About this study
Official title: Sexual Behavior and Risk Perception as Factors Associated With the Incidence of Sexually Transmitted Infections (STIs) in Young Adults Aged 18-25 Years
This observational cross-sectional study aims to assess sexual behavior and perception of sexual risk among young adults aged 18 to 25 years in Barcelona, Spain, and to examine their association with self-reported sexually transmitted infections (STIs). The study will also explore knowledge and beliefs about STIs, protective practices such as condom use, number of sexual partners, and experiences of sexual pressure or coercion. The study will use a validated scale to assess perception of risk related to sexual behavior, together with an additional questionnaire developed for the study population.
Read the detailed description
Sexually transmitted infections (STIs) are an important public health concern among young people. Although young adults may have access to information about STI prevention, this knowledge does not always translate into protective sexual practices.
This observational cross-sectional study will investigate the relationship between sexual behavior, perception of sexual risk, and self-reported STI occurrence among young adults aged 18 to 25 years living in or attending educational institutions in Barcelona, Spain.
Participants will complete an anonymous questionnaire including sociodemographic characteristics, sexual behavior, knowledge and beliefs about STIs, perception of sexual risk, protective practices such as condom use, and number of sexual partners. The questionnaire will also include questions concerning experiences of sexual pressure or coercion and other forms of sexual or digital control. Perception of sexual risk will be assessed using a previously validated scale, complemented by study-specific questions.
The study will describe patterns of sexual behavior and risk perception and will examine whether lower perceived sexual risk is associated with riskier sexual behaviors and a higher prevalence of self-reported STIs.

What is being measured
The primary outcome is the main question the study is designed to answer.

Secondary outcomes (4)
Self-reported diagnosis of a sexually transmitted infection in the past 12 months
Proportion of participants who report having been diagnosed with a sexually transmitted infection during the previous 12 months, based on the question: "Have you been diagnosed with a sexually transmitted infection in the past 12 months?" Responses will be recorded as yes or no.
Measured: At study enrollment
