Early environment, emotions, responses to stress, and health

A harsh early family environment is related to mental and physical health in adulthood. An important question is why family environment in childhood is associated with these outcomes so long after its initial occurrence. We describe a program of research that evaluates a model linking these variables to each other. Specifically, we hypothesize that low social competence and negative emotional states may mediate relations between a harsh early family environment and physiological/neuroendocrine responses to stress, as well as long-term health outcomes. We report evidence that the model characterizes self-rated health, cortisol responses to stress, and, in males only, elevated cardiovascular responses to stress. We discuss how the social context of early life (such as SES) may affect the family environment in ways that precipitate adverse health consequences. Perspectives on comorbidities in physical and mental health are discussed.     

Pathways to resilience: maternal nurturance as a buffer against the effects of childhood poverty on metabolic syndrome at midlife

Children raised in families with low socioeconomic status (SES) go on to have high rates of chronic illness in adulthood. However, a sizable minority of low-SES children remain healthy across the life course, which raises questions about the factors associated with, and potentially responsible for, such resilience. Using a sample of 1,205 middle-aged Americans, we explored whether two characteristics--upward socioeconomic mobility and early parental nurturance--were associated with resilience to the health effects of childhood disadvantage. The primary outcome in our analyses was the presence of metabolic syndrome in adulthood. Results revealed that low childhood SES was associated with higher prevalence of metabolic syndrome at midlife, independently of traditional risk factors. Despite this pattern, half the participants raised in low-SES households were free of metabolic syndrome at midlife. Upward social mobility was not associated with resilience to metabolic syndrome. However, results were consistent with a buffering scenario, in which high levels of maternal nurturance offset the metabolic consequences of childhood disadvantage.     

Some Comments on the Methodological Significance of the Definition of a Response

Evidence in the present study, in conjunction with evidence in previous studies, indicates that sensory or perceptual factors do not account for the slowing that occurs in later life. Elderly Ss are slower than young adult Ss, but, up to the point of fairly weak stimulation (55 db), they are as slow in relation to auditory stimuli that are loud and easy to perceive as they are to stimuli more difficult to perceive. An unanticipated interaction involving stimulus intensity was observed which warrants further attention. When, in the course of the study, the intensity of stimulation was systematically decreased, reaction times (RTs) of older Ss with a .5 second preparatory interval (PI) were much slower than when the intensity of stimulation was systematically increased.

An exploratory study was also carried out. In this study, the pacing of stimulus events was predictable, and Ss were instructed to take advantage of this. RTs were quicker with this procedure than with traditional RT procedures, but not significantly more for old adult Ss than for younger ones. However, the level of significance was such as to suggest that timing may be an important clue to the slowing in later life.     

Risky families: family social environments and the mental and physical health of offspring

Risky families are characterized by conflict and aggression and by relationships that are cold, unsupportive, and neglectful. These family characteristics create vulnerabilities and/or interact with genetically based vulnerabilities in offspring that produce disruptions in psychosocial functioning (specifically emotion processing and social competence), disruptions in stress-responsive biological regulatory systems, including sympathetic-adrenomedullary and hypothalamic-pituitary-adrenocortical functioning, and poor health behaviors, especially substance abuse. This integrated biobehavioral profile leads to consequent accumulating risk for mental health disorders, major chronic diseases, and early mortality. We conclude that childhood family environments represent vital links for understanding mental and physical health across the life span.     

Accounting for changes in social support among married older adults: insights from the MacArthur Studies of Successful Aging

Using longitudinal, community-based data from the MacArthur Studies of Successful Aging, the authors examined determinants of changes in social support receipt among 439 married older adults. In general, social support increased over time, especially for those with many preexisting social ties, but those experiencing more psychological distress and cognitive dysfunction reported more negative encounters with others. Gender affected social support receipt: Men received emotional support primarily from their spouses, whereas women drew more heavily on their friends and relatives and children for emotional support. Discussion centers on the importance of social support provision to those with the greatest needs.     

Toward a model of positive health

This article proposes a model of positive health based on a human-system framework. Such a framework is comprehensive in that (a) it encompasses all of the human system's behavioral subsystems (biochemical, physiological, perceptual, cognitive, and interpersonal), and (b) it permits a higher asymptote of health conceptualization and measurement than that afforded by Western biomedical theory. The article sets forth the conceptual basis of the model and reviews empirical studies that support the model. Finally, the article explores implications of the model for health research, for programs of health enhancement, and for the role of the behavioral sciences in health theory.     

Personality integration and social schemata1

This study was designed to determine whether persons of differing levels of personality integration utilize different response sets to govern their personal space boundaries in relationships with parents and peers. These response sets or “social schemata” were operationally defined by Kuethe's (1962a) free placement felt figures technique and by tape recorded interviews with 30 female and 30 male undergraduates. Findings indicate that personality integration is significantly related to equality with parents and peers, to women's perceived closeness to parents, to the variability of personal space boundaries, and to “communicative richness” when individuals are asked to describe their interpersonal relationships verbally.     

Childhood parental warmth and heart rate variability in midlife: Implications for health

The current study investigated high‐frequency heart rate variability (HF‐HRV) as a potential mediator between childhood parental warmth and later health and mortality outcomes. Participants were 1,255 adults (56.9% female). Childhood parental warmth was reported retrospectively at mean age 46; resting HF‐HRV was measured at mean age 57; cardiovascular health and self‐evaluated health were assessed at mean ages 57 and 63, and mortality records extracted at mean age 63. Results revealed a positive association between childhood parental warmth and resting HF‐HRV, as well as associations between higher HF‐HRV and reduced risk of having a later cardiovascular health problem and of mortality by age 63. Mediation analyses revealed a small significant indirect effect of parental warmth, through HF‐HRV, on cardiovascular health.
