Insights
Genital chlamydia trachomatis infection is prevalent in young pregnant women, with a 13.7% infection rate observed in women aged 20 and under. Young age is the primary risk factor, supporting universal screening for pregnant women up to age 25.
Area of Science:
- Reproductive Health
- Infectious Diseases
- Obstetrics & Gynecology
Background:
- Genital Chlamydia trachomatis infections in pregnancy are linked to adverse outcomes like premature rupture of membranes, postpartum endometritis, and neonatal conjunctivitis/pneumonitis.
- Identifying risk factors for chlamydial infection during pregnancy can inform targeted screening strategies.
- Currently, no national screening strategy exists for genital Chlamydia trachomatis in pregnant populations.
Purpose of the Study:
- To determine the prevalence of genital Chlamydia trachomatis infection in pregnant women aged 20 years or younger.
- To identify associated risk factors for chlamydial infection in this demographic.
- To provide evidence supporting updated chlamydia screening recommendations in pregnancy.
Main Methods:
- A retrospective review of medical records was conducted for young women (≤20 years) attending antenatal care.
- Screening for C. trachomatis was routinely offered and data on demographics and sexual history were extracted.
- The study period spanned from January 2003 to June 2006 at RPA Women and Babies Young Parents Clinic.
Main Results:
- Of 365 eligible pregnant women, 212 were screened for genital C. trachomatis.
- A significant infection rate of 13.7% was identified in this cohort.
- Young maternal age was identified as the most critical risk factor for infection.
Conclusions:
- The high prevalence (13.7%) of chlamydia infection in pregnant women aged 20 and under underscores the need for targeted screening.
- Young maternal age is the predominant risk factor for genital chlamydia infection during pregnancy.
- These findings support recommendations for universal screening of pregnant women up to 25 years of age for C. trachomatis.
Introduction:
Detection and treatment of genital chlamydia trachomatis infections in pregnancy have been shown to reduce the risk of premature rupture of membranes, and post-partum endometritis and reduce the risk to the newborn of conjunctivitis and pneumonitis. Identification of factors associated with chlamydial infection in pregnancy could be used to develop criteria for routine chlamydia screening for some pregnant women. No national screening strategy exists around genital Chlamydia trachomatis infection.
Methods:
We undertook a review of the medical records of all young women (aged 20 years or younger) attending the RPA Women and Babies Young Parents Clinic for antenatal care between January 2003 and June 2006. This group was chosen as RPA Women and Babies routinely offers testing for C. trachomatis to women attending the Young Parents Clinic. Data extracted included age, country of birth, language spoken at home, postcode of usual residence, marital status, educational level, change of sexual partners within the past 12 months, consistency of condom use and history of sexually transmissible infections.
Results:
Two hundred and twelve of the 365 eligible pregnant women were screened for genital C. trachomatis, of whom 29 were positive. A rate of 13.7% genital chlamydia infection was found in this population of young pregnant women.
Conclusions:
Results from this study indicate that the rate of chlamydia infection (13.7%) is high in women aged 20 years or younger and that the most important risk factor is young age. These findings support recent recommendations that all women 25 years and younger are screened for C. trachomatis in pregnancy.
