A randomized controlled trial to promote long-term contraceptive use among HIV-serodiscordant and concordant positive couples in Zambia

Behavioral interventions for improving contraceptive use among women living with HIV

BACKGROUND

Contraception services can help meet the family planning goals of women living with HIV as well as prevent mother-to-child transmission. Due to the increased availability of antiretroviral therapy, survival has improved for people living with HIV, and more HIV-positive women may desire to have a child or another child. This review examines behavioral interventions to improve contraceptive use, for family planning, among women who are HIV-positive.

OBJECTIVES

We systematically reviewed studies that examined behavioral interventions for HIV-positive women that were intended to inform contraceptive choice, encourage contraceptive use, or promote adherence to a contraceptive regimen.

SEARCH METHODS

Through October 2012, we searched MEDLINE, CENTRAL, POPLINE, EMBASE, CINAHL, PsycINFO, ClinicalTrials.gov and ICTRP. For other relevant papers, we examined reference lists and unpublished project reports, and contacted investigators in the field.

SELECTION CRITERIA

Studies evaluated a behavioral intervention for improving contraceptive use for contraception. The comparison could be another behavioral intervention, usual care, or no intervention. We also considered studies that compared HIV-positive women versus HIV-negative women. We included nonrandomized (observational) studies as well as randomized trials.Primary outcomes were pregnancy and contraception use, e.g., uptake of a new method, improved use or continuation of current method. Secondary outcomes were knowledge of contraceptive effectiveness and attitude about contraception in general or about a specific contraceptive method.

DATA COLLECTION AND ANALYSIS

Two authors independently extracted the data. One author entered the data into RevMan and a second verified accuracy. We examined the quality of evidence using the Newcastle-Ottawa Quality Assessment Scale.Given the need to control for confounding factors in observational studies, we used adjusted estimates from the models when available. Where we did not have adjusted analyses, we calculated the odds ratio (OR) with 95% confidence interval (CI). Due to varied study designs, we did not conduct meta-analysis.

MAIN RESULTS

The seven studies meeting our inclusion criteria had a total of 8882 women. All were conducted in Africa. Three studies compared a special intervention versus standard services. In one, the special intervention site showed greater use of non-condom contraceptives per visit (OR 6.40; 95% CI 5.37 to 7.62) and reported a lower pregnancy incidence. In another study, use of modern contraceptives was more likely for women at sites with enhanced versus basic integrated services (OR 2.48; 95% CI 1.31 to 4.72), but the groups did not differ significantly in change from baseline. In the third study, new use of modern contraceptives, excluding condoms, was less likely for women with integrated services versus those with routine care (OR 0.56; 95% CI 0.42 to 0.75), but new use of condoms was more likely (OR 1.73; 95% CI 1.52 to 1.98).Four older studies compared HIV-positive women versus HIV-negative women. None showed any significant difference between the HIV-status groups in use of modern contraceptives. Two did not provide an intervention for the HIV-negative women. In the larger of the two studies, HIV-positive women were less likely to become pregnant (OR 0.55; 95% CI 0.43 to 0.69). HIV-positive women were more likely to discontinue their hormonal contraceptive (OR 2.52; 95% CI 1.53 to 4.14) but more likely to use condoms (OR 2.82; 95% CI 2.18 to 3.65) and spermicide (OR 2.36; 95% CI 1.69 to 3.30). Two studies provided the intervention to both HIV-status groups. One included many of the women from the study just mentioned, and also showed fewer pregnancies for HIV-positive women (OR 0.39; 95% CI 0.23 to 0.68). In the other study, the HIV-status groups were not significantly different for pregnancy or consistent condom use.

AUTHORS' CONCLUSIONS

Comparative research on contraceptive counseling for HIV-positive women has been limited. We found little innovation in the behavioral interventions. Our ability to make statements about overall results is hampered by varied study designs, interventions, and outcome assessments. The quality of evidence was moderate. Since some of these studies were conducted, improvements in HIV treatment have influenced the fertility intentions of HIV-positive people.The family planning field needs better ways to help women choose an appropriate contraceptive and continue using that chosen method. Women with HIV may have special concerns regarding family planning. Research could focus on assessing the woman's needs and training providers to address those issues rather than delivering standardized information.

Quality of relationship and sexual risk behaviors among HIV couples in Lusaka, Zambia

Relationship quality and partner dynamics provide important insights into understanding sexual behavior within HIV sero-positive and sero-discordant couples. Individuals in long-term partnerships may be vulnerable to HIV/sexually transmitted infections (STI) within their relationships due to misperceptions of their partners risk behaviors and potential concurrent (e.g., extramarital, nonprimary) sexual partnerships. This study sought to examine relationship quality among HIV sero-positive and sero-discordant couples in Zambia, and its association with safer sex behavior. This study utilized data drawn from an ongoing translational study, The Partnership II Project - a couples-based sexual risk reduction intervention in Lusaka, Zambia. Couples (n=240) were assessed on demographics, relationship quality, and sexual risk behavior. Overall, couples perceiving their relationships more positively engaged in less risky sexual behavior (i.e., more condom use (b=0.011, t=3.14, p=0.002) and fewer partners (χ(2)=11.4, p=0.003). Within the dyad, condom use was "actor driven," indicating that the association between relationship quality and condom use did not depend on the partner's evaluation of the relationship. Safer sex behavior was positively influenced by communication about condoms. Results support the paradigm shift from prevention strategies with HIV-positive and at-risk individuals to concentrated efforts addressing male-female dyads, and suggest that interventions to address the role of couples' relationship quality, a modifiable target for decreasing sexual risk behavior, are needed.

Meeting the Contraceptive Needs of Key Populations Affected by HIV in Asia: An Unfinished Agenda

Like all women, women living with and at risk of acquiring HIV have the right to determine the number and timing of their pregnancies and to safely achieve their reproductive intentions. Yet, many women in Asia affected by HIV lack access to family planning services and experience disproportionately high rates of unintended pregnancy and abortion. Programs that have succeeded in promoting condom use and providing HIV prevention and treatment services in this region have largely missed the opportunity to address the contraceptive needs of the key populations they serve. The importance of better linkages between family planning and HIV policies and programs is now widely recognized by global health policymakers and donors. However, to date, most of the efforts to improve these linkages have been conducted in Africa. Greater attention is needed to the developing, implementing, and evaluating of integrated family planning/HIV approaches that are tailored to the political, cultural, and public health context in Asia. In this paper, we describe the use of and need for family planning among key populations affected by HIV in Asia, discuss the challenges to effectively addressing of these needs, and offer recommendations for strengthening the linkages between family planning and HIV policies and programs in the region.

Modern contraceptive and dual method use among HIV-infected women in Lusaka, Zambia

HIV-infected women in sub-Saharan Africa are at substantial risk of unintended pregnancy and sexually transmitted infections (STIs). Linkages between HIV and reproductive health services are advocated. We describe implementation of a reproductive health counseling intervention in 16 HIV clinics in Lusaka, Zambia. Between November 2009 and November 2010, 18,407 women on antiretroviral treatment (ART) were counseled. The median age was 34.6 years (interquartile range (IQR): 29.9–39.7), and 60.1% of women were married. The median CD4⁺ cell count was 394 cells/uL (IQR: 256–558). Of the women counseled, 10,904 (59.2%) reported current modern contraceptive use. Among contraceptive users, only 17.7% reported dual method use. After counseling, 737 of 7,503 women not previously using modern contraception desired family planning referrals, and 61.6% of these women successfully accessed services within 90 days. Unmet contraceptive need remains high among HIV-infected women. Additional efforts are needed to promote reproductive health, particularly dual method use.
