Understanding pathways to inequalities in child mental health: a counterfactual mediation analysis in two national birth cohorts in the UK and Denmark.

ABSTRACT: OBJECTIVES:We assessed social inequalities in child mental health problems (MHPs) and how they are mediated by perinatal factors, childhood illness and maternal mental health in two national birth cohorts. DESIGN:Longitudinal cohort study SETTING: We used data from the UK Millennium Cohort Study and the Danish National Birth Cohort. PRIMARY AND SECONDARY OUTCOME MEASURES:We applied causal mediation analysis to longitudinal cohort data. Socioeconomic conditions (SECs) at birth were measured by maternal education. Our outcome was child MHPs measured by the Strength and Difficulty Questionnaire at age 11. We estimated natural direct, indirect and total effects (TEs) of SECs on MHPs. We calculated the proportion mediated (PM) via three blocks of mediators-perinatal factors (smoking/alcohol use during pregnancy, birth weight and gestational age), childhood illness and maternal mental health. RESULTS:At age 11 years, 9% of children in the UK and 3.8% in Denmark had MHPs. Compared with high SECs, children in low SECs had a higher risk of MHPs (relative risk (RR)=4.3, 95% CI 3.3 to 5.5 in the UK, n=13 112; and RR=6.2, 95% CI 4.9 to 7.8 in Denmark, n=35 764). In the UK, perinatal factors mediated 10.2% (95% CI 4.5 to 15.9) of the TE, and adding maternal mental health tripled the PM to 32.2% (95% CI 25.4 to 39.1). In Denmark, perinatal factors mediated 16.5% (95% CI 11.9 to 21.1) of the TE, and including maternal mental health increased the PM to 16.9% (95% CI 11.2 to 22.6). Adding childhood illness made little difference in either country. CONCLUSION:Social inequalities in child mental health are partially explained by perinatal factors in the UK and Denmark. Maternal mental health partially explained inequalities in the UK but not in Denmark.

Project description:BackgroundEvidence regarding the presence and persistence of ethnic inequalities in mental healthcare is well established. The reasons for these inequalities and lack of progress in diminishing them are less understood. This meta-ethnography aims to provide a new conceptual understanding of how ethnic inequalities are created and sustained; this is essential to develop effective interventions. Specifically, we sought to understand why people from ethnic minority groups are underrepresented in primary care mental health service provision and overrepresented in crisis pathways and detention.Methods and findingsFollowing eMERGe guidelines for meta-ethnographies, we searched OpenGrey, Kings Fund, CINAHL, Medline, PsycINFO, and Social Care Online databases for qualitative articles published from database inception until October 2, 2022, using broad categories of search terms relating to "ethnicity AND (mental illness/mental health/emotional distress) AND (help-seeking/service utilisation/experience/perception/view)." We included all conceptually rich articles that used qualitative methods of data collection and analysis and excluded non-UK studies and those that focused solely on causation of mental illness. Our patient, public, and practitioner lived experience advisory group provided feedback and input on key stages of the project including search terms, research questions, data analysis, and dissemination. A total of 14,142 articles were identified; 66 met the inclusion criteria. We used reciprocal, refutational, and line of argument analytical approaches to identify convergence and divergence between studies. The synthesis showed that current models of statutory mental healthcare are experienced as a major barrier to the delivery of person-centred care to those in ethnic minority groups due to the perceived dominance of monocultural and reductionist frameworks of assessment and treatment (described as "medical" and "Eurocentric") and direct experiences of racist practice. The lack of socially oriented and holistic frameworks of knowledge and understanding in medical training and services is experienced as epistemic injustice, particularly among those who attribute their mental illness to experiences of migration, systemic racism, and complex trauma. Fear of harm, concerns about treatment suitability, and negative experiences with health providers such as racist care and medical neglect/injury contribute to avoidance of, and disengagement from, mainstream healthcare. The lack of progress in tackling ethnic inequalities is attributed to failures in coproduction and insufficient adoption of existing recommendations within services. Study limitations include insufficient recording of participant characteristics relating to generational status and social class in primary studies, which prevented exploration of these intersections.ConclusionsIn this study, we found that the delivery of safe and equitable person-centred care requires a model of mental health that is responsive to the lived experiences of people in ethnic minority groups. For the people considered in this review, this requires better alignment of mental health services with social and anti-racist models of care. Our findings suggest that intersections related to experiences of racism, migration, religion, and complex trauma might be more relevant than crude ethnic group classifications. Strategies to tackle ethnic inequalities in mental healthcare require an evaluation of individual, systemic, and structural obstacles to authentic and meaningful coproduction and implementation of existing community recommendations in services.

Project description:BackgroundPopulation groups experience differential access to timely and high-quality mental healthcare. Despite efforts of recent UK policies to improve the accessibility of mental health services, there remains a lack of comprehensive understanding of inequalities in access to services needed to do this. This systematic mapping review aimed to address this gap by identifying which population groups continue to be poorly served by access to adult mental health services in the UK, how access has been measured, and what research methods have been applied.MethodsSeven electronic databases were searched from January 2014 up to May 2022. Primary research studies of any design were included if they examined access to adult NHS mental health services in the UK by population groups at risk of experiencing inequalities. Study characteristics, measures of access, inequalities studied, and key findings were extracted. A best-fit framework approach was used, applying Levesque's Conceptual Framework for Healthcare Access to synthesise measures of access, and applying a template derived from Cochrane Progress-Plus and NHS Long Term Plan equality characteristics to synthesise key findings associated with inequalities.ResultsOf 1,929 publications retrieved, 152 studies of various types were included. The most frequently considered dimensions of inequality were gender, age, and ethnicity, whilst social capital, religion, and sexual orientation were least frequently considered. Most studies researched access by measuring "healthcare utilisation", followed by studies that measured "healthcare seeking". Key barriers to access were associated with individuals' "ability to seek" (e.g. stigma and discrimination) and "ability to reach" (e.g. availability of services). Almost half of the studies used routinely collected patient data, and only 16% of studies reported patient and public involvement.ConclusionsLittle appears to have changed in the nature and extent of inequalities, suggesting that mental health services have not become more accessible. Actions to reduce inequalities should address barriers to population groups' abilities to seek and reach services such as stigma-reducing interventions, and re-designing services and pathways. Significant benefits exist in using routinely collected patient data, but its limitations should not be ignored. More theoretically informed research, using a holistic measurement of access, is needed in this area.Review registrationhttps://doi.org/10.17605/OSF.IO/RQ5U7 .

Project description:ImportanceDespite the existing country-specific strategies tackling social inequalities in visual health in adults, little is known about trends in visual function in childhood and its association with social position.ObjectiveTo investigate the distribution of childhood visual function in the United Kingdom and associations with early-life social position between 1961 and 1986, a period of significant social change.Design, setting, and participantsLongitudinal cohort study using harmonized data sets from the British 1946, 1958, and 1970 national birth cohorts. In total, 14 283 cohort members with complete data on visual acuity at age 15 or 16 years, measured in 1961, 1974, and 1986, respectively, for each cohort, and social position were assessed.Main outcomes and measuresUsing habitual distance visual acuity (with correction if prescribed), participants were assigned to a visual function category ranging from bilateral normal to visual impairment/severe visual impairment/blindness (International Statistical Classification of Diseases, Tenth Revision, Clinical Modification). Distribution of visual function over time and associations with social position (risk ratios [RRs] and 95% confidence intervals) were analyzed.ResultsComplete data were available for 3152 participants (aged 15 years; 53% boys [n = 1660]) in the 1946 Medical Research Council National Survey of Health and Development, 6683 participants (aged 16 years; 51% boys [n = 3420]) in the 1958 National Child Development Study, and 4448 participants (aged 16 years; 48% boys [n = 2156]) in the 1970 British Birth Cohort Study. The proportion of children with bilateral normal vision decreased by 1.3% (95% CI, -5.1% to 2.7%) in 1974 and 1.7% (95% CI, -5.9% to 2.7%) in 1986. The risk of overall impaired vision increased by 1.20 times (95% CI, 1.01-1.43) and the risk of visual impairment/severe visual impairment/blindness by 1.75 times (95% CI, 1.03-2.98) during this period. Girls were consistently at increased risk of all vision impairment categories. Higher social position at birth and in childhood was associated with reduced risk of visual impairment/severe visual impairment/blindness (RR, 0.58; 95% CI, 0.20-1.68) and unilateral impairment (RR, 0.89; 95% CI, 0.72-1.11), respectively.Conclusions and relevanceOur study provides evidence of temporal decline in childhood visual function between 1961 and 1986. Despite the limited power of the analysis owing to the small sample size of those with impaired vision, we found an emergence of a contribution of sociodemographic status to the cohort effect that may be the antecedent of the current picture of childhood blindness. Equally, early-life social position may also have contributed to the current social patterning in visual function in older adults in the United Kingdom. These findings highlight the potential value of targeting children in national ophthalmic public policies tackling inequalities.

Project description:ObjectiveThe coronavirus disease 2019 (COVID-19) pandemic has caused major stress for families and children, particularly in the context of prolonged school closures. Few longitudinal studies are available on young children's mental health, including data both before and during the pandemic. This study examined experiences that might increase risk for mental health problems among caregivers and young children during the COVID-19 pandemic and inequalities driven by pre-pandemic disadvantage.MethodThis prospective, population-based birth cohort study in Pelotas, Brazil, analyzed 2,083 children and caregivers with data from before the pandemic in 2019, when children were 4 years old, and again in 2020, when schools were closed for a long period during the pandemic. Child conduct problems, emotional problems, and hyperactivity-inattention problems were assessed using the Strengths and Difficulties Questionnaire. Family financial hardship, relationship difficulties, caregiver mental health, parenting practices, and child fears and isolation were considered as potential risk factors.ResultsAcross the whole population, the only significant increase in mental health problems from before to during the pandemic was found for maternal depression. However, poorer families were at far greater risk of experiencing serious financial problems, food shortages, increased conflict in adult relationships, parenting problems, and child worries about food availability during the pandemic. In turn, these difficulties were associated with increases in multiple mental health problems for both caregivers and children. Increased child mental health problems were most strongly associated with concurrent maternal anxiety (β > 0.20, p < .001, for each of child conduct, emotional, and hyperactivity problems), maternal depression (β = 0.26, p < .001, for child emotional problems), partner criticism (β = 0.21, p < .001, for child conduct problems), and harsh parenting (β > 0.20, p < .001, for both child conduct and hyperactivity problems). Child worry about COVID-19 was associated with increased emotional problems (β = 0.14, p < .001), but children's isolation was not associated with their mental health.ConclusionOverall, the impact of the COVID-19 pandemic on mental health is a mixed picture, but for families in poverty, marked material and interpersonal difficulties were associated with increases in mental health problems among children and caregivers.
