Evaluative nature of this research aims to evaluate the knowledge, attitude and practice of women prisoners on male and female condoms.

The study will be developed in a female penitentiary institution of the State of Ceará with a sample of 155 women. Data collection will happen in the period from March to May 2010 and will instrument the investigation Knowledge, Attitude and Practice (KAP) on the male and female condom use.
