Prevalence of sexual activity and outcome among female secondary school students in Port Harcourt, Nigeria.

Sexual activity among 534 Nigerian female secondary school students was studied using self-administered questionnaire. Prevalence of sexual intercourse was 25.7%. There was no significant difference between the junior (48.2%) and senior (51.8%) students (p > 0.05). Seventeen (12.4%) students had initiated sexual intercourse before 11 years. The frequency of sexual exposure was high, with 34.3% of the students having intercourse more than once in a week. Pregnancy rate among sexually active females was 27.0%, with 24.8% rate of induced abortion. Early sexual health education starting from primary school would be helpful in influencing the reproductive decisions and sexual behaviour of the students, including contraceptive acceptance and usage, to avoid teenage pregnancy. Education of parents is also recommended in order to overcome the cultural barriers that discourage parents from providing sex education to their children at home.
