Prostate-specific antigen to ascertain reliability of self-reported coital exposure to semen

Objective: The objective of this study was to assess the validity of women’s reports of recent unprotected sex by testing for prostate-specific antigen (PSA) in vaginal samples. Study Design: The authors conducted prospective research with 332 female sex workers attending 2 public dispensaries in Madagascar. Results: Among women who reported no sex or protected sex only within the past 48 hours, 21% and 39%, respectively, tested positive for PSA. Among those testing positive for PSA, no differences in PSA concentrations were found among those reporting no sex, protected sex only, or at least one unprotected act. Conclusions: The substantial disagreement between self-reports and measurement of a biologic marker of semen exposure in vaginal specimens substantiates that self-reports of sexual behavior cannot be assumed to be valid measures. Future sexually transmitted infection/HIV and pregnancy prevention studies should confirm the validity of self-reports or use end points that do not rely on self-reported data.

Temporal Trends in Sexually Transmitted Infection Prevalence and Condom Use Following Introduction of the Female Condom to Madagascar Sex Workers

We followed 1000 sex workers in Madagascar for 18 months to assess whether adding female condoms to male condom distribution led to increased protection levels and decreased sexually transmitted infections (STIs). For months 1–6, participants had access to male condoms only; in the final 12 months, they had access to male and female condoms. We interviewed participants about condom use every two months and tested for chlamydia, gonorrhoea and trichomoniasis every six months. Following six months of male condom distribution, participants used protection in 78% of sex acts with clients. Following female condom introduction, protection at months 12 and 18 rose to 83% and 88%, respectively. Aggregate STI prevalence declined from 52% at baseline to 50% at month 6. With the female condom added, STI prevalence dropped to 41% and 40% at months 12 and 18, respectively. We conclude female condom introduction is associated with increased use of protection to levels that reduce STI risk.

Integration of family planning into HIV services: a synthesis of recent evidence.

Introduction:Increasing access to contraception among women who enter the health system for HIV care is crucial to help them achieve their fertility intentions and reduce vertical transmission of HIV. Identifying intervention strategies that contribute to effective family planning/HIV service integration and synthesizing lessons for future integration programming and research is important to move the field forward. Methods:Using a standard review methodology, we searched for articles in the peer-reviewed literature published between January 2008 and August 2013 that addressed the integration of family planning interventions into HIV service settings. Eligible studies were assessed in terms of methodological rigor; documented outcomes; and reported process and cost data. Results:Twelve studies met our inclusion criteria. Eight studies documented significant increases in contraceptive use by HIV service clients, and three reported significant increases in completed referrals from HIV services to family planning clinics. The outcomes of the seven studies implemented in public sector facilities were more modest than the five studies embedded in clinical trials. Process evaluation measures for some of the studies indicated weak implementation of the intervention as intended. The average rigor score was low, 3.4 out of 9. Conclusion:Our review reveals an expanding evidence base for integrated family planning/HIV service delivery innovations. However, the modest observed effect under typical settings and the evidence of weak intervention implementation emphasize the need for stronger programmatic efforts and implementation research to address the health system obstacles to integrating these two essential services.

Effect of consistent condom use on 6-month prevalence of bacterial vaginosis varies by baseline BV status.

Objectives  Bacterial vaginosis (BV) is a condition characterized by a disturbed vaginal ecosystem which fluctuates in response to extrinsic and intrinsic factors. BV recurrence is common. To explore whether consistent condom use was associated with BV occurrence or recurrence, we compared the effect of condom use on BV prevalence after 6 months, among women with and without BV at baseline.

Randomised controlled trial of alternative male and female condom promotion strategies targeting sex workers in Madagascar

Objectives: To assess whether individual clinic-based counselling as a supplement to peer education for male and female condom promotion leads to greater use of protection and lower STI prevalence among sex workers in Madagascar already exposed to intensive male condom promotion. Methods: In two public dispensaries in Madagascar, a total of 901 sex workers were randomly allocated between two alternative male and female condom promotion interventions: peer education only, or peer education supplemented with individual clinic-based counselling. Participants were followed for 12 months. Every 2 months they made clinic visits, where they were interviewed on condom use. Peer educators counselled all participants on condom use as they accompanied their assigned participants to study visits. Participants assigned to receive the supplemental intervention were counselled by a trained clinician following study interviews. Participants were tested and treated for chlamydia, gonorrhoea and trichomoniasis every 6 months. We used logistic regression to assess whether the more intensive intervention was associated with reduced STI prevalence. Use of protection with clients and non-paying partners was assessed by study arm, site, and visit. Results: There was no statistically significant association between study arm and aggregated STI prevalence. No substantial differences in levels of reported protection were noted between study groups. Conclusions: This study found little evidence for gains from more thorough clinical counselling on male and female condom use. These findings suggest that less clinically intensive interventions such as peer education could be suitable for male and female condom promotion in populations already exposed to barrier method promotion.

Expanding contraceptive options for PMTCT clients: a mixed methods implementation study in Cape Town, South Africa

BackgroundClients of prevention of mother-to-child transmission (PMTCT) services in South Africa who use contraception following childbirth rely primarily on short-acting methods like condoms, pills, and injectables, even when they desire no future pregnancies. Evidence is needed on strategies for expanding contraceptive options for postpartum PMTCT clients to include long-acting and permanent methods.MethodsWe examined the process of expanding contraceptive options in five health centers in Cape Town providing services to HIV-positive women. Maternal/child health service providers received training and coaching to strengthen contraceptive counseling for postpartum women, including PMTCT clients. Training and supplies were introduced to strengthen intrauterine device (IUD) services, and referral mechanisms for female sterilization were reinforced. We conducted interviews with separate samples of postpartum PMTCT clients (265 pre-intervention and 266 post-intervention) to assess knowledge and behaviors regarding postpartum contraception. The process of implementing the intervention was evaluated through systematic documentation and interpretation using an intervention tracking tool. In-depth interviews with providers who participated in study-sponsored training were conducted to assess their attitudes toward and experiences with promoting voluntary contraceptive services to HIV-positive clients.ResultsFollowing the intervention, 6% of interviewed PMTCT clients had the desired knowledge about the IUD and 23% had the desired knowledge about female sterilization. At both pre- and post-intervention, 7% of clients were sterilized and IUD use was negligible; by comparison, 75% of clients used injectables. Intervention tracking and in-depth interviews with providers revealed intervention shortcomings and health system constraints explaining the failure to produce intended effects.ConclusionsThe intervention failed to improve PMTCT clients’ knowledge about the IUD and sterilization or to increase use of those methods. To address the family planning needs of postpartum PMTCT clients in a way that is consistent with their fertility desires, services must expand the range of contraceptive options to include long-acting and permanent methods. In turn, to ensure consistent access to high quality family planning services that are effectively linked to HIV services, attention must also be focused on resolving underlying health system constraints weakening health service delivery more generally.

Evaluation of a male engagement intervention to transform gender norms and improve family planning and HIV service uptake in Kabale, Uganda

ABSTRACT Men’s limited understanding of family planning (FP) and harmful cultural gender norms pose obstacles to women’s FP use. Thirty-two model men called ‘Emanzis’ were recruited from the community in Kabale, Uganda to lead men from their peer group through a 10-session curriculum designed to transform gender norms and motivate men to engage in FP and HIV services. Cross-sectional surveys were conducted before (n = 1251) and after (n = 1122) implementation. The Gender Equitable Men (GEM) Scale was used to assess the effect on gender attitudes. The intervention achieved negligible changes in responses to GEM items. Improvements in some gender-influenced health-seeking behaviours and practices in men were noted, specifically in visiting health facilities, HIV testing, and condom use. For future application, the intervention should be adapted to require higher peer educator qualifications, longer intervention duration, and more frequent supervision. Practical guidance is needed on where to direct investments in gender-transformative approaches for maximum impact.

Is 'planning' missing from our family planning services?

1The benefits of family planning, in developing countries in particular, extend beyond decreasing fertility and include poverty reduction, improved health for both mother and child, the promotion of gender equality by increasing women’s opportunities beyond reproductive and domestic activities, and environmental sustainability. 1 In addition, prevention of undesired pregnancies among HIV-positive women by eliminating unmet need for contraception is a highly cost-effective means of preventing mother-to-child transmission. 2 In South Africa, free contraceptives are available at public sector health care facilities, and contraception use is high: an estimated 65% of sexually active women use a method. 3 The method mix comprises predominantly short-acting methods – primarily injectable contraceptives. Long-acting contraceptives, such as the intra-uterine device (IUD), are highly effective among typical users owing to consistency of function, yet are underutilised in South Africa’s public sector facilities. Of importance, especially in South Africa’s high HIVprevalent setting, is that the IUD can be safely used on clinically well HIV-positive women. 4 The 2004 Demographic and Health Survey showed that 10% of sexually active women were sterilised, while less than 1% of women were using the IUD. 3 In preparation for an intervention aimed at improving contraceptive options, including long-acting and permanent methods (LAPM), for all postpartum women, we assessed women’s knowledge and attitudes to LAPM. We report on findings from our baseline survey, which have prompted the question: Where is the ‘planning’ in family planning services?

Baseline infection with a sexually transmitted disease is highly predictive of reinfection during follow-up in Malagasy sex workers.

Female sex workers who had prevalent chlamydial, gonococcal, or trichomonal infection at enrollment into a randomized trial in Madagascar were 2 to 4 times as likely to become infected during follow-up, compared to women without STIs at baseline, despite provision of condoms, safer sex counseling, and repeat STI testing and treatment.

Condom use and sexually transmitted infections among Malagasy sex workers

We evaluated whether use of a short- or longer-term recall period for condom use was superior for assessing risk of acquisition of incident sexually transmitted infection (STI). Female sex workers (n = 1000) in Madagascar took part in a randomized trial comparing counselling strategies for male and female condom promotion. We explored associations between womens self-reported condom use with clients and non-paying partners and incident STI, examining both short-term recall (last sex act) and longer-term recall (over the past month and year). Self-reported condom use was generally not associated with reduced STI risk, whether measured at the last act or over longer time periods; with clients or non-paying partners; and through unadjusted and adjusted modelling. No condom use measure (short versus longer time periods, with one or both partner types) was strongly predictive of STI, suggesting poor validity.
