Associations between air pollution and perceived stress: the Veterans Administration Normative Aging Study
Mehta, Amar J; Kubzansky, Laura D; Coull, Brent A; Kloog, Itai; Koutrakis, Petros; Sparrow, David; Spiro, Avron; Vokonas, Pantel; Schwartz, Joel (BioMed Central, 2015)Background: There is mixed evidence suggesting that air pollution may be associated with increased risk of developing psychiatric disorders. We aimed to investigate the association between air pollution and non-specific ... -
Associations between Changes in City and Address Specific Temperature and QT Interval - The VA Normative Aging Study
Mehta, Amar J.; Kloog, Itai; Zanobetti, Antonella; Coull, Brent A.; Sparrow, David; Vokonas, Pantel; Schwartz, Joel (Public Library of Science, 2014)Background: The underlying mechanisms of the association between ambient temperature and cardiovascular morbidity and mortality are not well understood, particularly for daily temperature variability. We evaluated if daily ... -
Cardiac Autonomic Dysfunction: Particulate Air Pollution Effects Are Modulated by Epigenetic Immunoregulation of Toll‐like Receptor 2 and Dietary Flavonoid Intake
Zhong, Jia; Colicino, Elena; Lin, Xinyi; Mehta, Amar; Kloog, Itai; Zanobetti, Antonella; Byun, Hyang‐Min; Bind, Marie‐Abèle; Cantone, Laura; Prada, Diddier; Tarantini, Letizia; Trevisi, Letizia; Sparrow, David; Vokonas, Pantel; Schwartz, Joel; Baccarelli, Andrea A. (Blackwell Publishing Ltd, 2015)Background: Short‐term fine particles (PM2.5) exposure is associated with reduced heart rate variability, a strong predictor of cardiac mortality among older people. Identifying modifiable factors that confer susceptibility ... -
Dietary anthocyanin intake and age-related decline in lung function: longitudinal findings from the VA Normative Aging Study123
Mehta, Amar J; Cassidy, Aedín; Litonjua, Augusto A; Sparrow, David; Vokonas, Pantel; Schwartz, Joel (American Society for Nutrition, 2016)Background: It is unknown whether habitual intake of dietary flavonoids, known for their antioxidative and anti-inflammatory properties, affects longitudinal change in lung function. Objective: We investigated whether ... -
Heart Rate Variability in Association with Frequent Use of Household Sprays and Scented Products in SAPALDIA
Mehta, Amar Jayant; Adam, Martin; Schaffner, Emmanuel; Barthélémy, Jean-Claude; Carballo, David; Gaspoz, Jean-Michel; Rochat, Thierry; Schindler, Christian; Schwartz, Joel David; Zock, Jan-Paul; Künzli, Nino; Probst-Hensch, Nicole (National Institute of Environmental Health Sciences, 2012)Background: Household cleaning products are associated with adverse respiratory health outcomes, but the cardiovascular health effects are largely unknown. Objective: We determined if long-term use of household sprays and ... -
A Large Scale Gene-Centric Association Study of Lung Function in Newly-Hired Female Cotton Textile Workers with Endotoxin Exposure
Zhang, Ruyang; Zhao, Yang; Chu, Minjie; Mehta, Amar Jayant; Wei, Yongyue; Liu, Yao; Xun, Pengcheng; Bai, Jianling; Yu, Hao; Su, Li; Zhang, Hongxi; Hu, Zhibin; Shen, Hongbing; Chen, Feng; Christiani, David C. (Public Library of Science, 2013)Background: Occupational exposure to endotoxin is associated with decrements in pulmonary function, but how much variation in this association is explained by genetic variants is not well understood. Objective: We aimed ... -
Long-Term Exposure to Ambient Fine Particulate Matter and Renal Function in Older Men: The Veterans Administration Normative Aging Study
Mehta, Amar J.; Zanobetti, Antonella; Bind, Marie-Abele C.; Kloog, Itai; Koutrakis, Petros; Sparrow, David; Vokonas, Pantel S.; Schwartz, Joel D. (National Institute of Environmental Health Sciences, 2016)Background: It is unknown if ambient fine particulate matter (PM2.5) is associated with lower renal function, a cardiovascular risk factor. Objective: We investigated whether long-term PM2.5 exposure was associated with ... -
Residential Black Carbon Exposure and Circulating Markers of Systemic Inflammation in Elderly Males: The Normative Aging Study
Fang, Shona C.; Mehta, Amar Jayant; Alexeeff, Stacey E.; Gryparis, Alexandros; Coull, Brent Andrew; Vokonas, Pantel S.; Christiani, David C.; Schwartz, Joel David (National Institute of Environmental Health Sciences, 2012)Background: Traffic-related particles (TRPs) are associated with adverse cardiovascular events. The exact mechanisms are unclear, but systemic inflammatory responses likely play a role. Objectives: We conducted a repeated ...
