Predictors of diaphragm use as a potential sexually transmitted disease/HIV prevention method in Zimbabwe

Background: Women who are the most vulnerable to sexually transmitted diseases/HIV are often unable to consistently use condoms. One potential alternative method currently under investigation is the diaphragm. Goals: The goals of this study were to assess diaphragm uptake and use over time in Zimbabwe and to identify factors associated with self-reported consistent diaphragm use. Study: Women attending family planning clinics who were inconsistent condom users received a diaphragm intervention and were followed for 6 months. Results: Of the 186 participants, 99% ever reported using the diaphragm, and, at study exit, 96% had used it in the previous 2 months. Consistent diaphragm use since the previous visit was reported by 13% to 16% of the women, and in multivariate regression analysis, it was significantly associated with never using condoms (adjusted odds ratio, 24.08; 95% confidence interval, 6.71-86.34). Other factors included discreet use, preferring diaphragms to condoms, timing of insertion, domestic violence, and contraception. Conclusion: Diaphragms were well accepted among women at risk for sexually transmitted diseases/HIV.
