Women in Brazil have come together in a viral campaign to hit back at a shocking new study which found that 65.1 percent of the nation believed that "if dressed provocatively, women deserve to be attacked and raped."

The survey, carried out by the country's Institute for Applied Economic Research, interviewed 3,810 Brazilians about their attitude to rape. They also found that 58.5 percent agreed with the statement that, "if women knew how to behave, there would be less rape."

Even more alarmingly, 66.5 percent of those polled in the questionnaire were women. Presenting the findings, the institute revealed that 50.7 percent of rape victims in Brazil were under 13 at the time of abuse.

The survey triggered a flood of outraged commentary in Brazil over the weekend. Brazilian journalist Nana Queiroz was quick to respond, setting up a Facebook page and hashtag "#NãoMereçoSerEstuprada" - which translates as "#IDon'tDeserveToBeRaped" - in protest.

The campaign called for women to post photos of themselves, either topless or fully clothed, holding a sign with the hashtag to rally against the survey's findings and "to demonstrate that no one can claim ownership over their bodies."

Thousands of women responded, taking to Twitter and Facebook to express their shock and anger.

"Clothes do not define character!! #No woman deserves to be raped. #I don't deserve to be raped," one woman wrote, as two others posted photos of their stomachs with the message, "I belong to me" scrawled across them.

Men also joined the campaign, with many posting signs that read, "No woman deserves to be raped."

The institute estimated that 0.26 percent of the Brazilian population have been victims of sexual abuse, but only 10% of rape cases are reported. It found that of the rape cases reported in 2011, 89 percent of victims were women, with a firearm used in one out of every five cases.
