Recent research indicates gender differences in the impact of stress on decision behavior, but little is known about the brain mechanisms involved in these gender-specific stress effects. The current study used functional magnetic resonance imaging (fMRI) to determine whether induced stress resulted in gender-specific patterns of brain activation during a(More)
BACKGROUND Arterial aging is well characterized in industrial populations, but scantly described in populations with little access to modern medicine. Here we characterize health and aging among the Tsimane, Amazonian forager-horticulturalists with short life expectancy, high infectious loads and inflammation, but low adiposity and robust physical fitness.(More)
PURPOSE This study investigated the association between weight change and inflammation in a nationally representative population of US adults aged 40 and older. METHODS Using the US National Health and Nutrition Examination Survey (2005-2008), logistic regression models were used to determine the relationship between high levels of inflammation(More)
Over the past 30 years, policy makers and professionals who provide services to older adults with chronic conditions and impairments have placed greater emphasis on conceptualizing aging in place as an attainable and worthwhile goal. Little is known, however, of the changes in how this concept has evolved in aging research. To track trends in aging in(More)
OBJECTIVES Models of stress incorporate both the environmental demands experienced by individuals (stressors) and the appraisal of these life events (perceptions). Because little is known about the extent to which experience and perceptions are related, we examine this relationship in a nationally representative population of older Taiwanese adults. (More)
Excess weight has generally been associated with adverse health outcomes; however, the link between overweight and health outcomes may vary with socioeconomic, cultural, and epidemiological conditions. We examine associations of weight with indicators of biological risk in three nationally representative populations: the US National Health and Nutrition(More)
BACKGROUND Cognitive and brain reserve theories suggest that aspects of neural architecture or cognitive processes modify the impact of neuropathological processes on cognitive outcomes. While frequently studied in the context of dementia, reserve in delirium is relatively understudied. METHODS We examined the association of three markers of brain reserve(More)
BACKGROUND Cognitive and brain reserve theories suggest that aspects of neural architecture or cognitive processes modify the effect of neuropathological processes on cognitive outcomes. Although frequently studied in the context of dementia, reserve in delirium is understudied. METHODS Using data from a prospective observational study, we examined the(More)
OBJECTIVE Although the impact of widowhood on the surviving spouse's health has been widely documented, there is little empirical research examining whether certain spousal choice decisions and marital sorting patterns predispose individuals to be more vulnerable to the adverse consequences of widowhood for health. DESIGN AND METHOD We use data from the(More)
