Alcohol-related mortality following the loss of a child: a register-based follow-up study from Norway

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.

Losing a child to adolescent cancer: A register-based cohort study of psychotropic medication use in bereaved parents

PURPOSE

To investigate the short- and long-term risk of psychotropic medication use in parents who lose a child to cancer diagnosed in adolescence.

METHODS

This is a Swedish nationwide register-based study including 184 bereaved mothers and 184 bereaved fathers of 184 children diagnosed with cancer in adolescence. Logistic regression analyses, adjusted for sociodemographic characteristics and history of mental health problems, were performed to estimate risk of a prescription of psychotropic medication (anxiolytics, hypnotics/sedatives, antidepressants) in cancer-bereaved parents from 1 year before to 5 years after the child's death, with a general population sample of non-bereaved parents (n = 3291) as referents.

RESULTS

At the year of the child's death, 28%-36% of mothers and 11%-20% of fathers had a prescription of anxiolytics, hypnotics/sedatives or antidepressants. The corresponding percentages for non-bereaved mothers and fathers were 7%-12% and 4%-7%, respectively. Compared to non-bereaved mothers, bereaved mothers showed higher odds of prescriptions from 1 year before up to four (anxiolytics) and 5 years (hypnotics/sedatives and antidepressants) after the child's death. Bereaved fathers showed higher odds than non-bereaved fathers of prescriptions from 1 year before up to the year of (anxiolytics and hypnotics/sedatives) and 1 year after (antidepressants) the child's death. No differences in odds between bereaved and non-bereaved fathers were found at 2 years after the child's death. Being unmarried, born outside Sweden, and having a history of mental health problems were associated with higher odds of prescribed medications.

CONCLUSIONS

Indicative of mental health problems of clinical importance, cancer-bereaved parents had a higher prevalence of use of psychotropic medication. A decrease in medication use was evident with time, but still at 5 years after the child's death mothers displayed a higher use while fathers showed no difference to non-bereaved fathers after 2 years.

The impact of daylight on suicide rates

Since Durkheim and Morselli found a spring peak in suicides in the late 19th century, researchers have presented possible explanations, including daylight variation, for this seasonal pattern. Our identification strategy exploits the idiosyncratic variation in daylight within Norwegian regions, arising from the country's substantial latitudinal range. We use full population data for a period of 45 years in a pre-registered research design. We find a small and non-significant relationship: One extra hour of daylight increases the suicide rate by merely 0.75 % (95 % CI: -0.4 % to 1.9 %).
