Objective To assess LARC use trends among college women (18-24 years) and identify groups that have increased LARC use. Methods Data were extracted from the National College Health Assessment-II (NCHA-II) fall 2008-2013 surveys. Logistic regression statistics were used to assess LARC use. Results Although LARC use increased from 2008 to 2013 (aOR = 2.62; 95% CI 2.23-3.07), less than half of the sample (44%) reported using contraception at last vaginal sex. Only 2.5% of college women in this study reported using a LARC method; of LARC users, 90% reported using an intrauterine device. Nearly all sociodemographic factors were significantly associated with increases in LARC use including: age, sexual orientation, and insurance status. Conclusions LARC use significantly increased among college women. However, less effective methods such as condoms and short-acting reversible contraceptives are used more frequently. Promoting LARC use for women who desire to effectively prevent pregnancy can reduce unintended pregnancy and improve health outcomes for women while in college. Future work should examine the importance of individual and lifestyle factors that influence college women's decision to choose a LARC method and seek to eliminate barriers to college women choosing a contraceptive method they believe works best for them.
目的 评估18 - 24岁大学女性长效可逆避孕法（LARC）的使用趋势，并确定使用LARC人数增加的群体。方法 数据取自2008 - 2013年秋季全国大学健康评估-II（NCHA-II）调查。采用逻辑回归统计方法评估LARC的使用情况。结果 尽管2008年至2013年LARC的使用有所增加（调整后比值比[aOR]=2.62；95%置信区间[CI]为2.23 - 3.07），但样本中不到一半（44%）的人报告在最后一次性交时使用了避孕措施。在本研究中，只有2.5%的大学女性报告使用了LARC方法；在使用LARC的人群中，90%报告使用宫内节育器。几乎所有社会人口学因素都与LARC使用的增加显著相关，包括年龄、性取向和保险状况。结论 大学女性中LARC的使用显著增加。然而，避孕套和短效可逆避孕药等效果较差的方法使用更为频繁。对于希望有效预防怀孕的女性推广使用LARC，可以减少意外怀孕并改善大学期间女性的健康状况。未来的工作应研究影响大学女性选择LARC方法的个人和生活方式因素的重要性，并设法消除大学女性选择她们认为最适合自己的避孕方法的障碍。
