'I married when I was 16 due to poverty, I had no other way': multi-level factors influencing HIV-related sexual risk behaviours among adolescent girls in Zambézia, Mozambique.

This paper explores individual, interpersonal- and household-level factors influencing HIV-related sexual risk behaviour among adolescent girls who participated in an intervention to reduce HIV risk in a rural setting in Mozambique. Twenty-eight adolescent girls ages 13-19, 30 heads of household, and 53 influential men participated in in-depth interviews at two time points. Comparative analysis compared girls who reported reducing risk behaviours over time to girls who did not and identified factors that respondents described as influential to behaviour change. Among the twenty girls self-reporting sexual risk at the first time point, half had reduced these behaviours one year later. Changes in girls' behaviours were contingent upon household- and interpersonal-level factors, particularly households' economic stability and family members' financial support. Future interventions with adolescents in similar settings should evaluate and leverage household and family support to achieve sexual risk reduction.

Quasi-experimental evaluation using confirmatory procedures: A case study of an economic and social empowerment intervention to reduce girls' vulnerability to HIV in rural Mozambique.

PURPOSE: Our goal was to determine whether an economic and social empowerment intervention implemented in Zambézia Province, Mozambique reduced girls' vulnerability to HIV. We use this experience to discuss challenges of evaluating real-world interventions. METHODS: Two rounds of data were collected from 885 girls, 13-19 years, for this clustered, non-equivalent (two-stage) cohort trial. We used multi-level exact matching and difference-in-differences estimation to estimate intervention effects on two outcomes: girls' knowledge of gender-based violence and school attendance. RESULTS: Estimates of two outcomes analysed indicated no statistically significant intervention effects. Preliminary analysis of data from the intervention group revealed this study was unable to obtain accurate measures for five outcomes related to HIV vulnerability. CONCLUSIONS: Although our study did not find evidence of impact on the a priori selected outcomes, we report on our experience implementing this robust methodologic design and describe how the challenges encountered in this program setting affected our ability to attain results. We recommend prospective evaluation designs with random allocation be accommodated early during planning. When not possible, quasi-experimental studies should collect data from large samples. To reduce measurement bias, biological endpoints such sexually transmitted infections should serve as primary outcomes for programs intending to reduce sexual behaviors.

A longitudinal qualitative evaluation of an economic and social empowerment intervention to reduce girls' vulnerability to HIV in rural Mozambique.

PURPOSE: An intervention including business training and health education was implemented in Mozambique, where girls are at elevated risk for acquiring HIV. As part of a mixed-methods evaluation, we describe perceived effects of the intervention on girls' sexual behavior and school attendance. METHODS: We conducted 49 in-depth interviews (IDIs) with girl intervention participants (ages 13-19), 24 IDIs with heads of girls' households, 36 IDIs with influential males identified by girls, and 12 focus group discussions with community members after the intervention ended and one year later. RESULTS: Informants said the primary intervention benefit was realized when girls had money to stay in or return to school and/or to buy necessities for themselves and their households-reducing their need for transactional or intergenerational sex. However, some girls did not make a profit and some businesses were not sustainable. Sometimes the intervention appeared to be implemented in a way to reinforce inequitable gender norms resulting in some girls feeling shame when they reengaged in risky sex after their businesses failed. CONCLUSIONS: Earning money enabled girls to potentially reduce their vulnerability to HIV. We offer recommendations for future multi-sector interventions, including the need to address potential harms in programs serving vulnerable girls.

Correlates of Rapid Repeat Pregnancy Among Adolescents and Young Women in Uganda.

CONTEXT: Short pregnancy intervals can contribute to maternal and child morbidity and mortality. No previous research has explored factors associated with short pregnancy intervals among young women in Uganda, where adolescent pregnancy and short birth intervals are common. METHODS: Data on 626 married or cohabiting women aged 15-22 with one or two previous pregnancies were drawn from the 2011 Uganda Demographic and Health Survey. Bivariate and multivariable logistic regression analyses were used to examine characteristics associated with rapid repeat pregnancy, defined in two ways: a pregnancy occurring within 24 months or 12 months of a prior pregnancy outcome. RESULTS: Among women, 74% and 37% had experienced a rapid repeat pregnancy within 24 months and 12 months, respectively. Rural women were more likely than urban women to have had a rapid repeat pregnancy within 24 months (odds ratio, 2.4). Women aged 15-17 and those 18 or older at first union were more likely than women younger than 15 to have had a rapid repeat pregnancy within 24 months (3.8 and 3.4); those whose partner had at least a secondary education had lower odds than others of the outcome (0.6). The odds of rapid repeat pregnancy increased with the number of months between marriage and first birth (1.05). Variables associated with rapid repeat pregnancy within 12 months included urban-rural residence, region, age at first union and marriage-to-birth interval. CONCLUSIONS: Efforts to reduce rapid repeat pregnancy among young women in Uganda should focus on rural areas. Strategies to reach women during antenatal care and the postpartum period after their first birth should be prioritized.

Assessment of the psychometric properties of HIV knowledge items across five countries.

HIV knowledge is commonly measured in HIV prevention research and program evaluations, but rigorous measurement standards are not always applied. Using item response theory methods, we examined the psychometric functioning of five commonly used HIV knowledge questions in five countries with varying HIV prevalence. We evaluated the internal consistency and measurement invariance of the items. The items performed poorly in all samples and the scale as a whole did not perform equally across samples. We conclude that current ways of measuring HIV knowledge are not adequate and recommend new items be developed, tested, and validated using psychometric methods.

Qualitative study of reasons for discontinuation of injectable contraceptives among users and salient reference groups in Kenya.

Discontinuation of contraception is a major problem in Kenya. Even though they want to space or limit their births, over a quarter of contraceptive injectable users discontinue use of the method within 12 months of beginning use. Fourteen focus group discussions were conducted in Nyando District, Kenya among current contraceptive injectable users and their salient reference groups (e.g. husbands, mothers-in-law, community leaders, service providers) to understand why women discontinue using contraceptives (with a focus on injectables). Thematic analysis was performed using NVivo 8 software. Discontinuation of contraceptives in Nyando District occurs for logistical, social and medical reasons. Common reasons for discontinuation include side effects, husbands' opposition, provider and/or clinic restrictions, misconceptions about injectables, stock outs, and lack of cash to pay for family planning services. This research expands the literature by examining social influences on discontinuation by incorporating the perspectives of salient reference groups. The results suggest points of intervention for increasing continuation in this community and similar resource-poor settings.

Partnering for Care in HIV Prevention Trials.

QUALITATIVE CASE STUDIES WERE conducted at seven international sites conducting HIV prevention research in Africa, Asia, and the Americas to identify strategies for ensuring that health needs of research participants identified in the course of research are adequately addressed. Key factors were identified that contribute to the balance between direct care and healthcare referrals at a research site, as well as the overall quality of the healthcare made available to research participants. The case studies exemplify the concept of "moral negotiation" in research (Weijer & LeBlanc, 2006), that is, a process where researchers and sponsors negotiate with increasingly empowered local communities and host countries to achieve meaningful and substantive benefits from biomedical research for all stakeholders.

Exposure to MTV's global HIV prevention campaign in Kathmandu, Nepal; São Paulo, Brazil; and Dakar, Senegal.

In 2002 MTV aired a global media campaign, "Staying Alive," to promote HIV prevention among 16- to 25-year-olds. Skeptics believed that a global MTV campaign would reach only a small group of elite young people. MTV increased access to its campaign, however, by making all materials "rights free" to third-party (non-MTV) broadcasters. Over 789 million households in over 166 countries had access to some or all of the campaign. To understand the level of actual exposure and the types of young people exposed, data were analyzed from population-based household surveys in three diverse urban areas where a campaign evaluation was conducted: Kathmandu, Nepal; São Paulo, Brazil and Dakar, Senegal. Exposure rates ranged from 12% in Kathmandu, 23% in São Paulo, and 82% in Dakar, reaching an estimated 32,000, 400,000, 220,000 16- to 25-year-olds in each city, respectively. A number of personal, social and economic characteristics found to predict campaign exposure were identified in each site; in general, these were related to economic status and use of "new" media technologies. Though this skew toward more exposure by those with greater resources existed, we found that the campaign audience was in no way composed only of "elite" young people. (For example, although more of those exposed to the campaign had used the Internet compared with those not exposed, this was not the majority of those exposed in most countries.) The possibility of reaching millions of young people through global networks with minimal marginal costs after production, creates a new paradigm for reaching an important segment of young people.

MTV's "Staying Alive" global campaign promoted interpersonal communication about HIV and positive beliefs about HIV prevention.

In 2002 MTV launched a global multicomponent HIV prevention campaign, "Staying Alive," reaching over 166 countries worldwide. An evaluation of this campaign focused on three diverse sites: Kathmandu, Nepal; São Paulo, Brazil; and Dakar, Senegal. Data were collected before and after campaign implementation through population-based household surveys. Using linear regression techniques, our evaluation examined the effects of campaign exposure on interpersonal communication about HIV and the effects of campaign exposure and interpersonal communication on beliefs about HIV prevention. We found a consistent positive effect of exposure on interpersonal communication across all sites, though there were differences among sites with regard to whom the respondent talked about HIV. We also found a consistent positive effect of exposure on HIV prevention beliefs across sites when interpersonal communication was simultaneously entered into the model. Finally, in two sites we found a relationship between interpersonal communication and HIV prevention beliefs, controlling for exposure, though again, the effects differed by the type of person the communication was with. These similar findings in three diverse sites provide ecological validity of the findings that "Staying Alive" promoted interpersonal communication and influenced young people's beliefs about HIV prevention in a positive way, evidence for the potential of a global media campaign to have an impact on social norms.

Does MTV reach an appropriate audience for HIV prevention messages? Evidence from MTV viewership data in Nepal and Brazil.

In response to the growing numbers of young people affected by HIV around the world, MTV (Music TV), the world's largest television network, has aired a global HIV prevention campaign since 1999, expanding it into a multicomponent campaign in 2002. Questions have been raised, however, about whether MTV is an appropriate channel for these messages, given its provocative content and its reach to those at the upper end of the socioeconomic scale. To address questions about who MTV reaches, viewership data were analyzed from baseline surveys conducted as part of an evaluation of the 2002 HIV prevention campaign. The two sites included in this analysis were Kathmandu, Nepal, and São Paulo, Brazil-each with very different cultures and media environments. We found that, in general, heavier viewers of MTV are younger, better educated, and more dependent on their parents, and they have more access to satellite television and the Internet. MTV viewing was associated with positive attitudes toward HIV prevention behaviors (except for abstinence until marriage) but not with premarital sexual activity.
