[Indicators for population and individual risk in assessing the effect of environmental factors on the health of children].
Populational studies define a risk for abnormalities forming in children residing in varying polluted areas and compare it with the risk due to other health-forming factors. To define an individual risk, the authors have developed scales rating the likelihood of abnormalities that can occur in each child in relation to the biomedical or social risk factors in children, to their residence in poor environmental areas, to the child's age and sex.
