Ryan Huerto, MD, MPH, MA; Tammy Chang, MD, MPH, MS; Marcus Spinelli da Silva


Upon completion of this poster session, learners should be able to describe trends in youth knowledge and perceptions regarding HIV and pre-exposure prophylaxis (PrEP). Learners should be able to describe the basic concepts of coding qualitative survey data. Learners should be able to apply results to future research questions and potential interventions for improving youth knowledge of HIV and proper utilization of PrEP.

Context: There are disparities in the incidence of HIV based on geographic location, race/ethnicity, gender, and sexuality. Pre-exposure prophylaxis (PrEP) is a daily medication that is highly effective at preventing HIV when taken consistently. Despite the prevalence of high-risk behaviors among youth, PrEP utilization remains low among this demographic. Data is limited in terms of youth’s knowledge and attitudes of HIV and PrEP.

Objective: To assess youth’s knowledge and attitudes regarding HIV and PrEP

Study Design: Survey and mixed methods study using the following questions:
1) This week we want to know what you would look for when choosing a doctor. What characteristics are important to you, if any? Why?
2) Is it important that you have similar characteristics to your doctor (age, gender, race/ethnicity, disability, background, personality, etc.)? If so, what characteristics?
3) When would being similar to your doctor be important? Specifically, for what type of healthcare visits?
4) How would being similar to your doctor impact what you say or do during your visit?
5) How would being similar to your doctor impact what you say or do during your visit?

Dataset: MyVoice, a national text message poll of youth aged 14-24 recruited via social media to meet benchmarks based on weighted samples of the American Community Survey

Population Studied: Diverse sample of youth (n = 1,164) representing every state in the U.S. with a response rate of 995/1,164 (85.5%)

Outcome Measures: Primary outcome is youth’s knowledge and attitudes regarding HIV and HIV prevention. Secondary outcome is young people’s knowledge, attitudes, and potential barriers to PrEP.

Anticipated Results: We hypothesize that PrEP knowledge will differ significantly based on socioeconomic status, education, race, region, and other demographic factors. Young people may be more likely to learn about PrEP through peers and internet/social media than from printed advertisements and healthcare providers.
