A prospective study of genital infections in a family-planning clinic. 2. Chlamydia infection--the identification of a high-risk group

Epidemiol Infect. 1990 Feb;104(1):55-61. doi: 10.1017/s0950268800054522.


During a study of genital infection in inner-city family-planning patients we examined 452 women for Chlamydia trachomatis. The prevalence of infection was 7.3%. There was no significant difference between patients attending because of genital symptoms and those who were attending for routine family-planning advice. Infection was found to be correlated with five main demographic parameters; age less than 25, no stable partnership, hormonal contraception, nulliparity and West Indian Ethnic origin. Using these parameters a simple scoring system was devised which allowed a high-risk population to be defined in whom screening would be economically justified.
