As part of the 2005 survey on knowledge, attitudes, beliefs, and behaviors regarding HIV/AIDS conducted by the National Institute for Prevention and Health Education (Inpes), 1,874 people from sub-Saharan Africa living in the Île-de-France region were interviewed in public places about HIV testing. Among those from sub-Saharan Africa, 64.9% reported having been tested at least once in their lifetime, and 34.2% reported having been tested multiple times. Testing was more common among French nationals or foreign nationals with stable residency status. Compared to the general population, the most recent test was more frequently performed at a hospital (30.4%) and was more often (61.2%) initiated by a doctor during a health checkup or as part of a screening protocol (prenatal or premarital examination). Very few tests were performed following risky behavior. Finally, populations from sub-Saharan Africa have a relatively high rate of testing, despite the barriers posed by an unstable administrative status. (R.A.)
