Adolescence: a critical period for long-term tracking of risk for coronary heart disease?

Tracking of dietary and physical activity patterns throughout adolescence into adulthood is low, which indicates that risk patterns for coronary heart disease are not maintained. Biological risk factors for heart disease, particularly obesity and clusters of nutritionally modifiable risk factors (e.g. the metabolic syndrome), display somewhat higher tracking correlations. Tracking gives little guidance as to how to use this information for screening purposes. For behavioral and biological risk factors predictive values and sensitivities and specificities are generally low, suggesting that population-based approaches are likely to be more effective than targeting only the high-risk subset for reducing the risk of coronary heart disease.
