Diabetes, Obesity, and Hypertension May Enhance Associations between Air Pollution and Markers of Systemic Inflammation
(National Institute of Environmental Health Sciences, 2006)
Airborne particulate matter (PM) may lead to increased cardiac risk through
an inflammatory pathway. Therefore, we investigated associations
between ambient PM and markers of systemic inflammation among repeated
measures ...
Increased Risk of Paroxysmal Atrial Fibrillation Episodes Associated with Acute Increases in Ambient Air Pollution
(National Institute of Environmental Health Sciences, 2006)
Objectives: We reported previously that 24-hr moving average ambient air pollution concentrations were positively associated with ventricular arrhythmias detected by implantable cardioverter defibrillators (ICDs). ICDs ...
Lead Levels and Ischemic Heart Disease in a Prospective Study of Middle-Aged and Elderly Men: The VA Normative Aging Study
(National Institute of Environmental Health Sciences, 2007)
Background: Lead exposure has been associated with higher blood pressure, hypertension, electrocardiogram abnormalities, and increased mortality from circulatory causes.Objective We assessed the association between bone ...
The Relationship Between Ambient Air Pollution and Heart Rate Variability Differs for Individuals with Heart and Pulmonary Disease
(National Institute of Environmental Health Sciences, 2005)
Associations between concentrations of ambient fine particles [particulate matter < 2.5 μm aerodynamic diameter (PM\(_{2.5}\))] and heart rate variability (HRV) have differed by study population. We examined the effects ...
Cumulative Exposure to Lead in Relation to Cognitive Function in Older Women
(National Institute of Environmental Health Sciences, 2008)
Background: Recent data indicate that chronic low-level exposure to lead is associated with accelerated declines in cognition in older age, but this has not been examined in women. Objective: We examined biomarkers of lead ...
Association between hemochromatosis genotype and lead exposure among elderly men: the normative aging study.
(2004)
Because body iron burden is inversely associated with lead absorption, genes associated with hemochromatosis may modify body lead burden. Our objective was to determine whether the C282Y and/or H63D hemochromatosis gene ...
Pesticides and Health Effects: Karpati et al. Respond
(National Institue of Environmental Health Sciences, 2005)
Estimating the Independent Effects of Multiple Pollutants in the Presence of Measurement Error: An Application of a Measurement-Error–Resistant Technique
(2004)
Misclassification of exposure usually leads to biased estimates of exposure–response associations. This is particularly an issue in cases with multiple correlated exposures, where the direction of bias is uncertain. It is ...
The effects of socioeconomic status and indices of physical environment on reduced birth weight and preterm births in Eastern Massachusetts
(BioMed Central, 2008)
Background: Air pollution and social characteristics have been shown to affect indicators of health. While use of spatial methods to estimate exposure to air pollution has increased the power to detect effects, questions ...
Effect of Calcium Supplementation on Blood Lead Levels in Pregnancy: A Randomized Placebo-Controlled Trial
(National Institute of Environmental Health Sciences, 2008)
Background: Prenatal lead exposure is associated with deficits in fetal growth and neurodevelopment. Calcium supplementation may attenuate fetal exposure by inhibiting mobilization of maternal bone lead and/or intestinal ...
