[Value and value in use of "hygiene in crèches" (author's transl)]

The results of an investigation of crèches in an urban and in a rural district are discussed in regard of the possibilities of improving the material conditions and equipment in connection with their economic effects (milk kitchen, microclimate, crèches for staff training, problems of supply). The special problems of building crèches in rural areas are explained. Based on own investigative results and on economic calculations the economic benefit of crèches and the economic loss in absent morbidity of children were computed. On this background and by the help of a comparison of extreme groups, of a comparison of the rural with the urban district and of factor analysis (two forms) the attempt is made to evaluate the main causes of children's absent morbidity especially of the morbidity of the respiratory system. Conclusions with respect to the future development of building crèches are performed.
