The majority was 25 to 29 years old 32.3%, multipares 35.4%, monogamous 66.8%, wishing 5 children or more in 43.8% and Catholic religion 33.2%. The determinants of non-use are: the desire to have other children ORa = 11.6⦋2.3-40.8⦌, the desire to have ≥5 children ORa = 7.2 ⦋2.2 - 23.8⦌, lack of employment or profitable activity ORa = 3.7 ⦋1.2 - 12.0⦌, lack of education and ORa = 12.9 ⦋2.7 - 63.5⦌, the lack of dialogue with partner ORa = 9,6 ⦋2,2 - 42,5⦌, the disapproval by the spouse ORa = 9,7⦋2,9 - 32,8⦌, the standard of living low ORa = 27 , 1 ⦋4.5 - 162⦌ and average ORa = 9; 3 ⦋2.8 - 39.9⦌.
