Children's diurnal cortisol output and temperament in two different childcare settings at 2 and 3.5 years of age.

Prior research suggests that child temperament may play an important role in early childhood stress regulation. We compared children's diurnal cortisol and the association between cortisol and temperament in two different childcare settings. Cortisol was measured from saliva samples over 2 days in children (N=84) attending out-of-home childcare and in children (N=27), who were cared for at home at the age of 3.5 years. There was no difference between the childcare groups in total diurnal cortisol. However, of the individual measurements, afternoon cortisol levels were higher in the out-of-home childcare group during their childcare day when compared with their home day. Child temperament was not associated with total diurnal cortisol. Comparison with our prior measurements showed that the association between temperamental surgency/extroversion and total diurnal cortisol diminished along with the child age from 2 to 3.5 years in both childcare settings. This may indicate that more extroverted children are physiologically more reactive to environmental stimuli when they are younger, but this association does not appear as the children develop. Our results further suggest that the afternoon hours in the out-of-home childcare may be demanding and accelerate the hypothalamus-pituitary-adrenal axis activation in young children independent of their age.

From early to late modern societies (late 16th - early 20th century): Shifts in dental health status in two populations from southeastern France

In France, bioarcheological research has long overlooked the early and late modern periods, which witnessed major transformations impacting population structure and leading to the dawn of modern industrialized societies. Two recently excavated large cemeteries in Provence present a unique opportunity to investigate on a large scale the impact on health and living conditions brought about by the Industrial Revolution and consequently track health status changes from the 16th to the early 20th century.The sample includes 642 individuals from the early modern cemetery of Saint-Jacques, La Ciotat (1581–1831) and the late modern cemetery of Les Crottes, Marseille (1784–1905). This study aims to document dental health markers and compare the results between both assemblages, considering ante-mortem tooth loss, wear, caries, abscesses, calculus, periodontitis and linear enamel hypoplasia. The available archaeological and historical sources for these recent periods provide a full documentation in which to interpret and discuss the biological analysis, thus enabling an inclusive bioarcheological approach. Resultsrevealed similarities between both samples. Differences are more subtle than expected and are seen through the increase in carious lesions and in linear enamel hypoplasia. The former seem to indicate changes in diet with the introduction of new foodstuffs and manufacturing processes during the Industrial Revolution. The latter could reflect the increase in early childhood stress, perhaps due to new feeding practices around weaning and breastfeeding or a poorly diversified diet. Finally, the increasing number of stress events could suggest a noxious sanitary and infectious environment. During the 19th century, Marseille experienced strong demographic and urban growth, resulting in overcrowded areas where sanitation facilities were insufficient or absent. Moreover, the activity of this important trading seaport might have promoted the transmission and appearance of epidemic diseases despite scientific and medical advances, which would have a real impact only from the 20th century onwards.

The Effects of Early Childhood Stress on Mortality under Neolithization in the Levant

Abstract. This study investigates the causal relationships among early-life health conditions, mortality across the lifespan, and population growth during neolithization in the Levant. We analyze a comprehensive sample of 558 human skeletons, associated with mortuary features from 24 Levantine sites spanning the transition to agriculture, from the Early Natufian period to the Pre-Pottery Neolithic C (Southern Levant) and Pottery Neolithic periods (Northern Levant), mainly covering 13,000-6,000 BC. We find that early-life stress—as preserved in linear enamel hypoplasias (LEH) that we recorded in the study sample—not only increased dramatically in prevalence with the adoption of agriculture and village life. Early-life stress was also strongly associated with mortality in the juvenile, adolescent, and younger-adult life stages (ca. 5-29 years). This statistical link is independent of analysis of raw life-stage-at-death distributions, which may be heavily biased by ancient age or sex-skewed funerary recruitment practices. According to our results, biological well-being deteriorated with the adoption of agriculture and village life between ca. 9,000-6,000 BC. We find that the transition to agriculture raised risks for premature mortality across the Levant. We suggest that in the regional transition to agriculture, mortality and fertility rose together in a fragile dynamic, the balance of which may have shifted in the 7th millennium BC, as a rapid rise in early-life stress exposures reduced average well-being.

Associations Between Maternal Post-traumatic Stress Disorder and Traumatic Events With Child Psychopathology: Results From a Prospective Longitudinal Study.

Introduction: Exposure to interpersonal violence (IPV) can lead to post-traumatic stress disorder (PTSD) in mothers, and in turn adversely affect the mother-child relationship during early development, as well as the mental health of their children. Our objectives are to assess: (1) the association of maternal IPV-PTSD to child psychopathology, (2) the association of maternal IPV independently of PTSD to child psychopathology, and (3) the relationship between child exposure to violence to the psychopathology of these children.Methods: We used data from the longitudinal Geneva Early Childhood Stress Project. The sample included 64 children [mean age at Phase 1 = 2.4 (1.0–3.7) years] of mothers with or without IPV-PTSD. Data on mothers was collected during Phase 1, using the Clinical Administered PTSD Scale (CAPS), the Brief Physical and Sexual Abuse Questionnaire (BPSAQ) and the Conflict Tactics Scale (CTS2). Modules of a semi-structured diagnostic interview, and the Violence Exposure Scale were used to collect information on child at Phase 2, when children were older [mean age = 7.02 (4.7–10)].Results: A higher CAPS score in mothers when children were toddler-age was associated with an increased risk of symptoms of attention deficit/hyperactivity disorder (ADHD; β = 0.33, p = 0.014) and PTSD in school-age children. The association between maternal IPV-PTSD and child PTSD (β = 0.48, p < 0.001) symptoms remained significant after adjustment for potential confounders. Among children, exposure to violence was associated with an increased risk of symptoms of generalized anxiety (β = 0.37, p = 0.006), major depressive (β = 0.24, p = 0.039), ADHD (β = 0.27, p = 0.040), PTSD (β = 0.52, p < 0.001), conduct (β = 0.58, p = 0.003) and oppositional defiant (β = 0.34, p = 0.032) disorders.Conclusion: Our longitudinal findings suggest that maternal IPV-PTSD during the period of child development exert an influence on the development of psychopathology in school-aged children. Mothers' IPV was associated with child psychopathology, independently of PTSD. Child lifetime exposure to violence had an additional impact on the development of psychopathology. Careful evaluation of maternal life-events is essential during early childhood to reduce the risk for the development of child psychopathology. Early efforts to curb exposure to violence in children and early intervention are both needed to reduce further risk for intergenerational transmission of trauma, violence, and related psychopathology.

Early life stress and behavior problems in early childhood: Investigating the contributions of child temperament and executive functions to resilience.

This preregistered study examined whether child temperament and executive functions moderated the longitudinal association between early life stress (ELS) and behavior problems. In a Dutch population‐based cohort (n = 2803), parents reported on multiple stressors (age 0–6 years), child temperament (age 5), and executive functions (age 4), and teachers rated child internalizing and externalizing problems (age 7). Results showed that greater ELS was related to higher levels of internalizing and externalizing problems, with betas reflecting small effects. Lower surgency buffered the positive association of ELS with externalizing problems, while better shifting capacities weakened the positive association between ELS and internalizing problems. Other child characteristics did not act as moderators. Findings underscore the importance of examining multiple protective factors simultaneously.

Adverse childhood experiences and behavior problems among poor Black children: Nonresident father involvement and single mothers' parenting stress

BackgroundAdverse childhood experiences (ACEs) in early childhood and developmental outcomes during the middle childhood and adolescent years have been understudied among low-income Black families. ObjectiveTo test a model linking economic hardship, single mothers' parenting stress, ACEs, and nonresident fathers' involvement in early childhood to behavior problems in middle childhood and adolescence. Participants and settingWe used six waves of longitudinal data from a subsample of 800 unmarried Black mothers, nonresident fathers, and their children (at child birth and ages 1, 3, 5, 9, and 15) from the Fragile Families and Child Wellbeing Study, a nationally representative data set. MethodStructural equation models with latent variables that incorporate path analysis and confirmatory factor analysis were tested. ResultsMothers' economic hardship was associated directly with parenting stress (beta = 0.27, p < .001) and related both directly (beta = 0.22, p < .001) and indirectly (through parenting stress) to the children's increased likelihood of exposure to ACEs (indirect effect = 0.05, p < .001). Nonresident fathers' involvement early on (child's age 1 to 5) was associated directly with reductions in the mothers' economic hardship (beta = −0.18, p < .001), children's reduced exposure to ACEs (beta = −0.15, p < .001), and fewer behavior problems in middle childhood and adolescence (beta = −0.10, p < .001). ConclusionNonresident Black fathers' involvement in single-mother families may buffer the adverse consequences over time for economically and socially disadvantaged Black children of exposure to ACEs in early childhood. Interventions that encourage sustained involvement by nonresident Black fathers with young children and their single mothers are recommended.

The success of education lies in the extent to which teachers use their abilities in educational practice. This study aims to analyze the academic stress in early childhood in Kindergarten institutions in Banjaran District. The research uses a qualitative approach using the case study. The subject of this research is a Kindergarten teacher in Banjaran District. Collecting data using observation and interviews. Analysis of research data using grounded theory. Test the validity of research data using triangulation of sources and techniques. The results of this study indicate that early childhood experiences stress in Banjaran District due to pressure from parents or guardians of students who want their children to be able to reading, writing, and counting. Principals and teachers have to fulfill the demands of parents or guardians of Kindergarten students in Banjaran District. In addition, the Principal of Kindergarten Schools in Banjaran District assigns various tasks to teachers. The findings of this study contribute to knowledge in the form of causes of early childhood academic stress and recommend early childhood education institutions to minimize stress in early childhood.

Externalizing Behaviors are Associated with Increased Parenting Stress in Caregivers of Young Children with Autism.

Parents of children diagnosed with autism spectrum disorder (ASD) report higher levels of stress than parents of typically developing children. Few studies have examined factors associated with parental stress in early childhood. Even fewer have investigated the simultaneous influence of sociodemographic, clinical, and developmental variables on parental stress. We examined factors associated with stress in parents of young children with ASD. Multiple regression models were used to test for associations between socioeconomic indices, developmental measures, and parental stress. Externalizing behaviors, communication, and socialization skills accounted for variance in parental stress, controlling for ASD diagnosis. Results highlight the importance of interventions aimed at reducing externalizing behaviors in young children as well as addressing stress in caregivers of children with ASD.

Joint care of parents and infants in perinatal psychiatry

Abstract BodyIn the perinatal period, about 15-20 % of women will present a mental health disorder. These disorders, as with all sources of psychological and physical stress in early childhood, especially the poor quality of parent-child relationships, are widely involved in predicting poor mental health in adulthood. The economic cost of perinatal mental health, corollary of this human cost, evaluated in 2014 would amount to £GBP 8.1 billion per annual birth cohort according to a UK report. This report highlights another fundamental element: 3/4 of the costs are associated with the deleterious consequences of parental psychological disorders on child development. The mechanisms involved in the relationship between parental psychiatric disorders and child development are complex. On the other hand, the influence of parental characteristics on the future of children can vary depending on social determinants such as familial income level. During the perinatal period, parental mental health represents one of the keys to the infant development. Perinatal psychiatry allows a dual approach essential to deal with the complexity of perinatal psychiatry care, combining a curative aim (care of the parent) and a preventive one (preventing the risk of dysfunction in the process of becoming parents, in parent-child relationships and of impaired child developement). This intervention wil discuss how this interactive circle must be supported by perinatal mental health policies, of which the joint care of parents and infants (from parent-child psychotherapy to joint mother-baby hospitalisation) in perinatal psychiatry is a pivotal element.DisclosureNo significant relationships.

Mothers' Parenting Stress and Neighborhood Characteristics in Early Childhood (Ages 0-4).

Neighborhood characteristics are important when raising children. Traditional approaches to parental stress research have focused on the impacts of daily hassles and how individual factors, such as children’s temperament, family resources, and social support from friends and family reduce or exacerbate parental stress. There have been few studies on neighborhood characteristics and parental stress, and even fewer studies have examined the association longitudinally. The goal of the present study was to explore the association between mothers’ parental stress and neighborhood characteristics longitudinally across early childhood (ages 0–4). Using the 2008–2012 Panel Study on Korean Children, we followed 1536 mothers. The results showed that mothers’ parenting stress was highest when children were aged two to three, and neighborhood characteristics had significant associations with parenting stress. The study indicated that mothers who reported that their neighborhoods had sufficient childcare facilities, were convenient to access public recreational and cultural facilities, and those who reported that their neighborhoods were good places to raise children, exhibited significantly lower levels of parenting stress. Further, the effects of neighborhoods on mothers’ parenting stress were greatest when children were aged one and four. Hence, such findings should be incorporated when designing and developing communities.

Stress and Cardiometabolic Disease Risk for Indigenous Populations throughout the Lifespan.

Background: Indigenous people experience the greatest cardiometabolic disease disparity in the Unites States, yet high cardiometabolic disease risk factors do not fully explain the extent of the cardiometabolic disease disparity for Indigenous people. Stress, trauma, and racism occur at high rates within Indigenous communities and have not been well explored as significant contributors to cardiometabolic disease disparities despite emerging literature, and therefore will be described here. Methods: This descriptive study explores the relationship between cardiometabolic disease risks and Indigenous-specific stressors (e.g., early childhood stress and trauma, adulthood stress and trauma, and historical and intergenerational trauma) using current literature. Indigenous-specific protective factors against cardiometabolic disease are also reviewed. Results. Increasing research indicates that there is a relationship between Indigenous-specific stressful and traumatic life experiences and increased cardiometabolic disease risk. Mental health and psychophysiology play an important role in this relationship. Effective interventions to reduce cardiometabolic disease risk in Indigenous communities focus on ameliorating the negative effects of these stressors through the use of culturally specific health behaviors and activities. Conclusions: There is increasing evidence that cultural connection and enculturation are protective factors for cardiometabolic disease, and may be galvanized through Indigenous-led training, research, and policy change.

Early childhood stress is associated with blunted development of ventral tegmental area functional connectivity

Early life stress increases risk for later psychopathology, due in part to changes in dopaminergic brain systems that support reward processing and motivation. Work in animals has shown that early life stress has a profound impact on the ventral tegmental area (VTA), which provides dopamine to regions including nucleus accumbens (NAcc), anterior hippocampus, and medial prefrontal cortex (mPFC), with cascading effects over the course of development. However, little is known about how early stress exposure shifts the developmental trajectory of mesocorticolimbic circuitry in humans. In the current study, 88 four- to nine-year-old children participated in resting-state fMRI. Parents completed questionnaires on their children's chronic stress exposure, including socioeconomic status (SES) and adverse childhood experiences (ACEs). We found an age x SES interaction on VTA connectivity, such that children from higher SES backgrounds showed a positive relationship between age and VTA-mPFC connectivity. Similarly, we found an age x ACEs exposure interaction on VTA connectivity, such that children with no ACEs exposure showed a positive relationship between age and VTA-mPFC connectivity. Our findings suggest that early stress exposure relates to the blunted maturation of VTA connectivity in young children, which may lead to disrupted reward processing later in childhood and beyond.

Resilience: A Longitudinal Study of Children with Risk Factors

Resilience: A Longitudinal Study of Children with Risk Factors This study examines the development of children who have grown up with severe early childhood stress. A distinction was made between resilient and maladapted child developments. On the one hand, the aim was to identify longitudinal protective factors that can contribute to the development of resilience. On the other hand, we cross-sectionally examined in which psychological areas resilience manifests itself. The sample consists of 343 children who were examined first in early childhood (M = 4 years) and then ten years later in adolescence. 24 % of the children belonged to the risk group of which 14 % showed a resilient and 9 % a maladapted development. An active temperament, higher intelligence, and more self-control in early childhood proved to be protective factors with medium effect sizes. The proportion of resilience was increased among migrants. Cross-sectionally we found differences with small and medium effect sizes in addictive behavior (alcohol, tobacco and drug use), internet dependency, overweight, and school grades.

Self-Reported Psychosocial Stress in Parents With Small Children.

Psychosocial stress in early childhood can impair children's health and development. Data on the prevalence of psychosocial stress in families with infants and toddlers in Germany are lacking. Such data could be used to determine the need for prevention and to plan the appropriate preventive measures. In 2015, a representative cross-sectional study called Kinder in Deutschland- KiD 0-3 was conducted by questionnaire in pediatricians' practices across Germany. Parents taking their children to the U3-U7a child development checks were asked to self-report information about stress in their families. The data were analyzed with descriptive statistics and chi-square tests. Data from 7549 families went into the analysis. Stressful situations commonly reported by the parents included unplanned pregnancy (21.3%), parenthoodrelated stress (e.g., self-doubt as to parenting competence, 29.6%), and lack of familial and social support for problems and questions arising in relation to the child, as well as for temporary child care (19.7%). Most types of psychosocial stress varied as a function of the child's age group, as categorized by the particular examination for which the child was presenting at the time of the survey (U3-U7a). Couple distress, lack of social support, signs of depression or anxiety symptoms, or inner anger were more commonly reported by parents attending the later examina - tions. Such problems could be addressed by supportive measures (e.g., parent counseling, early child intervention). Psychosocial stress affects a large percentage of the parents of small children. A large proportion of parents of small children suffer from psychosocial stress. This should be monitored for accumulation and stability across child development checks and addressed as appropriate. Family practitioners and pediatricians are important partners for effective cooperation between the social system and the health-care system, and for the provision of preventive measures where appropriate.

Early life stress exposure associated with reduced polyunsaturated-containing lipids in low-income children.

Background:Psychosocial stress in early childhood is associated with adult obesity and cardiometabolic disease. The association of psychosocial stress with the metabolome in childhood is unknown.Method:Low-income children (n=28, mean age 1.8 years) recruited from the community, participated. Psychosocial stress was measured by diurnal salivary cortisol (cortisol intercept and slope) and by mother-reported chaos in the home using the Confusion, Hubbub, and Order Scale (CHAOS). At mean age 6.1 years, anthropometry was collected and fasting metabolites measured using an untargeted metabolomics and shotgun lipidomics platform.Results:Cortisol slope was inversely associated with fatty acid (FA) 20:3, FA 20:4 and polyunsaturated fatty acids (PUFA) metabolites. A higher CHAOS score was associated with lower very long-chain PUFA metabolites and a trend towards lower long-chain PUFA containing triglycerides.Conclusion:Psychosocial stress in early childhood, measured with both biological markers and parent report, was associated with lower PUFAs later in childhood. Future work should examine potential mechanisms of association, including dietary intake or direct effects on polyunsaturated fatty acid levels or metabolism.

Long-term consequences of aversive childhood experiences: effects on cerebral structures

Long-term consequences of aversive childhood experiences: effects on cerebral structures Abstract. Early childhood stress experiences due to neglect, and physical, psychological or sexual abuse can lead to permanent changes in central nervous structures. The central nervous system generally shows a very high plasticity in early childhood. Objectively, these influences are reflected in functional and structural-morphological changes in certain brain areas. Subjectively, they are manifested through changes in cognitive, emotional, perceptive and social experiencing. This review aims to summarize the current status of the limited number of studies with human subjects on the consequences of early childhood stress experiences with focus on the central nervous system.

Long-term consequences of aversive childhood experiences: effects on the incidence of psychiatric illnesses

Long-term consequences of aversive childhood experiences: effects on the incidence of psychiatric illnesses Abstract. Early childhood stress experiences through physical, psychological and sexual abuse as well as emotional or physical neglect often lead to permanent changes in the psychological well-being. Clinically, this is shown among other things in an increased incidence of various psychiatric disorders. This narrative survey aims to summarize the current status of existing studies on early childhood stress experiences and related psychiatric consequences. Scientific publications from the online libraries PubMed, PsycINFO and GoogleScholar served as the database. The search was conducted under the keywords Adversive Childhood Events (ACE), Adverse Childhood, Childhood Trauma, Psychiatric Disorders, Health Consequences as well as their German translations. The search resulted in 46 studies to be considered.

Cognitive readiness to parent, stability and change in postpartum parenting stress and social-emotional problems in early childhood: A second order growth curve model

Parenting stress (PS) is prospectively associated with children’s lowered socio-emotional functioning; however, little is known about the antecedents and consequences of changes in postpartum parenting stress and its relationship to problematic behaviors in early childhood. This research examined the longitudinal relationships between multiple measures of cognitive readiness to parent, parenting stress (initial level and growth) and child social-emotional competence at age 3. It was hypothesized that lack of cognitive readiness to parent would predict initial level and growth in PS and that initial level and change in parenting stress would, in turn, would be related to poor social-emotional development. Cognitive readiness to parent was assessed at baseline shortly after childbirth; parenting stress, conceptualized as difficult child, parent-child dysfunction and parental distress, was assessed at 6, 12, 24 and 36 months postpartum (i.e. when children were 6 months, 1, 2 and 3 years of age) using the Parenting Stress Index (PSI-SF; Abidin, 1995); children’s socio-emotional functioning was assessed with behavioral rating scale of the Bayley Scales of Infant Development (BSID-II) (BSID-II; Bayley, 1993) which was administered by professionals at age 3. Using a second order growth curve, or curve-of-factors model, the study’s hypotheses were tested with data from the Predicting and Preventing Neglect in Teen Mothers Study (2001–2007), a longitudinal study of 682 first-time mothers. Results from the latent growth curve analyses demonstrated that parenting stress predicted child socio-emotional problems. Specifically, mothers who began parenthood with high stress levels had children with lower levels of pro-social functioning (i.e. more behavior problems). Two measures of cognitive readiness to parent were associated with lower levels of postpartum PS at baseline but social support moderated the relationship between readiness to parent and parenting stress. Implications for interventions aimed at identifying families with children at risk for emotional and developmental problems and/or new parents who demonstrate changes in parenting stress during the postpartum period are discussed in context.

Exploring Trajectories of Young Mothers’ Parenting Stress in Early Childhood: Associations with Protective Factors and Psychological Vulnerabilities

SYNOPSIS Objective . Most parents manage some degree of parenting stress without serious concerns, but young mothers experience parenting stress at higher levels than adult mothers; high parenting stress is problematic due to its association with children’s socioemotional and behavior problems and the increased likelihood of maltreatment. Understanding the circumstances that precipitate or mitigate parents’ stress can have lasting impacts for child well-being. Extant research fails to account for both longitudinal and individual variation in young mothers’ parenting stress, leading to equivocal findings about the nature of mothers’ parenting stress trajectories across early childhood. Design . The present study used growth mixture modeling (GMM) to model the trajectories of 544 first-time young mothers’ parenting stress from children’s infancy to school-age. We considered how protective factors (i.e., social support) and psychological vulnerabilities (i.e., depression) experienced during the transition to parenthood were associated with parenting stress trajectories and variation within trajectories when children were of school-age. Results . GMM identified three trajectories of parenting stress: “low stable”, “high increasing”, and “high decreasing.” Protective factors were related to low and decreasing patterns of parenting stress, whereas psychological vulnerabilities were associated with higher parenting stress patterns. Conclusions . This study has implications for programs and services that help young mothers cope with the demands of parenting and reduce parenting stress.

American Indian young adults display diminished cardiovascular and cortisol responses to acute psychological stress

American Indian adults are at an increased risk for cardiovascular disease compared with non-Hispanic white adults. Scant research exists examining the underlying physiological and psychological mechanisms associated with these risks. This study aimed to examine possible psychological and physiological stress-related mechanisms related to cardiovascular disease risk in healthy American Indian and non-Hispanic white adults. Forty American Indian (60% female, Mean age = 19.93, SD = 2.08 years) and 45 non-Hispanic white (70% female, Mean age = 20.18, SD = 2.22 years) participants attended an in-person laboratory session. Salivary cortisol and cardiovascular activity were measured before (baseline), during, and after exposure to a 10-minute mental arithmetic task. Compared to non-Hispanic white participants, American Indian had diminished salivary cortisol (p < .001), blood pressure (p’s < .001), and heart rate (p = .041) responses to acute psychological stress. These effects could not be accounted for by differences in task performance or self-reported engagement. Previous research has shown that exaggerated responses to stress are associated with increased risk of cardiovascular disease. However, diminished responses to stress are associated with early childhood stress and future adverse behaviors (e.g., addiction, obesity). Diminished reactivity may influence behaviors that can impact future development of cardiovascular disease in American Indian populations.
