The purpose of this investigation was to develop screening instruments for
the prediction of infants' growth failure. Biological and social variables
of subjects attending public clinics in Santiago, Chile, were prospectively
collected and screened as possible risk factors of being underweight/age at
the end of the first year of life using three methodologies. Methodologies
used were: simple relative risk, logistic regression, and classification
and regression trees. As judged by sensitivity and specificity properties,
the screening instrument developed by the latter methodology is much better
than the other two.
