The impact of racial discrimination on the health of Australian Indigenous children aged 5-10 years: analysis of national longitudinal data

Breastfeeding rates of Aboriginal and Torres Strait Islander women in Australia: A systematic review and narrative analysis

BACKGROUND

Australian Aboriginal and Torres Strait Islander (referred to hereafter as Aboriginal) women breastfeed at lower rates than non-Aboriginal women, and rates vary across and within Aboriginal populations.

AIM

To determine rates of breastfeeding initiation and maintenance and compare individually collected survey data with existing routinely collected state and national breastfeeding data for Aboriginal women.

METHODS

CINAHL, Medline, EMBASE, SCOPUS, PsycINFO, and the Cochrane library were searched for peer-reviewed literature published between 1995 and 2021. Quantitative studies written in English and reporting breastfeeding for Aboriginal women or women having an Aboriginal infant were included. Screening and quality assessment included co-screening 10 % of papers. Two reviewers completed data extraction. A proportional meta-analysis was undertaken for breastfeeding initiation and narrative data synthesis used to summarise breastfeeding maintenance.

FINDINGS

The initial search identified 12,091 records, with 31 full text studies retrieved, and 27 reports from 22 studies met inclusion criteria. Breastfeeding initiation was 79 % (95 % CI 0.73, 0.85), however, rates were lower than non-Aboriginal women. Maintenance ranged between one week and five years. Rates and definitions varied significantly between studies, with inconsistencies in government collection and reporting of breastfeeding.

CONCLUSION

Significant variation in definitions and reporting make comparisons difficult. Breastfeeding rates were below recommended targets. Future pattern and trend analyses require standardised measures and definitions. Current collection and reporting of breastfeeding data, particularly routinely collected state-based data, is inadequate to present an accurate picture of current breastfeeding in Australia for Aboriginal women and infants, and to effectively inform interventions and policies.

The impact of the pandemic on mothers and children, with a focus on syndemic effects on black families: the "Prenatal to Preschool" study protocol

Introduction

Racism, a known social determinant of health, affects the mental health and well-being of pregnant and postpartum women and their children. Convincing evidence highlights the urgent need to better identify the mechanisms and the ways in which young children's development and mental health are adversely impacted by their mothers' experiences of racism. With the additional stressor of the COVID-19 pandemic, the criticality of improving knowledge of these domains has never been starker. The proposed project will address these questions and move the field forward to create targeted, culturally informed preventative interventions, thus achieving mental health equity for all children and families.

Methods

This prospective research is a cohort study that will longitudinally observe the outcomes of a cohort of mothers and their children recruited during the initial phase of the COVID-19 pandemic. Data will be parent/caregiver questionnaires assessing mental health, racism, support, and resilience at multiple time points with the first beginning at 24 months, clinical interviews with mothers, electronic medical records of mothers, and videotaped dyadic interactions at child age 24 and 48 months. A subset of Black participants will be asked to participate in qualitative interviews at child age 36 months.

Results

Analyze will be performed within and across Black and Non-Latino/a/e/x white (NLW) groups, and comparing mothers and fathers/secondary caregivers. Descriptive and multivariate analyzes will be run to better characterize how young children's development and mental health may be adversely impacted by their caregiver's experiences of racism.

Discussion

This prospective longitudinal mixed-methods study evaluates the simultaneous effects of the COVID-19 pandemic and racism on mothers and their developing children to characterize cross-racial differences, providing insight into risk and resilience factors in early development and the peripartum period.

Overweight/obesity and other predictors of gestational diabetes among Aboriginal and non-Aboriginal women in Western Australia

This population-based study investigated the association of BMI and other predictors with gestational diabetes mellitus (GDM) among Australian Aboriginal and non-Aboriginal mothers. We conducted a state-wide retrospective cohort study that included all singleton births in Western Australia (n = 134,552) between 2012 and 2015 using population health datasets linked by the Western Australian Data Linkage Branch. Associations between GDM and its predictors were estimated as adjusted relative risks (aRRs) from multivariable generalised linear models. Adjusted ratio of relative risks (aRRRs) compared RRs in Aboriginal and non-Aboriginal mothers. Adjusted population attributable fractions estimated the contribution of overweight/obesity to GDM burden, and adjusted predicted probabilities for GDM were plotted against BMI levels. The following predictors had stronger associations with GDM in Aboriginal, compared to non-Aboriginal, mothers: maternal obesity (aRR [95% CI] 3.16 [2.54-3.93]; aRRR 1.57 [1.26-1.94]), previous LGA (aRR 1.70 [1.37-2.12]; aRRR 1.41 [1.13-1.76]) and previous macrosomia (birthweight ≥ 4 kg) (aRR 1.55 [1.24-1.94]; aRRR 1.53 [1.22-1.91]). 46.1% (95% CI: 36.6-54.1) of GDM cases in Aboriginal women (23.3% in non-Aboriginal mothers, 95% CI: 21.6-25.1) were attributed to overweight/obesity. Compared to non-Aboriginal mothers, adjusted GDM probabilities were higher at all BMI levels and showed greater increase with BMI. Overweight/obesity is a key driver of GDM among Aboriginal women. Association between BMI and GDM is stronger in Aboriginal, compared to non-Aboriginal, women especially at higher BMI.

A longitudinal examination of psychosocial mechanisms linking discrimination with objective and subjective sleep

OBJECTIVE

Although chronic discrimination negatively impacts sleep, the cross-sectional nature of most research limits the understanding of how changes in discrimination over time are associated with sleep health. Therefore, the aims of this study were to explore the: (1) longitudinal association between daily discrimination and subjective and objective sleep; (2) mediating roles of anxiety and social well-being; and (3) moderating role of change in discrimination over time.

METHODS

An archival analysis was completed using data from the Midlife in the United States study across 3 timepoints. Participants were primarily female-identifying, white, and college-educated. Measures included Pittsburgh Sleep Quality Index (N = 958), sleep diaries (N = 307), and actigraphy (N = 304). Daily discrimination, the Social Well-Being Scale, and the Mood and Anxiety Symptom Questionnaire were also administered. Moderated parallel mediations were performed using the PROCESS macro controlling for depressive symptoms.

RESULTS

More discrimination at time 1 was associated with worse global sleep quality (b = 0.10 and p = .001) and daily sleep quality (b = 0.03 and p = .02) and worse objective sleep-onset latency (b = 0.93 and p = .02), wake after sleep onset (b = 1.09 and p = .002), and sleep efficiency (b = -0.52 and p < .001) at time 3. Social well-being mediated the associations between discrimination and subjective global sleep quality 95% CI [0.00, 0.03] and daily sleep quality 95% CI [0.00, 0.01] and objective TST 95% CI [0.00, 0.96] when discrimination was increasing or chronic. Anxiety mediated the discrimination-global sleep quality association regardless of changes in discrimination.

CONCLUSIONS

Discrimination showed durable associations with a broad array of sleep outcomes across a 10-year period. Anxiety and social well-being linked discrimination to subjective sleep outcomes, illustrating the importance of psychosocial well-being for sleep health in those experiencing discrimination.

Against the use of the Strengths and Difficulties Questionnaire for Aboriginal and Torres Strait Islander children aged 2-15 years

OBJECTIVE

The Strengths and Difficulties Questionnaire is a widely used screening tool for emotional and behavioural problems in children. Recent quantitative analyses have raised concerns regarding its structural validity in Aboriginal and Torres Strait Islander communities. This paper aims to extend upon existing findings by analysing the factor structure of both the parent- and teacher-reported Strengths and Difficulties Questionnaire in this population across a broader age range than in previous studies.

METHODS

Participants were the caregivers and teachers of 1624 Aboriginal and Torres Strait Islander children (820 male, 804 female) aged 2-15 years from Waves 2-11 of the Longitudinal Study of Indigenous Children. The majority of children were Aboriginal living in major cities and inner regional areas. Internal consistency was estimated with McDonald's Omega. Exploratory structural equation modelling was conducted to investigate the factor structure of the parent-reported and teacher-reported versions of the Strengths and Difficulties Questionnaire.

RESULTS

Responses from teachers demonstrated higher internal consistency than responses from parents, which was unacceptably low across most age groups. The purported five-factor structure of the Strengths and Difficulties Questionnaire failed to be replicated across both parent- and teacher-reported questionnaires. The results of bifactor and hierarchical exploratory structural equation models also failed to approximate the higher-order summary scales. These results indicate that the Strengths and Difficulties Questionnaire subscales and summary scores do not provide a valid index of emotional and behavioural problems in Aboriginal and Torres Strait Islander children.

CONCLUSION

The Strengths and Difficulties Questionnaire should not be used with Aboriginal and Torres Strait Islander children.

Perinatal outcomes of Aboriginal women with mental health disorders

OBJECTIVE

Maternal mental disorders have been associated with adverse perinatal outcomes such as low birthweight and preterm birth, although these links have been examined rarely among Australian Aboriginal populations. We aimed to evaluate the association between maternal mental disorders and adverse perinatal outcomes among Aboriginal births.

METHODS

We used whole population-based linked data to conduct a retrospective cohort study (N = 38,592) using all Western Australia singleton Aboriginal births (1990-2015). Maternal mental disorders were identified based on the International Classification of Diseases diagnoses and grouped into six broad diagnostic categories. The perinatal outcomes evaluated were preterm birth, small for gestational age, perinatal death, major congenital anomalies, foetal distress, low birthweight and 5-minute Apgar score. We employed log-binomial/-Poisson models to calculate risk ratios and 95% confidence intervals.

RESULTS

After adjustment for sociodemographic factors and pre-existing medical conditions, having a maternal mental disorder in the five years before the birth was associated with adverse perinatal outcomes, with risk ratios (95% confidence intervals) ranging from 1.26 [1.17, 1.36] for foetal distress to 2.00 [1.87, 2.15] for low birthweight. We found similar associations for each maternal mental illness category and neonatal outcomes, with slightly stronger associations when maternal mental illnesses were reported within 1 year rather than 5 years before birth and for substance use disorder.

CONCLUSIONS

This large population-based study demonstrated an increased risk of several adverse birth outcomes among Aboriginal women with mental disorders. Holistic perinatal care, treatment and support for women with mental disorders may reduce the burden of adverse birth outcomes.

Prenatal Maternal Stress and Pediatric Asthma Across Development: Adolescent Female-Specific Vulnerability

Prenatal maternal stress (PNMS) is linked to physical sequelae in offspring, including childhood asthma. This study sought to examine the roles of objective and subjective PNMS in the development of asthma at offspring ages 5 and 15. The sample included 815 mother-child dyads from the Mater Misericordiae Mothers' Hospital-University of Queensland Study of Pregnancy. PNMS was measured via retrospective self-report during pregnancy and 3-5 days after birth. Postnatal maternal stress was measured at offspring age 5. Objective PNMS was associated with elevated asthma risk at age 5 (OR 1.21, 95% CI 1.00, 1.45, p = 0.05), albeit not above concurrent postnatal stress. Sex moderated the association between PNMS and asthma at age 15, controlling for postnatal stress. Sex stratified analyses revealed a positive association between objective PNMS and age 15 asthma in females, but not males. Results provide evidence that PNMS may impact asthma outcomes in adolescence.

Patterns of Health and Health Service Use in a Prospective Cohort of Aboriginal and Torres Strait Islander Children Aged 5-9 Years Living in Urban, Regional and Remote Areas of South Australia

Despite longstanding recognition of disparities in Aboriginal and Torres Strait Islander child health, progress to reduce disparities is slow. To improve the capacity of policy makers to target resources, there is an urgent need for epidemiological studies providing prospective data on child health outcomes. We undertook a prospective population-based study of 344 Aboriginal and Torres Strait Islander children born in South Australia. Mothers and caregivers reported on child health conditions, use of health services and the social and familial context of the children. A total of 238 children with a mean age of 6.5 years participated in wave 2 follow-up. Overall, 62.7% of the children experienced one or more physical health conditions in the 12 months prior to wave 2 follow-up, 27.3% experienced a mental health condition and 24.8% experienced a developmental condition. The 12-month period prevalence of physical, developmental and mental health conditions was similar for children living in urban, regional and remote areas. While most children had had at least one visit with a general practitioner, some children experiencing physical, developmental and mental health conditions appear to be missing out on specialist and allied health care. Greater efforts by governments and policy makers are needed to strengthen outreach, recognition, referral and follow-up.

American Indian Alaska Native (AIAN) adolescents and obesity: the influence of social determinants of health, mental health, and substance use

OBJECTIVE

To explore the prevalence of obesity among American Indian and Alaska Native (AIAN) adolescents aged 12-19 years in association with social determinants of health (SDOH), and mental health and substance use disorders.

METHODS

Guided by the World Health Organization's Social Determinants of Health Framework, we examined data from the Indian Health Service (IHS) Improving Health Care Delivery Data Project from Fiscal Year 2013, supplemented by county-level data from the U.S. Census and USDA. Our sample included 26,226 AIAN adolescents ages 12-19 years. We described obesity prevalence in relationship to SDOH and adolescents' mental health and substance use disorder status. We then fit a multivariable logit generalized linear mixed model to estimate the relationships after adjusting for other individual and county level characteristics.

RESULTS

We observed a prevalence of 32.5% for obesity, 13.8% for mental health disorders, and 5.5% for substance use disorders. Females had lower odds of obesity than males (OR = 0.76, p < 0.001), which decreased with age. Having Medicaid coverage (OR = 1.09, p < 0.01), residing in a county with lower education attainment (OR = 1.17, p < 0.05), and residing in a county with higher rates of poverty (OR = 1.51, p < 0.001) were each associated with higher odds of obesity. Residing in a county with high access to a grocery store (OR = 0.73, p < 0.001) and residing in a county with a higher proportion of AIANs (OR = 0.83, p < 0.01) were each associated with lower odds of obesity. Those with mental health disorders had higher odds of obesity (OR = 1.26, p < 0.001); substance use disorders were associated with decreased odds of obesity (OR = 0.73, p < 0.001).

CONCLUSIONS

Our findings inform future obesity prevention and treatment programs among AIAN youth; in particular, the need to consider mental health, substance use, and SDOH.

Racism, xenophobia, and discrimination: mapping pathways to health outcomes

Despite being globally pervasive, racism, xenophobia, and discrimination are not universally recognised determinants of health. We challenge widespread beliefs related to the inevitability of increased mortality and morbidity associated with particular ethnicities and minoritised groups. In refuting that racial categories have a genetic basis and acknowledging that socioeconomic factors offer incomplete explanations in understanding these health disparities, we examine the pathways by which discrimination based on caste, ethnicity, Indigeneity, migratory status, race, religion, and skin colour affect health. Discrimination based on these categories, although having many unique historical and cultural contexts, operates in the same way, with overlapping pathways and health effects. We synthesise how such discrimination affects health systems, spatial determination, and communities, and how these processes manifest at the individual level, across the life course, and intergenerationally. We explore how individuals respond to and internalise these complex mechanisms psychologically, behaviourally, and physiologically. The evidence shows that racism, xenophobia, and discrimination affect a range of health outcomes across all ages around the world, and remain embedded within the universal challenges we face, from COVID-19 to the climate emergency.

Breastfeeding rates of Aboriginal and Torres Strait Islander women in Australia: a systematic review and narrative analysis

BACKGROUND

Australian Aboriginal and Torres Strait Islander (referred to hereafter as Aboriginal) women breastfeed at lower rates than non-Aboriginal women, and rates vary across and within Aboriginal populations.

AIM

To determine rates of breastfeeding initiation and maintenance and compare individually collected survey data with existing routinely collected state and national breastfeeding data for Aboriginal women.

METHODS

CINAHL, Medline, EMBASE, SCOPUS, PsycINFO, and the Cochrane library were searched for peer-reviewed literature published between 1995 and 2021. Quantitative studies written in English and reporting breastfeeding for Aboriginal women or women having an Aboriginal infant were included. Screening and quality assessment included co-screening 10% of papers. Two reviewers completed data extraction. A proportional meta-analysis was undertaken for breastfeeding initiation and narrative data synthesis used to summarise breastfeeding maintenance.

FINDINGS

The initial search identified 12,091 records, with 31 full text studies retrieved, and 27 reports from 22 studies met inclusion criteria. Breastfeeding initiation was 78% (95% CI 0.71, 0.84), however, rates were lower than non-Aboriginal women. Maintenance ranged between one week and five years. Rates and definitions varied significantly between studies, with inconsistencies in government collection and reporting of breastfeeding.

CONCLUSION

Significant variation in definitions and reporting make comparisons difficult. Breastfeeding rates were below recommended targets. Future pattern and trend analyses require standardised measures and definitions. Current collection and reporting of breastfeeding data, particularly routinely collected state-based data, is inadequate to present an accurate picture of current breastfeeding in Australia for Aboriginal women and infants, and to effectively inform interventions and policies.

Potential Determinants of Cardio-Metabolic Risk among Aboriginal and Torres Strait Islander Children and Adolescents: A Systematic Review

Prevention initiatives during childhood and adolescence have great potential to address the health inequities experienced by Aboriginal and Torres Strait Islander (Indigenous) populations in Australia by targeting modifiable risk factors for cardio-metabolic diseases. We aimed to synthesize existing evidence about potential determinants of cardio-metabolic risk markers—obesity, elevated blood pressure, elevated blood glucose, abnormal lipids, or a clustering of these factors known as the metabolic syndrome (MetS)—for Indigenous children and adolescents. We systematically searched six databases for journal articles and three websites for relevant grey literature. Included articles (n = 47) reported associations between exposures (or interventions) and one or more of the risk markers among Indigenous participants aged 0–24 years. Data from 18 distinct studies about 41 exposure–outcome associations were synthesized (by outcome: obesity [n = 18]; blood pressure [n = 9]; glucose, insulin or diabetes [n = 4]; lipids [n = 5]; and MetS [n = 5]). Obesity was associated with each of the other cardio-metabolic risk markers. Larger birth size and higher area-level socioeconomic status were associated with obesity; the latter is opposite to what is observed in the non-Indigenous population. There were major gaps in the evidence for other risk markers, as well as by age group, geography, and exposure type. Screening for risk markers among those with obesity and culturally appropriate obesity prevention initiatives could reduce the burden of cardio-metabolic disease.

Discrimination experienced by Aboriginal and Torres Strait Islander males in Australia: Associations with suicidal thoughts and depressive symptoms

INTRODUCTION

Globally, Indigenous populations have higher rates of suicidal behavior and psychological distress compared to non-Indigenous populations. Indigenous populations also report high rates of exposure to discrimination, which could potentially contribute to poor mental health outcomes. The objectives of this paper were to estimate the prevalence of discrimination among Aboriginal and Torres Strait Islander males in Australia and to examine the role of discrimination in the association between Aboriginal and Torres Strait Islander status and suicidal thoughts and depressive symptoms.

METHODS

We used cross-sectional data on 13,697 males aged 18-55 years from the Australian Longitudinal Study on Male Health. We undertook a Poisson regression with robust standard error analyses to examine Aboriginal and Torres Strait Islander status and self-perceived exposure to discrimination in the past 2 years as correlates of recent suicidal ideation. We used zero-inflated negative binomial regression to assess Aboriginal and Torres Strait Islander status and self-perceived exposure to discrimination as correlates of recent depressive symptoms.

RESULTS

Aboriginal and Torres Strait Islander males have a twofold higher prevalence of self-perceived discrimination (39.2% vs 19.3%, p < 0.001), suicidal ideation (21.8% vs 9.4%, p < 0.001) and moderate or worse depressive symptoms (24.0% vs 12.2%, p < 0.001) as compared to their non-Indigenous counterparts. After adjusting for sociodemographics and substance use, Aboriginal and Torres Strait Islander status was significantly associated with suicidal thoughts (odds ratio = 1.49, p = 0.019) and depressive symptoms (prevalence rate ratio = 1.19, p = 0.018). About 15.3% and 28.7% of the association between Aboriginal and Torres Strait Islander status and suicidal thoughts and depressive symptoms, respectively, was explained by discrimination.

CONCLUSION

Our analyses add to evidence that discrimination is a contributor to mental health disparities between Aboriginal and Torres Strait Islander and non-Indigenous populations in Australia. Reducing discrimination ought to be considered as part of strategies to improve the social and emotional well-being of Aboriginal and Torres Strait Islander people.

What are the effects of ethnicity, sexuality, disability and obesity on the odds of experiencing discrimination among Australian males? A nationwide cross-sectional survey

OBJECTIVES

The global public health community has been slow to acknowledge the important role of discrimination in health inequality. Existing evidence on discrimination is largely based on studies of specific subpopulations and specific forms of discrimination, with limited evidence from general population samples. We assessed the individual and combined effects of ethnicity, sexuality, disability and obesity on the likelihood of discrimination among a general population sample of Australian males.

DESIGN AND SETTING

We used data from The Australian Longitudinal Study on Male Health (n=15 988, with response rate of 35%) to estimate the prevalence of self-perceived discrimination within the preceding 2 years and we used binary logistic regression models to assess the individual and combined effects of ethnicity, sexuality, disability and obesity on discrimination.

PARTICIPANTS

13 763 adult males were included in this analysis.

RESULTS

One in five (19.7%) males reported experiencing discrimination in the preceding 2 years. Aboriginal and/or Torres Strait Islander males were nearly three times (OR=2.97, p<0.001) more likely to experience discrimination. Those born in Southern/Eastern Europe, Asia or Africa were at least twice more likely to report discrimination. Homosexual or bisexual males (35.2%; OR=2.23, p=<0.001), men with morbid obesity (29.2%; OR=1.91, p<0.001) and men with a disability (33.8%; OR=2.07, p<0.001) also had higher odds of experiencing discrimination. Those belonging to one (30.4%; OR=2.60, p<0.001) or two or more (38.2%; OR=3.50, p<0.001) risk groups were increasingly more likely to experience discrimination.

CONCLUSIONS

Discrimination was correlated with ethnicity, sexuality, obesity and disability. Belonging to two or more of the risk groups was associated with substantial increases in the likelihood of experiencing discrimination. Approaches to preventing discrimination need to acknowledge and address the impact of this intersectionality.

Family, neighborhood and psychosocial environmental factors and their associations with asthma in Australia: a systematic review and Meta-analysis

OBJECTIVE

Various associations between different environmental exposures and asthma have been reported in different countries and populations. We aimed to investigate the associations between family, neighborhood and psychosocial environmental factors and asthma-symptoms in Australia by conducting a systematic review and meta-analysis.

DATA SOURCES

We analyzed the primary research studies conducted in Australia across multiple databases, including PubMed, EMBASE and Scopus, published between 2000 and 2020.

STUDY SELECTIONS

The reviews and analyses focused on the overall association of different environmental exposures with the exacerbation of asthma-symptoms or asthma-related hospital visits. Quality-effect meta-analysis was done to estimate the pooled odds ratio for different environmental exposures for asthma-symptoms.

RESULTS

Among the 4799 unique published articles found, 46 were included here for systematic review and 28 for meta-analysis. Our review found that psychosocial factors, including low socioeconomic condition, maternal depression, mental stress, ethnicity, and discrimination, are associated with asthma-symptoms. Pooled analysis was conducted on family and neighborhood environmental factors and revealed that environmental tobacco smoking (ETS) (OR 1·69, 95% CI 1·19-2·38), synthetic bedding (OR 1·91, 95% CI 1·48-2·47) and gas heaters (OR 1·40, 95% CI 1·12-1·76) had significant overall associations with asthma-symptoms in Australia.

CONCLUSION

Although the studies were heterogeneous, both systematic review and meta-analysis found several psychosocial and family environmental exposures significantly associated with asthma-symptoms. Further study to identify their causal relationship and modification may reduce asthma-symptoms in the Australian population.

The needs and experiences of mothers while in prison and post-release: a rapid review and thematic synthesis

BACKGROUND

Women in prison are a vulnerable group, often with a history of abuse, out-of-home care, mental health problems and unemployment. Many are mothers when they become involved in the criminal justice system and their gender and parenting related needs are often not considered. The aim of this rapid review was to thematically synthesize the existing research on the needs and experiences of mothers while in, and following release from, prison in Australia.

METHODS

We conducted a rapid systematic search of electronic databases, search engines, the websites of key agencies, and contacted key agencies and researchers.

RESULTS

Twenty-two publications from 12 studies met the inclusion criteria and were thematically synthesized in relation to the mothers, their children, family and community, and systems and services which mothers had contact with. We found that mothers in prison have a history of disadvantage which is perpetuated by the trauma of imprisonment. Release from prison is a particularly challenging time for mothers. In relation to their children, the included studies showed that the imprisonment of mothers impacts their maternal identity and role and disrupts the mother-child relationship. Specific strategies are needed to maintain the mother-child relationship, and to ensure the needs and rights of the child are met. In relation to family and community, we found that although family and social support is an important need of women in prison, such support may not be available. Moreover, the stigma associated with having been in prison is a significant barrier to transitions into the community, including finding employment and housing. In relation to systems and services, although limited services exist to support women in prison and on release, these often do not consider the parenting role. Evaluations of parenting programs in prison found them to be acceptable and beneficial to participants but barriers to access limit the number of women who can participate.

CONCLUSION

Mothers have gender- and parenting-specific needs which should be considered in planning for corrective services in Australia. Any service redesign must place the woman and her children at the centre of the service.

Sex, ethnic and socioeconomic inequalities and trajectories in child and adolescent mental health in Australia and the UK: findings from national prospective longitudinal studies

BACKGROUND

This study investigates the sex, ethnic and socioeconomic inequalities in emotional difficulties over childhood and adolescence using longitudinal cohort studies in the UK and Australia. Estimating cross-national differences contributes to understanding of the consistency of inequalities in mental health across contexts.

METHODS

Data from 19,748 participants in two contemporary representative samples in Australia (Growing Up in Australia: The Longitudinal Study of Australian Children, n = 4,975) and UK (Millennium Cohort Study, n = 14,773) were used. Emotional difficulties were assessed using the parent-reported Strengths and Difficulties Questionnaire at ages 4/5, 6/7, 11/12 and 14/15 years and the self-reported Short Moods and Feelings Questionnaire at age 14/15. Latent Growth Curve Modelling was used to examine mental health over time.

RESULTS

There were significant increases in emotional difficulties in both countries over time. Emotional difficulties were higher in Australian children at all ages. The gender gap in self-reported depressive symptoms at age 14/15 was larger in the UK (8% of UK and 13% of Australian boys were above the depression cut-off, compared with 23% of girls). Ethnic minority children had higher emotional difficulties at age 4/5 years in both countries, but over time this difference was no longer observed in Australia. In the UK, this reversed whereby at ages 11/12 and 14/15 ethnic minority children had lower symptoms than their White majority peers. Socioeconomic differences were more marked based on parent education and employment status in Australia and by parent income in the UK. UK children, children from White majority ethnicity and girls evidenced steeper worsening of symptoms from age 4/5 to 14/15 years.

CONCLUSIONS

Even in two fairly similar countries (i.e. English-speaking, high-income, industrialised), the observed patterns of inequalities in mental health symptoms based on sociodemographics are not the same. Understanding country and context-specific drivers of different inequalities provides important insights to help reduce disparities in child and adolescent mental health.

Self-reported experiences of discrimination in older black adults are associated with insula functional connectivity

Self-reported experiences of discrimination are associated with a number of negative health outcomes. However, the neurobiological correlates of discrimination remain elusive. Recent neuroimaging work suggests that the amygdala is sensitive to forms of social adversity and the insula is involved in assessments of trust. We hypothesized that functional connectivity (FC) of these brain regions may be associated with discrimination in older Black adults. One-hundred and twenty-four nondemented older Black adults participating in the Minority Aging Research Study or the Clinical Core study of the Rush Alzheimer's Disease Center completed a measure of self-reported experiences of discrimination and a 3T MRI brain scan including structural T1 and resting-state fMRI EPIBOLD sequences. The right and left amygdala and insula regions were anatomically delineated as ROIs according to the Harvard-Oxford Brain Atlas and whole-brain voxelwise FC analyses were conducted using default parameters in the CONN toolbox. In regression analyses controlling for demographics and global cognition, self-reported experiences of discrimination were associated with greater FC between the left insula and the bilateral intracalcarine cortex, weaker FC between the left insula and the left dorsolateral prefrontal cortex, and weaker FC between the right insula and the left supplementary motor area. Amygdala analyses yielded no significant findings. Greater self-reported experiences of discrimination are associated with differential insula functional connectivity in older adults. More specifically, results suggest that discrimination is associated with differential connectivity of a key region (the insula) involved in trust perception.

Impact of racism and discrimination on physical and mental health among Aboriginal and Torres Strait islander peoples living in Australia: a systematic scoping review

Background

Racism is increasingly recognised as a significant health determinant that contributes to health inequalities. In Australia efforts have been made to bridge the recognised health gap between Aboriginal and Torres Strait Islander people and other Australians. This systematic scoping review aimed to assess, synthesise, and analyse the evidence in Australia about the impacts of racism on the mental and physical health of Aboriginal and Torrens Strait Islander peoples.

Methods

A systematic search was conducted to locate Australian studies in English published between 2000 and 2020. Five electronic databases were used: PubMed, CINAHL, Embase, Web of Science and the Australia’s National Institute for Aboriginal and Torres Strait Islander Health Research. The search strategy included a combination of key words related with racism, mental health, physical health and Indigenous people. Data were extracted based on review questions and findings were synthesized in a narrative summary.

Results

Of total 338 searched studies from five databases, 12 studies met the inclusion criteria for narrative synthesis where eight were cross-sectional studies and four prospective cohorts. General mental health and general health perception were the most frequently studied outcomes followed by child behaviour, smoking and substance consumption and specific health conditions. The prevalence of racism varied between 6.9 and 97%. The most common health outcomes associated with racism were general poor mental health and poor general health perception. More specific health outcomes such as anxiety, depression, child behaviour, asthma, increased BMI and smoking were also associated with racism but were analysed by a limited number of studies. Three studies analysed psychological distress, negative mental health, sleeping difficulties and negative perceived mental health according to severity of exposition to racism.

Conclusion

Racism is associated with negative overall mental and negative general health outcomes among Aboriginal and Torres Strait Islander peoples. Strategies to prevent all forms and sources of racism are necessary to move forward to bridging the health gap between Aboriginal and Torres Strait Islander peoples and non-Indigenous Australians. Further research is needed to understand in more detail the impact of racism from an Aboriginal and Torres Strait Islander definition of health and wellbeing.

Experiences of Racism among Older Aboriginal and Torres Strait Islander People: Prevalence, Sources, and Association with Mental Health

Cet article présente une analyse inédite de l'association entre la discrimination raciale et la détresse psychologique chez les personnes âgées indigènes et insulaires du détroit de Torres. Les résultats indiquent : (1) qu'une minorité importante d'aînés appartenant aux populations indigènes et insulaires du détroit de Torres ont été victimes de racisme (tel qu'expérimenté et mesuré en fonction d'inégalités de traitement) et d'évitement ; (2) qu'une association entre les expériences de racisme ou d'évitement et la détresse psychologique peut être mise en évidence, et que cette relation demeure robuste malgré la considération d'une variété de facteurs confondants et de caractéristiques complexes associées à la conception des enquêtes ; et (3) les associations entre le racisme et la détresse sont amplifiées en fonction de l'intensité du racisme et des comportements d'évitement. L'association reste robuste ou se trouve renforcée lorsque le racisme et l'évitement se produisent dans le cadre de contextes cruciaux au développement du capital humain des personnes âgées (p. ex. soins de santé, éducation, milieu de travail). Nos résultats soulignent l'importance des programmes et des services sociaux et de santé culturellement sécuritaires, ainsi que la nécessité de contrer la discrimination sous toutes ses formes.

This article presents the first nationally representative analysis of the association between racial discrimination and psychological distress among older Aboriginal and Torres Strait Islander people. Results show: (1) experiences of racism (as measured by unfair treatment) and avoidance are encountered by a significant minority of older Aboriginal and Torres Strait Islander people; (2) there is a clear association between experiences of racism and avoidance with psychological distress, with these results being robust to a range of confounding factors and complex survey design features; and (3) the associations between racism and distress are amplified by the severity of racism, and, when occurring, with avoidance. The association remains strong or is strengthened when racism and avoidance occur in contexts or situations crucial to the human capital development of older people (e.g., health care, education, and the workplace). Our findings underscore the importance of culturally safe health and social services/programs and further the imperative to address discrimination in all its forms.

Physical Activity Buffers the Adverse Impacts of Racial Discrimination on Allostatic Load Among Indigenous Adults

Background

Racial discrimination has been associated with biological dysfunction among ethnic minorities. The extent to which regular physical activity (PA) may buffer this association is unknown.

Purpose

To examine the association between past-year racial discrimination and allostatic load (AL) stratified by PA within a sample of Indigenous adults.

Methods

Data were collected from Indigenous adults attending university in a city in western Canada between 2015 and 2017. The Experiences of Discrimination Scale was used to assess discrimination and the Godin–Shephard Leisure-Time Physical Activity Questionnaire assessed PA. A composite of seven biomarkers assessing neuroendocrine, cardiovascular, metabolic, and immune system function measured AL. Linear regression models examined associations adjusted for confounders (N = 150).

Results

In the insufficiently active group, every 1 point increase in racial discrimination (up to a maximum of 9) resulted in approximately one third of a point increase in AL score. In the sufficiently active group, the association between racial discrimination and AL score was not statistically significant.

Conclusions

A growing body of research suggests racial discrimination is associated with multisystem biological dysregulation and health risks. Increased action to address racism in society is a priority. As that work unfolds, there is a need to identify effective tools that racialized groups can use to buffer the effects of racism on their health. The present findings suggest that engagement in regular PA may attenuate the pernicious effects of discrimination on biological dysfunction.

An Aboriginal and Torres Strait Islander Cardiac Rehabilitation program delivered in a non-Indigenous health service (Yeddung Gauar): a mixed methods feasibility study

BACKGROUND

There is limited evidence of Aboriginal and Torres Strait Islander people attending cardiac rehabilitation (CR) programs despite high levels of heart disease. One key enabler for CR attendance is a culturally safe program. This study evaluates improving access for Aboriginal and Torres Strait Islander women to attend a CR program in a non-Indigenous health service, alongside improving health workforce cultural safety.

METHODS

An 18-week mixed-methods feasibility study was conducted, with weekly flexible CR sessions delivered by a multidisciplinary team and an Aboriginal and/or Torres Strait Islander Health Worker (AHW) at a university health centre. Aboriginal and Torres Strait Islander women who were at risk of, or had experienced, a cardiac event were recruited. Data was collected from participants at baseline, and at every sixth-session attended, including measures of disease risk, quality-of-life, exercise capacity and anxiety and depression. Cultural awareness training was provided for health professionals before the program commenced. Assessment of health professionals' cultural awareness pre- and post-program was evaluated using a questionnaire (n = 18). Qualitative data from participants (n = 3), the AHW, health professionals (n = 4) and referrers (n = 4) was collected at the end of the program using yarning methodology and analysed thematically using Charmaz's constant comparative approach.

RESULTS

Eight referrals were received for the CR program and four Aboriginal women attended the program, aged from 24 to 68 years. Adherence to the weekly sessions ranged from 65 to 100%. At the program's conclusion, there was a significant change in health professionals' perception of social policies implemented to 'improve' Aboriginal people, and self-reported changes in health professionals' behaviours and skills. Themes were identified for recruitment, participants, health professionals and program delivery, with cultural safety enveloping all areas. Trust was a major theme for recruitment and adherence of participants. The AHW was a key enabler of cultural authenticity, and the flexibility of the program contributed greatly to participant perceptions of cultural safety. Barriers for attendance were not unique to this population.

CONCLUSION

The flexible CR program in a non-Indigenous service provided a culturally safe environment for Aboriginal women but referrals were low. Importantly, the combination of cultural awareness training and participation in the program delivery improved health professionals' confidence in working with Aboriginal people.

Social Patterning of Racial Discrimination Among a Diverse Sample of School-Aged Children in Australia

OBJECTIVE

To examine the prevalence of young childrens' reported experiences of racial discrimination and to assess whether discriminatory experiences vary by gender, religion and country of birth.

METHODS

Data came from Speak Out Against Racism (SOAR), a cross-sectional study of 4664 public school students in grades 5-9 in two Australian states in 2017. An adaption of the Adolescent Discrimination Distress Index (ADDI), as a measure of discrimination, was used across four Indigenous and ethnic categories (Indigenous, Asian and non-Asian visible minorities, Anglo/European). Effect-measure modification (EMM) examined how experiences of racial discrimination across ethnic groups varied by gender, country of birth and religion.

RESULTS

A sizeable proportion (40%) of students reported experiencing racial discrimination. Indigenous, Asian and non-Asian visible minority students reported higher rates of experiencing racial discrimination than their Anglo-European peers. Male students reported higher rates of experiencing racial discrimination than female students. Foreign-born students reported experiencing racial discrimination more often than native-born students, and both Christian and religious minorities experienced racial discrimination more often than students identifying with the dominant "No religion" group.

CONCLUSIONS

The findings highlight the prevalence of racial discrimination among adolescents and how gender, country of birth and religion can increase risk of these experiences.

Asthmatic Symptoms in Children and Adolescents: the Role of Maternal Experiences of Racial Discrimination

Emerging evidence suggests that vicarious racial experiences of discrimination may negatively influence child health. Few studies have focus on childhood asthma symptoms and potential moderators of such relationship.

METHODS

We used two population-based cross-sectional studies from the Social Change Allergy and Asthma in Latin America project in Salvador, Brazil. A total of 1003 children and mothers interviewed in 2006 were included, of whom 873 were reached again in 2013. Vicarious racial discrimination was assessed in mothers by applying the Experiences of Discrimination scale. Data on wheeze and environmental exposures were collected with standardized questionnaires. Levels of allergen-specific IgE were measured to identify atopy. Generalized estimating equations were used to estimate the association between maternal discrimination and wheezing and asthma phenotypes. Interaction terms were evaluated to identify whether mothers' mental health and family social support modified such associations.

RESULTS

Children whose mothers reported racial discrimination had greater odds of have asthma symptoms (OR 1.75; 95% CI 1.15-2.67) and non-atopic asthma (OR 1.92; 95% CI 1.09-3.40). When we considered effect modification by social support, we found a higher ORs when the level of social support was lower (OR 2.43; 95% IC 1.19-4.97) than when the level of social support was higher (OR 1.12; CI 0.64-1.96).

CONCLUSION

Maternal discrimination was associated with asthma symptoms and with non-atopic phenotype among their children. Enjoying wider social support network appears to buffer the effect on asthmatic symptoms. Intervention on childhood asthma needs to incorporate strategies that target the family.

Perceived Discrimination and Increased Odds of Unmet Medical Needs Among US Children

Our study examines the association between perceived discrimination due to race and unmet medical needs among a nationally representative sample of children in the United States. We used data from the 2016-2017 National Survey of Children's Health, a population-based cross-sectional survey of randomly selected parents or guardians in the United States. We compared results from the coarsened exact matching (CEM) method and survey-weighted logistic regression to assess the robustness of the results. Using self-reported measures from caregivers, we find that ∼2.7% of US children have experienced racial discrimination with prevalence varying significantly by race. While <1% of non-Hispanic whites have experienced some measure of racism, this increases to 8.8% among non-Hispanic blacks. Perceived discrimination was associated with significantly greater odds of unmet medical needs in the adjusted, survey-weighted multivariate-adjusted model (adjusted odds ratio [OR] = 2.4 and 95% confidence interval [CI] = 1.2, 4.9) as well as in the CEM-model estimate (OR = 2.8 and 95% CI = 1.8, 4.0). Children who have experienced perceived discrimination had higher odds of unmet medical needs. Awareness of discrimination among children may help inform future intervention development that addresses unmet medical needs during childhood.

Social Determinants of Health: the Impact of Racism on Early Childhood Mental Health

PURPOSE OF REVIEW

Despite increased literature on the impact of racism in the past decades, relatively few studies have focused on the effects of racism on younger children. This article reviews research from the past 5 years focusing on the impact of racism on infant and early childhood mental health and socioemotional development.

RECENT FINDINGS

Longitudinal studies provide evidence that very young children are highly influenced by exposure to multiple and interconnecting levels of racism and discrimination. These forms of exposure (structural and personally mediated, which can be further divided into direct and indirect exposure) are particularly nefarious to young children's socioemotional development and have implications for adolescent and adult mental health with lasting sequelae. Furthermore, the effects of racism on parenting practices and maternal/caregiver mental health appear to indicate mechanisms through which racism affects young children. Although more studies are needed in this area, recent literature indicates that racism is a social determinant of health that adversely impacts infant and early childhood socioemotional, and behavioral development. Future studies should focus on understanding the mechanisms through which racism impacts early childhood development and health, and interventions to prevent and mitigate the effects of racism.

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.

Racial Profiling, Surveillance and Over-Policing: The Over-Incarceration of Young First Nations Males in Australia

Historically, countries such as Australia, Canada and New Zealand have witnessed an increased over-representation of minority groups who are exposed to the criminal justice system. For many years in Australia, young First Nations males have been over-represented in the juvenile justice system in all states and territories. Many of these young males have disengaged from their schooling early, some through deliberate exclusion from the education system and others by choice. However, the choices for many young First Nations males may not be as clear cut as first might seem. This paper shows that over-representation in the juvenile justice system may be as a direct result of racial profiling, surveillance and over-policing of First Nations peoples within Australia. The literature addresses the ways in which young First Nations males experience these phenomena from an early age, and the long-term effects and consequences that can arise from these occurrences. An analysis of the current research both internationally and within Australia is thus conducted.

Sleep health in Indigenous Australian children: a systematic review

OBJECTIVE/BACKGROUND

The health and wellbeing of Indigenous Australian children has long been an issue of concern. However, to date there is a lack of attention to sleep health (particularly education and appropriate health service availability) in Indigenous Australians. The present review aimed to evaluate the prevalence of sleep problems in Indigenous Australians children.

METHOD

Up to August 2020, a systematic search using the keywords: "sleep problems"; "sleep disturbances"; "sleep quality"," "sleep disorder"; "sleep apnoea"; "obstructive sleep apnoea"; "OSA"; and "sleep-disordered breathing" AND "Indigenous Australians"; "Aboriginal"; "Torres Strait Islander"; was conducted on PubMed; Informit Indigenous Collection Scopus and CINAHL; "LIt.search tool" from the Lowitja Institute; Indigenous HealthInfoNet, Google Scholar (advanced), government agencies and relevant grey literature.

RESULTS

The search found only 13 studies focusing on sleep issues in Indigenous Australian children (birth to 17 years) with a pool of up to 4664 participants with 11 community-based studies (using mostly parental or self-report) and two in clinical populations (sleep laboratory). Three studies were longitudinal, all others were cross-sectional. Insomnia symptoms varied from 15% to 34.7%. Indigenous children reported severe daytime sleepiness (20%), short sleep (10.9%) late sleepers (50%). Snoring was reported in 14.2% with children in the community while up to 51% were objectively diagnosed to have OSA in a clinical setting.

CONCLUSION

The availability of only 13 studies investigating paediatric Indigenous sleep highlights the paucity of data in this area. Compared with non-indigenous people, Indigenous children are significantly more likely to experience short sleep duration and a high proportion reported symptoms of sleep disordered breathing. Working and conferring with Indigenous communities is an opportunity to engage in partnerships to improve sleep health and subsequently general health.

School-Based Prevention in Very Remote Settings: A Feasibility Trial of Methods and Measures for the Evaluation of a Social Emotional Learning Program for Indigenous Students in Remote Northern Australia

Purpose: Skills for Life (SFL) is a social-emotional curriculum for Indigenous middle school students that was co-developed with educators and community members in a remote community of northern Australia. This preliminary study aimed to test the feasibility of processes and methods of data-gathering, the reliability of youth self-report measures, and to identify the direction of effects for an evaluation of a longer-term pilot of the curriculum.

Design/Methodology/Approach: Indigenous Students in years 7–9 of a remote school participated in SFL over 2 years. The Strengths and Difficulties Questionnaire (SDQ), Kessler 6 (K6), and a purpose-designed Connected Self Scale (CSS) were administered to 63 students pre- and post-program.

Findings: Only the K6, Prosocial behavior (SDQ), and two CSS subscales showed sufficient internal consistency for analysis. Change was positive but non-significant for SDQ and CSS. There was evidence of a dosage effect: students receiving the intervention over 2 years showed greater reduction in psychological distress than other students. There was no evidence of iatrogenic effects.

Conclusions: The feasibility pilot is a critically important phase in the development of evaluation design and cjhoice of evaluation measures for challenging remote settings. This study found that evaluation of SFL with culturally and linguistically distinct Indigenous middle school students using self-report measures is feasible. However, the SDQ may not be suitable for this project. High levels of psychological distress suggest the need to investigate sources of life stress and potential supports for adolescent resilience in this context. This preliminary pilot aimed to trial methods and measures for evaluation of a social-emotional curriculum developed specifically for remote Australian Indigenous students who are at risk of poor psychosocial outcomes. No studies have examined the appropriateness of standardized self-report measures for evaluation of SEL with this student population in remote school settings.

Racial discrimination and allostatic load among First Nations Australians: a nationally representative cross-sectional study

BACKGROUND

Increased allostatic load is linked with racial discrimination exposure, providing a mechanism for the biological embedding of racism as a psychosocial stressor. We undertook an examination of how racial discrimination interacts with socioecological, environmental, and health conditions to affect multisystem dysregulation in a First Nations population.

METHODS

We conducted latent class analysis (LCA) using indicators of life stress, socioeconomic background, and physical and mental health from a nationally representative sample of Australian Aboriginal adults (N = 2056). We used LCA with distal outcomes to estimate the effect of the latent class variable on our derived allostatic load index and conducted a stratified analysis to test whether allostatic load varied based on exposure to racial discrimination across latent classes.

RESULTS

Our psychosocial, environmental, and health measures informed a four-class structure; 'Low risk', 'Challenged but healthy', 'Mental health risk' and 'Multiple challenges'. Mean allostatic load was highest in 'Multiple challenges' compared to all other classes, both in those exposed (4.5; 95% CI: 3.9, 5.0) and not exposed (3.9; 95% CI: 3.7, 4.2) to racial discrimination. Allostatic load was significantly higher for those with exposure to racial discrimination in the 'Multiple challenges' class (t = 1.74, p = .04) and significantly lower in the 'Mental health risk' class (t = - 1.67, p = .05).

CONCLUSIONS

Racial discrimination may not always modify physiological vulnerability to disease. Social and economic contexts must be considered when addressing the impact of racism, with a focus on individuals and sub-populations experiencing co-occurring life challenges.

Confronting Racism within the Canadian Healthcare System: Systemic Exclusion of First Nations from Quality and Consistent Care

The study is on racism against First Nation peoples in the Canadian healthcare system. The study design incorporates principles of grounded theory, participant and Indigenous (decolonizing) research. Four questions are addressed: (1) What is the root cause of racism against First Nation peoples in the healthcare system? (2) What factors perpetuate racisms existence? (3) What are the impacts of racism on First Nation health? (4) What needs to be done to eradicate racism and to create an equitable healthcare system that sufficiently represents the needs, interests and values of First Nation peoples?

Racial discrimination and socioemotional and sleep problems in a cross-sectional survey of Australian school students

OBJECTIVE

To determine the prevalence of direct and vicarious racial discrimination experiences from peer, school and societal sources, and examine associations between these experiences and socioemotional and sleep outcomes.

METHODS

Data were analysed from a population representative cross-sectional study of n=4664 school students in years 5-9 (10-15 years of age) in Australia. Students reported direct experiences of racial discrimination from peers, school and societal sources; vicarious discrimination was measured according to the frequency of witnessing other students experiences of racial discrimination. Students self-reported on the Strengths and Difficulties Questionnaire, with the total difficulties, conduct, emotional and prosocial behaviour subscales examined. Sleep problems included duration, latency, and disruption.

RESULTS

41.56% (95% CI 36.18 to 47.15) of students reported experiences of direct racial discrimination; Indigenous and ethnic minority students reported the highest levels. 70.15% (95% CI 63.83 to 75.78) of students reported vicarious racial discrimination. Direct and vicarious experiences of racial discrimination were associated with socioemotional adjustment (eg, for total difficulties, total direct racism: beta=3.77, 95% CI 3.11 to 4.44; vicarious racism: beta=2.51, 95% CI 2.00 to 3.03). Strong evidence was also found for an effect of direct and vicarious discrimination on sleep (eg, for sleep duration, total direct: beta=-21.04, 95% CI -37.67 to -4.40; vicarious: beta=-9.82, 95% CI -13.78 to -5.86).

CONCLUSIONS

Experiences of direct and vicarious racial discrimination are common for students from Indigenous and ethnic minority backgrounds, and are associated with socioemotional and sleep problems in adolescence. Racism and racial discrimination are critically important to tackle as social determinants of health for children and adolescents.

Sleep timing and sleep problems of preschoolers in Aotearoa/New Zealand: relationships with ethnicity and socioeconomic position

OBJECTIVES

To provide descriptive sleep data and explore sleep inequities, we investigated maternal reports of when and how well Māori (Indigenous) and non-Māori preschoolers sleep, and examined relationships between ethnicity (child and maternal), socioeconomic position (SEP) and sleep timing and problems of 3-4 year old children in Aotearoa/New Zealand (NZ).

METHODS

This study involved cross-sectional analysis of data from the Moe Kura: Mother and Child, Sleep and Wellbeing in Aotearoa/New Zealand longitudinal study. Log-binomial regression models were used to investigate associations between child and maternal demographic variables and preschooler bedtimes, social jetlag and maternally-reported sleep problems. Child models included child ethnicity, child gender, area- and individual-level deprivation. Maternal models included maternal ethnicity, maternal age, area- and individual-level deprivation.

RESULTS

340 Māori and 570 non-Māori preschoolers and their mothers participated. Māori preschoolers had later average bedtimes and wake times than non-Māori preschoolers. Ethnicity and area-level deprivation were independently associated with later bedtimes. Ethnicity was associated with social jetlag and sleep problems, independent of SEP. Individual-level deprivation was associated with problems falling asleep. Preschoolers of Māori mothers in least deprived areas were more likely to have problems falling asleep than preschoolers of non-Māori mothers in least deprived areas.

CONCLUSIONS

Research is needed to understand what sleep timing differences mean for preschoolers' wellbeing in NZ. Fundamental causes of social and economic disadvantage experienced by Indigenous children and mothers and by families who hold low SEP must be addressed, in order to eliminate sleep health inequities in early childhood.

Intersectionality, racial discrimination and oral health in Australia

BACKGROUND

There is a dearth of studies on the extent to which perceived racial discrimination shapes oral health. Following an intersectional perspective, we estimated the prevalence of perceived racial discrimination in Australia, its association with oral health impairment, and examined whether this association was more severe among low socioeconomic status (SES) groups.

METHODS

Data came from the 2013 National Dental Telephone Interview Survey (N = 2798), a population-based study of Australian adults. Multivariable Poisson regression models were estimated to test the relationship between perceived racial discrimination and self-reported oral health impairment, as well as to investigate whether the magnitude of this association was greater among low-SES respondents. Relative Excess Risks due to Interaction (RERI) were used to indicate the presence of potentially large discrimination effects within low-SES strata.

RESULTS

Racial discrimination in the past 12 months was reported by 11.5% of all participants. Australians reporting racial discrimination had 1.4 (95% CI 1.1, 1.7) times the prevalence of impaired oral health. The association between perceived racial discrimination and oral health impairment was stronger among low-SES groups. The RERI was 0.55, indicating a super-additive Effect Measure Modification (EMM) by income on the additive scale. Similar results were observed with the EMM analyses by educational attainment.

CONCLUSION

Our findings indicate that perceived racial discrimination, as a specific form of widespread inequality, is associated with higher frequencies of oral health impairment among Australian adults. We also suggest that socially marginalized groups bear a greater burden of the oral health effects of racial discrimination.

Discrimination Increases the Association Between Parental and Adolescent Allostatic Load in Chinese Rural-to-Urban Migrants

PURPOSE

This study was designed to examine the extent to which parents' allostatic load (AL) and adolescents' perceived discrimination are interrelated in the prediction of adolescents' AL among rural-to-urban migrants in China, as well as the possible buffering role of social support.

METHODS

Multi-informant data were collected in this study. A total of 158 rural-to-urban migrant adolescents (Mean_age = 11.62 years) and one of each of their parents (Mean_age = 39.84 years) were recruited from the suburbs of Beijing, China. Both adolescents' and parents' AL scores were based on 10 physiological indices. Migrant adolescents were asked to report their perceived discrimination and social support.

RESULTS

Parents' AL was significantly positively related to adolescents' AL. The relationship between parents' and adolescents' AL was stronger among adolescents reporting higher perceived discrimination than among those reporting lower. Social support moderated the adverse effects of parents' AL and perceived discrimination on adolescents' AL. Specifically, among adolescents reporting higher social support, the relationships between parents' and adolescents' AL were not significant for those with either high or low perceived discrimination. However, among adolescents reporting lower social support, the positive association was significant for those with high perceived discrimination but not for those with low perceived discrimination.

CONCLUSIONS

Parents' AL was a strong predictor of migrant adolescents' AL, and perceived discrimination acted as a catalyst to increase the association. The relationships of parental AL and perceived discrimination with AL were not significant for adolescents who received high social support.

Racial discrimination and child and adolescent health in longitudinal studies: A systematic review

RATIONALE

The association between racial discrimination and adverse health outcomes has been documented across an increasing body of evidence in recent years, although a close examination of longitudinal studies has not yet taken place. This review applied a life course lens in examining the evidence for a longitudinal association between racial discrimination exposure during childhood and adolescence, and later mental and physical health outcomes.

METHOD

Medline, PsycINFO, Global Health, ERIC, CINAHL Plus, Academic Search Premier and SocINDEX were searched from earliest records to October 2017 for eligible articles. Results were described through a narrative synthesis of the evidence.

RESULTS

Findings from 46 studies reported in 88 empirical articles published between 2003 and 2017 were identified. Studies were primarily based on cohorts from the United States, comprised of young people aged 11-18 years, and were published since 2010. Data were most frequently collected over two to three timepoints at intervals exceeding 12 months. Statistically significant associations with racial discrimination were most commonly reported for behaviour problems including delinquency and risk-taking behaviour, with significant adverse effects found in 74% of these associations. Statistically significant adverse effects were also reported in 63% of associations with health-harming behaviours including substance use, and 61% found associations with mental health outcomes. Consistently significant associations were reported between accumulated racism and later health outcomes, and the health effects of racism were reported to vary with developmental periods, although few studies featured these analyses.

CONCLUSIONS

Evidence from this review highlights that the duration and timing of exposure to racial discrimination matters. This review emphasises the need to gain evidence for the mechanisms linking early racism exposure to adverse health outcomes in later life. Future longitudinal research can address this need by capitalising on prospective cohort studies and ensuring that proposed analysis informs variable selection and timing of data collection.

Past-Year Racial Discrimination and Allostatic Load Among Indigenous Adults in Canada: The Role of Cultural Continuity

OBJECTIVE

This study aimed to examine the association between racial discrimination and allostatic load (AL) and whether this association was moderated by cultural continuity among Indigenous adults.

METHODS

Data were collected from Indigenous adults attending university in a small city in western Canada between 2015 and 2017 (mean age = 27.8 years). The Experience of Discrimination Situation Score and the Vancouver Index Enculturation Subscale were used to assess racial discrimination and cultural continuity, respectively. AL was measured as a composite of seven biomarkers assessing neuroendocrine, cardiovascular, metabolic, and immune system function. Bias-corrected and accelerated bootstrapped linear regression models were used to examine associations adjusting for confounders (n = 104; 72.5% women).

RESULTS

Across the full sample, racial discrimination was associated with a linear, dose-response increase in AL score after adjustment for confounders. Among adults with low cultural continuity, past-year discrimination was associated with increased AL and explained 22% (adjusted R) of the variance in AL score. Taken together, the full model including age, sex, and income explained 38% of the variance in AL score in this subgroup. Among adults with high cultural continuity, racial discrimination was not associated with AL, whereas age remained significant and explained 13% of the variance in AL score.

CONCLUSIONS

Past-year racial discrimination was associated with early and more pronounced wear and tear on stress response systems among Indigenous adults relative to peers. Indigenous cultural continuity served as an important buffer that promoted biological resilience against the adverse effects of racial discrimination on physiologic regulation among Indigenous adults.

Bedsharing and Breastfeeding: The Academy of Breastfeeding Medicine Protocol #6, Revision 2019

A central goal of the Academy of Breastfeeding Medicine is the development of clinical protocols for managing common medical problems that may impact breastfeeding success. These protocols serve only as guidelines for the care of breastfeeding mothers and infants and do not delineate an exclusive course of treatment or serve as standards of medical care. Variations in treatment may be appropriate according to the needs of an individual patient.

Racial discrimination and the health and wellbeing of Aboriginal and Torres Strait Islander children: Does the timing of first exposure matter?

Racial discrimination has been observed to negatively impact on the health of Aboriginal and Torres Strait Islander children, although evidence surrounding periods of greater vulnerability to the stressor of racism have not yet been explored in this population. We compared first exposure to interpersonal racism at either ages 4-5 years or 7 years with no exposure to examine the influence of sensitive periods of racism exposure on mental health and physiological outcomes during middle childhood (7-12 years). The study cohort comprised 1,759 Aboriginal and Torres Strait Islander children aged 4-12 years from waves 2-8 (2009-2015) of the Footprints in Time: 1The Longitudinal Study of Indigenous Children (LSIC) dataset. Multilevel logistic regression was used in all analysis. We observed a larger effect (OR: 2.8; 95% CI: 1.4-5.4) for negative mental health with first exposure at 4-5 years compared to 7 years (OR: 2.1; 95% CI: 1.2-3.6), referenced to children with no exposure. Effect sizes were similar in both exposure groups for the significantly increased risk of sleep difficulties, while a stronger adverse effect on behavioural issues was found at 7 years (OR: 2.2; 95% CI: 1.3-4.0) relative to 4-5 years (OR: 1.7; 95% CI: 0.8-3.7). No significant associations were found with general health, obesity or being underweight. This study generates new evidence surrounding sensitive periods of exposure to racism in Aboriginal and Torres Strait Islander children. A pattern of consistently greater adverse effects on mental and physiological health was not observed with first exposure at 4-5 compared to 7 years, although initial evidence indicates that first exposure to racism at these ages increases the likelihood of negative mental health relative to children without racism exposure. Longitudinal data extending from earlier to later developmental periods will allow further investigations into the presence of sensitive periods of exposure to racism in these children.

Caregiver-perceived racial discrimination is associated with diverse mental health outcomes in Aboriginal and Torres Strait Islander children aged 7-12 years

BACKGROUND

Racial discrimination is acknowledged as a central social determinant of Australian Aboriginal and Torres Strait Islander (hereafter referred to as Aboriginal) health, although quantitative empirical literature on the impacts of racism on Aboriginal children remains sparse. We use a novel, longitudinal dataset to explore the relationship between caregiver-perceived racism exposure and a range of mental health and related behavioural and physiological outcomes in childhood.

METHOD

The study cohort comprised 1759 Aboriginal children aged 4-12 years from waves 2-8 (2009-2015) of the Footprints in Time: The Longitudinal Study of Indigenous Children (LSIC) dataset. We examined exposure to caregiver-perceived racism between 4 and 11 years as a predictor for mental health and related outcomes at ages 7-12 and substance use at 10-12 years. Unadjusted models and models adjusted for remoteness, community-level and family-level socio-economic status, child age and gender were used in analysis. Multilevel logistic regression was used in all analysis.

RESULTS

In fully adjusted models, perceived exposure to racism at ages 4-11 was associated with twice the risk of negative mental health (95% CI: 1.3-3.0), sleep difficulties (95% CI: 1.4-3.0), and behaviour issues at school (95% CI: 1.2-2.9), 1.7 times the risk of obesity (95% CI: 1.1-2.5), and nearly 7 times the risk of trying cigarettes (95% CI: 1.1-43.9). Increased risks were also found for being underweight and trying alcohol though estimates did not reach statistical significance. There was no evidence that racism was associated with poorer general health.

CONCLUSION

Exposure to racial discrimination in Aboriginal children increased the risk for a spectrum of interrelated psychological, behavioural and physiological factors linked to negative mental health. Our results further affirm the importance of interventions aimed at reducing the prevalence of racial discrimination for the benefits of population health and health inequalities. The services and institutions which aim to support the mental health and wellbeing of Aboriginal children should also support interventions to reduce racism and implement accountable policies which prioritise this goal.

Effects of racism on the socio-emotional wellbeing of Aboriginal Australian children

BACKGROUND

Racism is a pervasive experience in the life of Aboriginal Australians that begins in childhood. As a psychosocial stressor, racism compromises wellbeing and impacts developmental trajectories. The purpose of the present study was to estimate the effect of racism on indicators of Australian Aboriginal child socio-emotional wellbeing (SEWB) at one to two years after exposure. Age-related differences in the onset of symptoms were explored.

METHODS

Data from the B- and K-cohorts of the Longitudinal Study of Indigenous Children were used (aged 6 to 12 years). Racism, confounding variables, and the Strengths and Difficulties Questionnaire (a measure of SEWB) were collected by questionnaires and guided interviews with each child's main caregiver. Adjusted Poisson regression was used to estimate the relative risk (RRa) effects of racism on SEWB for both cohorts separately. RRa were pooled in a random effects meta-analysis.

RESULTS

Exposure to racism was associated with an adjusted point estimate indicating a 41% increased risk for total emotional and behavioural difficulties, although the confidence intervals were wide (pooled RRa 1.41, 95% CI 0.75, 2.07). Analyses by cohort showed younger children had higher RRa for total difficulties (RRa 1.72, 95% CI 1.16, 2.54), whilst older children had higher RRa for hyperactive behaviour (RRa 1.66, 95% CI 1.01, 2.73).

CONCLUSIONS

The effects observed contributes to our understanding of the impact of racism on Aboriginal Australian children. Support for emotional and behavioural difficulties, and hyperactive behaviour, for Aboriginal children might help counteract the effects of racism. Future longitudinal research and policies aimed at reducing racism in Australian society are necessary.

Trends in mental health related contacts among mothers of Aboriginal children in Western Australia (1990-2013): a linked data population-based cohort study of over 40 000 children

OBJECTIVE

This study examines the scale of maternal mental health related contacts among Australian Aboriginal children over time, and associations with socio-economic characteristics, geographical remoteness and maternal age.

DESIGN

A retrospective cohort study of the prevalence of maternal mental health related contacts among Aboriginal children born in Western Australia between 1990 and 2013.

SETTING

Population of Western Australia with de-identified linked administrative data from the Western Australian Department of Health.

PARTICIPANTS

All Aboriginal children born in Western Australia between 1990 and 2013 and their mothers.

PRIMARY OUTCOME MEASURE

Prevalence of maternal mental health related contacts among Aboriginal children born between 1990 and 2013. Mental health related contacts were identified using mental health related inpatient hospitalisations and outpatient contacts.

RESULTS

Almost 30% of cohort children were born to a mother with at least one mental health contact in the 5 years prior to birth, with 15% reported in the year prior to birth and the year post birth. There was a distinct increase in the prevalence of maternal mental health contacts between 1990 and 2013 (4-5% per year, with a peak in 2007). Maternal mental health contacts were associated with living in more disadvantaged areas and major cities, and having a mother aged over 20 years at birth.

CONCLUSIONS

The study affirms that mental health issues place a considerable burden on Aboriginal Australia, and suggests that many of the mental health issues that women develop earlier in life are chronic at the time of conception, during pregnancy and at birth. Early intervention and support for women in the earliest stages of family planning are required to alleviate the burden of mental health problems at birth and after birth. There is a clear need for policies on the development of a holistic healthcare model, with a multisector approach, offering culturally appropriate services for Aboriginal people.
