• Longitudinal lipid and obesity-related trajectories in youth show persistent lipid pattern changes shaped by adiposity and growth, with Bogalusa and related cohorts illustrating how obesity modulates lipids and lipoproteins [1], [6], [7], [19].

• Physical fitness and activity emerge as primary determinants of multiple cardiovascular risk factors in adolescence, including lipid profiles, blood pressure, and obesity, across several cohort studies [3], [8], [9], [20], [11].

• School- and community-based risk-factor interventions demonstrate the feasibility and impact of structured programs on knowledge and behavioral and biochemical risk factors in youth [4], [12], [13], [19].

• Early-life influences on later cardiovascular risk include intrauterine growth and birth weight effects on adult blood pressure and mortality trajectories, indicating developmental origins of disease [18], [16].

• Screening and risk-factor identification approaches in pediatric populations—family history and biochemical data—provide foundations for identifying hyperlipidemia and future CHD risk in children [17], [14].
