[Survey on sexual behavior by Congolese and French high-school students in an AIDS context]

The social and economic impact of AIDS add to those of a recent civil war in 1997. There were fratricidal confrontations before and after this period. Pointe-Noire, the second city of Congo and the economic Capital, was on the whole spared. We carried out a survey of 292 high-school students: 39% of girls and 61% of boys, from 14 old to 25 years old (average age of 19 years). They were from 5 general and technical schools, which are representative of the school recruitment of the city of Pointe-Noire. This study made in 1998 was the second part of a work achieved in France in 1997 with 1,859 high-school students: 70% of girls and 30% of boys, mean age 17.7 years, range 15-25 years. They came from 3 general, technical and professional schools of two departments of the region "Centre" ("Indre-et-Loire" and "Loir-et-Cher"). The material, corresponding to this study, is an anonymous self-questionnaire of 55 closed items presented in the form of assertions to which the student respond either yes or no. Items investigated: 1) pubertal maturation and subjective maturation; 2) different aspects of sexual experience in adolescence (components of sexual experience) [9] and 3) sexual behaviour (including sexual risk taking). All items have been formulated in the most accessible possible way for the youngsters. Previously, in 1996, we had made a pre-test with this material near sample of French people from 16 to 68 years old. The results of the study highlight that the Congolese youngsters present more risk than their French homologues. Although the pubertal status (the menarche and the spermarche) occurs slightly later, Congolese boys present a greater number of sexual partners and greater sexual precocity. Among 54% of Congolese pupils from the sample which had already had a sexual intercourse (68% of boys and 42% of girls) versus 52% of French pupils (58% of boys and 49% of girls), 88% of the Congolese boys have sexual intercourse at the age of 15, versus 72% of the girls at 16.5 versus 65% of the French boys in their 15.5 and 52% of the girls at 16. These differences are significant (p < 0.001) like all the following ones. Congolese students declare more sexual partners (4 during the last 12 months and 5 for all their life versus 3.2 and 4.4 for the French students); the boys more than the girls (6.5 sexual partners on the whole versus 3.7 for the girls in Congo and 5.7 versus 3.8 in France). Congolese girls generally have fewer sexual relations (over 12 months or during their entire life) than French high-school girls (respectively 5.9, 6.9 versus 8.7 and 9.3). We can see with French and Congolese students, a "traditional" dichotomy between boys and girls: that is to say girls tend to engage later in sexual relations and to favour the long and regular relations, while the boys have more short, and spaced sentimental relations. The relations of these last ones tend to evolve on a more preparatory mode, genital and intermittent, contrary to those girls who seem more sentimental and continuous. The use of the condom concerns 72% of the French pupils for the first sexual intercourse (74% of boys versus 72% of girls) - which is close to results of French reference surveys [1, 3]. On the other hand, they are only 39% to make use of it in Congo in this circumstance (36% of the boys and 34% of the girls). All Congolese young people present more STD (6% versus 4% for the French pupils) and more pregnancy (11% versus 3%). The other risky situations appear also more important in Congo: as the fact of having sexual intercourse after having drunk too much (6% of case where it arrives systematically versus 2% in France); to have sexual intercourse with a injecting drug user (4% versus 1%); paying or to have been paid (in a systematic way 7% versus 1%). The Congolese answers concerning the recourse to prostitution are more dissimilar and alarming concerning Congolese young people, especially if one takes into account all the situations where it occurred at least once (29% of the boys and 13% of the Congolese girls who declare to have had a sexual intercourse by paying (with money). Homosexual relations are more frequent in Congo (4 and 6% versus 2 and 3% for France). Homosexual experience concerned 13% of the Congolese pupils versus less than 5% of the French ones. The answers concerning a sexual partner who is "not sure" (20% in Congo versus 2% in France) can get clearer in the Congolese context with an elevated prevalence rate of infection by HIV. However, other cultural factors should not be neglected. The same applies for the answers relative to the sexual intercourse under duress (29% for Congo versus less than 7% in France). The answers relative to the fact of having a sexual intercourse with a much older partner (21% versus 13%) do not seem surprising for Congo. But it does not free risks. All these elements are not associated with a better estimate of the personal risk. (ABSTRACT TRUNCATED)
