Objectives. Specify epidemioclinical and legal aspects of sexual abuse among minors and evaluate the cost of care in Dakar. Materials and methods'. This is a retrospective multicenter cross-sectional study on sexual abuse among minors over a period of four years from 1st January 2006 to 31st December 2009. Four maternities were targeted: the Social Hygiene Institute of Medina, health center Roi-Baudouin Guediawaye, the Pikine hospital and health center Youssou-Mbargane-Diop of Rufisque. Results. During the study period, 252 child victims of sexual abuse were supported at four health facilities on a total of 272 sexual abuses of all ages, a frequency of 92.64%. The epidemiological profile of our patients was a child of 11 years old on average, female (100%) and living in the suburbs of Dakar (68.1%). Children were often abused during working hours (31.7%), outside the family environment and often by someone known to the victim (72.6%). Genito-genital contact was the most common mode of sexual contact (80.9%) with vaginal penetration in 61% of cases. Almost all of the victims (92.1%) came to consult, accompanied by their parents, between the 1st and 4th day after the sexual abuse (70%). The examination usually revealed a hymenal trauma (59.9%) of which nearly half (49%) consisted of old lesions. 56.9% of victims had a post-traumatic stress disorder and 31.1%, mutism. We recorded six (6) pregnancies, 2% of our sample. A case of HIV infection was recorded on a sample taken 72 hours after sexual abuse. Control of three months HIV serology was requested in 7.1% of cases and only 20% of children had received antiretroviral prophylaxis. Antibiotic prophylaxis had been performed in 13.7% of cases using doxycycline as drug of choice (75%). Only 29% of our patients had received emergency contraception progestin and psychological care concerned only 22% of children. On the legal aspects, 46% of our patients had filed a complaint. Prosecutions were 38%, 45% of which were convicted and 21% were acquitted. The rate of out-of-court settlement was 35% and the time limit for settlement by the justice was on average 6 months with extremes of one month and 24 months. The average cost of care was estimated at 17,010 CFA francs (26 euros) taking into account the consumables used for clinical examination (sterile gloves, catheter, syringe), analysis and prescription drugs. Conclusion. The sexual abuse of minors is a disturbing reality that raises rightly universal reprobation. In Senegal, this mainly affects children and its magnitude is increasing over the years. Improved support for victims necessarily involves raising public awareness through the media and the development of specialized structures in the management of sexual abuse.
