Sexual and reproductive health (SRH) and rights are important components of quality of life. This cross-sectional study describes HIV-positive women's SRH aspirations and needs and the predictive value of selected SRH factors on condom use with steady sexual partners. Data were collected in a European multi-centre study in 17 HIV centres in 14 European countries by a standardised anonymous self-administered questionnaire. Descriptive statistics and hierarchical regression analysis were carried out and qualitative data from related formative research illustrated the findings. Among 387 HIV-positive women, 57% had children and 35% had become pregnant since their HIV-diagnosis. Contraceptive needs were largely unmet: 14% had undergone a pregnancy termination. About 83% changed their sexual behaviour after HIV-diagnosis in some ways. Sixty-two percent had at least one sexual encounter with a steady partner during the past six months and 51% used condoms consistently. Significant correlations with condom use were identified for childbearing since HIV-diagnosis (r=-0.21, p<0.01), miscarriage since HIV-diagnosis (r=-0.24, p<0.01), the use of contraception (r=0.47, p<0.001) and changes in sexual behaviour after HIV-diagnosis (r=0.20, p<0.01). Hierarchical regression analysis controlled for education, migration background, age, undetectable viral load and partners' serostatus. The following significant predictors for condom use were established: the use of contraceptives (β=0.33, p<0.001); miscarriage since HIV-diagnosis (β=-0.16, p<0.01); childbearing since HIV-diagnosis (β=-0.12, p<0.05); and having an HIV-positive partner (β=-0.13, p<0.05). For study population, consistent condom use performed a challenge. Selected SRH-issues predicted condom use. Sexual risk reduction and positive prevention should be discussed in the context of family planning and integrate SRH perspectives in routine HIV care. [ABSTRACT FROM AUTHOR]

- Abstract
To prevent hepatitis C virus (HCV) reinfection, within the Swiss HCVree Trial , a preventive risk reduction intervention was implemented alongside curative treatment. Formative qualitative research identified three response patterns to the intervention. This mixed-methods study's aim was to cross-validate group differences in (a) the content of sexual risk reduction goals set during intervention and (b) the extent of their behavioural change in condomless anal intercourse with non-steady partners (nsCAI), sexualised and intravenous drug use at start and six-month post-intervention. Qualitative thematic analysis was used to summarise goal setting domains. Quantitative descriptive analysis was used to evaluate group differences based on assumptions of the group descriptions. Results largely confirmed assumptions on inter-group response differences in goal setting and behaviour: as expected group 1 Avoid risks showed the lowest HCV risk profile with changes in nsCAI. Group 2 Minimize-risks and Group 3 Accept-risks showed unchanged nsCAI. Group 3 had the highest HCV risk profile. Differences in their goal preferences (1: condom use; 2 reduction blood exposure; 3 safer dating) highlight diversity in attitudes to behavioural change. Our results improve understanding of variability in intervention responses such as changes in attitudes and behaviour. This provides evidence for intervention tailoring and outcome measurement.

- Abstract
Little is known about how interacting psychosocial problems may influence sexual behaviour among men having sex with men taking Pre-exposure prophylaxis (PrEP). This study assessed (1) the prevalence of depression, recreational drug-use and sexual risk behaviour; (2) changes in these psychosocial conditions over time; and (3) the interaction of drug use and depression with sexual risk behaviour. We analysed data of the Belgian Be-PrEP-ared cohort study ( N = 200). We assessed depression using the PHQ-9, recreational drug use and receptive condomless anal intercourse (rCAI) with anonymous partners. Frequencies of psychosocial problems were compared at baseline, 9 and 18 months follow-up (FU). Bivariate associations between depression and drug-use behaviour, and their interaction with rCAI with anonymous sexual partners using was examined using linear regression. Receptive CAI increased from 41% at baseline to 53% at M18 ( p = 0.038). At baseline, we found an interaction effect of poly-drug use and depression, potentiating rCAI with anonymous partners. Participants reporting poly-drug use associated with depression were significant more likely to report this type of sexual risk behaviour than those who did not report this association ( p = 0.030). The high level of intertwined psychosocial problems call for multi-level interventions for those PrEP users experiencing a syndemic burden.

- Abstract
Community-based participatory research (CBPR) has received considerable attention during past decades as a method to increase community ownership in research and prevention. We discuss its application to epidemiological research using the case of second-generation surveillance conducted among sub-Saharan African (SSA) migrants in Antwerp city. To inform evidence-based prevention planning for this target group, this HIV-prevalence study used two-stage time-location sampling preceded by formative research. Extensive collaborative partnerships were built with community organizations, a Community Advisory Board provided input throughout the project, and community researchers were trained to participate in all phases of the seroprevalence study. Valid oral fluid samples for HIV testing were collected among 717 SSA migrants and linked to behavioural data assessed through an anonymous survey between December 2013 and August 2014. A qualitative content analysis of various data sources (extensive field notes, minutes of intervision, and training protocols) collected at 77 data collection visits in 51 settings was carried out to describe experiences with challenges and opportunities inherent to the CBPR approach at three crucial stages of the research process: building collaborative partnerships; implementing the study; dissemination of findings including prevention planning. The results show that CBPR is feasible in conducting scientifically sound epidemiological research, but certain requirements need to be in place. These include among others sufficient resources to train, coordinate, and supervise community researchers; continuity in the implementation; transparency about decision-taking and administrative procedures, and willingness to share power and control over the full research process. CBPR contributed to empowering community researchers on a personal level, and to create greater HIV prevention demand in the SSA communities.

- Abstract
Adolescents living with HIV (ALHIV) face many psychosocial challenges, including HIV disclosure to others. Given the importance of socialization during the adolescent transition process, this study investigated the psychological and social factors influencing self-disclosure of own HIV status to peers. We examined social HIV self-disclosure to peers, and its relationship to perceived HIV-related stigma, self-efficacy to disclose, self-esteem, and social support among a sample of n = 582 ALHIV aged 13-17 years in Kampala, Uganda, and Western Kenya. Data were collected between February and April 2011. Among them, 39% were double orphans. We conducted a secondary data analysis to assess the degree of social disclosure, reactions received, and influencing factors. Interviewer-administered questionnaires assessed medical, socio-demographic, and psychological variables (Rosenberg self-esteem scale; self-efficacy to disclose to peers), HIV-related stigma (10-item stigma scale), and social support (family-life and friends). Descriptive, bivariate, and logistic regression analyses were performed with social self-disclosure to peers with gender as covariates. Almost half of ALHIV had told nobody (except health-care providers) about their HIV status, and about 18% had disclosed to either one of their friends, schoolmates, or a boy- or girlfriend. Logistic regression models revealed that having disclosed to peers was significantly related to being older, being a paternal orphan, contributing to family income, regular visits to the HIV clinic, and greater social support through peers. Low self-efficacy to disclose was negatively associated to the outcome variable. While social self-disclosure was linked to individual factors such as self-efficacy, factors relating to the social context and adolescents' access to psychosocial resources play an important role. ALHIV need safe environments to practice disclosure skills. Interventions should enable them to make optimal use of available psychosocial resources even under constraining conditions such as disruptive family structures.

- Abstract
As anti-retroviral therapy becomes increasingly available, young people living with HIV need tailored support to adopt healthy sexual behaviors. There has been a gap in the availability of culturally appropriate techniques for secondary prevention and sexual risk reduction in this target group. This formative study assessed sexual and reproductive health needs and problems, as well as determinants of sexual risk-taking among young people living with HIV aged 11-21 years attending the Paediatric Infectious Disease Clinic in Kampala, Uganda. Theoretical guidance was provided by the Information-Motivation-Behavioral Skills Model. Socio-demographic and selected psychosexual data were assessed using a brief anonymous questionnaire. A total of 75 young people living with HIV participated in eight focus group discussions. In addition, one focus group was conducted with adult key informants (service providers). About a quarter of the young participants reported prior or current sexual experience. The study revealed knowledge gaps relating to reproductive health, HIV transmission, and contraceptive methods. Motivations for protection included hope for the future, good counseling, and fear of the consequences of sexual activity such as unwanted pregnancies. Barriers to adopting preventive behaviors included peer pressure, poverty, HIV-related stigma, ignorance of their partners, alcohol use, and a desire to have children for the older ones. Young sero-positive people in this setting lacked specific behavioral skills, such as disclosure of HIV status to their sexual partners, this being closely linked to fear of rejection and stigma. HIV-positive youths need support in developing the appropriate behavioral skills to adopt healthy sexual behaviors. Interventions in this field need to be developmentally appropriate and tailored to young people's specific needs. Structural interventions should at the same time address and reduce HIV-related stigma and socio-economic needs of young people living with HIV.
