ABSTRACT Quantification of the relationship between community-level chronic stress from neighborhood conditions and individual morale has rarely been reported. In this work, pregnant women were recruited at the prenatal clinics of Harlem Hospital and Columbia Presbyterian Medical Center in the USA, and given an initial questionnaire that included all 27 questions of the Dohrenwend demoralization instrument, as well as questions about household economics and health. An index of chronic community stress (ICCS) was compiled for each of the health areas of the study zone by standardizing and weighting each stressor significantly associated with low birthweight rate and summing the standardized, weighted values. Health areas were divided into ICCS quintiles. The graph of the quintile weighted averages of the index vs. the quintile averages of the demoralization score was an asymmetric inverted 'U' shape that fitted well to a stochastic resonance signal transduction model (adjusted R2=0.73). On average, the women in the worst three quintiles were much heavier than those of the two best quintiles. Women reporting household economic deprivations were significantly more demoralized than the others. Median health area rents were strongly negatively associated with the ICCS. The worst average demoralization score occurred in the middle quintile, a state of coping with both poor community conditions and an economically strained household. Rents bridge community conditions and household economics.

    ABSTRACT: With the increased understanding of the relationship between stress and disease, the role of stress in explaining persistent disparities in health outcomes has received growing attention. One body of research has focused on allostatic load-the "wear and tear" that results from chronic or excessive activation of the stress response. Other research has looked at the link between stress and health behaviors. In this study, we conducted 7 focus groups with a total of 56 people to understand how people living in Highbridge, South Bronx, New York, a low income community with poor health outcomes, perceive stress and its relationship to health. Focus group participants described a direct causal pathway between stress and poor health as well as an indirect pathway through health behaviors, including uncontrolled eating, sleep deprivation, substance abuse, smoking, violence and aggression, and withdrawal and inactivity. Participants articulated a number of theories about why stress leads to these unhealthy behaviors, including self-medication, adaptive behavior, discounting the future, depletion of willpower, and competing priorities. Their nuanced understanding of the link between stress and health elucidates the mechanisms and pathways by which stress may result in disparities in health outcomes and create challenges in changing health behaviors in poor communities like the South Bronx.

    ABSTRACT: What are the social and economic consequences of massive destruction of housing? A case study of the New York City fire epidemic of the 1970s is presented. Decision-makers regarded old neighbourhoods (with low-income families and/or racial minorities) as wastelands and developed policies such as urban renewal and reductions in public services (‘planned shrinkage’) which negatively impacted on the physical and social fabrics. Structural and functional continuity even after a disturbance – ecological resilience – depends on many non-disjunctive ‘loose’ relationships to diffuse these impacts. Systems based on ‘tight’ relationships amplify impacts. Families with resources relocate and reduce the community diversity and the density of loose ties. Low-income families whose homes are destroyed weaken the remaining social networks. The remnant cannot maintain social norms. This displacement leads to two possibilities: many small social networks that do not interact; or one large tight network with low diversity. The former confers pathological resilience; the latter, extreme fragility. Neither enforces social norms or generates political power. Both foster risk behaviours and hamper socialization of youth. Thus, concentrated housing destruction destroys healthy resilience and social control and support. Indirectly, it elevates the mortality rate through increased risk behaviours, high death rates among vulnerable elderly, and infectious and chronic diseases.Quelles sont les conséquences sociales et économiques d'une destruction massive de logements? Il est présenté une étude de cas sur l'épidémie d'incendies des années soixante-dix à New York. Les décisionnaires ont considéré les vieux quartiers (avec leurs familles à faible revenu et/ou leurs minorités raciales) comme des zones à l'abandon et ont développé des politiques telles que la rénovation urbaine et les réductions des services publics («réduction planifiée») qui ont eu des répercussions négatives sur les tissus physiques et sociaux. La continuité structurelle et fonctionnelle, même après une perturbation – la résilience écologique – dépend de nombreuses relations «distendues» non disjonctives permettant de rendre ces répercussions diffuses. Les systèmes basés sur des relations «étroites» amplifient les répercussions. Les familles qui ont les moyens s'installent ailleurs et réduisent la diversité communautaire et la densité des rapports distendus. Les familles à faible revenu dont les habitations sont détruites affaiblissent les tissus sociaux restants. Celles qui restent ne peuvent pas maintenir les normes sociales. Ce déclassement conduit à deux possibilités: de nombreux réseaux sociaux de petite taille qui n'ont pas d'interactions; ou bien un grand réseau aux liens resserrés, mais présentant une faible diversité. Le premier confère une résilience pathologique; le second, une extrême fragilité. Ni l'un, ni l'autre ne renforce les normes sociales, ni ne génère de pouvoir politique. Les deux encouragent les comportements à risque et gênent la socialisation des jeunes. Ainsi, la destruction des habitats concentrés anéantit la résilience saine, ainsi que le contrôle et le soutien sociaux. Indirectement, cela élève le taux de mortalité par l'accroissement des comportements à risque, par l'augmentation des taux de mortalité chez les personnes âgées vulnérables et par les maladies infectieuses et chroniques.Mots clés: stabilité, communautaire, destruction de logements, structure sociale de proximité, réduction planifiée, santé publique, services publics, résilience, vie urbaine, rénovation urbaine

    ABSTRACT: We extend a cognitive paradigm for gene expression based on the asymptotic limit theorems of information theory to the epigenetic epidemiology of complex developmental disorders in humans. In particular, we recognize the fundamental role culture plays in human biology, a heritage mechanism parallel to, and interacting with, the more familiar genetic and epigenetic systems. We do this via a model through which culture acts as another tunable epigenetic catalyst that both directs developmental trajectories, and becomes convoluted with individual ontology, via a mutually-interacting crosstalk mediated by a social interaction that is itself culturally driven. In sum, embedding culture is an essential component of the regulation of human development and its dysfunctions. The cultural and epigenetic systems of heritage may thus provide the ‘missing’ heritability of complex diseases that is currently the subject of much scientific discourse.
