Unwanted pregnancy occured equally in respondents with good and poor knowledge of reproductive health, respectively 3,7%. Chi-square analysis showed that the factors that were significantly associated with unwanted pregnancy were history of parity (p = 0,0001; OR = 18,97; 95%CI = 9,33-38,58), history of contraceptive use (p = 0,0001; OR = 5,29; 95%CI = 2,36-11,86), and breastfeeding behavior (p= 0,005; OR= 0,23; 95%CI = 0,09-0,63). The factors that were not significantly related were employment status (p = 0,804; OR = 0,904; 95%CI = 0,56-1,46 ) and knowledge of reproductive health (p = 1,0; OR = 0,012; 95%CI = 0,53-1,94).
