Typologies of Sexual Health Vulnerability Predicting STI Preventive Behaviors Among Latinx Adults in the U.S.: A Latent Class Analysis Approach.

Vulnerability to poor sexual health among U.S. Latinx populations is poorly understood, despite high STI rates. We examined how vulnerability typologies differ in their STI preventive behaviors. Using data from the 2016 National Health Interview Survey, we performed latent class analysis to test the association between sexual health vulnerability and HIV testing, hepatitis testing or vaccination, and HPV vaccination from a subsample of Latinx adults. Three classes emerged: Under-Employed Females with Health Care Access, Slightly Under-Employed Females with Some Health Care Access, and Employed Males without Health Care Access. Slightly Under-Employed Females with Some Health Care Access were associated with lack of HIV testing, hepatitis B and C testing, and HPV vaccination. Employed Males without Health Care Access were associated with lack of HIV testing and HPV vaccination. Sexual health vulnerability may be associated with certain STI preventive behaviors, which can inform and refine sexual health promotion programming.
