There is a steep socio-economic gradient in the probability of having an unsafe abortion: poorer women are more likely to have an unsafe abortion than richer women (OR = 2.48, 95% CI = 1.09–5.63); women with 6–9 years of education (OR = 0.30, 95% CI = 0.11–0.81) and with more than 13 years of education are less likely to have an unsafe abortion (OR = 0.065, 95% CI = 0.01–0.43), and women with indigenous origin are more likely to have an unsafe abortion (OR = 5.44, 95% CI = 1.91–15.51).
Thus, the probability for poor women with less than 5 years of education and indigenous origin is nine times higher compared with rich, educated and not indigenous women.
Respondents were asked: (1) if the abortion was a mistimed or unwanted birth, (2) whether the abortion was spontaneous, induced by medication, induced by injection or other procedure, (3) the type of provider who performed the abortion (doctor, nurse, auxiliary worker, traditional birth attendant, the respondent herself or other) and (4) the facility where the abortion was performed (social security, public or private clinic or hospital, traditional birth attendant’s residence or in the respondent’s home).
The survey did not collect information on the reason for the termination of the pregnancy or on the use of contraception methods during the cycle of conception.
ENADID is an interviewer-administered household survey which is representative at state level.
It is designed to collect detailed information on women aged between 15 and 55 years on social and demographic characteristics, child health and a range of reproductive health issues, including family planning, fertility, contraceptive knowledge and use.The total sample is 38 661 women between 15 and 55 years old.We limited the analysis to women who reported having an abortion during the 5 years preceding the survey to avoid recall bias problems with reporting on events that happened in the distant past.For each pregnancy, women were asked to provide information on whether it ended in an abortion (defined in this survey as pregnancy termination up to 5 months of gestation), the date of abortion and the gestational age at the time of the abortion.Women who reported having had an abortion were asked more detailed questions on the most recent abortion.In Mexico, studies have been undertaken to improve estimates of induced abortion but the determinants of unsafe abortion have not been explored.Methods We analysed data from the 2006 Mexican National Demographic Survey.Monitoring trends in unsafe abortion practices as well as sharing countries’ experience on policies and interventions that have been successful in reducing unsafe abortions is crucial, as the half-way point towards achieving the MDGs has been reached.It is estimated that 22% of all pregnancies worldwide end in an induced abortion—approximately 50 million each year around the year 2000 (Guttmacher Institute 1999).Information was collected for the most recent abortion reported for each respondent on the type of provider, facility and technique, and whether the pregnancy was wanted or not.Information was also collected on the socio-economic and demographic characteristics of the respondent.
