Cardiovascular risk screening in school children predicts risk in parents☆

Abstract 

Background

Since children have frequent contact with the health care system, while their young parents very often do not, screening children routinely might represent an important opportunity to target the young parents. We examined whether cardiovascular risk factors in children predicted the risk of their parents.

Methods

Five silent (hypertension, high triglycerides, high LDL-, high non-HDL-, and low HDL-cholesterol) and two clinical apparent (general and central adiposity) risk factors were compared in 2720 child–parent pairs from a well-defined sample of German elementary school children and parents.

Results

All clinical apparent and silent risk factors were significantly correlated between children and their parents, and most pronounced were those for three silent risk factors: HDL cholesterol, LDL cholesterol, and non-HDL cholesterol (correlation coefficient r=0.26–0.28). In multivariate models, adjusting for age and gender, child general and abdominal adiposity conferred a significant 2.9-fold and a 2.6-fold enhanced odds among parents of carrying the same risk factors. Similarly, abnormal LDL, HDL, or non-HDL among children conferred a significant 3.0-fold, 2.0-fold, or 2.9-fold increased odds among parents. The odds of parents appeared stronger if the child had the same sex only for clinical apparent risk factors, and most pronounced for general adiposity.

Conclusions

Cardiovascular risk screening in children may serve as a case finding strategy for early prevention in high risk families. The inclusion of silent risk factors in a screening program of school children may be warranted for the high prevalence among children and enhanced case-finding potential among parents.
