TOPLINE:

Children who lost a biological parent to homicide, suicide, or drug overdose faced higher mortality rates than children in the general population in Michigan. Parental homicide was associated with the highest rates of mortality among children.

METHODOLOGY:

• Researchers examined mortality rates among children whose parents had died to assess the need for preventive interventions.
• They analyzed Michigan death certificates from 2009 to 2023, cross-referenced with birth certificates to identify biological parent-child pairs.
• The causes of parental death — homicide, suicide, and drug overdose or drug-related death — were identified using diagnostic codes. The researchers identified a cohort of 32,262 children aged 17 years or younger who experienced parental death from these causes.
• The study outcome was mortality among bereaved children identified via death certificates; group-specific mortality rates were calculated and compared with Michigan’s overall child mortality rate of 5.22 deaths per 10,000.

TAKEAWAY:

• Following parental homicide, children had the highest mortality rate of 106.10 deaths per 10,000, and following parental suicide, the mortality rate was 66.16 deaths per 10,000.
• Following parental drug overdose or drug-related death, children had a mortality rate of 36.97 deaths per 10,000.
• The mortality rates among children who experienced parental deaths due to homicide, suicide, and drug overdose or drug-related causes were substantially elevated compared with the overall Michigan child mortality rate, accounting for nearly 150 excess child deaths.

IN PRACTICE:

“The findings indicate that preventing parental deaths from overdoses, suicides, and homicides would be associated with lower mortality among children,” the authors wrote. “Early preventive interventions and childhood bereavement services are critical for the growing population of children experiencing parental deaths,” they added.

This study was led by Sean Esteban McCabe, PhD, of the Center for the Study of Drugs, Alcohol, Smoking and Health at the University of Michigan in Ann Arbor, Michigan. It was published online on March 23, 2026, in JAMA Network Open.

LIMITATIONS:

Paternal deaths may be underreported, leading to underestimated effects. The study did not establish causation between parental death and childhood mortality.
