Objectives
Sexually transmitted infections (STIs) lead to female reproductive morbidity, are frequently asymptomatic, and rates continue to rise. Adolescents are known to be at high risk for STIs and have higher rates of chlamydia trachomatis (CT) compared with adults. Studies from the UK and Australia suggest that adolescents show higher prevalence of CT at presentation to colposcopy. Our primary objective was to investigate the rate of CT at first presentation to colposcopy in adolescents (<=25yo) compared with adults (>25yo) and to determine whether universal STI screening for adolescents is warranted at this visit. The secondary objective was to investigate associations between demographic and behavioral characteristics and incident STIs.
Methods
We conducted a retrospective cohort study of new patients who presented for colposcopy at an inner-city clinic from January 2011 to December 2013. The charts of 761 adults and 245 adolescents were evaluated. We performed a univariate analysis with a chi-squared test to investigate the associations between age group and established variables.
