Sedentary childhood tied to heart damage in young adulthood

New findings from ESC Congress 2023 reveal that inactivity during childhood can lead to heart damage in young adulthood – this is strongly linked to sedentary time,

These findings are staggering as this is found in even in those with average weight and blood pressure.

Dr Andrew Agbaje, from the University of Eastern Finland, highlights the impact of excessive screen time on youth. He says that hours spent in front of screens contribute to a heavier heart, increasing the risk of heart attack and stroke in the future.

Heart damage in young adulthood linked to being sedentary/inactive

For the first time, researchers investigated the connection between smartwatch-monitored sedentary behaviour in young individuals and cardiac issues.

The study, part of the long-term Children of the 90s project, examined data from birth onward to uncover patterns.

Participants wore smartwatches with activity trackers at ages 11, 15, and 24. Heart health was assessed using echocardiography at ages 17 and 24. The study scrutinised the relationship between sedentary behaviour (ages 11 to 24) and heart measurements (ages 17 to 24), accounting for various influencing factors.

Importance of combatting sedentary habits

The study enrolled 766 children (55% girls and 45% boys). Sedentary time increased significantly over the ages: from 362 minutes at age 11 to 531 minutes at age 24.

Every additional minute of inactivity between ages 11 and 24 was correlated with a 0.004 g/m2.7 rise in left ventricular mass between ages 17 and 24.

This study underscores the critical importance of combatting sedentary habits in youth. The concerning link between childhood inactivity and heart damage in young adulthood demands attention.

Dr. Agbaje urges parents to encourage physical activity and limit screen time, echoing Martin Luther King Jr.’s wisdom: “Keep moving, no matter how you do it.”

The need to fight immobility

In a digital age that often encourages immobility, these findings serve as a wake-up call. The evidence of heart damage in young adulthood stemming from childhood inactivity underscores the long-term consequences of sedentary habits.

The study’s revelations emphasise the need for a multifaceted approach involving individuals and society. Empowering children and teenagers to prioritise movement and outdoor activities can pave the way for healthier futures.
