Prevalence and type of contraception use among US college students: A needed update.

backgroundWhile rates of unintended pregnancy are declining among adolescents and young adults in the United States (US), rates remain higher than other industrialized nations and are associated with both educational and economic challenges. Studies examining young adult contraceptive practices are dated and limited in scope. Understanding current contraceptive use of young adults is critical to ensure intentional pregnancies.

methodsWe used the American College Health Association-National College Health Assessment III 2022-2023 national dataset to examine contraceptive use patterns among 30,568 sexually active 18- to 24-year-old college students at 4-year institutions. Differences based on students' biological sex, race/ethnicity, year in school and number of sexual partners in the last 12 months were examined. Prevalence estimates with confidence intervals were calculated; chi-square tests were used to assess initial bivariate differences and t-tests were used to determine significant pairwise comparisons. Bonferroni correction set the significance level to p<.001219.

resultsMost sexually active college students were using contraception (87.6%); however, there were significant differences among students based on demographic characteristics. Black, Latinx, and multiracial students and students with more than one sexual partner in the last 12 months were less likely to use contraception (ps < 0.001). There were also differences in the types of single and dual contraceptive methods used among students based on demographics. Significant differences based on race/ethnicity occurred across all methods and combinations of methods. Results indicated less consistent patterns of differences for sex, year in school, and number of sexual partners for single and dual use.

conclusionsThis study provides a critical update on contraceptive use among US college students. The findings indicate which subgroups may be more at risk for an unintended pregnancy due to lower overall contraceptive use and use of methods that are less effective. Differences in race/ethnicity regarding contraceptive use continue to exist, and students with fewer years of education emerged as another essential group deserving attention. Improved awareness of methods and access to birth control are potential strategies to increase uptake. College health professionals and other clinical providers who work with US college students can use these findings to inform discussions with students who may need additional information about all available options.
