简要总结
Intravaginal practices (IVP) (cleansing or introducing products inside the vagina for hygiene, health or to please sexual partners) are common among women with HIV. IVP increase the risk of developing bacterial Vaginosis (BV), the most common genital infection associated with transmission of sexually transmitted infections and HIV. This study tested a pilot intervention to reduce IVP and BV in HIV infected women in Zambia. A total of 128 HIV infected women engaging in IVP were randomized to two conditions: enhanced standard of care (n = 70) and experimental (n = 58). All participants received a brief educational counseling session on discontinuation of IVP, and those with BV, were provided with medical treatment for BV. Women in the experimental condition received an additional group-based, culturally tailored intervention. Participants completed questionnaires assessing sexual risk factors and IVP and were assessed for BV using Nugent criteria at baseline, 6 months and 12 months.
详细描述
Zambia has high rates of women of childbearing age infected with Human Immune Deficiency Virus (HIV). The majority (93%) engage in intravaginal practices (here referred to as IVP) by internal cleansing (intravaginal cleansing) or by inserting products inside the vagina (intravaginal insertion). IVP are culturally driven practices associated with an increased risk of HIV transmission and may play an important role in exacerbating the HIV epidemic across sub-Saharan Africa.
This application proposes to 1) evaluate the long term impact of a bio-behavioral intervention targeting VP among HIV infected women (n=128) in Lusaka, Zambia, and 2) assess the relative contributions of VP and bacterial vaginosis (BV) to lower genital tract inflammation and HIV shedding. Study aims will address the following:
Aim 1. To develop and evaluate the long term impact of a culturally tailored bio-behavioral intervention aimed to decrease IVP in HIV positive women and evaluate the relative contribution of IVP and BV to lower genital inflammation and shedding of HIV.
Aim 1.1. To develop and evaluate the long term impact of a bio-behavioral intervention to decrease IVP.
Intra vaginal practices, as culturally driven and condoned behaviors, are difficult to modify. It is hypothesized that a culturally tailored bio-behavioral intervention is needed to decrease IVP, and that women participating in the intervention condition will reduce IVP in comparison with women in a time matched control condition. Experimental approach: Women engaging in IVP will be randomly assigned to one of two conditions (intervention or control). IVP will be evaluated and compared over 12 months.

盲法说明
The study statistician did not participate in randomization and the recruiter and laboratory personnel were blinded to the condition assignment. The participant was blind to their condition assignment. The reading of all the slides used to diagnose BV was performed by one trained laboratory technician blinded to the participant condition assignment. In case of unclear reading, the slide was reviewed by a second technician and the chief of the laboratory until an agreement was achieved; both the second technician and the chief of the laboratory were blind to the condition assignment of the participant.

时间窗: 12-months
Information on intravaginal practices was collected using a culturally tailored questionnaire assessing specific products used for IVP. Questions to assess product use in the prior month utilized a dichotomous response option: product use (1 = yes, 0 = no).
