Positive experiences can protect children’s heart health

A new study finds that childhood adversity can harm a child’s heart health, but positive experiences provide a buffer.

The research, led by the Murdoch Children’s Research Institute and published in the International Journal of Cardiologyfound that negative experiences had a negative impact on children’s cardiovascular health, while positive experiences had a beneficial effect and could 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 found that childhood adversities experienced from birth to age 11, such as domestic violence and parental mental health problems, could lead to poor cardiovascular health later in childhood. Conversely, positive experiences such as warm parenting and living in a safe environment were linked to better heart health.

Positive experiences may also explain why some children thrive in difficult times, acting as a buffer against the potential negative effects on cardiovascular health.

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

He said public health programs focused on prevention and using evidence-based approaches were 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, building 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 of life, we can create a healthier future for all Australian children.”
