Abstract: Rwanda’s high population growth constitutes a major challenge to the economic development. In 2010 Rwanda’s population growth rate was of 2.6%. Over time, the use of Long Acting Contraceptive Methods (LACM) has not been opted for as short acting methods. In the study conducted in Kicukiro District to assess barriers to the use of LACM, the main objective was to identify the barriers to the use of LACM. Specifically, to measure prevailing rate of LACM use, to measure the association between socio-demographic characteristics and the use of LACM, to identify current knowledge and attitudes regarding LACM. To meet all those objectives, a cross sectional study was conducted. The study participants were 96 women and proportionate sampling method was used. About 95.8% of participants had general knowledge about LACM. The study showed that LACM use increases significantly with the level of education (OR: 6.500; p=0.012), the number of living children (four and above: OR: 14.25 p<0.001), the family size (four and above: OR: 8.591 p<0.046), the joint discussion with partner on the number of children to bear (OR: 5.053; P=0.048) and partner agreement to the use of LACM (OR: 3.659; P=0.038). According to the study, the use of LACM decreases significantly with desire of having another child (OR: 0.389; P=0.040) and negative attitude toward LACM (OR: 0.166, P=0.014). Campaigns against negative attitudes toward LACM should be strengthened.
