Correlates of sexually transmitted infection knowledge among late adolescents.

Background Accurate knowledge about sexually transmitted infections (STIs) is imperative for young people's development and sexual health outcomes, but STI knowledge has been found to be inadequate among youth. Little is known about the factors that are associated with STI knowledge. This study therefore comprehensively assessed correlates of STI knowledge among late adolescents. Methods: Undergraduate students (n = 419) at a large public Midwestern university completed an online survey that assessed general STI knowledge using an established modified scale, demographics, sexual health and behavioural factors, and sources of STI information. Exploratory bivariate analyses were first conducted followed by a multiple linear regression examining the correlates initially identified as significantly and strongly associated with STI knowledge. Results: Although many factors were significantly correlated with STI knowledge, gender, nationality, sexual identity, STI testing history, knowing someone diagnosed with an STI, prior school-based STI education, and receiving STI information from a healthcare provider were most strongly associated (P < 0.001 with medium or large effect sizes). All but prior school-based STI education were predictive of STI knowledge score (P = 0.103), with nationality (β = 0.172, P = 0.003) and gender (β = 0.147, P = 0.002) being the strongest predictors. Conclusions: Late adolescents' STI knowledge was universally low, but disparities existed and were related to a variety of characteristics. These findings expand the current literature on young people's STI knowledge and provide needed information to prioritise populations and methods for educational interventions in order to enhance STI knowledge among youth.
