Aim. Chlamydia (C.) trachomatis infection is the most common sexually transmitted disease (STD) among sexually active adolescents and young adults in Europe. The aim of this study was to determine the prevalence of C. trachomatis among sexually active women in Piedmont, Italy and the correlation between some risk factors and C. trachomatis infection.
Methods. In our study 31419 sexually active women aged 12-55 were screened for C. trachomatis by Abbott's ligase chain reaction (LCR) using cervical swabs during the period 1997-2001 at St. Anna Obstetric-Gynecological Hospital, Turin. All the patients answered a specific questionnaire.
Results. In our analysis the prevalence of C. trachomatis infection was found to be 1.23%, and the average age among the infected patients was 36.98 years. Statistical analysis was performed using the x2 test; a p<0.05 was considered significant. A correlation was found between a positive test result and the age at the first intercourse (p<0.001), the number of sexual partners in the preceding 6 months (p<0.001), the presence of symptoms (p<0.001), a low level of education (p<0.001) and an East-European and Central-Northern African citizenship (p<0.001). No statistically significant differences were found among the contraceptive methods used, whether an hormonal or a barrier type; a marked increment of the risk was observed when no contraception was used.
Conclusion. Frequent microbiological examinations are desirable for patients whose anamnesis shows an augmented risk of contracting sexually transmitted infections in order to avoid long term complications from misdiagnosed or asymptomatic pathologies, as often happens with C. trachomatis.
