Abstract
INTRODUCTION Despite growing scholarship on the social determinants of health (SDoH), wider action remains in its early stages. Broad public understanding of SDoH can help catalyse such action. This paper aimed to document public perception of what matters for health from countries with broad geographic, cultural, linguistic, population composition, language and income level variation. METHODS We conducted an online survey in Brazil, China, Germany, Egypt, India, Indonesia, Nigeria and the USA to assess rankings of what respondents thought matters for health and what they perceived decision makers think matters for health. We analysed the percentages of each determinant rated as the most important for good health using two metrics: the top selection and a composite of the top three selections. We used two-tailed χ2 test for significance testing between groups. RESULTS Of 8753 respondents, 56.2% (95% CI 55.1% to 57.2%) ranked healthcare as the most important determinant of good health using the composite metric. This ranking was consistent across countries except in China where it appeared second. While genetics was cited as the most important determinant by 22.3% (95% CI 21.5% to 23.2%) of the overall sample with comparable rates in most countries, the percentage increased to 33.3% (95% CI 30.5% to 36.3%) in Germany and 35.9% (95% CI 33.0% to 38.8%) in the USA. Politics was the determinant with the greatest absolute difference (18.5%, 95% CI 17.3% to 19.6%) between what respondents considered matters for health versus what they perceived decision makers think matters for health. CONCLUSION The majority of people consider healthcare the most important determinant of health, well above other social determinants. This highlights the need for more investment in communication efforts around the importance of SDoH.

Impacts of a perinatal exposure to manganese coupled with maternal stress in rats: Tests of untrained behaviors. Neurotoxicol Teratol 2022; 91:107088. [PMID: 35278630 PMCID: PMC9133146 DOI: 10.1016/j.ntt.2022.107088] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/06/2021] [Revised: 03/01/2022] [Accepted: 03/06/2022] [Indexed: 11/21/2022]
Abstract
Manganese (Mn), an element that naturally occurs in the environment, has been shown to produce neurotoxic effects on the developing young when levels exceed physiological requirements. To evaluate the effects of this chemical in combination with non-chemical factors pregnant Long-Evans rats were treated with 0, 2, or 4 mg/mL Mn in their drinking water from gestational day (GD) 7 to postnatal day (PND) 22. Half of the dams received a variable stress protocol from GD13 to PND9, that included restraint, small cage with reduced bedding, exposure to predator odor, intermittent intervals of white noise, lights on for 24 h, intermittent intervals of lights on during dark cycle and cages with grid floors and reduced bedding. One male and one female offspring from each litter were tested to assess untrained behavior. Ultrasonic vocalizations (USV) were recorded from PND13 pups while they were isolated from the litter. Locomotor activity (MA) was measured in figure-eight mazes at PND 17, 29, and 79 (different set of rats at each time point). Social approach (SA) was tested at PND48. Acoustic startle response (ASR) and pre-pulse inhibition (PPI) were measured starting at PND58. At PND53 a sweetness preference for a chocolate flavored milk solution was assessed. There were sex related differences on several parameters for the USVs. There was also a Mn by stress by sex interaction with the females from the 4 mg/mL stressed dams having more frequency modulated (FM) call elements than the 4 mg/mL non-stressed group. There was an effect of Mn on motor activity but only at PND29 with the 2 mg/mL group having higher counts than the 0 mg/mL group. The social approach test showed sex differences for both the habituation and test phase. There was an effect of Mn, with the 4 mg/mL males having a greater preference for the stimulus rat than did the 0 mg/mL males. There was also a stress by sex interaction. The ASR and PPI had only a sex effect. Thus, with only the FM call elements having a Mn by stress effect, and the PND29 MA and SA preference index having a Mn effect but at different doses requires further investigation.

Impacts of a perinatal exposure to manganese coupled with maternal stress in rats: Maternal somatic measures and the postnatal growth and development of rat offspring. Neurotoxicol Teratol 2021; 90:107061.

Abstract
Psychological stress experienced by the mother during pregnancy has been associated with emotional and cognitive disorders in children such as depression and anxiety. Socioeconomically disadvantaged populations are vulnerable to adverse life experiences and can also be disproportionally exposed to environmental contaminants. To better understand the neurodevelopmental impacts of an environmental toxicant coupled with elevated psychological stress, we exposed pregnant rats to a series of perinatal stressors. Manganese (Mn), a neurotoxicant at excessive concentrations was delivered through drinking water (0, 2, or 4 mg/mL) from gestational day (GD) 7 to postnatal day (PND) 22. A variable stress paradigm was applied to half of the animals from GD13 to PND9. Measurements of somatic development and behavior were examined in the offspring at different developmental stages. No evidence of overt maternal toxicity was observed although the 4 mg/mL Mn-exposed dams gained less body weight during gestation compared to the other dams. Stress also reduced gestational maternal weight gain. Daily fluid consumption normalized for body weight was decreased in the Mn-exposed dams in a dose-dependent manner but was not altered by the stress paradigm. Maternal stress and/or Mn exposure did not affect litter size or viability, but pup weight was significantly reduced in the 4 mg/mL Mn-exposed groups on PNDs 9 through 34 when compared to the other offspring groups. The efficacy of the manipulations to increase maternal stress levels was determined using serum corticosterone as a biomarker. The baseline concentration was established prior to treatment (GD7) and levels were low and similar in all treatment groups. Corticosterone levels were elevated in the perinatal-stress groups compared to the no-stress groups, regardless of Mn exposure, on subsequent time points (GD16, PND9), but were only significantly different on GD16. An analysis of tissue concentrations revealed Mn was elevated similarly in the brain and blood of offspring at PND2 and at PND22 in a significant dose-dependent pattern. Dams also showed a dose-dependent increase in Mn concentrations in the brain and blood; the addition of stress increased the Mn concentrations in the maternal blood but not the brain. Perinatal stress did not alter the effects of Mn on the maternal or offspring somatic endpoints described here.

Abstract
Background: Whilst the terms vulnerability and resilience are commonly used within professional nursing discourses, they are often poorly understood. Vulnerability is often framed negatively and linked to being at risk of harm, whilst resilience is often perceived as the ability to withstand challenges. Aim: The aim of this paper is to explore resilience and vulnerability; re-positioning them within the context of contemporary professional nursing practice. Design: Discussion paper. Method: Drawing upon historical and contemporary international literature, both concepts are de-constructed and then re-constructed, examining them from the position of patient care as well as from the perspective of nurses and the nursing profession. Conclusion: Resilience and vulnerability have an interdependent relationship as resilience comes into play in situations of vulnerability. Yet, contrary to the popular discourse they are multi-faceted, complex phenomena based on factors such as individual circumstances, supports, and resources.

BMC Health Serv Res 2018; 18:432. [PMID: 29884178 PMCID: PMC5994004 DOI: 10.1186/s12913-018-3243-2] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2018] [Accepted: 05/28/2018] [Indexed: 11/10/2022] Open
Abstract
Background Children born in families with non-medical risk factors, such as deprivation, have higher odds of preterm birth (< 37 weeks of gestation) or being born small for gestational age (birth weight < 10th percentile). In addition, growing up they are at risk for growth and developmental problems. Preventive Child Healthcare (PCHC) monitors growth and development of babies and children. Early identification of children at risk could result in early interventions to prevent growth and developmental problems in later life. Therefore, we aimed to assess current practices in postnatal risk screening and care for non-medical risk factors and the collaboration with other healthcare professionals, in both deprived and non-deprived neighbourhoods in the Netherlands. Methods Eight out of ten invited PCHC organisations, from different areas in the Netherlands, consented to participate in this study. A questionnaire was designed and digitally distributed to professionals working at these organisations, where 370 physicians and nurses were employed. Data was collected between June and September 2016. Descriptive statistics, chi square tests and t-tests were applied. Results Eighty-nine questionnaires were eligible for analyses. Twenty percent of the respondents were working in a deprived neighbourhood and 70.8% of the respondents were employed as nurse. Most of them performed screening for non-medical risk factors in at least 50% of their consultations. PCHC professionals working in deprived neighbourhoods encountered significantly more often families with non-medical risk factors and experienced significantly more communication problems than their colleagues working in non-deprived neighbourhoods. 48.2% of the respondents were satisfied with the current form of postnatal risk screening in their organisation, whereas 41.2% felt a need for a structured postnatal risk assessment. Intensified collaboration is preferred with district-teams, general practitioners and midwifes, concerning clients with non-medical risk factors. Conclusion This study shows that postnatal screening for non-medical risk factors is part of current PCHC practice, regardless the neighbourhood status they are deployed. PCHC professionals consider screening for non-medical risk factors as their responsibility. Consequently, they felt a need for a structured postnatal risk assessment and for an intensified collaboration with other healthcare professionals.

Abstract
Research has demonstrated that inequitable access to green space can relate to health disparities or inequalities. This commentary aims to shift the dialogue to initiatives that have integrated green spaces in projects that may promote health equity in the United States. Specifically, we connect this topic to factors such as community revitalization, affordable housing, neighborhood walkability, food security, job creation, and youth engagement. We provide a synopsis of locations and initiatives in different phases of development along with characteristics to support effectiveness and strategies to overcome challenges. The projects cover locations such as Atlanta (GA), Los Angeles (CA), the District of Columbia (Washington D.C.), South Bronx (NY), and Utica (NY). Such insight can develop our understanding of green space projects that support health equity and inform the dialogue on this topic in ways that advance research and advocacy.

Abstract
The Developmental Origins of Health and Disease and the related science of epigenetics redefines the meaning of what constitutes upstream approaches to significant social and public health problems. An increasingly frequent concept being expressed is "When it comes to your health, your zip code may be more important than your genetic code". Epigenetics explains how the environment-our zip code-literally gets under our skin, creates biological changes that increase our vulnerability for disease, and even children's prospects for social success, over their life course and into future generations. This science requires us to rethink where disease comes from and the best way to promote health. It identifies the most fundamental social equity issue in our society: that initial social and biological disadvantage, established even prior to birth, and linked to the social experience of prior generations, is made worse by adverse environments throughout the life course. But at the same time, it provides hope because it tells us that a concerted focus on using public policy to improve our social, physical, and economic environments can ultimately change our biology and the trajectory of health and social success into future generations.

Abstract
BACKGROUND Trauma is an innately subjective experience ensuing from a deeply distressing event. Research has demonstrated that while the environment of the neonatal intensive care unit (NICU) is capable of providing extraordinary lifesaving measures following birth, the experience may be disruptive to several key aspects of early development, placing infants at risk for adverse behavioral, cognitive, and emotional outcomes. PURPOSE This article provides rationale for the concept of Infant Medical Trauma in the NICU (IMTN) as a means of describing this unique stress experience. A triad of cumulative early life NICU experiences (stress, parental separation, and pain) is proposed to influence an infant's swinging neurodevelopmental pendulum amid the potential outcomes of risk and resilience. IMPLICATIONS FOR PRACTICE AND RESEARCH Creating language that describes the infant experience brings meaning and calls caregivers and parents to action to consider strategies that may improve long-term health. Actively seeking opportunities to decrease the allostatic load of at-risk infants may support an infant's pendulum to swing toward a path of resilience, thereby moderating his or her early life adverse experience.

Abstract
Evolving research in epigenetics and the developmental origins of health and disease offers tremendous promise in explaining how the social environment, place, and resources available to us have enduring effects on our health. Troubling from a communications perspective, however, is the tendency in framing the science to hold mothers almost uniquely culpable for their offspring's later disease risk. The purpose of this article is to add to the conversation about avoiding this unintended outcome by (1) discussing the importance of cognitive processing and issue frames, (2) describing framing challenges associated with communicating about developmental origins of health and disease and offering principles to address them, and (3) providing examples of conceptual metaphors that may be helpful in telling this complex and contextual story for public health.

Abstract
Identity research indicates that development of well elaborated cognitions about oneself in the future, or one's possible selves, is consequential for youths' developmental trajectories, influencing a range of social, health, and educational outcomes. Although the theory of possible selves considers the role of social contexts in identity development, the potential influence of the physical environment is understudied. At the same time, a growing body of work spanning multiple disciplines points to the salience of place, or the meaningful physical environments of people's everyday lives, as an active contributor to self-identity. Bridging these two lines of inquiry, I provide evidence to show how place-based experiences, such as belonging, aversion, and entrapment, may be internalized and encoded into possible selves, thus producing emplaced future self-concept. I suggest that for young people, visioning self in the future is inextricably bound with place; place is an active contributor both in the present development of future self-concept and in enabling young people to envision different future possible places. Implications for practice and future research include place-making interventions and conceptualizing place beyond "neighborhood effects."

Abstract
OBJECTIVES Early childhood development strongly influences lifelong health. The Early Development Instrument (EDI) is a well-validated population-level measure of five developmental domains (physical health and well-being, social competence, emotional maturity, language and cognitive skills, and communication skills and general knowledge) at school entry age. The aim of this study was to explore the potential of EDI as an indicator of early development in Ireland. DESIGN A cross-sectional design was used. SETTING The study was conducted in 42 of 47 primary schools in a major Irish urban centre. PARTICIPANTS EDI (teacher completed) scores were calculated for 1243 children in their first year of full-time education. Contextual data from a subset of 865 children were collected using a parental questionnaire. PRIMARY AND SECONDARY OUTCOME MEASURES Children scoring in the lowest 10% of the population in one or more domains were deemed 'developmentally vulnerable'. Scores were correlated with contextual data from the parental questionnaire. RESULTS In the sample population, 29% of children were not developmentally ready to engage in school. Factors associated with increased risk of vulnerability were being male OR 2.1 (CI 1.6 to 2.7); under 5 years OR 1.5 (CI 1.1 to 2.1) and having English as a second language OR 3.7 (CI 2.6 to 5.2). Adjusted for these demographics, low birth weight, poor parent/child interaction and mother's lower level of education showed the most significant ORs for developmental vulnerability. Calculating population attributable fractions, the greatest population-level risk factors were being male (35%), mother's education (27%) and having English as a second language (12%). CONCLUSIONS The EDI and linked parental questionnaires are promising indicators of the extent, distribution and determinants of developmental vulnerability among children in their first year of primary school in Ireland.

Abstract
Background Adolescence is characterized by marked psychosocial, behavioural and biological changes and represents a critical life transition through which adult health and well-being are established. Substantial research confirms the role of psycho-social and environmental influences on this transition, but objective research examining the role of puberty hormones, testosterone in males and oestradiol in females (as biomarkers of puberty) on adolescent events is lacking. Neither has the tempo of puberty, the time from onset to completion of puberty within an individual been studied, nor the interaction between age of onset and tempo. This study has been designed to provide evidence on the relationship between reproductive hormones and the tempo of their rise to adult levels, and adolescent behaviour, health and wellbeing. Methods/Design The ARCHER study is a multidisciplinary, prospective, longitudinal cohort study in 400 adolescents to be conducted in two centres in regional Australia in the State of New South Wales. The overall aim is to determine how changes over time in puberty hormones independently affect the study endpoints which describe universal and risk behaviours, mental health and physical status in adolescents. Recruitment will commence in school grades 5, 6 and 7 (10–12 years of age). Data collection includes participant and parent questionnaires, anthropometry, blood and urine collection and geocoding. Data analysis will include testing the reliability and validity of the chosen measures of puberty for subsequent statistical modeling to assess the impact over time of tempo and onset of puberty (and their interaction) and mean-level repeated measures analyses to explore for significant upward and downward shifts on target outcomes as a function of main effects. Discussion The strengths of this study include enrollment starting in the earliest stages of puberty, the use of frequent urine samples in addition to annual blood samples to measure puberty hormones, and the simultaneous use of parental questionnaires.

Abstract
OBJECTIVE Discrimination may contribute to health disparities among older adults. Existing measures of perceived discrimination have provided important insights but may have limitations when used in studies of older adults. This article illustrates the process of assessing the appropriateness of existing measures for theory-based research on perceived discrimination and health. METHOD First, we describe three theoretical frameworks that are relevant to the study of perceived discrimination and health-stress-process models, life course models, and the Public Health Critical Race (PHCR) praxis. We then review four widely-used measures of discrimination, comparing their content and describing how well they address key aspects of each framework, and discussing potential areas of modification. DISCUSSION Using theory to guide measure selection can help improve understanding of how perceived discrimination may contribute to racial/ethnic health disparities among older adults.

Abstract
Purpose. Explore the importance of residential mobility and use of services outside neighborhoods when interventions targeting low-income families are planned and implemented. Design. Analysis of cross-sectional telephone household survey data on childhood mobility and school enrollment in four large distressed cities. Setting. Baltimore, Maryland; Detroit, Michigan; Philadelphia, Pennsylvania; and Richmond, Virginia. Subjects. Total of 1723 teens aged 10 to 18 years and their parents. Measures. Continuous self-report of the number of years parents lived in the neighborhood of residence and city; self-report of whether the child attends school in their neighborhood; and categorical self report of parents' marital status, mother's education, parent race, family income, child's age, and child's sex. Analysis. Chi-square and multivariate logistic regression. Results. In this sample, 85.2% of teens reported living in the city where they were born. However, only 44.4% of black teens lived in neighborhoods where they were born, compared with 59.2% of white teens. Although 50.3% of black teens attended schools outside of their current neighborhoods, only 31.4% of whites did. Residential mobility was more common among black than white children (odds ratio = 1.82; p < .001), and black teens had 43% lesser odds of attending school in their home communities. Conclusions. Mobility among low-income and minority families challenges some assumptions of neighborhood interventions premised on years of exposure to enriched services and changes in the built environment.

A transdisciplinary perspective of chronic stress in relation to psychopathology throughout life span development. Dev Psychopathol 2011; 23:725-76.

Abstract
AbstractThe allostatic load (AL) model represents an interdisciplinary approach to comprehensively conceptualize and quantify chronic stress in relation to pathologies throughout the life cycle. This article first reviews the AL model, followed by interactions among early adversity, genetics, environmental toxins, as well as distinctions among sex, gender, and sex hormones as integral antecedents of AL. We next explore perspectives on severe mental illness, dementia, and caregiving as unique human models of AL that merit future investigations in the field of developmental psychopathology. A complimenting transdisciplinary perspective is applied throughout, whereby we argue that the AL model goes beyond traditional stress–disease theories toward the advancement of person-centered research and practice that promote not only physical health but also mental health.

Abstract
Group disparities in health have been documented for several decades. Despite recent efforts to eliminate them, group differences persist and challenge the ability of scientists to address them using traditional research paradigms. Because the determinants of disparities occur at multiple levels, from the molecular to the societal, and interact with one another in ways not yet fully understood, they represent a challenge to researchers attempting to capture their complexity. After reviewing existing models of disciplinary collaboration, we outline the challenges of a transdisciplinary approach and its ability to afford the holistic view of disparities needed to develop effective interventions.

Abstract
OBJECTIVE This study examined linkages between physical and psychological violence in childhood from parents and three dimensions of adult health (self-rated health, functional limitations, chronic conditions). METHODS Regression models were estimated using data from the 1995 and 2005 waves of the National Survey of Midlife in the U.S. Responses to an adapted version of the Conflict Tactics Scales in 1995 were used to code respondents into one of nine profiles of violence distinguished by types and frequency of violence. RESULTS Reports of both frequent physical and frequent psychological violence were associated with poorer health at baseline across the three dimensions of health, as well as with more severe declines in health across all three dimensions over the 10-year study period. DISCUSSION Results suggest that having experienced frequent physical and psychological violence in childhood is a risk factor for poorer adult health status and declining trajectories of health throughout adulthood.

Abstract
OBJECTIVE To examine if maltreatment predicted increased risk of hospital-based treatment prior to age 18 years for asthma, cardio-respiratory, and non-sexually transmitted infectious disease in a sample of low-income children. METHODS This study used administrative data from multiple systems to follow children for 12-18 years (N = 6,282). Cox regression was used to explore the risk of first hospital treatment by disease category. Negative binomial regression was used to explore the relationship between recurrent maltreatment and total hospital care episodes. RESULTS Controlling for individual, family, and community factors, children with maltreatment reports had a 74-100% higher risk of hospital treatment. Recurrent reports predicted a higher count of hospital care episodes. CONCLUSIONS The negative health impact of maltreatment prior to adulthood supports the need for early prevention and intervention to prevent initial and recurrent child abuse and improve capacity to meet healthcare needs of maltreated children.

Abstract
In the United States, despite substantial investment in public health initiatives to promote early detection of breast cancer through screening mammography, the proportion of female breast cancers that have advanced beyond the localized stage by the time of diagnosis remains high. Our objective in this exploratory study was to investigate whether stage of breast cancer at diagnosis among Chicago residents is associated with characteristics of the neighborhoods in which proximate mammography facilities are located. Those characteristics may influence likelihood of utilizing the service routinely and partly explain differences in stage at diagnosis. We used a retrospective cohort design and combined 3 years of data from the Illinois State Cancer Registry (ISCR) with information on locations of mammography facilities, public transportation service, crime, and area demographic and economic characteristics. Using a Geographic Information System (GIS), we identified the five facilities located nearest to each case's residence. Estimates of the association between characteristics of mammography facility locations and breast cancer stage at diagnosis were obtained using the partial proportional odds regression model. We found that the number of homicides in areas in which the nearest mammography facilities were located was associated with increased odds of later stage diagnosis. This effect was independent of age, race, and residential area education and income. We found no effect on stage of distance, public transportation service, or measures of neighborhood social similarity. The "spatial dynamics" of health may involve geographies beyond the immediate neighborhood. The results of our study suggest that areas in which the nearest mammography facilities are located may be one such geography. We hope that this study will spark research interest in the impact of health service locations on utilization.

Abstract
Because of a strong tendency to "medicalize" health status problems and to assume that their primary solution involves medical care, policymakers often focus on increased financial and geographic access to personal health services in policies aimed at populations that are vulnerable to poor health. This approach has produced real public health gains, but it has neglected key social and economic causes of health vulnerability and disparities. Although access to care is a necessary component of population health, concerted policy action in income security, education, housing, nutrition/food security, and the environment is also critical in efforts to improve health among socially disadvantaged populations.

Abstract
Today's widespread political support for the Genetic Information Nondiscrimination Act of 2007 rests on the assumption that serious inequities can be eliminated if employers are forbidden from using people's genetic information when making employment decisions. However, this laudable objective runs into serious weaknesses in implementation. Forcing employers to bear the cost of achieving parity between genetically high-risk and low-risk workers will create labor-market distortions that will inevitably shrink insurance coverage for vulnerable populations with genetic abnormalities along with everyone else. A better approach would be to create a politically transparent system of government-provided subsidies.
