Stress as a Potential Modifier of the Impact of Lead Levels on Blood Pressure: The Normative Aging Study
(National Institute of Environmental Health Sciences, 2007)
Background: Lead exposure and psychological stress have been independently associated with hypertension in various populations, and animal studies suggest that when they co-occur, their effects may be exacerbated. Objectives: ...
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 ...
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 ...
Low-Level Lead Exposure, Metabolic Syndrome, and Heart Rate Variability: The VA Normative Aging Study
(National Institute of Environmental Health Sciences, 2006)
Background: Altered heart rate variability (HRV), a marker of poor cardiac autonomic function, has been associated with sudden cardiac death and heart failure. Objective: We examined the association of low-level lead ...
Modifying Effects of the HFE Polymorphisms on the Association Between Lead Burden and Cognitive Decline
(National Institute of Environmental Health Sciences, 2007)
Background: As iron and lead promote oxidative damage, and hemochromatosis (HFE) gene polymorphisms increase body iron burden, HFE variant alleles may modify the lead burden and cognitive decline relationship. Objective: ...
Cumulative Community-Level Lead Exposure and Pulse Pressure: The Normative Aging Study
(National Institute of Environmental Health Sciences, 2007)
Background: Pulse pressure increases with age in industrialized societies as a manifestation of arterial stiffening. Lead accumulates in the vasculature and is associated with vascular oxidative stress, which can promote ...
Association of Cumulative Lead Exposure with Parkinson’s Disease
(National Institute of Environmental Health Sciences, 2010)
Background: Research using reconstructed exposure histories has suggested an association between heavy metal exposures, including lead, and Parkinson’s disease (PD), but the only study that used bone lead, a biomarker of ...
