The Death of a Child and Parents' Psychological Distress in Mid to Later Life: Racial/Ethnic Differences in Exposure and Vulnerability

Familial Loss of a Loved One and Biological Aging: NIMHD Social Epigenomics Program

Importance

The link between familial loss of a loved one and long-term health decline is complex and not fully understood.

Objective

To test associations of losing a parent, sibling, child, or partner or spouse with accelerated biological aging.

Design, Setting, and Participants

Data from the National Longitudinal Study of Adolescent to Adult Health, a US population-based longitudinal cohort study, were analyzed. Participants were enrolled from 1994 to 1995 for wave 1, while in grades 7 to 12, and followed up through wave 5 in 2018. The study analyzed participant reports of loss collected at each wave from 1 to 5 over 24 years and used a banked wave 5 blood sample for subsequent DNA methylation testing and epigenetic clock calculation from 2018 to 2024. Data were analyzed from January 2022 to July 2024.

Exposure

Loss of biological parents or parental figures, partners or spouses, siblings, or children at waves 1 to 3 or during childhood, adolescence (aged <18 years), or adulthood at wave 4 to wave 5 (aged 18-43 years).

Main Outcomes and Measures

Biological aging assessed from blood DNA methylation using the Horvath, PhenoAge, GrimAge, and DunedinPACE epigenetic clocks at wave 5.

Results

Data from 3963 participants were analyzed, with a weighted mean (range) age of 38.36 (36.78-39.78) years at wave 5; 2370 (50.3%) were male, 720 (15.97%) were Black, 400 (8.18%) were Hispanic, and 2642 (72.53%) were White. Nearly 40% of participants experienced loss by wave 5 when they were aged 33 to 43 years, and participants who were Black (379 participants [56.67%]), Hispanic (152 participants [41.38%]), and American Indian (18 participants [56.08%]) experienced a greater proportion of losses compared with White participants (884 participants [34.09%]). Those who experienced 2 or more losses tended to have older biological ages for several of the clocks (PhenoAge β = 0.15; 95% CI, 0.02 to 0.28; GrimAge β = 0.27; 95% CI, 0.09 to 0.45; DunedinPACE β = 0.22; 95% CI, 0.10 to 0.34) compared with those with no losses. In contrast, there were no associations with 2 or more losses for the Horvath clock (β = -0.08; 95% CI, -0.23 to 0.06).

Conclusions and Relevance

This study reveals associations between various measures of loss experienced from childhood to adulthood and biological aging in a diverse sample of the US population. These findings underscore the potentially enduring impact of loss on biological aging even before middle age and may contribute to understanding racial and ethnic disparities in health and mortality.

Intergenerational ties in late life

At the turn of the twenty-first century, scholars predicted that ties between aging parents and grown offspring would grow in prominence and become the primary relationship for many adults. These ties are often emotionally complex, in both positive and negative ways, and resource rich with regard to support. Contact between generations has become both more frequent in the form of coresidence and less frequent due to high rates of migration. Support exchanges are often high in this tie involving, emotional, financial and practical assistance. A burgeoning literature addresses the implications of loss of this tie via death or estrangement. Collectively, recent studies address strengths of these ties, and explanations for their absence when that occurs.

The death of an adult child and trajectories of parental depressive symptoms: A gender-based longitudinal analysis

RATIONALE

Despite the existing body of research on the impact of child bereavement, little is known about whether time to the death of an adult child is longitudinally associated with changes in depressive symptoms among older parents.

OBJECTIVE

This study examines (a) trajectories of depressive symptoms before and after the loss of an adult child and (b) whether these trajectories differ across parent-child gender dyads (father-son, father-daughter, mother-son, and mother-daughter).

METHODS

Using eight waves of the Korean Longitudinal Study of Ageing (KLoSA), this study employs fixed effects models to mitigate potential bias due to unobserved individual-level heterogeneity. Gender-stratified fixed effects models were estimated to investigate potential heterogeneity in the trajectories of depressive symptoms by parent-child gender dyads.

RESULTS

The result of this study revealed that depressive symptoms increased within the first year following the loss of an adult child among bereaved parents. Within a year of the loss of a child, both mothers and fathers experienced an increase in depressive symptoms. However, only fathers experienced lasting effects for up to two years. Different patterns in psychological adjustment to bereavement were observed across different parent-child gender dyads. Among daughter-bereaved fathers, depressive symptoms surged within the first year and persisted even beyond the fourth year of loss. In contrast, for other dyads, only an immediate rise in depressive symptoms within the first year of loss was observed.

CONCLUSIONS

The loss of an adult child increases the depressive symptoms of parents. This study highlights the importance of considering the different trajectories of psychological adjustment to bereavement, particularly based on parent-child gender dyads, when formulating policies for providing psychological support to older parents who have experienced the loss of their child.

"We were made to mourn": A meta-ethnographic synthesis of living through the loss of a child to cancer for Latinx families in the United States

Latinx children with cancer in the United States (US) are more than 50% more likely to die of their cancer compared to non-Latinx White children. Despite this disproportionate likelihood, little is known about the grief experiences of Latinx populations in the US related to the loss of a child including the sociocultural context of this loss experience. We used a meta-ethnographic approach to analyze and synthesize qualitative data across 9 studies related to bereavement and grief in US-based Latinx families following the death of a child. Four key concepts emerged that shape the environment of loss, influence the experience of grief, and affect the related resiliency capacities of Latinx families in the US: (1) immigration context, (2) Latinx cultural influences, (3) social support/familismo, and (4) healthcare inequities. These findings can inform future research and the development of culturally responsive interventions.

Parental Death Across the Life Course, Social Isolation, and Health in Later Life: Racial/Ethnic Disadvantage in the U.S

Bereavement is a risk factor for poor health, yet prior research has not considered how exposure to parental death across the life course may contribute to lasting social isolation and, in turn, poor health among older adults. Moreover, prior research often fails to consider the racial context of bereavement in the United States wherein Black and Hispanic Americans are much more likely than White Americans to experience parental death earlier in life. The present study uses longitudinal data from the Health and Retirement Study (HRS; 1998-2016) to consider linkages of parental death, social isolation, and health (self-rated health, functional limitations) for Black, Hispanic, and White older adults. Findings suggest that exposure to parental death is associated with higher levels of isolation, greater odds of fair/poor self-rated health, and greater odds of functional limitations in later life. Moreover, social isolation partially explains associations between parental bereavement and later-life health. These patterns persist net of psychological distress-an additional psychosocial response to bereavement. Racial inequities in bereavement are central to disadvantage: Black and Hispanic adults are more likely to experience a parent's death earlier in the life course, and this differential exposure to parental death in childhood or young adulthood has implications for racial and ethnic inequities in social isolation and health throughout life.

A Time of Healing: Can Social Engagement After Bereavement Reduce Trajectories of Depression After the Death of a Child?

OBJECTIVES

We work from a stress and life-course perspective to examine the mental health of parents who experienced the death of their child. We examine whether mental health eventually returns to pre-bereavement levels and how social engagement after bereavement may shape the recovery process of depressive symptoms.

METHODS

We analyze discontinuous growth curve models to assess the association between a child's death and trajectories of parents' depressive symptoms from the 1998-2016 Health and Retirement Study. The sample includes 16,182 parents aged 50 years and older.

RESULTS

Those who transitioned to bereavement experienced an elevation in depressive symptoms and a relatively long recovery time (e.g., 7 years) to their pre-bereavement mental health in our findings. However, when engaging in volunteer work after their loss, depressive symptoms reduce more quickly to their pre-bereavement levels. Volunteering offsets up to 3 years of the negative consequences of child loss.

DISCUSSION

The death of a child is a traumatic event with extensive health consequences, but research should more fully examine the dynamic nature and potential mitigation of these health consequences over time. Our findings expand the temporal lens to encompass healing processes after bereavement, incorporating the importance of social engagement.

Differential sensitivity to adversity by income: Evidence from a study of Bereavement

Adverse life events are often understood as having negative consequences for mental health via objective hardships, which are worse for persons with less income. But adversity can also affect mental health via more subjective mechanisms, and here, it is possible that persons with higher income will exhibit greater psychological sensitivity to negative events, for various reasons. Drawing on multiple sociological literatures, this article theorizes potential mechanisms of increasing sensitivity with income. The proposition of differential sensitivity is tested using the strategic case of spousal and parental bereavement among older US adults. The analyses find consistent evidence of increasing sensitivity of depressive symptoms with income. A series of robustness checks indicate that findings are not due to endogenous or antecedent selection. Further, exploratory analyses of mechanisms suggest that higher sensitivity among the affluent was driven by greater expectations and better relationship quality with the deceased. These findings problematize the conceptualization and assessment of human suffering in economically stratified societies.

Social Isolation: An Unequally Distributed Health Hazard

Social isolation is a potent predictor of poor health, mortality, and dementia risk. A great deal of research across national contexts provides causal evidence for these linkages and identifies key explanatory mechanisms through which isolation affects health. Research on social isolation recognizes that some people are more likely than others to be isolated, but over the past several decades, researchers have focused primarily on the consequences of isolation for health rather than a systematic assessment of the social conditions that foster isolation over the life course. In this article, we review the available evidence on inequities in social isolation and develop a conceptual framework to guide future research on structural systems that fuel social isolation over the life course. Future work in this area has the potential to identify root causes of inequality in social isolation, as well as targeted policy levers to reduce isolation in vulnerable populations.

Multiple Family Member Deaths and Cardiometabolic Health among Black and White Older Adults

Although the bereavement literature is voluminous, we know very little about how exposure to multiple family member deaths across the life course shapes health trajectories as people age and whether unequal exposure to bereavement contributes to racial inequities in cardiometabolic health. We use longitudinal data from the Health and Retirement Study (1992-2016) to consider how multiple family member deaths before midlife shape trajectories of cardiometabolic health after age 50 for Black and white adults (n = 22,974). Results show that multiple family member deaths prior to age 50 are associated with more cardiometabolic conditions at age 50 and a faster increase in conditions with advancing age. Moreover, Black adults are significantly disadvantaged by a greater risk of bereavement and more cardiometabolic conditions regardless of bereavement status. The life course trauma of exposure to multiple family member deaths uniquely contributes to the cardiometabolic risk of Black Americans.

"Outside the Skin": The Persistence of Black-White Disparities in U.S. Early-Life Mortality

Research on Black-White disparities in mortality emphasizes the cumulative pathways through which racism gets "under the skin" to affect health. Yet this framing is less applicable in early life, when death is primarily attributable to external causes rather than cumulative, biological processes. We use mortality data from the National Vital Statistics System Multiple Cause of Death files and population counts from the Surveillance, Epidemiology, and End Result Program to analyze 705,801 deaths among Black and White males and females, ages 15-24. We estimate age-standardized death rates and single-decrement life tables to show how all-cause and cause-specific mortality changed from 1990 to 2016 by race and sex. Despite overall declines in early-life mortality, Black-White disparities remain unchanged across several causes-especially homicide, for which mortality is nearly 20 times as high among Black as among White males. Suicide and drug-related deaths are higher among White youth during this period, yet their impact on life expectancy at birth is less than half that of homicide among Black youth. Critically, early-life disparities are driven by preventable causes of death whose impact occurs "outside the skin," reflecting racial differences in social exposures and experiences that prove harmful for both Black and White adolescents and young adults.
