Positive experiences can protect children’s heart health

A new study shows that difficult experiences in childhood can harm children’s heart health, but positive experiences provide a buffer.

The study, led by the Murdoch Children’s Research Institute and International Journal of Cardiologyfound that negative experiences have a negative impact on children’s cardiovascular health, but positive experiences have a beneficial effect and can prevent some of the harm caused by adversity.

The study used data from the Longitudinal Study of Australian Children (LSAC), which followed 5,107 babies from birth to 12 years of age.

It has been found that childhood adversities between birth and age 11, such as domestic violence and parental mental illness, can lead to poor cardiovascular health in later childhood. Conversely, positive experiences such as loving parenting and living in a safe environment were associated with better heart health.

Positive experiences may also explain why some children thrive despite adverse circumstances, as they buffer some of the potential negative effects on cardiovascular health.

Dr Jun Guo of MCRI said the findings highlighted the importance of early life experiences for children’s cardiovascular health, particularly the protective role of positive experiences.

He said public health programs that focus on prevention and use evidence-based approaches are needed to support all children and families. Cardiovascular disease is the leading cause of death worldwide, accounting for about a third of all deaths.

“Promoting positive childhood experiences, such as building healthy and safe communities, maintaining strong family ties, and increasing school and community involvement, are critical to preventing future cardiovascular disease,” said Dr. Guo.

“This research shows that by investing in the early years, we can create a healthier future for all Australian children.”
