Abstract

Highlights What are the main findings? The physician-led counseling intervention showed a favorable but non-significant trend toward lower total cholesterol (TC) levels in children with elevated cholesterol levels and a negative family history of familial hypercholesterolemia (FH). The intervention was associated with improved adherence to the Mediterranean diet and favorable exploratory changes in selected physical activity and sedentary behavior outcomes. What are the implications of the main findings? Physician-led counseling within school healthcare settings may help support healthier lifestyle awareness and selected health-related behaviors among children and families. Further studies with larger samples, longer follow-up periods, and comprehensive lipid assessment are needed to confirm the effectiveness of this approach, including in children with elevated cholesterol levels and a positive family history of FH. Abstract Background: This randomized controlled trial aimed to evaluate the effects of a school physician-led counseling intervention on total cholesterol (TC) levels, adherence to the Mediterranean diet, physical activity, and sedentary behavior in children aged 6–7 years with elevated cholesterol levels in a Mediterranean setting. Methods: A one-year randomized controlled study was conducted among children aged 6–7 years with elevated TC levels, excluding those with familial hypercholesterolemia (FH). Participants were randomly assigned to either a control…
