title: [An analysis of the factors influencing the use of IUD].
abstract: An introduction of the method of the theory of quantification II is given, and it is applied to evaluation of the factors influencing the use of IUD. From the epidemiological data obtained in Jilin City, eight more important factors were screened. These factors are age of first parturition, age of first menses, condition of putting the IUD in, number of early stage induced abortion, number of gestation, labour posture, labour intensity and number of parturition. By comparing the results of analysis between the theory of the quantification and the Bayes discrimination analysis, it is shown that the former method is more objective and therefore the results are more reliable.
