title: [Pregnancy in women 40 years of age and over: analysis of variables in the mothers and newborn infants].
abstract: Although pregnancy in women who are forty years old or more is considered a high risk pregnancy, it has occurred more frequently in recent years. This paper reports an analysis of 205 cases of patients over forty years of age seen at the Obstetrics Department of the São Paulo School of Medicine at the São Paulo Hospital. A control group of 1,153 pregnant women ages ranging from 20 to 29--such age range being considered the proper age for reproduction--was formed for the purpose of comparison. Data were stored in computer and lists of many variables were settled to provide a statistical overview through non-parametric testing based on the nature of the variables. 5% was the level of significance set to reject a null hypothesis. The results permit authors to conclude that pregnant women who are forty years old or over present inadequate biological characteristics for a proper obstetric development, based on the advanced age and on the association of many other adverse factors.
