Emerging adults face a disproportionate burden of unintended pregnancies and sexually transmitted diseases, especially in the southern United States. This study investigates how multiple dimensions of current religiosity as well as religious upbringing influence the sexual behaviors, including contraceptive usage, of individuals 18-25 years old (n=211) in the South. Based on regression analyses, results suggest that emerging adults with higher levels of current religiosity are more likely to remain abstinent, but less likely to use pregnancy prevention methods, such as birth controls pills and long-acting reversible contraceptives. Having a religious upbringing is also associated with lower contraceptive usage. Through the assessment of multiple dimensions of religiosity and various sexual behaviors, this study presents a nuanced picture of the complex associations between religion and sexual health, specifically among emerging adults in the southern United States.
