Nutrition intervention: an evaluation of six studies.

Six nutrition intervention studies were evaluated in the context of a predetermined methodology covering several categories of evaluative criteria. After a presentation of reasons for including each study, a summary is presented of the results of each study in light of the present investigators' evaluation and secondary analyses. Nutrition intervention programs can have a positive effect on health indices of infants and children, but much can be done in future nutrition projects to improve project design and thereby assist and facilitate more meaningful evaluations of nutrition intervention. To this end, a set of points for consideration by those designing nutrition intervention projects is provided.
