Contraceptive use, protected sexual intercourse and incidence of pregnancies among African HIV-infected women. DITRAME ANRS 049 Project, Abidjan 1995–2000

Abstract

The aim of this paper is to describe the adherence of African HIV+ women to the counselling provided after announcement of the result of the HIV test during pregnancy, focusing on early weaning to reduce post-natal transmission, protected sexual intercourse to avoid sexual transmission, and contraceptive use to avoid unexpected pregnancies. In 1999-2000, a questionnaire on sexual and reproductive behaviours was administered to 149 HIV+ women followed in post-partum, informed and counselled in the ANRS 049 DITRAME project in Abidjan. Côte d'Ivoire. Duration of breastfeeding, post-partum amenorrhea and abstinence, contraceptive use and condom use were measured. Incidence of pregnancies during the first 24 months post partum was estimated and modelled by a Cox regression model. Average duration of breastfeeding was 7.9 months, average duration of post partum abstinence was 12.0 months, and 39% of women used contraceptives at the time of the survey. Frequency of condom use was 13%. Incidence of pregnancies was 16.5 per 100 women-years at risk. Half of these pregnancies were not desired and a third were terminated by induced abortion. The significant determinants of the pregnancy occurrence were the death of the previous child, the cessation of breastfeeding, the cessation of the post partum abstinence, and higher education. In conclusion, if counselling on early weaning can be followed by the HIV+ women, it is not easily the case for condom and contraceptive use. Hence, pregnancy incidence in the post-partum follow-up was high. The main strategy of these HIV+ women to avoid unexpected pregnancies as well as sexual transmission of HIV seems to be an increase of the duration of post-partum abstinence. The most educated women who cannot easily adopt this strategy are particularly exposed to unwanted pregnancies.

“…Similar findings were reported among HIV positive women receiving prevention of mother to child transmis- sion (PMTCT) services in Rwanda and Cote d'Ivoire where women in a union were more likely to report a modern method (Batya et al, 2009;Desgrees et al, 2002).…”

Reproductive Choice for Women and Men Living with HIV: Contraception, Abortion and Fertility

“…In a study carried out in Cô te d'Ivoire, a third of pregnant HIV positive women terminated a pregnancy in spite of legal restrictions. 83 More research among HIV positive women in developing countries is needed on the complications of unsafe abortion and whether increased access to antiretrovirals is altering decisions about pregnancy termination.…”

“…Three randomized controlled trials carried out in sub-Saharan Africa to assess the impact of male circumcision on HIV acquisition among heterosexual men (44)(45)(46) showed a strong protective effect, with an approximately 60% reduction in the risk of acquiring HIV. Additional research has demonstrated that the duration of the benefi cial impact of male circumcision on HIV transmission is also longer than indicated by earlier evidence (47).…”
