RÉSUMÉ
In Côte d'Ivoire, contraceptive prevalence is low (21%). The search for determinants of contraceptive use could make it possible to redirect existing strategies. The objective is to identify the determinants of the use of contraception among women in Abidjan. A cross-sectional survey was conducted from May to June 2018 in the Dallas neighborhood of Adjamé municipal (Abidjan). Women of reproductive age (15 to 49 years old) were selected there. Sociodemographic, gyneco-obstetrical characteristics, educational level, attitudes and practices of women on contraception were collected. Univariate and multivariate analyzes were performed. A total of 301 women aged 29.34±8.98 years were selected. The proportion of women using modern contraception was 27.24%. In univariate analysis, the factors associated with use were: level of education (p=0.005), unwanted pregnancies (p=0.017), abortions (p<0.001), consultation of the gynecologist (p=0.003) or a family planning service (p=0.001). Hearing about contraception (p=0.043), knowing (p<0.001) and talking about it with their partner (p=0.027) was significantly associated with its use. In the multivariate analyses, the women who consulted a gynecologist and those who knew the contraceptive methods used them respectively 2 times more (OR= 2.16 [1.14-4.15], p=0.019) and 22 times more (OR= 22.38 [8.42-78.56], p<0.001). Women with primary school education used them significantly less (OR=0.15 [0.05-0.41], p<0.001). Awareness, the gynecologist's consultation, and the level of education were the main determinants of contraceptive use. Also, it is necessary to adapt awareness messages to the characteristics of women.
