Light activity Plays Key Role in Reversing Childhood Cholesterol Risks
updated June 16, 2025
A new study reveals that light physical activity, such as walking or chores, is more effective than moderate-to-vigorous exercise in combating high cholesterol linked to sedentary behavior in children. The research, a collaboration between the University of Exeter, the University of Eastern Finland, and the University of Bristol, was published in The Journal of Clinical Endocrinology & Metabolism.
Researchers analyzed data from the University of Bristol’s “Children of the 90s” study, following 792 participants from age 11 to 24.The findings indicated that prolonged sedentary time during childhood could increase cholesterol levels by as much as 67% by the time individuals reach their mid-20s. Elevated cholesterol during these formative years is associated with increased risk of premature death and heart problems later in life.
While the World Health Organization (WHO) recommends 60 minutes of moderate-to-vigorous physical activity daily for children, this study suggests that incorporating light physical activity may be a more impactful strategy for promoting heart health. Light physical activity was found to be up to five times more effective at lowering inflammation and promoting healthy hearts in young people.
Dr. Andrew Agbaje, from the University of Exeter, led the study.
“These findings emphasize the incredible health importance of light physical activity and shows it could be the key to preventing elevated cholesterol and dyslipidaemia from early life,” Agbaje said.
The study tracked participants’ sedentary time, light physical activity, and moderate-to-vigorous physical activity at ages 11, 15, and 24. Cholesterol levels were measured at ages 15, 17, and 24, alongside other health indicators like body fat, muscle mass, and blood glucose.
Over the 13-year study, sedentary time increased from six to nine hours daily, while light physical activity decreased from six to three hours.Moderate-to-vigorous physical activity remained relatively stable at around 50 minutes per day. An average of four-and-a-half hours of light physical activity was found to decrease total cholesterol, even though body fat could reduce this effect. Moderate-to-vigorous activity also showed a slight reduction in cholesterol, but its impact was significantly diminished by increased body fat.
What’s next
researchers suggest that future guidelines shoudl emphasize the importance of incorporating more light physical activity into children’s daily routines to combat the negative effects of sedentary lifestyles on cholesterol levels and overall heart health.
