Pelvic inflammatory disease: a clinical syndrome with social causes

Prevalence of pelvic inflammatory disease (PID) reflects community and individual risk factors. Cultural and behavioural factors influence community prevalence of sexually transmitted disease (STD), illegal abortion, puerperal sepsis and contraceptive usage--all of which influence risk of PID. The relative importance of these factors will vary by region. Individual risk factors for the ascent of a lower genital tract infection are still poorly understood but are thought to be behavioural and immunological. Prevention of PID must be undertaken at several levels. At primary level, it requires a reduction in community risk. At secondary level, individual risk can be modified by ensuring diagnosis and treatment of STD before damage of the upper genital tract occurs. More attention to cultural factors should increase the potential for prevention at both levels.
