OBJECTIVES Midlife in the United States (MIDUS) is a national study of health and aging among individuals aged 25 to 74 at baseline (1995-1996). Longitudinal survey assessments (2004-2005), were followed by biological assessments on a subsample (aged 35-85).To facilitate public use, we describe the protocol, measures, and sample. METHOD Respondents(More)
Despite the increasing evidence linking aspects of the social environment to a range of health outcomes, important questions remain concerning the precise mechanisms or pathways through which social circumstances exert their influence. Biological pathways are one important area of current research interest. Using data from the Social Environment and(More)
Natural disasters, such as earthquakes, can have deleterious consequences for physical and psychological health. In this study, we investigate variability in resilience to depressive symptoms in the aftermath of a massive earthquake that struck Taiwan in 1999. We analyze data on 1160 older individuals from a national, longitudinal survey with interviews(More)
The theory of allostatic load describes how the cumulative experience of emotional challenges and stressful events over the life course may take a significant physiological toll on multiple interrelated systems of the body. Various summary measures of these effects have been proposed in the literature, but few studies focus on systematically evaluating(More)
We hypothesize that children who are close to their parents are more likely to have attitudes and behavior that are consistent with their parents' values than children who are not close to their parents. Using data from a probability sample of 888 mother-child pairs of white women in the Detroit metropolitan area, we tested this hypothesis, using both(More)
We investigate how biological markers of individual responses to stressful experiences are associated with profiles of physical and mental functioning in a national sample of middle-aged and elderly Taiwanese. Data come from a population-based sample of middle-aged and elderly Taiwanese in 2000. The data combine rich biological measures with self-reported(More)
BACKGROUND This study examines how changes in cognition over time are related to participation in social activities and the extent of social networks. METHODS Data are drawn from a population-based, longitudinal study that began in 1989 among elderly Taiwanese. An over-dispersed Poisson model is used to regress the number of failed cognitive tasks (0-5)(More)
The present study tested the hypothesis that the change in state negative affect (measured as perceived stress) after cognitive challenge moderates the relationship of trait anxiety and anger to vagal recovery from that challenge. Cardiac vagal control (assessed using heart rate variability) and respiratory rate were measured in a sample of 905 participants(More)
The proliferation of biosocial surveys has increased the importance of weighing the costs and benefits of adding biomarker collection to population-based surveys. A crucial question is whether biomarkers offer incremental value beyond self-reported measures, which are easier to collect and impose less respondent burden. We use longitudinal data from a(More)
Increasingly, researchers and health specialists are obtaining information on chronic illnesses from self-reports. This study validates self-reports of two major health conditions, hypertension and diabetes, based on a recent survey in Taiwan (SEBAS 2000). These data, based on a large, nationally representative sample of respondents aged 54 and older,(More)
