The prevalence of sexually transmitted disease (STD), pelvic inflammatory disease (PID), and cervical cancer, and the relation between these conditions were studied in 2111 Ethiopian women. Early sexual activity was associated with an increase in prevalence rates of STD and PID; possible aetiological factors include physical and immunological immaturity of the female genital tract and the number of sexual partners.
