Behavioral interventions for improving condom use for dual protection.

Unprotected sex is a major risk factor for disease, disability, and mortality in many areas of the world due to the prevalence and incidence of sexually transmitted infections (STI) including HIV. The male condom is one of the oldest contraceptive methods and the earliest method for preventing the spread of HIV. When used correctly and consistently, condoms can provide dual protection, i.e., against both pregnancy and HIV/STI.
