title: [Structural features of obstetric abnormalities of pregnant, parturient and puerperal women during perinatal period, evaluated from a viewpoint of main component (author's transl)].
abstract: With an aim to analyze abnormalities of women with high risk pregnancy, labor and puerperium during perinatal period, main component analysis was carried out for 860 perinatal women, using each of six groups (large items) of 29 kinds of their abnormalities (small items) as variables and the following results were obtained. 1) Three main components were extracted and their cumulative communarity was 61.9 per cent. 2) Each of the main component was evaluated using the large items themselves and correlation between the large items and the small ones. The first main component was considered to be related to disturbance of fetal passage through the birth canal, the second to utero-placental dysfunction and obstetric surgery due to other indications than the disturbance of fetal passage through the birth canal, the third to the complications accidental to pregnancy. 3) Main component scores of the three main components were stratified by physical conditions of the newborn infants by the analyzed perinatal women and the correlation between the both were evaluated. Explanation of the first main component was found to be reasonable from its correlation with birth weight, developmental status, hyperbilirubinemia, Apgar score massive aspiration syndrome of the newborn infants.
