[Study on the risk factors of induced abortion among floating women of childbearing age in 5 cities of China].

OBJECTIVE

To understand the status of abortion and risk factors among floating women of childbearing age and to provide reference for further improvement of induced abortion services in this population.

METHODS

Data on demography, working, and living conditions as well as the use of contraceptive among 4687 persons from a reproductive health survey regarding floating population in five cities in 2005, were involved, while multivariate logistic regression model was used to find out the relationship.

RESULTS

The risks of abortion among the younger than 30 age group and the 30 - 39 age groups were 2.21 times (95%CI: 1.47 - 3.34) and 2.38 times (95%CI: 1.53 - 3.70) of the 40 - 49 age group, respectively. The higher education degree these women had, the higher the risk of abortion was. The risks of abortion among groups having elementary, junior high, senior high school and above, were 2.15 times (95%CI: 1.15 - 4.03), 2.47 times (95%CI: 1.33 - 4.57) and 2.61 times (95%CI: 1.34 - 5.11) of those illiterate women. Those having working experience of 2 - 4 years, 5 years or above at the places where the survey was completed, the risks were 2.62 times (95%CI: 1.83 - 3.76) and 7.78 times (95%CI: 5.63 - 10.75) of the less than 2-year-experienced group. The abortion risk of floating women at childbearing age who were living together with their spouses was 1.49 (95%CI: 1.05 - 2.11) times of those women who were not.

CONCLUSION

The demographic and lifestyle as well as working features of floating women at childbearing age might increase their risk of abortion. Providing health education regarding these risk factors on the floating women at childbearing age could effectively reduce and prevent the risk of abortion risk among them.
