Understanding the psychosocial variables associated with sexual behavior is critical, particularly among high-risk individuals such as those who hook-up. It is possible body image is one of these variables. The current study aimed to examine the relationship between body appreciation and body image self-consciousness and three sexual health-related behaviors: 1) condom usage, 2) HIV screening, and 3) STI screening among a sample of adult men who have hooked up at least once in the past month (n = 243). We found that higher levels of body appreciation were related to being less likely to use condoms and higher levels of body image self-consciousness were related to being less likely to be screened for HIV and STIs. The conflicting results suggest additional research is warranted.
