Families who have contact with child welfare services (CWS) often face a number of socioeconomic and psychosocial challenges, which may have led to the parents being unable to adequately care for their children. To date, understandings regarding the parents’ socioeconomic and psychosocial conditions after the placement of a child are limited. A database search of PubMed, Sociological abstract, CINAHL, PsycINFO, Scopus, and Web of Science was performed to identify studies that investigate the socioeconomic and psychosocial conditions of parents with children in OHC published between January 1, 1980 and November 20, 2021. Of 19,750 screened articles, 51 qualitative articles met the inclusion criteria. Emerging themes relating to parents’ subjective experiences were synthesized into three overarching themes: (1) experiencing a loss, (2) living a fragile reality, and (3) opportunity for change. The results demonstrate that more support is needed for parents as the placement of their child is a challenging time that places stress on their psychosocial and socioeconomic conditions, no matter the reason for placement. With the right support, positive adaptations could be possible.

Background: “Child maltreatment is a leading cause of health inequality” according to a leading WHO report. This statement is often assumed, yet, the size of the contribution of childhood adversity to the adult socioeconomic gradient in mortality remains unknown. Inequalities in mortality have mostly been investigated by taking adult conditions as a starting point. The objective of this study is to quantify how much of the socioeconomic gradient in adult life expectancy is associated with childhood adversity. Methods: Drawing on a 1953 birth cohort from Stockholm (n = 14 210), we compared inequalities in adult mortality within the full cohort to a counterfactual scenario where individuals with a history of childhood adversity (indicated by involvement with child welfare services) experienced the mortality rates of those achieving the same adult socioeconomic position, but with no history of childhood adversity. The socioeconomic gradient across education and income quintiles (attained by age 29) is measured by the slope index of inequality of temporary life expectancy (ages 29–67). Results: The counterfactual scenario attenuated the education gradient by 40 percent for men and 54 percent for women. Similarly, inequalities by income were reduced in the counterfactual scenario by 49 percent for men and 47 percent for women. Interpretation: These results support that childhood adversity is an important determinant of inequalities in mortality. The size of their contribution is equivalent to established behavioural risk factors. Taking a life course approach might provide important policy entry points to mitigate health inequalities.

Background: While individuals who were separated from their biological family and placed into the care of the state during childhood (out-of-home care) are more prone to developing selected adverse health problems in adulthood, their risk of cardiovascular disease is uncertain. Our aim was to explore this association by pooling published and unpublished results from prospective cohort studies. Methods: We used two approaches to identifying relevant data on childhood care and adult cardiovascular disease (PROSPERO registration CRD42021254665). First, to locate published studies, we searched PubMed (Medline) until November 2023. Second, with the objective of identifying unpublished studies with the potential to address the present research question, we scrutinised retrieved reviews on childhood out-of-home care and other adult health outcomes. Included studies were required to satisfy three criteria: a cohort study in which the assessment of care was made prospectively pre-adulthood (in the avoidance of recall bias); data on an unexposed comparator group were available (for the computation of relative risk); and a diagnosis of adult cardiovascular disease events (coronary heart disease, stroke, or their combination) had been made (as opposed to risk factors only). Collaborating investigators provided study-specific estimates which were aggregated using random-effects meta-analysis. The Newcastle-Ottawa Scale was used to assess individual study quality. Findings: Twelve studies (2 published, 10 unpublished) met the inclusion criteria, and investigators from nine provided viable results, including updated analyses of the published studies. Studies comprised 611,601 individuals (301,129 women) from the US, UK, Sweden, Finland, and Australia. Five of the nine studies were judged to be of higher methodological quality. Relative to the unexposed, individuals with a care placement during childhood had a 51% greater risk of cardiovascular disease in adulthood (summary rate ratio after age- and sex-adjustment [95% confidence interval]: 1.51 [1.22, 1.86]; range of study-specific estimates: 1.07 to 2.06; I2 = 69%, p = 0.001). This association was attenuated but persisted after adjustment for socioeconomic status in childhood (8 studies; 1.41 [1.15, 1.72]) and adulthood (9 studies, 1.29 [1.11, 1.51]). Interpretation: Our findings show that individuals with experience of out-of-home care in childhood have a moderately raised risk of cardiovascular disease in adulthood.

Background: Social inequalities in multimorbidity may occur due to familial and/or individual factors and may differ between men and women. Using population-based multi-generational data, this study aimed to (1) assess the roles of parental and individual education in the risk of multimorbidity and (2) examine the potential effect modification by sex. Methods: Data were analysed from 62 060 adults aged 50+ who participated in the Survey of Health, Ageing and Retirement in Europe, comprising 14 European countries. Intergenerational educational trajectories (exposure) were High–High (reference), Low–High, High–Low and Low–Low, corresponding to parental–individual educational attainments. Multimorbidity (outcome) was ascertained between 2013 and 2020 as self-reported occurrence of ≥2 diagnosed chronic conditions. Inequalities were quantified as multimorbidity-free years lost (MFYL) between the ages of 50 and 90 and estimated via differences in the area under the standardized cumulative risk curves. Effect modification by sex was assessed via stratification. Results: Low individual education was associated with higher multimorbidity risk regardless of parental education. Compared to the High–High trajectory, Low–High was associated with −0.2 MFYL (95% confidence intervals: −0.5 to 0.1), High–Low with 3.0 (2.4–3.5), and Low–Low with 2.6 (2.3–2.9) MFYL. This pattern was observed for both sexes, with a greater magnitude for women. This effect modification was not observed when only diseases diagnosed independently of healthcare-seeking behaviours were examined. Conclusions: Individual education was the main contributor to intergenerational inequalities in multimorbidity risk among older European adults. These findings support the importance of achieving a high education to mitigate multimorbidity risk.

Life course epidemiology aims to study the effect of exposures on health outcomes across the life course from a social, behavioural, and biological perspective. In this Review, we describe how life course epidemiology changes the way the causes of chronic diseases are understood, with the example of hypertension, breast cancer, and dementia, and how it guides prevention strategies. Life course epidemiology uses complex methods for the analysis of longitudinal, ideally population-based, observational data and takes advantage of new approaches for causal inference. It informs primordial prevention, the prevention of exposure to risk factors, from an eco-social and life course perspective in which health and disease are conceived as the results of complex interactions between biological endowment, health behaviours, social networks, family influences, and socioeconomic conditions across the life course. More broadly, life course epidemiology guides population-based and high-risk prevention strategies for chronic diseases from the prenatal period to old age, contributing to evidence-based and data-informed public health actions. In this Review, we assess the contribution of life course epidemiology to public health and reflect on current and future challenges for this field and its integration into policy making.

Families involved with child welfare services (CWS) often diverge systematically from the general population. They are more likely to live in challenging circumstances characterised by adverse socioeconomic conditions (e.g. poverty) and psychosocial adversities (e.g. mental health problems and substance misuse). Past research has primarily focused on the development and lifelong health and social outcomes of children who have experienced out-of-home care (OHC). However, the separation could also trigger negative emotions and other changes in parents, but much less attention has been paid to the associations between children’s placement and parents’ lives.

This scoping review synthesises results from quantitative studies investigating the socioeconomic and psychosocial outcomes of parents who have experienced the removal of a child into OHC. Six databases were comprehensively searched, with 15 studies selected for inclusion in the review. Studies were conducted among countries of the Organization for Economic Cooperation and Development (OECD) with substantial heterogeneity in the methods and designs, as grouped into three categories: “cross-sectional assessments” (4 studies), “longitudinal assessments” (7 studies) and “pre-post assessment” (4 studies).

To a large extent, studies focus on psychosocial outcomes among mothers. The majority indicate that having a child placed in OHC is associated with the deterioration of psychosocial or socioeconomic outcomes among parents. We may conclude that parents who have experienced the removal of a child are a group that deserves tailored support and counselling. However, further quantitative research into aspects of parents’ lives after children’s OHC placement is needed, particularly with longitudinal designs and more rigorous methods to enable a better understanding of the causes and effects of these associations. This might support the development of targeted and effective interventions for these families.

Background: Literature on outcomes of children in out-of-home care (OHC) is extensive. However, less is known regarding associations of such placements with parental mental health disorders (MHD).

Objective: This study investigated changes in hospitalization rates due to MHD among parents, four years before and after placement of their child in OHC.Participants and settingWe used data on 4067 members (Generation 1) of the RELINK53 cohort (individuals born and living in Sweden in 1953) and their 5373 children (Generation 2) in OHC.

Methods: Using random effects regression models, associations between OHC and MHD were examined separately for fathers and mothers. Nested models were tested exploring associations with parent and child/placement-related factors. Marginal effects were computed to assess mean rates of hospitalization annually.

Results: Overall, mothers had higher mean hospitalization rates than fathers. Compared to the year of placement, hospitalization rates were significantly lower in the four years before placement for mothers (9.9 %, 9.5 %, 10.5 %, 12.1 %, respectively) and fathers (5.9 %, 7.6 %, 8 %, 9.8 %, respectively). Mothers showed highest hospitalization rates at the year of placement (26.6 %), while fathers, one year after placement (13.4 %). Hospitalization rates declined significantly directly after placement among mothers, but an unclear and non-significant pattern of results was found among fathers.

Conclusions: Most parents have higher hospitalization rates at and directly after placement. Potential hypotheses underlying these findings are discussed, including psychosocial gender differences and opportunities to seek care as means of reunification. There is an urgency to develop strategies to better support these parents throughout the process.

Background: Childhood adversity indicated by involvement with child welfare services (ICWS) is associated with increased risks of disease and injuries in young adulthood. It is yet unknown whether such risks are limited to external causes and mental and behavioural disorders or whether they extend beyond early adulthood and to non-communicable diseases (NCDs) with later onset. Moreover, it has not been explored whether ICWS associates with decreased survival prospects following hospitalisation.

Methods: Based on prospective data for a 1953 Stockholm birth cohort (n=14 134), ICWS was operationalised distinguishing two levels in administrative child welfare records (ages 0–19; ‘investigated’ and ‘placed’ in out-of-home care (OHC)). Hospitalisations and all-cause mortality (ages 20–66) were derived from national registers. Hospitalisation records were categorised into external causes and NCDs, and nine subcategories. Negative binomial regression models were used to estimate differences in hospitalisation risks between those with and without experiences of ICWS and Cox survival models to estimate mortality after hospitalisation.

Results: Placement in OHC was associated with higher risks of hospitalisation due to external causes and NCDs and all investigated subcategories except cancers. Risks were generally also elevated among those investigated but not placed. ICWS was further linked to higher mortality risks following hospitalisation.Conclusion Differential risk of morbidity and differential survival may explain inequalities in mortality following childhood adversity. We conclude that the healthcare sector might play an important role in preventing and mitigating the elevated risks of externally caused morbidity, disease and premature mortality observed among those with a history of ICWS.

Previous studies have shown that mental health disorders (MHD) among parents might be an important mechanism in the intergenerational transmission of out-of-home care (OHC). The current study aimed to further study this interplay by investigating the associations between OHC and MHD within and across generations. We used prospective data from the Stockholm Birth Cohort Multigenerational Study (SBC Multigen) on 9033 cohort members (Generation 1; G1) and their 15,305 sons and daughters (Generation 2; G2). By odds ratios of generalised structural equation modelling, we investigated the intergenerational transmission of OHC and MHD, respectively, as well as the association between OHC and MHD within each generation. Second, we examined the associations between OHC and MHD across the two generations. In order to explore possible sex differences, we performed the analyses stratified by the sex of G2. The results showed an intergenerational transmission of OHC, irrespective of sex. Regarding the intergenerational transmission of MHD, it was shown for both sexes although only statistically significant among G2 males. OHC was associated with MHD within both generations; in G2, this association was stronger among the males. While we found no direct association between OHC in G1 and MHD in G2, there was a significant association between MHD in G1 and OHC in G2. The latter was more evident among G2 females than G2 males. We conclude that OHC and MHD seem to be processes intertwined both within and across generations, with some variation according to sex. Although there did not seem to be any direct influences of OHC in one generation on MHD in the next generation, there was some indication of indirect paths going via parental MHD and child OHC.

Previous research has demonstrated a graded relationship between cumulative childhood adversity and adverse later outcomes. Individuals with out-of-home care (OHC) experience constitute a population characterised by both childhood and educational disadvantages. Based on a fifty-year follow-up of a Stockholm cohort born in 1953, the purpose of this study was to examine the associations between cumulative childhood adversity and long-term educational outcomes in this group. The cumulative disadvantage perspective suggests that there would be a negative association, while the disadvantage saturation perspective implies that cumulative adversity would be less consequential for disadvantaged individuals. By means of multigroup path analysis, we furthermore asked whether this association may differ in relation to individuals with child welfare contact (CWC) and to the general population (GP). Adjusting for socioeconomic conditions and cognitive ability, cumulative childhood adversity had a negative influence on midlife educational attainment in the GP. However, it did not seem to influence the educational outcomes of neither OHC experienced individuals nor individuals with other types of CWC. The results of this study thus lend support to the disadvantage saturation perspective. Further studies are needed to explore this relationship.
