Somatic complaints in children and community violence exposure

Academic Achievement After Violence Exposure: The Indirect Effects of School Attachment and Motivation to Succeed

Disparities in educational outcomes for students living in communities burdened with high rates of violence are striking as they are at an increased risk for misbehavior, low GPA, poor school attendance, and decreased standardized test scores. However, limited research identifies the role that schools play in exacerbating exposure to violence to inform changes that aid in mitigating violence exposure. As such, this study utilizes the Pathways to Desistance Study to explore the mediating roles of school attachment and motivation to succeed on students' academic outcomes after exposure to community violence. Using a serial mediation model, findings indicate that school attachment and motivation to succeed mediate the relationship between exposure to violence and grades. Implications for adapting school programs and policies as well as providing teacher training to increase school attachment and motivation are discussed.

The neighborhood environment and sleep health in adolescents

OBJECTIVE

Neighborhood-level factors, including education, health and environment, and socioeconomic exposures, are important contextual determinants of child health. We explored whether these factors, measured via the Childhood Opportunity Index 2.0, were associated with sleep health in adolescents.

METHODS

Actigraphy was used to assess sleep duration, timing, and efficiency among 110 adolescents in eighth (13.9 (0.4)) and ninth (14.9 (0.4)) grade. Home addresses were geocoded and linked to Childhood Opportunity Index 2.0 scores (including 3 subtype scores and the 29 individual factor Z-scores). Mixed-effects linear regression was used to determine associations between the Childhood Opportunity Index 2.0 scores and the sleep outcomes, adjusting for sex, race, parent education, household income, school grade and weeknight status. Interactions were also tested by school grade, weeknight status, sex, and race.

RESULTS

No associations were observed between overall or subtype scores with sleep outcomes in adolescents. However, we detected associations between select individual Childhood Opportunity Index 2.0 Z-scores, spanning health & environment and education domains, and sleep outcomes. For example, greater fine particulate matter was associated with later timing of sleep onset and offset; ozone concentration was associated with earlier sleep onset and offset; greater exposure to extreme temperature was associated with later sleep onset and offset and increased odds of optimal sleep efficiency.

CONCLUSIONS

Specific neighborhood factors indexed by the Childhood Opportunity Index 2.0 were associated with sleep health among adolescents. In particular, neighborhood air quality measures were associated with sleep timing and efficiency, warranting further investigation.

The Impact of Adverse Childhood Experiences and Community Violence Exposure on a Sample of Anxious, Treatment-Seeking Children

Screening for adverse childhood experiences (ACEs) can help prevent and reduce adverse outcomes on child development, including increased risk for anxiety disorders. Emerging studies strongly support the inclusion of community-level adversities in ACE screeners to consider diverse contexts and populations. Recent studies suggest that community violence exposure (CVE) may have a distinct impact on youth mental health. Although recent studies have examined the association between ACEs, CVE, and mental health in primary care settings, this association has not been examined on treatment-seeking children in urban mental health settings. The present study employs a mediation model using the PROCESS macro to examine community violence exposure mediating the effect on the association between ACEs and somatic symptoms (SS) on a sample of anxious treatment-seeking children. A total of 98 participants (Mage = 11.7, SD = 3.79, 51.6% males, 54.1% ethnic minority children) who sought services at a specialized anxiety clinic completed self-report measures. Results indicated that exposure to ACEs is associated with endorsement of somatic symptoms as a result of reporting hearing, witnessing, or experiencing CVE. Evidence of mediation was found in a statistically significant indirect effect of ACEs on SS through CREV (Effect = .17, 95% CI = .069-.294). These findings support recent evidence that CVE is a distinct ACE as it contributes to toxic stress similar to individual-level ACEs. The use of a comprehensive ACE screening that includes CVE is warranted, particularly when working with culturally and socioeconomically diverse populations, as it would better capture a broader range of adversities across demographic groups.

Examining the interactive association of family- and neighborhood-level socio-economic characteristics on children's sleep beyond the associations of residency and neighborhood violence

OBJECTIVE

To examine the interactive association of neighborhood and family socio-economic characteristics (SEC) on children's sleep.

DESIGN

Secondary data analyses were completed on the 2014 Ontario Child Health Study, a cross-sectional sample of 10,802 children aged 4-17.

PARTICIPANTS

Children (aged 4-11, 50% male; N = 6264) with available sleep outcome data.

METHODS

Multilevel modeling was used to assess the interactive relationship between family- and neighborhood-level poverty in relation to child sleep outcomes (problems falling asleep, problems staying asleep, weekday and weekend time in bed), above the associations of variables known to be related to sleep at the child (ie, child age, sex, internalizing problems, externalizing problems, chronic illness), family (ie, negative parenting behaviors, family structure, parent mental health, years lived in neighborhood, parent education level), and neighborhood levels (ie, neighborhood size, antisocial behavior).

RESULTS

Neighborhood poverty (p < .01, ß = -0.001, 95% confidence interval [-0.007, -0.002]) was significantly related to shorter weekday time in bed and the interactive association of family and neighborhood poverty was significantly related to weekend time in bed (p < .05, ß = 0.012, 95% confidence interval [0.004, 0.021]). Children living in low poverty neighborhoods with families of higher SEC backgrounds, and children living in high poverty neighborhoods with families of lower SEC backgrounds had the shortest weekend time in bed (9.7 hours).

CONCLUSIONS

There is a compound relationship of family and neighborhood poverty on children's sleep above and beyond family- and child-level risk factors.

Effect of Welding Separation Characteristics on the Cyclic Behavior of Steel Plate Shear Walls

Currently, the steel plate shear wall (SPSW) is commonly used in high-rise steel buildings as a lateral load-resisting system due to its several advantages such as its lightweight and high ductility and strength. The SPSW consists of two main parts, i.e., the boundary frame and infill plate, which are connected by welding. The objective of this work is to study the effect of the infill plate weld separation on the seismic behavior of the SPSWs. A numerical method was proposed to have a comprehensive comparison of seismic behaviors of different separation characteristics. The model was validated by using previously published experimental works. Key parameters, such as load-carrying capacity, stiffness, and energy-dissipation capacity, were discussed extensively. The unstiffened SPSW (USPSW) system is more sensitive to the plate–beam separation than the plate–column one, especially the corner plate–beam separation. When plate–column welding separation occurs, the initial stiffness and the energy dissipation capacity are reduced by approximately 21% and 14%, respectively; however, the reductions are 36% and 20.5% in the case of beam welding separation.

Sleep Duration Buffers The Effects of Adversity on Mental Health Among Recently Immigrated Latinx Adolescents

The rate of Latinx migration to the U.S. has risen rapidly over the last several decades. Recognizing that Latinx migrant youth are exposed to a high rate of adverse events and that sleep has potential buffering effects on mental health, the current study aimed to examine sleep duration as a moderator of the link between childhood adversity and emotional and behavioral symptoms among Latinx migrant youth. One hundred and twelve first-generation migrants of Latinx ethnicity (and 46 caregivers) participated in this study; the average age was 19 (SD = 2). Participants self-reported demographics: 59.8% of participants were male, with the racial breakdown as follows: 38.8% white, 6.1% black, 4.1% mixed race, and 51% marked "other." Data were collected from a public high school for immigrant youth in the Southwestern U.S. and included average sleep duration, Adverse Childhood Experiences; the Child PTSD Symptoms Scale and the Child Behavior Checklist. Findings indicated experiences of neglect in childhood were associated with youth-reported mental health symptoms, but this relation was significantly moderated by sleep duration such that the relation was weakened in the presence of high sleep duration. Both effects were statistically significant and of medium size. Caregiver reports supported the buffering effects of sleep; medium or large interactions between sleep and all three adversity variables (abuse, neglect, and household dysfunction) were noted in multivariate analyses. The current study takes an important first step in identifying that short sleep duration is prevalent among Central American immigrant youth. Findings suggest that sleep duration has important public health potential as a means of buffering the effects of childhood adversity on mental health in a vulnerable group.

Families With Violence Exposure and the Intergenerational Transmission of Somatization

INTRODUCTION

Adults who have histories of childhood trauma have been noted to display greater somatization, dissociative symptoms and affect dysregulation. What happens in the parent-child relationship when those traumatized children become parents? A potential link to somatization in the child has been suggested by several prior studies. Children who have early attachment disturbances had more physical complaints if their mothers displayed less maternal sensitivity during observed parent-child interactions. Yet, the intergenerational link between maternal and child somatization has not been sufficiently explored in a longitudinal study in order to understand the potential impact of maternal trauma history and related psychopathology on subsequent child somatization and psychopathology.

METHODS

This paper examined prospective, longitudinal data of 64 mother-toddler dyads (mean age = 2.4 years, SD = 0.7) who were later studied when children had a mean age of 7 years. Mothers with and without histories of interpersonal violence (IPV; physical/sexual abuse and/or family violence exposure) were included. Mothers with IPV histories were oversampled. Linear and Poisson regression models were used to test the associations between maternal IPV-related post-traumatic stress disorder (PTSD) with maternal somatization severity when children were toddlers, and between maternal somatization and maternal interactive behaviors with child somatization by maternal report and clinician-rated assessment at school-age.

RESULTS

Maternal PTSD severity was significantly associated with increased maternal somatization severity (p = 0.031). Maternal somatization severity during the child's early childhood predicted both maternal report of child somatization (p = 0.011) as well as child thought problems (p = 0.007) when children were school-aged. No association was found between maternal somatization and child-reported psychopathology. The study did not find that maternal alexithymia, caregiving behaviors or child exposure to violence contributed significantly to the model examining the association between maternal and child somatization.

CONCLUSION

The results are in line with the hypothesis of intergenerational transmission of somatization in the context of IPV and related maternal PTSD during formative early development. We interpret this as an expression of psychological distress from mother to child, as maternal trauma and pathology affect the caregiving environment and, thus, the parent-child relationship. The authors conclude with a discussion of implications for parent-infant and early childhood intervention.

Neighborhood environments and sleep among children and adolescents: A systematic review

Understanding salient environmental determinants of pediatric sleep is essential for informing interventions and public health initiatives. Emerging evidence suggests that the neighborhood environment can impact pediatric sleep, but this evidence has not yet been systematically reviewed. We conducted a systematic review of the scientific literature on associations between neighborhood environments and sleep in young children (0-5 y), school-aged children (6-12 y) and adolescents (13-18 y). We reviewed 85 articles published between 2003 and 2020. The most commonly examined neighborhood exposure was low socioeconomic status (40 studies), which was associated with sleep outcomes in 58% of studies (primarily shorter sleep duration, later sleep timing, or obstructive sleep apnea). Evidence was stronger for neighborhood safety/crime/violence (21 studies), with 86% of studies reporting associations with sleep outcomes (primarily self- or caregiver-reported sleep problems). Fewer studies examined associations of neighborhood physical environment exposures, including noise (15 studies), the built environment (seven studies), and air pollution (six studies). Limitations of the current body of evidence include 1) limited examination of neighborhood exposures other than socioeconomic status or safety, 2) use of primarily cross-sectional observational study designs, 3) lack of objective sleep outcome assessment, and 4) limits of current exposure assessment methods.

Social and early life adversity and chronic health conditions among Tunisian adults

Early life adversities (ELAs) are shown as significant risk factors for chronic health conditions (CHCs). ELAs include multiple types of abuse such as the social abuse (peer, community, and collective violence). The purpose is to describe the relationship between childhood social abuse and chronic conditions in adulthood among a sample of adults in Tunisia and to investigate the role of obesity and tobacco use as mediators of this association. A cross-sectional study was conducted in Tunisia, from January to June 2016 using the Arabic Adverse Childhood Experiences International Questionnaire (ACE-IQ). Items of social abuse (peer violence, witnessing community violence, and exposure to collective violence) were analyzed. A total of 2,120 adults were enrolled. After adjustment for age, gender, and intrafamilial ELA, social adversities were associated significantly with the selected CHC. Experiencing more than two social ELA increase the risk of occurrence of hypertension and coronary diseases. After accounting for the indirect effect of body mass index, statistically significant partial mediation effects were observed for the cumulative number of social ELA as the exposure variable and chronic diseases as the outcome variable (p ≤ .001; % mediated = 44.5%). These findings support an association between many chronic health disorders and childhood social abuse, independently of intrafamilial ACEs.

Exposure to violence affects the development of moral impressions and trust behavior in incarcerated males

Individuals exposed to community violence are more likely to engage in antisocial behavior, resulting in a dramatic increase in contact with justice and social service systems. Theoretical accounts suggest that disruptions in learning underlie the link between exposure to violence and maladaptive behaviors. However, empirical evidence specifying these processes is sparse. Here, in a sample of incarcerated males, we investigated how exposure to violence affects the ability to learn about the harmfulness of others and use this information to adaptively modulate trust behavior. Exposure to violence does not impact the ability to accurately develop beliefs about agents' harm preferences and predict their choices. However, exposure to violence disrupts the ability to form moral impressions that dissociate between agents with distinguishable harm preferences, and subsequently, the ability to adjust trust behavior towards different agents. These findings reveal a process that may explain the association between exposure to violence and maladaptive behavior.

Nausea in the peri-traumatic period is associated with prospective risk for PTSD symptom development

While nausea often develops following exposure to trauma, little is known regarding the relationship between peri-traumatic nausea and prospective risk for developing posttraumatic stress disorder (PTSD). We examined the association between peri-traumatic nausea and PTSD symptom development in three independent cohorts. Participants were recruited from (1) the Emergency Departments (ED) at Grady Memorial Hospital (GMH) in Atlanta, GA, (2) from multiple other ED sites in the TRYUMPH Research Network, and (3) from the ED during evaluation for suspected acute coronary syndrome in the REACH cohort. Administration of IV ondansetron, the most predominant antiemetic used at GMH, was used as a surrogate marker for nausea in the initial GMH cohort; nausea was then directly assessed in the internal validation at GMH, and within the replication TRYUMPH Research Network and REACH cohorts. In the GMH cohort (N = 363), ondansetron administration was associated with increased 1- and 3-month posttrauma PTSD symptoms in adjusted models (all p's < 0.05). In the GMH internal validation, nausea significantly predicted 1 month (p = 0.009; n = 68) and 3 month (p = 0.029; n = 54) PTSD symptoms. In the TRYUMPH cohort (N = 1846), patient reported nausea in the ED was significantly associated with increased PTSD symptoms (p = 0.009) in adjusted models. In the REACH cohort (N = 758), peri-traumatic nausea was associated with PTSD symptom severity at the 1-month follow-up in adjusted models (p's ≤ 0.008). The current prospective data from three independent cohorts suggest that peri-traumatic nausea is a prospective predictor of PTSD symptom development. Further studies are needed to determine the mechanistic role of nausea as an intermediate phenotype of PTSD risk.

Systematic Review: Exposure to Community Violence and Physical Health Outcomes in Youth

Objective

To systematically review the evidence for associations between exposure to community violence and physical health outcomes in children and adolescents.

Methods

A thorough search of multiple online databases and careful consideration of inclusion and exclusion criteria yielded a final 28 studies for detailed review. In addition to review of findings, studies were rated on overall quality based on study design.

Results

Seven categories of physical health outcomes emerged, including asthma/respiratory health, cardiovascular health, immune functioning, hypothalamic-pituitary-adrenal axis functioning, sleep problems, weight, and a general health category. There were mixed findings across these categories. Evidence for a positive association between community violence exposure and health problems was strongest in the cardiovascular health and sleep categories.

Conclusion

There is reason to believe that community violence exposure has an effect on some areas of physical health. Additional well-designed research that focuses on mechanisms as well as outcomes is warranted.

Childhood Exposure to Violence and Chronic Physical Conditions in a National Sample of US Adolescents

OBJECTIVES

Exposure to violence is associated with chronic physical conditions in adults. Although violence exposure is common among youths, it is unknown whether violence is associated with chronic physical conditions in childhood and adolescence. We examined the associations of violence exposure with chronic physical conditions in a population-representative sample of US adolescents and determined whether associations were explained by co-occurring mental disorders.

METHODS

Data were drawn from the National Comorbidity Survey Replication-Adolescent Supplement (NCS-A), a national cross-sectional survey of 6,483 adolescents (ages 13-17). Lifetime exposure to violence; Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition mood, anxiety, and substance disorders; and self-reported arthritis, frequent headaches, back or neck problems, other chronic pain, asthma, and allergies were assessed.

RESULTS

One in 4 (24.99%) adolescents reported exposure to violence. Violence exposure was associated with elevated odds of back/neck pain, headaches, chronic pain, allergies, and asthma (odds ratio [OR], 1.5-2.1; 95% confidence interval [CI], 1.1-3.5) after adjustment for sociodemographics, socioeconomic status, and lifetime mental disorders. Regarding new onsets, violence exposure was associated with greater hazard for subsequent first-onset only of back/neck pain (hazard ratio, 1.9; 95% CI, 1.2-3.0) and headaches (hazard ratio, 1.4; 95% CI, 1.1-1.8), and these associations were explained by early-onset mental disorders.

CONCLUSIONS

Childhood violence exposure is associated with chronic physical conditions that emerge early in the life course, although associations are stronger for prevalent than incident conditions. Violence exposure predicts incident pain conditions only, and these associations are explained by mental disorders that begin after violence exposure. Interventions and policies aimed at preventing violence and detecting and treating early-onset mental disorders have the potential to reduce morbidity, mortality, and health disparities beginning early in development.

Somatic symptoms among US adolescent females: associations with sexual and physical violence exposure

The objective of this study is to examine the association between physical and sexual violence exposure and somatic symptoms among female adolescents. We studied a nationally representative sample of 8,531 females, aged 11-21 years, who participated in the 1994-1995 Wave I of the National Longitudinal Study of Adolescent Health (Add Health). Female adolescents were asked how often they had experienced 16 specific somatic symptoms during the past 12 months. Two summary categorical measures were constructed based on tertiles of the distributions for the entire female sample: (a) total number of different types of symptoms experienced, and (b) number of frequent (once a week or more often) different symptoms experienced. Groups were mutually exclusive. We examined associations between adolescents' violence exposure and somatic symptoms using multinomial logistic regression analyses. About 5 % of adolescent females reported both sexual and non-sexual violence, 3 % reported sexual violence only, 36 % reported non-sexual violence only, and 57 % reported no violence. Adolescents who experienced both sexual and non-sexual violence were the most likely to report many different symptoms and to experience very frequent or chronic symptoms. Likelihood of high symptomatology was next highest among adolescents who experienced sexual violence only, followed by females who experienced non-sexual violence only. Findings support an exposure-response association between violence exposure and somatic symptoms, suggesting that symptoms can be markers of victimization. Treating symptoms alone, without addressing the potential violence experienced, may not adequately improve adolescents' somatic complaints and well-being.

Emotional and Behavioral Problems among Impoverished Kenyan Youth: Factor Structure and Sex-Differences

Data on youth emotional and behavioral problems from societies in Sub-Saharan Africa are lacking. This may be due to the fact that few youth mental health assessments have been tested for construct validity of syndrome structure across multicultural societies that include developing countries, and almost none have been tested in Sub-Saharan Africa. The Youth Self-Report (YSR), for example, has shown great consistency of its syndrome structure across many cultures, yet data from only one developing country in Sub-Saharan Africa have been included. In this study, we test the factor structure of YSR syndromes among Kenyan youth ages 11-18 years from an informal settlement in Nairobi, Kenya and examine sex-differences in levels of emotional and behavioral problems. We find the eight syndrome structure of the YSR to fit these data well (Root Mean Square Error of Approximation=.049). While Kenyan girls have significantly higher internalizing (Anxious/Depressed, Withdrawn/Depressed, Somatic) problem scores than boys, these differences are of similar magnitude to published multicultural findings. The results support the generalizability of the YSR syndrome structure to Kenyan youth and are in line with multicultural findings supporting the YSR as an assessment of emotional and behavioral problems in diverse societies.

Somatic symptoms, peer and school stress, and family and community violence exposure among urban elementary school children

Somatic symptoms are a common physical response to stress and illness in childhood. This study assessed 409, primarily African American (85.6 %), urban elementary school children to examine the association between: (1) somatic symptoms and potential external stressors (school and peer stress, family conflict, and community violence) and (2) parent and child agreement on children's self-report of somatic symptoms. The odds of self-report of somatic complaints were significantly associated with family conflict, school and peer stress, and community violence exposure (OR = 1.26, 95 % CI: 1.05-1.50; OR = 1.18, 95 % CI 1.08-1.28; and OR = 1.02, 95 % CI: 1.00-1.05, respectively). Identifying the associations between social, family, and community based stress and somatic symptoms may improve the quality of life for children living in urban environments through early identification and treatment.

Complex traumatic stress in the pediatric medical setting

There has been a recent increase in research focusing on child complex traumatic stress following prolonged or repeated trauma. These traumatic stress reactions often affect many aspects of the child's functioning, including psychological, behavioral, and physical health. In addition, complex traumatic stress experienced by youth with serious medical conditions may influence health issues such as medical adherence, emotional adjustment to illness, and pain management. This article reviews and delineates the current state of the literature on the impact of complex traumatic stress in childhood on mental and physical health as well as on these pediatric health-related issues. To date, few empirical studies have directly addressed this association. Several features associated with complex traumatic stress, such as emotion regulation difficulties, disruptive behavior, and family conflict, have indirectly been demonstrated to interfere with pediatric adherence, medical coping, and pain management. This demonstrates the need for more focused research in this area.

Somatic symptoms in traumatized children and adolescents

Childhood exposure to trauma has been associated with increased rates of somatic symptoms (SS), which may contribute to diminished daily functioning. One hundred and sixty-one children residing at a residential treatment home who had experienced neglect and/or abuse were administered the Trauma Symptom Checklist for Children (TSCC), the Multidimensional Anxiety Scale for Children, and the Children's Depression Inventory (CDI). Primary caregivers completed the Child Behavior Checklist. Two composite measures of SS were formed to represent both child- and caregiver-rated SS. Over 95% of children endorsed at least one SS on the child-rated measure. Children who had experienced sexual abuse had higher rates of SS relative to children who had not. Child-rated SS were highly correlated with the CDI total score and the TSCC subscales of anxiety, depression, posttraumatic stress, dissociation, and anger. The TSCC anxiety subscale mediated the relationship between sexual abuse and child-rated SS.

Noncardiac chest pain in children and adolescents: a biopsychosocial conceptualization

Pediatric NCCP may be characterized by recurrent pain accompanied by emotional distress and functional impairment. This paper reviews and critiques literature on pediatric noncardiac chest pain (NCCP) and introduces a theoretical conceptualization to guide future study of NCCP in children and adolescents. A developmentally informed biopsychosocial conceptualization of NCCP etiology is proposed based on a synthesis of empirical evidence and clinical observations of pediatric NCCP within the context of relevant findings from the broader pediatric pain and anxiety literature. Multiple factors from biological, psychological, social, familial, and developmental domains are potentially relevant to the etiology of this ailment. This article concludes with directions for future research and clinical implications.

Relationship proximity to victims of witnessed community violence: associations with adolescent internalizing and externalizing behaviors

Witnessing community violence has been linked with several adverse outcomes for adolescents, including emotional and behavioral problems. Among youth who have witnessed community violence, proximity to the victim of community violence is one factor that may determine, in part, the nature of adolescents' responses to community violence exposure. The present study examines whether relationship proximity to the victim of community violence is associated with internalizing and externalizing behaviors among a sample of urban and predominantly African American adolescents (N = 501) who have witnessed community violence. In 10th grade, participants reported whether they had witnessed 10 community violence events during the past year, and, if so, whether the victim of the violence was a family member, close friend, acquaintance, or stranger. Witnessed community violence against a family member or close friend was associated with depressive symptoms, and witnessed community violence against known individuals was associated with anxiety symptoms. Witnessing community violence against familiar persons and strangers was linked with aggressive behavior. Gender differences in these associations and implications for assessment and intervention with community violence-exposed youth are discussed.

Does controlling for comorbidity matter? DSM-oriented scales and violent offending in Chicago youth

Mental health problems have long been linked to antisocial behaviors. Despite an impressive body of literature demonstrating this relationship and claims that comorbidity matters, few studies examine comorbidity using multiple distinct mental health indicators, with most studies instead adopting single or composite mental health measures. This study tested separate and comorbid effects of five DSM-oriented mental health issues on self-reported violence using a community-based sample of Chicago youths from the Project on Human Development in Chicago Neighborhoods. Moreover, it utilized both primary caregiver and youth self-reports of psychopathology across four developmental stages of childhood and adolescence. When examined separately, the results indicated affective/depressive, anxiety, attention deficit hyperactivity, and oppositional defiant/antisocial personality problems independently predicted violence. When considering comorbidity, however, only oppositional defiant and antisocial personality problems significantly predicted violence at any stage, regardless of informant type. Implications for future studies and policy are discussed.

Frequent visitors: somatization in school-age children and implications for school nurses

There is a gap in the nursing literature regarding children who frequently visit school nurses' offices with recurrent unexplained physical symptoms. A review of the scientific health literature was undertaken to examine the clinical presentation, associated variables, and implications for school nurses regarding children who are frequent school health office visitors with somatic symptoms. This subset of students with medically unexplained symptoms accounts for disproportionate use of primary care and school health resources. Common somatic complaints in school-age children, such as headache and stomachache, are associated with the psychosocial variables of anxiety and depression, childhood adversity, and school stress. Effective and practical treatment approaches to this complicated child health issue require accurate identification, appropriate referral, screening for associated conditions, and individualized treatment plans. Research to identify effective interventions for frequent health office visitors is needed.

Neighborhood psychosocial hazards and the association of cumulative lead dose with cognitive function in older adults

Before the 1970s, today's older Americans were exposed to high levels of lead in the environment. The authors previously reported that lifetime cumulative lead dose was associated with lower cognitive test performance in older adults. Experiments suggest that environmental stress may intensify the detrimental influence of lead. No large, population-based studies of this question have been done. The authors evaluated whether cross-sectional associations of tibia lead with cognitive function were modified by neighborhood psychosocial hazards in the Baltimore Memory Study (2001-2005), a longitudinal cohort study of determinants of cognitive decline. Tibia lead was measured via (109)Cd-induced K-shell X-ray fluorescence. Neighborhood psychosocial hazards were measured independently of study subjects. Complete data were available among 1,001 demographically diverse adults aged 50-70 years, randomly selected from 65 contiguous neighborhoods in Baltimore City. Hierarchical mixed-effects regression models showed that neighborhood psychosocial hazards exacerbated the adverse associations of tibia lead in 3 of 7 cognitive domains after adjustment for age, sex, race/ethnicity, education, testing technician, and time of day (language, P = 0.039; processing speed, P = 0.067; executive functioning, P = 0.025). The joint occurrence of environmental stress and lead exposure across the life span may partially explain persistent racial/ethnic and socioeconomic disparities in cognitive function in late life.

Racial, ethnic, and sex differences in the associations between violence and self-reported health among US high school students

BACKGROUND

Involvement in interpersonal violence or suicidal behaviors can have a significant impact on an adolescent's physical health. Similarly, previous research has suggested that lived experiences, more than the presence or absence of physical ailments, can significantly influence self-assessed health status among adolescents. The purpose of this study was to examine the cross-sectional associations between involvement in violence and poor or fair self-reported health among US high school students.

METHODS

Data were obtained from the 2005 national Youth Risk Behavior Survey (n = 13,953). Logistic regression analyses were conducted to determine the associations between violence-related measures and self-reported health while controlling for demographic characteristics and potential confounders. Analyses are presented for students overall and stratified by sex and race/ethnicity.

RESULTS

Overall, 7.2% of students reported fair or poor self-rated health. Having been in a physical fight, having been injured in a physical fight, having attempted suicide, and having not gone to school because of safety concerns were significantly associated with fair or poor self-rated health after controlling for demographic characteristics and other potential confounders. Differences associated with race/ethnicity and sex are identified.

CONCLUSIONS

Four of the 5 violence-related measures included in these analyses were significantly associated with fair or poor self-rated health. Future studies should consider the impact of involvement in violent behaviors and perceptions of both physical and mental well-being.

Influence of multiple social risks on children's health

OBJECTIVE

Social risk factors such as growing up in poverty, racial/ethnic minority status, and maternal depression have been associated with poorer health outcomes for children. This study examined the strength of association of 8 social risk factors, both individually and as part of a cumulative social risk index, on parent-reported child health status.

METHODS

We performed an analysis of cross-sectional data from the 2003 National Survey of Children's Health, a telephone survey of 102,353 parents of children aged 0 to 17 years. In bivariate and multivariate logistic regression models, 8 social risk factors were tested as independent predictors of 4 parent-reported child health outcomes: global health status, dental health, socioemotional health, and overweight. These risk factors were combined into a categorical "social risk index" ranging from low risk (0 risk factors) to very high risk (> or = 6 risk factors), and risk gradients were examined using linear polynomial testing and multivariate logistic regression.

RESULTS

The percentage of children in poorer health increased with the number of social risk factors across all health outcomes. More than half of children had > or = 2 risk factors, and 24% had > or = 4. Low maternal mental health, black or Hispanic race/ethnicity, < 200% of the federal poverty level, low household education, unsafe neighborhoods, and lack of health insurance increased the odds for less than very good child health in adjusted models.

CONCLUSIONS

Multiple social risk factors have a cumulative effect on parent-reported child health status across physical and socioemotional domains, demonstrating a very strong risk gradient effect. These findings emphasize the importance of addressing multiple levels of social risk to achieve improvements in child health.
