Parental Divorce in Childhood Linked to Higher Stroke Risk in Later Life, Study Finds
A groundbreaking study published in the journal PLOS One has uncovered a startling connection between parental divorce during childhood and a considerably higher risk of stroke in older adults. Researchers from the University of Toronto, Tyndale University, and the University of Texas at Arlington analyzed data from 13,205 Americans aged 65 and older, revealing that those who experienced parental divorce face a 61% higher risk of stroke compared to individuals from intact families.
The study, which utilized data collected by the U.S. Centers for Disease Control and Prevention in 2022, found that 13.9% of participants had experienced their parents’ divorce before the age of 18. Most of these divorces occurred during the 1960s and 1970s, a time when divorce was less common. The researchers aimed to explore the long-term health consequences of childhood family dynamics, especially focusing on how early life stressors might influence adult health outcomes.
“We found that even when individuals had not suffered physical and sexual abuse in childhood and had at least one adult who made them feel safe in their childhood home, they were still more likely to suffer a stroke if their parents had divorced,” said philip Baiden, one of the researchers involved in the study, according to The Economic times.
The elevated stroke risk persisted even after accounting for known risk factors such as smoking, physical inactivity, lower income and education, diabetes, depression, and low social support. “Our study indicates that even after accounting for most known risk factors associated with stroke, those whose parents had divorced were still 61% more likely to suffer a stroke,” added Mary Kate Schilke, a professor in the Department of Psychology at Tyndale University.
The Biological Connection
Esme Fuller-Thomson, the lead author of the study and a professor at the University of Toronto, explained that the exact reason for the correlation remains unclear. However, the researchers hypothesize that the mechanism could be biological.”From a biological outlook, parental divorce in childhood could lead to persistently high levels of stress hormones. Experiencing this event as a child could have lasting effects on the developing brain and the child’s ability to respond to stress,” Fuller-Thomson noted.
Interestingly, the study found that other forms of childhood adversity, such as emotional abuse, neglect, mental illness in the home, substance abuse, or exposure to parental domestic violence, were not associated with stroke. This specificity makes the divorce-stroke connection even more intriguing, suggesting that childhood family experiences may have a unique impact on long-term cardiovascular health.
Limitations and Future Research
The researchers acknowledged several limitations in their study. Factors such as blood pressure, cholesterol, contraceptive use, age at parents’ divorce, and types of strokes were not available in the data. Additionally, they clarified that their conclusions may not be generalizable to younger generations, who have experienced higher rates of parental divorce.
“due to changes in societal norms, it is uncertain whether Generation X or Millennials will experience the same connection between parental divorce and stroke as the Baby Boom and Silent Generations in our study,” Fuller-Thomson said.This study replicates findings from a similar study conducted nearly a decade ago, which also found strong links between parental divorce and increased stroke risk. The consistent results underscore the profound impact of childhood family experiences on long-term health.
Key Findings at a Glance
| Aspect | Details |
|———————————|—————————————————————————–|
| Study Participants | 13,205 Americans aged 65 and older |
| Parental Divorce Rate | 13.9% experienced parental divorce before age 18 |
| Increased Stroke Risk | 61% higher risk compared to those from intact families |
| Key Hypothesized Mechanism | Persistent high levels of stress hormones due to childhood trauma |
| Other Adversities Examined | Emotional abuse, neglect, mental illness, substance abuse, domestic violence (no significant link to stroke) |
What This Means for Families and Healthcare Providers
The findings highlight the importance of addressing childhood stressors and their potential long-term health impacts.While the study dose not establish causality,it opens the door for further research into how early life experiences shape health outcomes in later years.
For families navigating divorce, these findings underscore the need for supportive interventions to mitigate the emotional and psychological effects on children. Healthcare providers, too, may consider incorporating family history into their assessments of stroke risk, particularly for older adults.
As research continues to uncover the intricate links between childhood experiences and adult health, this study serves as a reminder of the lasting impact of family dynamics on our well-being.
