Cause of parental death and child's health and education: The role of parental resources

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.

Adolescents' primary care consultations before and after parental suicide: evidence from population-wide data

Parental bereavement is associated with distress and poorer long-term outcomes among adolescents. Adolescents who lose a parent to suicide fare worse than their peers even before bereavement. Based on the current literature, we cannot distinguish such initial differences from the medium and long-term effect of parental suicide. We study the impact of parental suicide on adolescents' General Practitioner visits for mental health or psychosocial reasons. Within-individual models account for time-invariant differences between the bereaved and non-bereaved. We investigate if effects differ from the impact of parental death from other causes, and vary with sex and socioeconomic background. Full population data on Norwegian residents aged 10-19 in the period 2006-2015 are drawn from registers (N = 1 405 suicide bereaved, 12 982 bereaved by other causes, and 1 182 819 non-bereaved controls). Records include data on use of health services, parental mortality, and sociodemographic characteristics of parent and child. Mental health consultations increase gradually in the quarters leading up to the parental suicide, significantly more for girls than for boys. Two years prior to bereavement, 2.4% of the subsequently suicide bereaved have a mental health consultation in any given quarter. In the year of bereavement, this increases with 6% points. Health care workers should be aware that boys are less likely to turn to their GP for support before parental bereavement from suicide.

A hard pill to swallow? Parental health shocks and children's mental health

Based on comprehensive administrative health record data from Austria, this study examines how children's mental health responds to a severe parental health shock. To account for the endogeneity of a serious parental illness, our sample is restricted to children who experience the health shock of a parent at some point in time and we exploit the timing of shocks in a dynamic DID setting. We find a positive causal effect of parental health shocks on children's mental health care utilization. Affected children have higher medical attendance for the treatment of mental illnesses, consume more psychotropic drugs, and are more likely to be hospitalized with mental and behavioral disorders. A significant increase in the utilization of antidepressants, anxiolytics, and sedatives can be observed for older children, girls and children with a white-collar family background. Our findings have important policy implications for children's access to psychotherapies and mental health care after experiencing a traumatic household event.

Bosnian Paternal War Orphans: Mental Health in Postwar Time

ABSTRACT

More research on the medium- and long-term effects of childhood exposure to war, including orphanhood, is needed. We compared 50 orphans 1 who lost their father during the war in Bosnia and Herzegovina (1992-1995) and 50 age- and sex-matched adolescents from two-parent families during 2011-2012 in terms of sociodemographic characteristics, behavioral/emotional problems, depression, resilience, maternal mental health, and perceived social support. The two groups differed on sociodemographic factors, that is, number of children, family composition, income, school grades, and refugeehood. Paternal war orphans did not differ in terms of adolescent mental health and resilience from their nonorphaned peers, controlling for sociodemographic variables. The mothers of orphans had comparably more posttraumatic psychopathology. As for perceived resources for social support, orphans identified those comparably more often among distant relatives and in the community, that is, religious officials and mental health professionals, and less often among siblings, paternal grandparents, paternal and maternal uncles/aunts, school friends and teachers. Our findings suggest that contextual factors may play an important role in orphans' postwar mental health.

Examining common and distinct contributions to the etiology of suicide attempt and reattempt

This study examined the extent to which the genetic and environmental characteristics of having a first versus a second suicide attempt (SA) are common or specific. We evaluated the direct pathway between these phenotypes and the role of specific risk factors. From Swedish national registries, two subsamples of individuals born between 1960 and 1980 were selected (1,227,287 twin-sibling pairs and 2,265,796 unrelated individuals). First, a twin-sibling model was fit to evaluate the genetic and environmental risk factors related to first and second SA. The model also included a direct path between first and second SA. Second, an extended Cox proportional hazards model (PWP) was used to evaluate the risk factors related to first versus second SA. In the twin-sibling model, suicide reattempt was strongly related to first SA (β = 0.72). The total heritability for the second SA was estimated at 0.48, with 45.80% unique to this second SA. The total environmental influence for the second SA was 0.51, with 50.59% unique. In the PWP model, we found that childhood environment, psychiatric disorders, and selected stressful life events were related to both first and second SA, potentially reflecting common genetic and environmental factors. Other stressful life events were associated with first but not second SA in the multivariable model, suggesting their specificity in explaining the first occurrence of SA but not its recurrence. Specific risk factors related to second SA need to be further explored. These findings have important implications for describing the pathways toward suicidal behavior and identifying individuals at risk for multiple SA.

When young children grieve: Supporting daycare children following bereavement-A parent's perspective

Thirteen parents who lost the mother or father to their child were interviewed, using semi-structured interviews. Participants reflect on their young children's (3-6) grief, support needs, and what they learned from this trying time. The event scarred all participants. While some moved on, others were still struggling years after. The study uncovers difficulties associated with informing a young child, with a limfited understanding of illness and loss, in a life-situation where parents themselves are clinging to hope. While support is available from daycare, it can be better organised and structured. Proactive support that assists the child through illness and death relieves the parental care burden.

Global and regional estimates of orphans attributed to maternal cancer mortality in 2020

Despite women being disproportionally affected by cancer deaths at young ages, there are no global estimates of the resulting maternal orphans, who experience health and education disadvantages throughout their lives. We estimated the number of children who became maternal orphans in 2020 due to their mother dying from cancer in that year, for 185 countries worldwide and by cause of cancer-related death. Female cancer deaths-by country, cancer type and age (derived from GLOBOCAN estimates)-were multiplied by each woman's estimated number of children under the age of 18 years at the time of her death (fertility data were derived from United Nations World Population Prospects for birth cohort), accounting for child mortality and parity-cancer risk associations. Globally, there were 1,047,000 such orphans. Over half of these were orphans due to maternal deaths from breast (258,000, 25%), cervix (210,000, 20%) and upper-gastrointestinal cancers (136,000, 13%), and most occurred in Asia (48%: India 15%, China 10%, rest of Asia 23%) and Africa (35%). Globally, there were 40 new maternal orphans due to cancer per 100,000 children, with a declining trend with a higher Human Development Index (range: 121 in Malawi to 15 in Malta). An estimated 7 million children were prevalent maternal orphans due to cancer in mid-2020. Accelerating the implementation of the World Health Organization's cervical and breast cancer initiatives has the potential to avert not only millions of preventable female cancer deaths but also the associated, often-overlooked, intergenerational consequences of these deaths.

Links Between Maternal Cardiovascular Disease and the Health of Offspring

Maternal cardiovascular disease (CVD) during pregnancy is on the rise worldwide, as both more women with congenital heart disease are reaching childbearing age, and conditions such as diabetes, hypertension, and obesity are becoming more prevalent. However, the extent to which maternal CVD influences offspring health, as a neonate and later in childhood and adolescence, remains to be fully understood. The thrifty phenotype hypothesis, by which a fetus adapts to maternal and placental changes to survive a nutrient-starved environment, may provide an answer to the mechanism of maternal CVD and its impact on the offspring. In this narrative review, we aim to provide a review of the literature pertaining to the impact of maternal cardiovascular and hypertensive disease on the health of neonates, children, and adolescents. This review demonstrates that maternal CVD leads to higher rates of complications among neonates. Ultimately, our review supports the hypothesis that maternal CVD leads to intrauterine growth restriction (IUGR), which, through the thrifty phenotype hypothesis and vascular remodelling, can have health repercussions, including an impact on CVD risk, both in the immediate newborn period as well as later throughout the life of the offspring. Further research remains crucial in elucidating the mechanism of maternal CVD long-term effects on offspring, as further understanding could lead to preventive measures to optimise offspring health, including modifiable lifestyle changes. Potential treatments for this at-risk offspring group could mitigate risk, but further studies to provide evidence are needed.
