Assistant Professor of Occupational and Environmental Health Sciences
Dr. Roberts received her training in environmental health sciences and she has extensive experience working in the fields of public health, environmental epidemiology, and human health risk assessment. Her current focus is to develop her research portfolio, which occupies two overlapping themes. The first theme encompasses the areas of risk assessment and environmental epidemiology (e.g. examining the human health risks of low frequency sound exposure generated by wind turbines). And closely related to the first theme, the second theme pertains to man-made environmental impacts and influences on public health. Dr. Roberts has a considerable interest in examining the relationship between the built environment and physical (e.g. obesity) and mental (e.g. depression) health outcomes within both environmental and socioeconomic contexts.
Physical inactivity, ambient air pollution and obesity are modifiable risk factors for non-communicable diseases, with the former accounting for ten percent of premature deaths worldwide. Although community level interventions may target each simultaneously, research on the relationship between these risk factors is lacking. Thus, an important research question is whether obese and overweight adults who are exposed to higher levels of ambient air pollution exhibit lower levels of physical activity and whether the relationship between air pollution and physical inactivity exacerbate the underlying health disparities.
This cross-sectional study will examine the association of ambient air pollution with physical inactivity among obese and overweight adults while also comparing spatial interpolation methods to determine the best predictor for ambient air pollution exposures throughout the U.S.
