coronary arteries and abdominal aortas to develop the PDAY Risk Score (RS) to predict the likelihood of young people having advanced preclinical atherosclerosis lesions.
The RDAY RS weighted risk factors differently than the FRS due to differences in how a risk factor may affect CHD, but sufficiently determined risk for future CHD in young persons.
Childhood CVD risk factor clustering (simply a higher number of distinct risk factors per individual) is noted to be more predictive of CVD when an adult. Pourebrahim et al. (2006) found that CVD risk factors are more prevalent, and more clustered in high-risk families. Shah, Dolan, Gao, Kimball, and Urbina (2011) evaluated whether clustering CVD risk could detect early atherosclerotic lesions in youth, and compared risk clustering to the PDAY RS for predicting early CVD. Results found that the presence of two or more risk factors per individual was reliably associated with vascular changes in adolescents but, a key point for the current study, could not detect when (or age) these changes occurred in relation to when children began accruing CVD risk factors.
