Prophecies of childhood: how children's social environments and biological propensities affect the health of populations

The Long-Term Effects of Living in a Shared and Continuous Traumatic Reality: The Case of Israeli Families on the Border With Gaza

This article presents a literature review of the concept of intergenerational transmission of traumatic stress among a specific population of Israeli parents and children living near the Israeli/Gaza border, an area that can essentially be viewed as a laboratory of shared, continuous, and stressful reality resulting from ongoing political violence. The Google Scholar database was used to search only for peer-reviewed articles written in English and published between 2002 and 2020, and the particular focus of the study was Israeli families living in the "Gaza envelope": communities that have been on the receiving end of rockets and mortars from Gaza for the past 20 years. The review was based on 35 articles and sheds light on the existence of studies using a variety of perspectives (e.g., psychological, biopsychosocial, and behavioral). Findings demonstrate the effects of continuous stress situations on the family dynamic, even before birth, among this small population. In addition, they show that to understand the unique process of intergenerational trauma transmission in a shared continuous traumatic reality, it is important to adopt a comprehensive perspective so as to understand the reciprocal, long-lasting, and transgenerational effects of being exposed to traumatic stress. This perspective can be used as a basis for developing family intervention strategies that are appropriate for preventing stress outcomes that derive from living in the context of persistent violence.

Experience of children growing up with a parent who has military-related post-traumatic stress disorder: a qualitative systematic review

OBJECTIVE

The objective of this review is to describe the experiences of children growing up in military families whose parents have military-related post-traumatic stress disorder.

INTRODUCTION

Whether serving as a peacekeeper or warrior, military service is both physically and psychologically demanding, increasing exposures to potentially traumatic and morally injurious events and threats to personal safety. Those who have served in the military are at increased risk for developing post-traumatic stress disorder, which includes symptoms such as emotional numbing, withdrawal, and hyperarousal. Research has focused on the experiences of and impacts on spouses and partners of military veterans with post-traumatic stress disorder, with quantitative and synthesis studies reporting on measurable impacts on children growing up in military families where a parent is diagnosed with post-traumatic stress disorder.

INCLUSION CRITERIA

This review included children who are or have grown up in military families in domestically peaceful nations that deploy their armed forces to global locations of political instability, armed civil conflict, and/or natural disasters for the purposes of peacekeeping, humanitarian aid, or war, as well as parents living with post-traumatic stress disorder who speak specifically about the experience of their children. Situations of homeland conflict were excluded. The military families of interest are those with one or more parent having a diagnosis of post-traumatic stress disorder associated with military service. Traumatic experiences leading to post-traumatic stress disorder can be acquired prior to military service or through unrelated experiences, so it cannot be presumed that military service or even combat deployment, in and of itself, causes post-traumatic stress disorder. This review includes the experiences of children currently in childhood as well as adult children of a parent with current or previous military service.

METHODS

The following databases were first searched in August 2016 and updated in January 9, 2020: MEDLINE, Embase, Web of Science Core Collection, CINAHL, PsycINFO, AMED, ERIC, and ProQuest Dissertations and Theses Global. This review was conducted in accordance with JBI methodology for systematic reviews of qualitative evidence and with an a priori protocol published in 2018.

RESULTS

Twelve studies were included. The majority of the studies were published after 2006. The review represents the experiences of 139 children (n = 66) and adult children (n = 73) participants from military families in the United States, Canada, and Australia. There were four synthesized findings: i) Parental post-traumatic stress disorder creates a volatile and distressing climate within the family, eliciting a range of responses from children (86 findings across three categories); ii) Parental post-traumatic stress disorder ripples through the family system, disrupting interpersonal communication and relationships during childhood (57 findings over four categories); iii) Children can experience emotional and psychological difficulties well into adulthood (84 findings across five categories); and iv) Making sense of it all and moving beyond parental post-traumatic stress disorder can take significant time, energy, and support (74 findings across four categories).

CONCLUSIONS

The quality of the included studies proved to be high, giving strength to this review. Effective ways of communicating with children about the nature of both the traumatic exposure and the post-traumatic stress disorder itself must be developed. While individuals with post-traumatic stress disorder deserve appropriate interventions to alleviate symptoms and improve functioning, it is not sufficient for recovery from post-traumatic stress disorder either for the individual or for the family who has been deeply affected themselves. Prospective and longitudinal research is needed, ensuring that both the voice of the child and multiple perspectives within family systems are included and compared.

Hair cortisol in mother-child dyads: examining the roles of maternal parenting and stress in the context of early childhood adversity

Physiological stress is thought to be one way that early adversity may impact children's health. How this occurs may be related to parental factors such as mothers' own stress and parenting behaviour. Hair cortisol offers a novel method for examining long-term physiological stress in mother-child dyads. The current study used hair cortisol to examine the role that maternal physiological stress and parenting behaviours play in explaining any effects of adversity on young children's physiological stress. This cross-sectional study comprised 603 mother-child dyads at child age 2 years, recruited during pregnancy for their experience of adversity through an Australian nurse home visiting trial. Hair cortisol data were available for 438 participating mothers (73%) and 319 (53%) children. Confirmatory factor analysis was used to define composite exposures of economic (e.g. unemployment, financial hardship) and psychosocial (e.g. poor mental health, family violence) adversity, and positive maternal parenting behaviour (e.g. warm, responsive). Structural equation modelling examined maternal mediating pathways through which adversity was associated with children's physiological stress. Results of the structural model showed that higher maternal and child physiological stress (hair cortisol) were positively associated with one another. Parenting behaviour was not associated with children's physiological stress. There was no evidence of any mediating pathways by which economic or psychosocial adversity were associated with children's physiological stress. The independent association identified between maternal and child hair cortisol suggests that young children's physiological stress may not be determined by exogenous environmental exposures; endogenous genetic factors may play a greater role.

"In the Clinic They Know Us": Preferences for Clinic-Based Financial and Employment Services in Urban Pediatric Primary Care

OBJECTIVE

To understand views of adolescent and adult caregivers on integrating employment and financial services into a pediatric primary care clinic serving low-income families.

METHODS

Eighteen in-depth qualitative interviews were conducted among caregivers of pediatric patients. Participants were recruited from those who completed a survey assessing financial and employment needs. Audio-recorded transcripts were analyzed using line-by-line coding of emerging themes.

RESULTS

Adolescent and adult caregivers expressed difficulty managing financial stress. They cited having a criminal history, limited financial literacy, and lack of available quality jobs as barriers to achieving financial stability. A clinic-based employment and financial program was highly acceptable among potential users for the convenience it offers and the established trust and understanding between patients and clinical providers. Participants preferred one-on-one counseling for sensitive employment and financial issues, although they did believe that some topics, such as building a resume, could be accomplished in group workshops.

CONCLUSIONS

Caregivers attending a pediatric clinic expressed interest in and anticipated value from clinic-based employment and financial services if implemented services are relevant, accessible, and provide options for group and individualized approaches.

Experiences of children exposed to parental post-traumatic stress disorder while growing up in military and veteran families: a systematic review protocol

REVIEW QUESTION/OBJECTIVE

The objective of this review is to understand how parental Post-Traumatic Stress Disorder (PTSD) might impact children growing up in military and veteran families. The following question will guide and inform the review: What is the experience of children growing up in military families where the military or veteran parent is living with post-traumatic stress disorder?

Adverse Housing Conditions and Early-Onset Delinquency

Housing constitutes an important health resource for children. Research has revealed that, when housing conditions are unfavorable, they can interfere with child health, academic performance, and cognition. Little to no research, however, has considered whether adverse housing conditions and early-onset delinquency are significantly associated with one another. This study explores the associations between structural and non-structural housing conditions and delinquent involvement during childhood. Data from the Fragile Families and Child Wellbeing Study (FFCWS) were employed in this study. Each adverse housing condition was significantly associated with early-onset delinquency. Even so, disarray and deterioration were only significantly linked to early delinquent involvement in the presence of health/safety hazards. The predicted probability of early-onset delinquency among children exposed to housing risks in the presence of health/safety hazards was nearly three times as large as the predicted probability of early-onset delinquency among children exposed only to disarray and/or deterioration, and nearly four times as large as the predicted probability of early-onset delinquency among children exposed to none of the adverse housing conditions. The findings suggest that minimizing housing-related health/safety hazards among at-risk subsets of the population may help to alleviate other important public health concerns-particularly early-onset delinquency. Addressing household health/safety hazards may represent a fruitful avenue for public health programs aimed at the prevention of early-onset delinquency.

Socioeconomic status inequalities in low-grade inflammation during childhood

BACKGROUND

Family socioeconomic status (SES) is an important source of child health disparities in the USA. Chronic stress is one way SES may impact children's physiology with implications for later health inequalities. These processes may work differently across childhood due to differences in exposure and susceptibility to stressors at different ages. We assess associations between family SES and one biomarker of chronic stress exposure-low-grade inflammation detected by elevated C reactive protein (CRP)-and evaluate differences in the associations by child age.

METHODS

We used nationally representative data from the National Health and Nutrition Examination Survey and Tobit regression models to estimate SES associations with CRP and the moderating effects of age for children age 2-18 years. Our sample was limited to CRP ≤10 mg/l to focus on low-grade inflammation (N=13 165).

RESULTS

Children whose parent had less than a high school degree had 35% higher CRP than those with a college graduate parent; and, poor children had 24% higher CRP than those with high family income, net of controls. When children's body mass index was accounted for, low education and poverty associations were reduced to 19% and 15%, respectively. Child age interactions were negative and significant for both parental education and family income.

CONCLUSIONS

This study provides new evidence that SES is associated with low-grade inflammation in children, and that these associations may be particularly strong during early and mid-childhood. Future research should further our understanding of stressors related to low family SES that may lead to immune system dysregulation during childhood.

Home sweet home? Home physical environment and inflammation in children

The home environment includes important social and physical contexts within which children develop. Poor physical home environments may be a potential source of stress for children through difficult daily experiences. Using a sub-sample from the Los Angeles Family and Neighborhood Survey (N = 425), we consider how the home physical environment affects stress-related immune system dysregulation in children ages 3-18 years. Results indicated that children in poorer quality homes had higher inflammation (measured by C-reactive protein). The associations were particularly strong for younger children. We also found that part of the home physical environment association with CRP worked through increased risk of obesity for children living in low-quality homes. Future research should assess how home physical environments could be improved to reduce stress and improve health outcomes in children.

Parental stress increases body mass index trajectory in pre-adolescents

WHAT IS ALREADY KNOWN ABOUT THIS SUBJECT

Rates of childhood obesity have increased since the mid-1970s. Research into behavioural determinants has focused on physical inactivity and unhealthy diets. Cross-sectional studies indicate an association between psychological stress experienced by parents and obesity in pre-adolescents.

WHAT THIS STUDY ADDS

We provide evidence of a prospective association between parental psychological stress and increased weight gain in pre-adolescents. Family-level support for those experiencing chronic stress might help promote healthy diet and exercise behaviours in children.

OBJECTIVE

We examined the impact of parental psychological stress on body mass index (BMI) in pre-adolescent children over 4 years of follow-up.

METHODS

We included 4078 children aged 5-10 years (90% were between 5.5 and 7.5 years) at study entry (2002-2003) in the Children's Health Study, a prospective cohort study in southern California. A multi-level linear model simultaneously examined the effect of parental stress at study entry on the attained BMI at age 10 and the slope of change across annual measures of BMI during follow-up, controlled for the child's age and sex. BMI was calculated based on objective measurements of height and weight by trained technicians following a standardized procedure.

RESULTS

A two standard deviation increase in parental stress at study entry was associated with an increase in predicted BMI attained by age 10 of 0.287 kg m(-2) (95% confidence interval 0.016-0.558; a 2% increase at this age for a participant of average attained BMI). The same increase in parental stress was also associated with an increased trajectory of weight gain over follow-up, with the slope of change in BMI increased by 0.054 kg m(-2) (95% confidence interval 0.007-0.100; a 7% increase in the slope of change for a participant of average BMI trajectory).

CONCLUSIONS

We prospectively demonstrated a small effect of parental stress on BMI at age 10 and weight gain earlier in life than reported previously. Interventions to address the burden of childhood obesity should address the role of parental stress in children.

Reflections on the interaction of psychogenic stress systems in humans: the stress coherence/compensation model

Although stress simultaneously affects and causes changes in central nervous system systems together with the sympathetic nervous system and the hypothalamus-pituitary-adrenal axis, this interaction and its behavioral consequences are rarely assessed. The current paper first describes the different systems involved in the perception and processing of stressful stimuli on an anatomical and functional level, and the available measures to assess changes in these systems. It then explores, based on theoretical and empirical grounds, the interaction of the systems. This is followed by a review of previous stress models, and how these attempted to integrate the interaction of these systems. Then, it complements previous models by suggesting a complementary regulation of the stress systems, and discusses potential behavioral consequences. Finally, based on the three-system approach to assess stress it is argued that psychological measures, together with physiological and endocrine measures are indispensable. However, the lack of consensus on how to best assess the central and sympathetic nervous system components of stress make it more difficult to include measures of all systems routinely in future stress studies. Thus, the paper closes by giving some recommendations on how to include a minimum of feasible stress measures for all systems involved in stress processing and regulation.

A transdisciplinary perspective of chronic stress in relation to psychopathology throughout life span development

The 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.

Linking psychosocial stressors and childhood obesity

Research has established a wide array of genetic and environmental factors that are associated with childhood obesity. The focus of this review is on recent work that has established the relationship between one set of environmental factors, stressors and childhood obesity. These stressors are particularly prevalent for low-income children, a demographic group that has high rates of obesity in the USA and other developed countries. In this review, we begin by summarizing the psychosocial stressors faced by children followed by health outcomes associated with exposure to these stressors documented in the literature. We then summarize 11 articles which examined the connection between psychosocial stressors in the household and obesity and eight articles which examined the connection between individual psychosocial stressors and obesity. Policy recommendations emerging from this research include recognizing reductions in childhood obesity as a potential added benefit of social safety net programmes that reduce financial stress among families. In addition, policies and programmes geared towards childhood obesity prevention should focus on helping children build resources and capacities to teach them how to cope effectively with stressor exposure. We conclude with suggestions for future research.

Monitoring inequities in self-rated health over the life course in population surveillance systems

OBJECTIVES

To investigate the effect of social mobility and to assess the use of socioeconomic indicators in monitoring health inequities over time, we examined the association of self-rated health with socioeconomic position over the life course.

METHODS

Data came from a cross-sectional telephone survey (n = 2999) that included life-course socioeconomic indicators and from a chronic disease and risk factor surveillance system (n = 26 400). Social mobility variables, each with 4 possible intergenerational trajectories, were constructed from family financial situation and housing tenure during childhood and adulthood.

RESULTS

Low socioeconomic position during both childhood and adulthood and improved financial situation in adulthood were associated with a reduced prevalence of excellent or very good health. Trends over time indicated that socioeconomic disadvantage in adulthood was associated with poorer self-rated health.

CONCLUSIONS

Our results support policies aiming to improve family financial situation during childhood and housing tenure across the life course. Inclusion of life-course socioeconomic measures in surveillance systems would enable monitoring of health inequities trends among socially mobile groups.

Does height modify the risk of angina associated with economic adversity?

Adult height partly reflects childhood exposures, and we hypothesise that some exposures impairing growth may also increase susceptibility to coronary heart disease--angina pectoris (angina)--risks, such that shorter adults may be more susceptible to some exposures in adulthood that are risks for heart disease. This hypothesis is tested among all adults who participated in the National Health Interview Survey (USA), 1997-2000 [The National Health Survey, 1997-2000. Data file documentation, National Health Interview Survey (machine-readable data file and documentation). National Center for Health Statistics, Hyattsville, Maryland, ]. In the entire study population, height was negatively associated with angina and after adjustment for potential confounding factors; the odds ratio (and 95% confidence interval) for angina risk associated with the tallest height fifth compared with the shortest fifth is 0.77 (0.97, 0.88). The association of low income (less than US 20,000 dollars) with angina was assessed separately in each of five height strata defined by fifths of the height distribution. The magnitude of this association is lower in the shortest than the tallest height fifth, with odds ratios of 1.18 and 1.60, respectively (effect modification). The unexpected results may be explained by the following: childhood adversity resulting in shorter stature may confer resilience against adult economic adversity; the relative disadvantage of low income may be perceived more keenly by those of taller stature thereby increasing stress and thus disease risk; or health-promoting characteristics associated with taller stature may be less effective in the face of adult economic adversity in the low-income group.

Anxiety and depression in fathers in teenage pregnancy

OBJECTIVE

It is recognized that pregnant teenagers have higher levels of psychological symptomatology compared to older pregnant women. However, there are limited data on fathers in the setting of teenage pregnancy. The aim of this study was to compare levels of psychological symptomatology in fathers in the setting of teenage as compared to non-teenage pregnancy.

METHOD

A cross-sectional cohort study was undertaken. Data from interviews with consecutive fathers in the setting of teenage (Teenage) and non-teenage (Control) pregnancy were compared during the antenatal period. Subjects were interviewed to obtain information covering demographic and family information, the Hospital Anxiety and Depression Scale (HADS) and General Health Questionnaire-28 (GHQ-28).

RESULTS

Significantly more fathers in the setting of teenage pregnancy met the case criteria for HADS-A and HADS-D subscales compared to older fathers. They had significantly higher GHQ-28 totals and all subscale scores and were more likely predictive of a young age of death compared to older fathers. However, formal contact with psychiatric services was similar between groups. Interestingly, 14% of fathers in the setting of teenage pregnancy reported losing their own father as a child. In multivariate analysis, a high HADS score was significantly associated with younger age of onset of fatherhood and exposure to domestic violence as a child, whereas having their own father alive was significantly protective against a high HADS score.

CONCLUSION

Fathers, in the setting of teenage pregnancy, have unrecognized psychological symptomatology and require services along with teenage mothers.
