Inflammatory Markers, Hazardous Air Pollutants, and Psychosocial Factors
Hazardous Air Pollutants, Positivity, and Inflammation (HAPPI) Study
Background
American Indian women in southeastern North Carolina have higher cardiovascular mortality rates than White or African American women. Inflammatory processes may underlie racial disparities in cardiovascular outcomes and may be critical to understanding population-specific drivers and potential buffers among vulnerable groups. Environmental air pollutants, especially ambient particulate matter (PM), is known to be an important catalyst in cardiovascular-associated inflammation. Positive psychosocial states, which predict low levels of inflammatory gene expression, could serve to mitigate or reverse the inflammatory response to PM and ultimately lead to better cardiovascular health outcomes.
Objective
In the Mentored Patient-Oriented Research Career Development Award, entitled Inflammatory Markers, Hazardous Air Pollutants, and Psychosocial Factors (5 K23 ES027026-04), we will examine the interplay among environmental air pollutant exposures, cardiovascular-associated inflammation, and psychosocial factors in a sample of 150 American Indian (Lumbee) women. The Specific Aims are to 1) examine the association between PM and cardiovascular-associated inflammatory markers in American Indian women; 2) examine the association between psychosocial states and cardiovascular-associated inflammatory markers in American Indian women; and 3) determine whether positive psychosocial states buffer (moderate) the association between PM and cardiovascular-associated inflammatory markers in American Indian women.
