[Sexual behaviour among adolescents in Brazzaville, Congo].
OBJECTIVE
Estimate sexual activity among Congolese adolescents in Brazzaville and appreciate the influence of sociocultural and economic factors on sexual behaviour.


METHODS
Data were collected from 900 adolescents (389 males and 511 females) aged 10-19 years in the seven urban areas of Brazzaville. These subjects were randomly recruited by a two stage sampling. The data were gathered by an anonymous face-to-face questionnaire. Relative risk estimations were calculated for early or first sexual intercourse, multiple sexual partnerness and safe sex.


RESULTS
A total of 474 respondents indicated that they were sexually active. Females were more sexually active, 270 compared with 204 males (p<0.05). The mean early age of coital debut was 14.6 years (S.D.=1.7 years). Early intercourse (before 14 years) was found in 73 males and 39 females (p<0.001). Multiple sexual partnerness was found in 81.3% of males, while the frequency of females was 51.1%. Risk factors for pregnancy and multiple sexual partnerness were unemployment mother, non school situation, early puberty and non sexual education. In contrast, regular religious activity was recognized as factor that had significant protection impact on sexual activity. The total use ratio of the condom was estimated at 42.2% in males. More females (41.7%) were using Ogino method of contraception. In addition, 102 females (36.8%) claimed to have already a pregnancy and the mean age was 16.1 years (S.D.=1.2 years). In 64.7% of these cases, teenagers chose the abortion as solution of an unwanted pregnancy. After the birth of a child, it was reported that 82.4% of adolescents gave up with school.
