 AB    OBJECTIVE: To study the spread of HIV in the heterosexual general
       population and the impact of the correction of the discrepancies
       frequently noted in sexual behavior survey between male and female
       sexual partner reports concerning number and age of sexual partners.
       METHODS: We used socio-demographic data collected by the ACSF French
       survey on a random sample of 20,000 persons in 1992. To represent
       precisely the sexual behavior characteristics (such as the yearly number
       of new partners, the frequency of sexual practices, the duration of
       partnerships and the ages of the partners), we developed a discrete
       event simulation model which describes the life history of each
       individual and the sexual network dynamics. During the simulation, the
       model uses distributions estimated from the ACSF data, according to age
       and gender, to determine the yearly rate of sex partner change and the
       ages of the partners (i.e. mixing matrices). Discrepancies between
       female and male reports concerning age and number of sex partner are
       quantified and these distributions are modified based on either female
       or male responses in order to balance the supply and demand of sexual
       partnerships. RESULTS: The ratio of male to female reports in the yearly
       number of sex partner varies from 1.1 to 2.7 between age classes and is
       the greatest for the youngest age group. The predicted epidemic is
       greater when the distributions of the rate of partner change and the
       mixing matrices are adjusted to the male rather than to the female
       responses. When using the male responses, the epidemic is enhanced if
       underreporting of the number of partners is concentrated among
       multipartner women rather than among the less active. Modification of
       the age mixing matrices has also a specific effect: the epidemic
       increases with the proportion of the youngest age group that has
       partners of the same age.
