The mean score of attitude towards childbearing was 70.46 (SD=14.87). The findings showed that there were no statistically significant differences between the mean attitude score towards childbearing and age (p=0.788), housing status (p=0.505) and income (p=0.210). However, there were significant differences between the mean attitude score towards childbearing and educational level of the women (p>0.001) and their husbands (p0.001) and their husbands (p=0.024).
