Description

An anonymised dataset containing details of a sub-study of 100 HIV-negative women in 2009. This sub-study was part of a microbicide feasibility study in North-West Tanzania that was carried out between 2008-2010. It contains information on sexual behaviour, vaginal practices, current contraception, STI symptoms, as well as results of a clinical and colposcopic examination.

Data access

This dataset cannot be made available via a repository due to ethical restrictions. Interested researchers may submit request for de-identified data to Saidi.Kapiga@lshtm.ac.uk.
