Comparison of sexual behavior data collected using a coital diary and a clinic-based interview during a microbicide pilot study in Mwanza, Tanzania.

BACKGROUND: The performance of coital diaries (CDs) and clinic-based interviews to measure sexual behavior was compared during a pilot study for a Phase III microbicide trial. METHODS: In Mwanza, 59 women were enrolled for 4 weeks and provided with 20 placebo gels. Weekly, women were given CDs to complete daily. At the final clinic visit, women attended a face-to-face interview (Clinic FFI) about their sexual behavior, and the gel use was accounted for (gel accountability (GA)). Comparisons were made between CD, Clinic FFI, and GA data. In-depth interviews following clinic visits elicited reasons for discrepancies in reports. RESULTS: Twice as many sex acts during 1 week were recorded in the CD (median 4) compared with the clinic FFI (median 2). At the clinic FFI, more women reported using the gel for each sex act (84% vs. 40%; P < 0.001) and vaginal washing for each sex act (98% vs. 56%; P < 0.001) compared with the CD. Over 4 weeks, 16.4% of women recorded sex during menstruation in CDs compared with 1.8% at the clinic visit (P = 0.01). The median number of gels used reported in the CDs was the same as the GA (10) with 59% agreement on the number used within +/-2 gels. Reasons for misreporting during clinic FFI were reported to have been poor recall, embarrassment, or misunderstanding. Inaccuracies in CDs were attributed to misunderstanding or poor recording. CONCLUSIONS: CDs elicited higher recording of sex acts and lower reporting of gel use than clinic FFIs, which has implications for measuring adherence during clinical trials. With clear instructions and support, coital dairies should be considered in future microbicide trial design.

Risk and protective factors for HIV among orphans and non-orphans in Tanzania.

The objectives of this study were to identify risk and protective factors for engaging in unsafe sex among orphans and non-orphans and to explore whether risk and protection differs by gender and orphan status. The study was carried out in Kisesa ward, in the Mwanza region of Northwest Tanzania. A combination of in-depth interviews and focus group discussions were used to collect data from girls and boys as well as from the female caregivers of orphans. Findings revealed that among young people who reported having unsafe sex, those who were female orphans were more likely to state that they 'had to have sex' to acquire food and clothing for their households. Caregivers believed that many young people who engage in sexual-risk behaviours do so because they are not provided with adequate supervision and moral guidance. The study suggests that programmes may need to target both girls and young women and their caregivers and create access to education and decent work opportunities.
