| Aim: Having several sexual partners is usually considered a potential risk for HIV contamination and other STI in heterosexual population. We defined two situations of multiple partnership: simultaneous, in which the individual had sexual relations with two or more partners during a same period of time; and serial in which the individual would start a new relationship only after finishing the former. Each situation is associated with a specific sexual behavior and thus with different level of exposure to HIV risk. The objective of our study was to characterize condom use in each of the situations. | ||||
| Method / Issue: Data were taken from the 2004 KABP AIDS survey, a household-based probability sample renewed every three years of the French noninstitutionalized population aged 18 to 69 that inquires their knowledge, attitudes, belief and practice facing HIV/AIDS threat. A new module in 2004 survey was addressed to respondents with more than two sexual partners over the past five years. It made it possible to collect detailed information on the respondents relations with their last two sexual partners. | ||||
| Results / Comments: Among respondents with two or more partners over the past five years (32.6% of men and 21.7% of women in the heterosexual sample), around one-fifth of men and 15.2% of women reported having simultaneous relations with their last two partners. For respectively one-fourth of these men and one-third of women, such relations had lasted longer than one year. Simultaneous partnership was much more frequent among respondents over 40 (especially men), in cohabitation for more than 5 years, better educated or socio-economically better positioned. Regarding condom use, both men and women in multiple partnership were more likely to have used condom during their last sexual intercourse. Thus, 9.6% of men with only one sexual partner reported condom use, 28.2% of those with two partners, 47% of men with three or four partners and 55.1% of those with 5 or more partners (respectively 10.1%, 19.4%, 31.1% and 36.0% among women). As hypothesised, among respondents with multiple partners, condom use during the first sexual intercourse with a new partner was also linked with the type of multiple partnership. 38.6% of men and 45.4% of women in simultaneous partnership reported condom use at first sex with their last partner (45.7% of men and 31.2% of women with their second last partner), far lower than those among respondents in serial relationship (respectively 75.7% of men and 72.3% of women with their last partner and 79.1% of men and 71.8% of women with their second last partner). Moreover, condom was much less systematically used along a simultaneous relationship than a serial relationship. | ||||
| Discussion: Condom use varies not only by the number of sexual partners but also by the type of multiple partnership. With a lower condom use level, the individuals in simultaneous relationship are exposed to a higher risk for HIV contamination. This subgroup of population needs therefore to be more specifically targeted during AIDS prevention campaigns. | ||||
