Long distance truck drivers. 2: Knowledge and attitudes concerning sexually transmitted diseases and sexual behaviour.

Three hundred and thirty seven truck drivers, in transit from Mombasa to destinations within east and central Africa were interviewed on their knowledge on AIDS and sex practices using a pre-defined questionnaire. Nearly all of them, 99% (3.7/321), had heard of AIDS through mass media and from friends. When asked for a definition of AIDS, 87% (336/485 responses) described it as a sexually transmitted disease (STD) which causes body wasting and death. The majority were aware of the correct risk reducing behaviours: 76% (228/300) knew that use of condoms can prevent the transmission/acquisition of STDs but only 32% (90/295) had ever used them. This was in spite of the fact that 61% (226/309) admitted to visiting prostitutes. Various reasons were given for not using condoms. About 32% (34/188) claimed that they did not sleep with prostitutes while 18% (34/188) did not see the need for using condoms. Condoms were unavailable to another 18% (34/188). The data obtained show a clear lack of correlation between the correct knowledge of AIDS and application in the prevention of acquisition and transmission of STD.
