[Correlations between pre, peri, and postnatal risk factors and the psychomotor development during the 1st half year of life].
Data from 1288 illustrated questionnaires were analysed with regard to the correlation of pre-, peri- and postnatal complications and infant psychomotor development. The information on the infants' case history was obtained through the parents retrospectively. Data on psychomotor development were gained prospectively by means of continuous parental observation. Statistical evaluation showed that correlations among many risk factors in our sample and developmental items decrease already during the first six months of life. That is to say, depending on the length of time subsequent to their pre- and perinatal effects many obstetric complications lose their significance for a given state of psychomotor development as well as for prognosis. Furthermore, one should consider that even prediction through recent and current risk factors may often only be of short-term value.
