Offspring death and subsequent psychiatric morbidity in bereaved parents: addressing mechanisms in a total population cohort

Work-related consequences of losing a child with cancer: A nationwide population-based cohort study

BACKGROUND

Parents who lose a child are at increased risk of impaired mental health, which may negatively affect their work ability. The aims of this study were to examine the risk for reduced labor market affiliation in parents who lost a child with cancer compared to a matched parent cohort, and factors associated with the bereaved parents' labor market affiliation.

METHODS

We conducted a nationwide population-based cohort study using Danish registry data. We followed bereaved parents (n = 1609) whose child died with cancer at age less than 30 during 1992-2020, and a matched, population-based sample of parents (n = 15,188) of children with no history of childhood cancer. Cox proportional hazard models and fractional logit models were performed separately for mothers and fathers.

RESULTS

Cancer-bereaved mothers had an overall increased risk of long-term sick leave (hazard ratio [HR] = 1.62; 95% confidence interval [CI]: 1.48-1.77), unemployment (HR = 1.53; CI: 1.37-1.70), and lower odds of working in the first 2 years following the loss (odds ratio [OR] = 0.44; CI: 0.39-0.49), while bereaved fathers had lower odds of working (OR = 0.65; CI: 0.53-0.79), and increased risk of permanently reduced work ability (HR = 1.29; 95% CI: 1.01-1.66), compared to the matched cohort of parents of cancer-free children. Younger parental age, lower education, and being a single parent were identified as the main determinants of the bereaved parents' reduced labor market affiliation.

CONCLUSIONS

Cancer-bereaved parents are at increased risk of reduced labor market affiliation, compared with a matched, population-based sample of parents. Certain groups of bereaved parents may be at particularly high risk, and targeted bereavement interventions are warranted.

All-Cause and Cause-Specific Mortality in Parents After the Death of a Child in Taiwan: A Population-Based Cohort Study

OBJECTIVE

Research from Western countries suggests that there is an increase in mortality in parents bereaved by the death of a child. Few studies have investigated this issue in a non-Western context. We explored the impact of the death of a child on parental mortality in Taiwan.

METHOD

By linking population-based national registers, we followed the 2004-2014 birth cohort ( N = 2,083,972) up until 2016. A total of 11,755 child deaths were identified. For each deceased child, four living children matched on age and sex were randomly selected; their parents were the comparison group. We used Cox proportional hazards regression models to compare the mortality risk of bereaved parents with the comparison group up until 2017.

RESULTS

Overall mortality risk was increased in parents who experienced the death of a child; the risk was higher in bereaved mothers (adjusted hazard ratio = 4.91, 95% confidence interval = 3.96-6.09) than fathers (adjusted hazard ratio = 1.82, 95% confidence interval = 1.55-2.13). The risk did not differ according to the sex of the child, but parents whose children died of unexpected causes (i.e., suicide/accidents/violence) were at greater risk than those dying of other causes. Risk was higher when the child was older than 1 year at the time of death than for deaths before age 1 year.

CONCLUSIONS

Parents who lost a child were at increased mortality risk in this East Asian population. Special attention should be paid to the health of bereaved parents and explore the pathways leading to their risk.

Death of a child, religion, and mental health in later life

BACKGROUND AND OBJECTIVES

The death of a child may be one of the most stressful events for parents to experience. This study aims to assess how the death of a child prior to midlife is associated with the mental health of parents in later life, and how this association is contingent upon religious belief in a divine plan.

RESEARCH DESIGN AND METHODS

Using data from aging parents (aged 65 and older) in the six waves (2006-2016) of the Health and Retirement Study (HRS), we conducted negative binomial regression analyses to examine the main effects of the death of a child prior to midlife on late-life depressive symptoms, and the buffering effect of religious beliefs on this main effect (N = 8,248). Growth curve modeling was used to analyze the trajectories of depressive symptoms (Obs. = 31,088).

RESULTS

Experiencing the death of a child prior to midlife is positively associated with depressive symptoms among older adults. Yet, the association is mitigated among respondents who exhibit a high level of belief in a divine plan at baseline. Further, a gradual decline in the number of depressive symptoms over time was observed among the bereaved parents who reported a high level of belief in a divine plan.

DISCUSSION AND IMPLICATIONS

Belief in a divine plan has a protective effect on older adults who cope with the aftermath of child loss. The findings in the study advance our knowledge about the complex interrelationships among stress, religion, and mental health in later life.

Risks of suicide among family members of suicide victims: A nationwide sample of South Korea

OBJECTIVE

Identifying the risks of completed suicide in suicide survivors is essential for policies supporting family members of suicide victims. We aimed to determine the suicide risk of suicide survivors and identify the number of suicides per 100,000 population of suicide survivors, bereaved families of traffic accident victims, and bereaved families with non-suicide deaths.

METHODS

This was a nationwide population-based cohort study in South Korea. The data were taken from the Korean National Health Insurance and Korea National Statistical Office between January 2008 and December 2017. The relationship between the decedent and the bereaved family was identified using the family database of the National Health Insurance Data. Age and gender were randomly matched 1:1 among 133,386 suicide deaths and non-suicide deaths. A proportional hazard model regression analysis was conducted after confirming the cumulative hazard using Kaplan-Meier curves to obtain the hazard ratio (HR) of completed suicide in suicide survivors.

RESULTS

Using 423,331 bereaved families of suicide victims and 420,978 bereaved families of non-suicide deaths as the control group, HR of completed suicide in suicidal survivors was found to be 2.755 [95% confidence limit (CL): 2.550-2.977]. HR for wives committing suicide after husbands' suicide was 5.096 (95% CL: 3.982-6.522), which was the highest HR among all relationships with suicide decedents. The average duration from suicide death to suicide of family members was 25.4 months. Among suicide survivors, the number of suicides per 100,000 people was 586, thrice that of people in bereaved families of traffic accident victims and in bereaved families of non-suicide deaths.

CONCLUSION

The risk of completed suicide was three times higher in suicide survivors than in bereaved families with non-suicide deaths, and it was highest in wives of suicide decedents. Thus, socio-environmental interventions for suicidal survivors must be expanded.

The Grief of Parents After the Death of a Young Child

Research demonstrates that severe forms of grief and grief-related pathology exist in the general population. Less attention, however, has been paid to the grief of parents following the death of a young, dependent child. In this review, we summarize a search of Pubmed, PsycINFO and Web of Science from 1995 to 2017, using the terms 'parental complicated grief', 'parental traumatic grief', and 'parent Prolonged Grief Disorder', specifically addressing parental grief and identified risk factors for complicated or prolonged grief. Forty-two studies met criteria and indicate a significant burden of complicated or prolonged grief in parents of children dying from virtually any cause. It appears that the empiric literature is undermined by great variability, including the composition of samples, the causes of death studied, the psychometric measures used, and post-loss intervals. We conclude that the uniform severity of grief experiences following the death of a young child is potentially a distinct subtype of grief, deserving of attention in its own right in future research and diagnostic formulations.

Fatal intentional drowning in Australia: A systematic literature review of rates and risk factors

INTRODUCTION

Unintentional drowning deaths are only part of the drowning profile, with little attention being paid to intentional drowning in Australia. Strategies for the prevention of intentional drowning deaths are likely to be different from unintentional. Quality documentation, analysis and dissemination of intentional deaths data is crucial for developing appropriate strategies for prevention.

OBJECTIVE

To conduct a systematic literature review to investigate the mortality rates and risk factors of intentional drowning deaths in Australia.

METHODS

A systematic search guided by PRISMA was performed using Ovid MEDLINE, CINAHL, PsycINFO (ProQuest), Scopus, Google Scholar, and BioMed Central databases to locate relevant original research articles published between 2007 and 2018.

RESULTS

Ten papers reporting the mortality rates and risk factors of intentional drowning deaths in Australia published between 2007 and 2018, with study periods of the included articles spanning from 1907 to 2012, were reviewed. Most studies investigated suicidal drowning deaths in Australia, none reported homicidal drowning deaths. The downward trend of fatal suicide drowning was identified in Australia. The annual rate of intentional drowning between 1994 and 2012 can be inferred from eight studies, ranging from 0.06 to 0.21 for nation-wide mortality rates. The highest annual state-wide mortality rate was identified in the state of Queensland, ranging from 0.02 to 0.11 per 100,000 individuals. Of four studies examining the risk factors of fatal intentional drowning in Australia, being of older age groups, being female, and the presence of substance use were identified as important factors for suicidal drowning deaths. The national-scale proportion of suicide drowning in Australia, ranging from 2% to 3% of all intentional self-harm deaths, was also identified.

CONCLUSION

Limited publications reporting the mortality rates and risk factors of intentional drowning deaths in Australia were identified. Being of older age groups and being female were recognised as factors for suicide drowning deaths, and psychoactive substances were widely identified amongst cases. Future research on improving death reporting systems and the legal framework for medico-legal death investigation, along with the investigation of the risk factors of intentional drowning, are required to inform the planning, implementation, and evaluation of prevention interventions for intentional drowning deaths in Australia.

The Effect of Sudden Death Bereavement on the Risk for Suicide

Background: Bereavement after a sudden death is associated with psychiatric sequelae including suicidal ideation and behavior. However, there is still uncertainty about whether bereavement due to suicide increases the risk for suicidal behavior more than bereavement due to other causes of death does. Aims: This study aimed to evaluate suicidal risk among sudden death-bereaved participants and to identify risk factors for suicidality that may be over-represented in those who are suicide-bereaved. Method: In total, 180 adult participants, half of whom had experienced the sudden death of a first-degree relative within the previous 5 years, completed self-report questionnaires assessing suicidal risk, symptoms of depression, somatization, posttraumatic stress disorder (PTSD), complicated grief, perceived social support, and demographic information. Results: Sudden death bereavement was associated with increased suicide risk even after adjusting for psychiatric symptomatology. Within the bereaved groups, the highest risk for suicide was among those bereaved by suicide, with additional contributions from depressive symptomatology, PTSD, somatization, lower perceived social support, and secular religious orientation. Limitations: The study was cross-sectional and bereaved participants had lost their loved one an average of 5 years before the assessment. Conclusion: These results are consistent with the conclusion that suicide bereavement is a risk factor for suicidal behavior.

Parents' Acute Illnesses, Hospitalizations, and Medication Changes During the Difficult First Year After Infant or Child NICU/PICU Death

BACKGROUND AND OBJECTIVES

Infant/child death is described as a most stressful life event; however, there are few reports of effects on parent physical health during the first year after the death. The study's purpose is to examine the patterns of parent acute illnesses, hospitalizations, and medication changes over 1 to 13 months after neonatal intensive care unit (NICU) or pediatric intensive care unit (PICU) infant/child death in 3 racial/ethnic groups.

METHODS

Secondary analyses were conducted with longitudinal data on parent health and functioning 1 to 13 months after infant/child NICU/PICU death. Parents (176 mothers, 73 fathers; 44% Hispanic, 35% black non-Hispanic, and 21% white non-Hispanic) of deceased infants/children were recruited from 4 children's hospitals and state death records. Inclusion criteria-parents understood English or Spanish and had a deceased neonate/child ≤ 18. Exclusion criteria -deceased newborn from multiple gestation pregnancy, child in foster care, child's injury due to suspected abuse, or parent death in illness/injury event. Parents reported numbers and types of acute illnesses, hospitalizations, and medication changes 1 to 13 months postdeath.

RESULTS

Parents' acute illnesses, hospitalizations, and medication changes were greatest between months 1 and 6, with relative quiescence in months 7 to 10, and an increase in months 11 to 13. Mothers (aged 32 ± 7.8 years) reported 300 acute illnesses (primarily colds/flu, headaches, anxiety/depression, and infections) and 89 hospitalizations (primarily infections, chest pain, and gastrointestinal problems). Fathers (aged 37 ± 8.8 years) reported 104 acute illnesses (colds/flu and headaches) and 9 hospitalizations.

CONCLUSION

After infant/child NICU/PICU death, mothers had greater morbidity than fathers, with no significant differences by race/ethnicity. Parents' health needs to be monitored in months 1 to 6 and months 11 to 13, and interventions targeted to parents in these months.

Depression among Parents Two to Six Years Following the Loss of a Child by Suicide: A Novel Prediction Model

Background

Parents who lose a child by suicide have elevated risks of depression. No clinical prediction tools exist to identify which suicide-bereaved parents will be particularly vulnerable; we aimed to create a prediction model for long-term depression for this purpose.

Method

During 2009 and 2010 we collected data using a nationwide study-specific questionnaire among parents in Sweden who had lost a child aged 15-30 by suicide in years 2004-2007. Current depression was assessed with the Patient Health Questionnaire (PHQ-9) and a single question on antidepressant use. We considered 26 potential predictors assumed clinically assessable at the time of loss, including socio-economics, relationship status, history of psychological stress and morbidity, and suicide-related circumstances. We developed a novel prediction model using logistic regression with all subsets selection and stratified cross-validation. The model was assessed for classification performance and calibration, overall and stratified by time since loss.

Results

In total 666/915 (73%) participated. The model showed acceptable classification performance (adjusted area under the curve [AUC] = 0.720, 95% confidence interval [CI] 0.673-0.766), but performed classification best for those at shortest time since loss. Agreement between model-predicted and observed risks was fair, but with a tendency for underestimation and overestimation for individuals with shortest and longest time since loss, respectively. The identified predictors include female sex (odds ratio [OR] = 1.84); sick-leave (OR = 2.81) or unemployment (OR = 1.64); psychological premorbidity debuting during the last 10 years, before loss (OR = 3.64), or more than 10 years ago (OR = 4.96); suicide in biological relatives (OR = 1.54); with non-legal guardianship during the child’s upbringing (OR = 0.48); and non-biological parenthood (OR = 0.22) found as protective.

Conclusions

Our prediction model shows promising internal validity, but should be externally validated before application. Psychological premorbidity seems to be a prominent predictor of long-term depression among suicide-bereaved parents, and thus important for healthcare providers to assess.
