RESUMEN
INTRODUCTION: clandestine abortions increase maternal morbi-mortality in sub-Saharan Africa and are closely linked to restrictive legislation and low contraceptive prevalence. In Brazzaville street drugs are commonly used to induce abortion. The purpose of this study is to determine street drug prevalence and socio-demographic characteristics of these patients. METHODS: we conducted a longitudinal study of 67 patients with induced abortion complications admitted to the Talangaï Hospital from July to December 2018. (i) Socio-demographic (ii) and obstetrical (iii) characteristics as well as abortion features (procedure, Manganguiste involvement, abortion rank and cost) were collected and analyzed using EPI info 7 software. We compared the means using student's test, proportions with CHI-2, p value was set to < 0.05. RESULTS: the average age of patients was 25 years ± 6.6; 59.7% of them were attending college, 53.8% had no income-generating activity, 38.8% lived alone and in 15% of cases biological father had denied paternity. Street drugs had been used in 74.5% of cases, mean abortion cost was 3500 CFA (US$7) and 29500CFA (US$59) when it had been performed by health-care professionals. High school respondents were more likely (73.69%) to know at least contraceptive methods (p<0.05). Greater numbers of singles (p=0.000) and of those who knew a contraceptive method (p=0.003) expressed the intention to use contraception. Conclusion: combatting the use of street drugs and securing the right to safe voluntary abortion are necessary to limit complications due to clandestine abortions.
