RESUMO
Many HIV-1-seropositive women in Africa who are offered antiretroviral prophylaxis to prevent mother-to-child transmission (MTCT) of HIV do not begin interventions. Research on barriers to participation has not addressed the possible effects of women's sociocultural and economic circumstances. We examined these factors at an MTCT prevention programme in Abidjan, Cote d'Ivoire. We interviewed two groups of women after they had received HIV-positive test results and had been invited by the programme staff to return for monthly follow-up visits before beginning short-course zidovudine prophylaxis. Participants (n = 30) completed follow-up visits and prophylaxis. Non-participants (n = 27) refused or discontinued follow-up visits and did not begin zidovudine. Fewer non-participants had been born in Cote d'Ivoire (67% vs. 97%) or were Ivorian nationals (48% vs. 77%); they had lived in the country for less time (21 vs. 26 median years). They were less likely to be French-literate (37% vs. 77%), and more of them reported having had Koranic education only (18% vs. 0). They more often reported miscarriages, stillbirths, or infant deaths (69% vs. 33%), and had partners with low-ranked jobs (63% vs. 30%). Our findings suggest that the non-participants were more marginal socioculturally and economically in Ivorian society than participants. Greater attention to mitigating the effects of broader structural factors on women's participation in interventions may increase the effectiveness of MTCT prevention in Africa.
