  1. aIndependent variables in the logistic regression model included participants’ age, education, residence status, migrant status, occupation, marital status, parity, and cognition of possible adverse health effects of having an abortion, participants’ sexual partners’ age, education, occupation, income per month, and willingness to use contraception, and contraceptive use at the time of conception. However, considering the table size, here we just reported the results for these significant variables
