Factors associated with the obtaining of a second-trimester induced abortion.

This study investigated the factors associated with the obtaining of a second-trimester induced abortion in women consulting the Family Planning Clinic of Le Centre Hospitalier de l'Université Laval in Quebec City, between September 6, 1988 and May 11, 1990. During the study period, 2,771 women obtained abortions at between six and 16 weeks of gestation in a multidisciplinary setting. Of 18 independent variables entered in a stepwise multiple regression analysis, ten made independent contributions to explain the variance at least at the p < 0.05 level of statistical significance. Taken together, these ten variables explained 9.4% of the total variance in gestational age: being young; having a low level of education; living far from the clinic; having other children; having a sexually transmitted disease before the abortion; not using contraception or using oral contraceptives at the time of conception, or being sterilized or having a sexual partner who has had a vasectomy; having had few sexual partners in the year preceding the abortion; not having a significant relationship with a regular sexual partner; being ambivalent about the decision to abort; and having a delay between the first consultation with the clinic and the abortion.
