Are maternal and community risk factors associated with the presence of asthma among children placed in foster care?

Community violence and asthma: A review

Over the past 2 decades, epidemiologic studies have identified significant associations between exposure to violence, as a psychosocial stressor, and the incidence or exacerbation of asthma. Across diverse populations, study designs, and measures of community violence, researchers have consistently identified adverse associations. In this review, the published epidemiologic evidence is summarized with special attention to research published in the last 5 years and seminal papers. Hypothesized mechanisms for the direct effects of violence exposure and for how such exposure affects susceptibility to physical agents (eg, air pollution and extreme temperature) are discussed. These include stress-related pathways, behavioral mechanisms, and epigenetic mechanisms. Finally, clinical implications and recommendations are discussed.

Racial and Ethnic Disparities in the Physical Health Outcomes of Children in Foster Care: A Systematic Review

Children of color-especially Black and Indigenous children-are disproportionately overrepresented in foster care and experience barriers in accessing services and receiving physical and behavioral healthcare compared to their White counterparts. Although racial disparities in mental health outcomes of children in foster care have been examined systematically, less is known about racial disparities in their physical health outcomes. This systematic review aimed to examine disparities in physical health outcomes (i.e., general health, developmental delays and disability, chronic illness, health-compromising behaviors, all-cause mortality) of children in foster care by their race and ethnicity (PROSPERO ID: CRD42021272072). Systematic literature searches were conducted in PubMed, EMBASE, PsycINFO, CINAHL, Cochrane Library, and Psychology and Behavioral Sciences Collection. Of the 6,102 unique studies identified, 24 met inclusion criteria: peer-reviewed journal article; published from 1991 to 2021; written in English; involved children in the U.S. foster care system; children were primarily in family-based placements; included health outcomes; included children's race and ethnicity; conducted quantitative analyses; and had an observational study design. There was limited evidence to suggest racial disparities among physical health domains examined, in part, due to the small number of studies, variability across study measures and designs, how race and ethnicity were categorized, and how related results were reported. Research that disaggregates results by more nuanced race and ethnicity categories, goes beyond including race and ethnicity as control variables, and uses more robust study designs to understand where racial disparities lie is necessary to inform practice and policy efforts to attain race and health equity in child welfare.

Child Welfare System Involvement Among Children With Medical Complexity

Children with medical complexity may be at elevated risk of experiencing child maltreatment and child welfare system involvement, though empirical data are limited. This study examined the extent of child welfare system involvement among children with medical complexity and investigated associated health and social factors. A retrospective chart review of children with medical complexity (N = 208) followed at a pediatric hospital-based complex care program in Canada was conducted. Descriptive statistics and odds ratios using logistic regression were computed. Results showed that nearly one-quarter (23.6%) had documented contact with the child welfare system, most commonly for neglect; of those, more than one-third (38.8%) were placed in care. Caregiver reported history of mental health problems (aOR = 3.19, 95%CI = 1.55-6.56), chronic medical conditions (aOR = 2.86, 95%CI = 1.09-7.47), and interpersonal violence or trauma (aOR = 17.58, 95%CI = 5.43-56.98) were associated with increased likelihood of child welfare system involvement, while caregiver married/common-law relationship status (aOR = 0.35, 95%CI = 0.16-0.74) and higher number of medical technology supports (aOR = 0.75, 95%CI = 0.57-0.99) were associated with decreased likelihood. Implications for intervention and prevention of maltreatment in children with high healthcare needs are discussed.

The Relationship Between Neighborhood Safety and Children's Asthma: An Integrative Review

INTRODUCTION

There is a growing body of research analyzing the relationships between neighborhood safety and children's asthma prevalence and control. There are several inconsistencies in concepts and methods that have led to mixed results. The purpose of this review is to critically evaluate the current evidence analyzing neighborhood safety and childhood asthma and identify nursing research and policy implications.

METHOD

An integrative review was conducted by searching the PubMed, CINAHL, EMBASE, and PsychINFO databases to identify peer-reviewed articles published between 2010-2017. Fourteen studies met inclusion criteria.

RESULTS

Overall, there was evidence pointing to associations among neighborhoods being unsafe and higher asthma prevalence and/or poorer asthma control.

DISCUSSION

The association between neighborhood safety and children's asthma warrants further research with universal definitions for neighborhood safety and multi-level modelling. The review also supports the "Health in All Policies" approach as safety is one of several social determinants of health that influence children's asthma.

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.

Maternal sensitivity and social support protect against childhood atopic dermatitis

BACKGROUND

Many studies have identified associations between qualities of maternal-child relationships and childhood asthma, but few have examined associations with childhood atopic dermatitis (AD), a common precursor to asthma. Moreover, maternal psychological distress, including prenatal and postnatal depression, anxiety and stress, may increase risk, while social support from partners may reduce risk for childhood AD. We sought to uncover the association between maternal-infant relationship qualities (maternal sensitivity towards infant behavioral signals, controlling behavior, and unresponsiveness) and child AD after accounting for risk (i.e., prenatal and postnatal maternal depression, anxiety and stress) and protective (i.e., social support) factors.

METHODS

We conducted a secondary analysis of data collected on a subsample of 242 women and their infants enrolled during pregnancy in the ongoing Alberta Pregnancy Outcomes and Nutrition cohort study. Inclusion criteria required mothers to be >16 years of age, English speaking and <22 weeks gestational age at enrollment. Data on depression, anxiety and stress in the prenatal and postnatal periods and physician diagnosis of childhood AD at 18 months were gathered via maternal report. Maternal sensitivity, unresponsiveness and controlling behaviours were assessed via videotaped observations using the Child-Adult Relationship Experimental (CARE)-Index at 6 months of infant age.

RESULTS

Higher maternal sensitivity, or the inability of the mother to appropriately understand and respond to infant needs based on behavioral signals, predicted reduced odds of AD independent of and in combination with low prenatal and postnatal anxiety and high paternal support. After adjustment, higher maternal controlling behaviours and unresponsiveness also predicted greater odds of AD.

CONCLUSIONS

Low maternal sensitivity is a risk factor for childhood AD, independently and in combination with perinatal anxiety and low social support. Thus, interventions that improve maternal-infant relationship quality, especially sensitivity, reduce anxiety and improve social support from partners could reduce odds of childhood AD.
