Abstract

Purpose

Although childhood traumatic experiences are recognized as important determinants for adolescent psychiatric health in general, our objective was to explore the specific influence of childhood bereavement on the stress resilience development trajectory.

Methods

In this national register-based cohort study, we identified 407,639 men born in Sweden between 1973 and 1983, who underwent compulsory military enlistment examinations in late adolescence, including measures of psychological stress resilience. We defined exposure as loss of a first-degree family member in childhood, and estimated relative risk ratios (RRRs) for reduced (moderate or low), compared with high, stress resilience with 95% confidence intervals (CIs) using multinomial logistic regression.

Results

Loss of a parent or sibling in childhood conferred a 49% increased risk of subsequent low stress resilience (RRR, 1.49, 95% CI, 1.41–1.57) and an 8% increased risk of moderate stress resilience (RRR, 1.08, 95% CI, 1.03–1.13) in late adolescence. There was also a graded increase in risk with increasing age at loss; teenagers were at higher risk for low resilience (RRR, 1.64, 95% CI, 1.52–1.77) than children aged 7–12 (RRR, 1.47, 95% CI, 1.34–1.61) and 6 years (RRR, 1.16 95% CI, 1.02–1.32). The excess risk was observed for all causes of death, including suicide and unexpected deaths as well as deaths due to other illnesses. The associations remained after exclusion of parents with a history of hospitalization for psychiatric diagnoses.

Conclusions

The long-term consequences of childhood bereavement may include lower stress resilience in late adolescence.

National registers

All residents in Sweden have a unique National Registration Number, recorded at birth or immigration, which enables record linkages in national registers. We acquired birth date, sex, country of birth, and child-parent linkages from the Swedish Multi-Generation Register, socioeconomic information from The Education Register and the Swedish Population and Household Census, and data on birth variables from the Medical Birth Register. Date and causes of death were obtained from the Causes of Death

Results

The characteristics of the young men participating in the study are presented in Table 1. Overall, 21.6% were classified as having high stress resilience, 56.3% moderate stress resilience, and 22.1% low stress resilience. Men with low stress resilience were more likely to be underweight or obese, and perform poorer with regard to cognitive ability and physical fitness, compared with individuals with moderate or high stress resilience. A lower proportion of parents with university level

Discussion

In this large population-based study, based on prospectively collected data, we found an association between loss of a close relative in childhood and low stress resilience in late adolescence. We observed higher magnitude associations for losses occurring beyond preschool age, after loss of a father, and for losses caused by external causes (such as accidents and suicide). In contrast, no association was observed for children of women who experienced loss during pregnancy.

      Citation Excerpt :

      We also found that severe childhood abuse was associated with lower levels of resilience in adulthood, reflecting that resilience could be a dynamic personality trait that might alter in response to environmental factors (Wagnild & Young, 1993). It was reported that experiences of childhood trauma could lead individuals less resilient in later life (Campbell-Sills et al., 2009; Fischer et al., 2014; Kennedy et al., 2018). Experiences of childhood that are too severe to manage may lead to stress sensitization and increase vulnerability to stressful events (Southwick et al., 2005).
