, underscored the importance of accurate and objective methods for assessing physical activity levels. This influential work provides critical data for policymakers and health practitioners, aiding in the creation of targeted public health strategies and interventions aimed at reducing sedentary lifestyles.
Innovative Measurement Techniques
Dr. Hayes is renowned for her pioneering work in the development and validation of wearable technology for precise physical activity measurement. By establishing robust count-to-activity thresholds for adolescent populations, her research facilitates standardized data collection methods. This innovation enables more reliable cross-comparisons between various research studies and enhances the validity and reliability of data informing public health policies.
Applied Research and Public Health Contributions
Practical Interventions
Dr. Hayes has also contributed significantly to practical intervention studies designed to mitigate sedentary lifestyles. One notable example is her study utilizing electronic passive prompts to combat prolonged sedentary behavior among remote workers during the COVID-19 pandemic. Findings from this research indicated that these technology-based prompts successfully reduced prolonged sedentary periods and increased engagement in light-intensity physical activities. These results highlight effective and simple interventions applicable to improving workplace health and wellness programs.
Influence on Policy and Guidelines
Through her meticulous and evidence-based research, Dr. Hayes has had a tangible impact on public health policies and guidelines designed to address the adverse health effects associated with sedentary lifestyles. Her contributions ensure that health guidelines are both scientifically rigorous and practically feasible, supporting health promotion efforts at both the national and global levels.
