The significant places of African American adults and their perceived influence on cardiovascular disease risk behaviors.

Journal Article BMC Public Health · November 5, 2021 BACKGROUND: AA living in rural areas of the southeastern U.S. experience a disproportionate burden of cardiovascular disease (CVD) morbidity and mortality. Neighborhood environmental factors contribute to this disparity and may decrease the effectiveness o ... Full text Link to item Cite

Epigenetically mediated electrocardiographic manifestations of sub-chronic exposures to ambient particulate matter air pollution in the Women's Health Initiative and Atherosclerosis Risk in Communities Study.

Journal Article Environ Res · July 2021 BACKGROUND: Short-duration exposure to ambient particulate matter (PM) air pollution is associated with cardiac autonomic dysfunction and prolonged ventricular repolarization. However, associations with sub-chronic exposures to coarser particulates are rel ... Full text Link to item Cite

Abstract P143: Methylome-Wide Association Of DNA Methylation And Aircraft Noise Exposure In The Women’s Health Initiative

Conference Circulation · March 3, 2020 Background: Noise pollution is common and can affect health, but mechanisms underlying this relationship remain incompletely characterized. We therefore examined the novel association between aircraft ... Full text Cite

Abstract P451: Aircraft Noise Exposure As A Novel Risk Factor For Clonal Hematopoiesis Of Indeterminate Potential

Conference Circulation · March 3, 2020 Background: Although the etiology of clonal hematopoiesis of indeterminate potential (CHIP) remains unclear, CHIP-defining somatic mutations within hematopoietic stem cells appear to expand peripheral ... Full text Cite

Leukocyte Traits and Exposure to Ambient Particulate Matter Air Pollution in the Women's Health Initiative and Atherosclerosis Risk in Communities Study.

Journal Article Environ Health Perspect · January 2020 BACKGROUND: Inflammatory effects of ambient particulate matter (PM) air pollution exposures may underlie PM-related increases in cardiovascular disease risk and mortality, although evidence of PM-associated leukocytosis is inconsistent and largely based on ...

Methylome-wide association study provides evidence of particulate matter air pollution-associated DNA methylation.

Journal Article Environ Int · November 2019 BACKGROUND: DNA methylation (DNAm) may contribute to processes that underlie associations between air pollution and poor health. Therefore, our objective was to evaluate associations between DNAm and ambient concentrations of particulate matter (PM) ≤2.5, ... Full text Link to item Cite

The Association of Sport and Exercise Activities With Cardiovascular Disease Risk: The Atherosclerosis Risk in Communities (ARIC) Study.

Journal Article J Phys Act Health · September 1, 2019 BACKGROUND: This study assessed the independent associations between participation in self-reported sport and exercise activities and incident cardiovascular disease (CVD). METHODS: Data were from 13,204 participants in the Atherosclerosis Risk in Communit ... Full text Link to item Cite

Air pollution-associated changes in biomarkers of diabetes risk.

Journal Article Environmental epidemiology (Philadelphia, Pa.) · August 2019 BackgroundAmbient particulate matter (PM) and nitrogen oxide (NOx) air pollution may be diabetogenic.ObjectiveTo examine longitudinal associations of short- and longer-term mean PM ≤10 μm (PM10), PM ≤2.5 μm (PM2 ...

Transitions from Ideal to Intermediate Cholesterol Levels may vary by Cholesterol Metric.

Journal Article Sci Rep · February 9, 2018 To examine the ability of total cholesterol (TC), a low-density lipoprotein cholesterol (LDL-C) proxy widely used in public health initiatives, to capture important population-level shifts away from ideal and intermediate LDL-C throughout adulthood. We est ... Full text Link to item Cite

Where Are Adults Active? An Examination of Physical Activity Locations Using GPS in Five US Cities.

Journal Article J Urban Health · August 2017 Increasing physical activity (PA) at the population level requires appropriately targeting intervention development. Identifying the locations in which participants with various sociodemographic, body weight, and geographic characteristics tend to engage i ... Full text Link to item Cite

Heterogeneity in Blood Pressure Transitions Over the Life Course: Age-Specific Emergence of Racial/Ethnic and Sex Disparities in the United States.

Journal Article JAMA Cardiol · June 1, 2017 IMPORTANCE: Many studies have assessed racial/ethnic and sex disparities in the prevalence of elevated blood pressure (BP) from childhood to adulthood, yet few have examined differences in age-specific transitions between categories of BP over the life cou ...

Are buffers around home representative of physical activity spaces among adults?

Journal Article Health Place · May 2017 Residential buffers are frequently used to assess built environment characteristics relevant to physical activity (PA), yet little is known about how well they represent the spatial areas in which individuals undertake PA. We used System for Observing Play ... Full text Link to item Cite

Deriving a GPS Monitoring Time Recommendation for Physical Activity Studies of Adults.
