INTRODUCTION: Despite the knowledge that Chlamydia trachomatis is one of the most common sexually transmitted diseases, little is known in Portugal on the prevalence of this infection. Several sequelae can result from C. trachomatis in women, the most serious of which include PID, ectopic pregnancy, and infertility. Futhermore asymptomatic infections are common. Our aim in this study was to investigate the presence of Chlamydia trachomatis infection and associated factors among asymptomatic women in a Portuguese central hospital.

DESIGN AND METHODS: We prospectively studied all women aged 25 and under, who attend a medical consultation requesting contraceptive counseling and reported no urogenital symptoms. We investigated parameters like age, menarche, parity, age of sexual initiation, number of sexual partners and contraceptive use.  A urine sample was collected for polymerase chain reaction testing for Chlamydia trachomatis. Statistical analysis was carried out using Excel ®. Between-group differences were analyzed using the chi-square test and Student’s t-test.


RESULTS: We studied a total of 171 women. 55 were excluded for lack of information. Among the included women (n=116), the median age was 21 years. The average sexual life beginning was at 16 years and the number of sexual partners 3. About the parity, 84,25% were nulliparous. Half of them used oral contraceptives, 14,6 % barrier methods and only 7,8% no contraception. Chlamydia PCR test was positive in 19%. We found an association between positive test and >1 sexual partners (p= 0.0355) and early begin of sexual life (p=0,0008). There were no considerable differences between the various age groups (p=0,515) and the various contraceptive methods (p=0,328).


CONCLUSIONS: These results show the significant prevalence of Chlamydia trachomatis in Portugal. They also suggest the importance of targeting women who may worth screening, which is already done in some countries. Further study is need.
