The purpose of this paper is to assess the extent to which epidemiolog
ical and public health topics and issues have affected the constructio
n of sexuality in the context of AIDS. The ACSF questionnaire was subm
itted to a dual analysis. It was presented and discussed in relation t
o its relevance for a scientific study of the problems raised, by the
organization that commissioned it. But it was also analysed in terms o
f its significance as a socially acceptable scenario for the discussio
n of sexuality in the context of AIDS. The analysis is focused on the
following : (1) the manner in which the questionnaire was presented to
respondents ; (2) the characteristics assigned to those who answered
the questions and those of the partners whom they reported and describ
ed ; (3) sexual practices, and (4) the << sexuality-risks-AIDS >> syst
em. It is shown that the whole questionnaire was shaped by the AIDS is
sue, since the investigation of sexual activity in the population is c
entered around the theme of AIDS.
