Background The loss of a child is considered one of the moststressful events in the life of a parent. We hypothesized thatparental bereavement increases the risk of hospital admissionfor a psychiatric disorder, especially for affective disorders.
Methods We studied a cohort of 1,082,503 persons identifiedfrom national registers in Denmark who were born between 1952and 1999 and had at least one child under 18 years of age duringthe follow-up period, from 1970 to 1999. Parents who lost achild during follow-up were categorized as "bereaved" from thedate of death of the child.
Results As compared with parents who did not lose a child, parentswho lost a child had an overall relative risk of a first psychiatrichospitalization for any disorder of 1.67 (95 percent confidenceinterval, 1.53 to 1.83). Bereaved mothers had a higher relativerisk of being hospitalized for any psychiatric disorder thanbereaved fathers (relative risks, 1.78 [95 percent confidenceinterval, 1.60 to 1.98] and 1.38 [95 percent confidence interval,1.17 to 1.63], respectively; P value for interaction, 0.01).The relative risks of hospitalization specifically for affectivedisorders were 1.91 (95 percent confidence interval, 1.59 to2.30) and 1.61 (95 percent confidence interval, 1.15 to 2.27)for bereaved mothers and fathers, respectively. Among mothers,the relative risk of being hospitalized for any psychiatricdisorder was highest during the first year after the death ofthe child but remained significantly elevated five years ormore after the death.
Conclusions The risk of psychiatric hospitalization was increasedamong parents, especially mothers, who lost a child.
