Lipid Profiles in First-Grade Students Reveal Early Cardiovascular Risks in Zabrze, Poland
Overview
A screening of 661 first-grade students in Zabrze, Poland, found that 14.8% had total cholesterol (TC) levels above 190 mg/dL, and over half had TC above 170 mg/dL, indicating elevated cardiovascular risk. Additionally, 31% of children were overweight or obese, highlighting the early presence of modifiable risk factors in this population.
Background
Cardiovascular diseases are the leading cause of death worldwide, with premature exposure to risk factors contributing significantly. In Poland, hypercholesterolaemia affects approximately 20 million people. Early diagnosis and intervention in children can reduce long-term morbidity and mortality. Screening programs in children, such as the one conducted in Zabrze, aim to identify lipid abnormalities and other risk factors early to enable timely prevention.

Key Findings
14.8% of first-grade children had total cholesterol levels exceeding 190 mg/dL, indicating elevated cardiovascular risk.
Over half (51.6%) had total cholesterol levels above 170 mg/dL, a threshold suggestive of increased risk.
Approximately 31% of children were overweight or obese, with no significant sex differences.
Random glycaemia above 100 mg/dL was common (70.7%), though no child had levels indicating diabetes.
No children exhibited blood pressure readings at or above the 90th percentile for age, sex, and height.
Follow-up attendance for children with elevated cholesterol was low (17.3%), limiting further evaluation and intervention.
Clinical Implications
Early screening for lipid abnormalities and overweight in children is feasible and reveals a substantial burden of cardiovascular risk factors even at a young age. However, voluntary participation and low follow-up rates highlight the need for enhanced educational efforts and structured programs to improve adherence and ensure timely intervention. Incorporating such screening into routine pediatric care could facilitate early prevention strategies.
Conclusion
The study demonstrates a high prevalence of elevated cholesterol and overweight among first-grade children in Zabrze, underscoring the importance of early cardiovascular risk assessment. Effective implementation of screening programs and follow-up strategies is essential to reduce future cardiovascular morbidity.
