BACKGROUND
Preconception care, including family planning, is a vital component of healthcare for women of reproductive age. An average female spends the majority of her reproductive life trying to prevent a pregnancy. In order to prevent unintended pregnancy, women often rely on the use of hormonal contraceptives. In the United States, the majority of hormonal contraceptive users are prescribed oral contraceptive pills (OCPs). Reduced adherence to OCPs decreases their ability to prevent pregnancy. The study aimed to measure OCP adherence among female college students, and explore the relationship between OCP adherence, knowledge, and self-efficacy.
METHODS
This cross-sectional study recruited a random sample of female college students to participate in an online survey. OCP adherence was based on the 8-item Morisky Medication Adherence Scale (MMAS-8). Secondary reporting of medication adherence included participant reports of the number of missed OCP doses in the previous month and typical month of use.
RESULTS
Of the 5000 invited, 1559 (31.3%) completed the survey. Of those responding, 670 (41.3%) reported use of OCPs. A total of 293 (44.3%) OCP users met criteria for low adherence, 241 (36.4%) met criteria for medium adherence, and 128 (19.3%) met criteria for high adherence. Those with high adherence had higher self-efficacy (P < 0.001) and perceived knowledge (p < 0.001). After controlling for other factors, self-efficacy (b = .37) and perceived knowledge (b = .09) remained associated with OCP adherence.
CONCLUSION
Less than 20% of respondents met the criteria for high adherence to OCPs. Self-efficacy and knowledge were associated with higher OCP adherence. Targeted interventions from healthcare providers, health educators, and other adherence related media to increase the knowledge and self-efficacy of patients using OCPs may improve adherence rates. Additional research is needed to evaluate the impact of innovative interventions focused on social and behavioral patient factors, like knowledge and self-efficacy, on adherence to OCPs.
背景
孕前保健，包括计划生育，是育龄妇女医疗保健的重要组成部分。一般来说，女性在其大部分生殖期都在努力避免怀孕。为了防止意外怀孕，女性通常依赖于使用激素避孕药。在美国，大多数激素避孕药使用者都开口服避孕药（OCPs）。OCP 依从性降低会降低其避孕能力。本研究旨在衡量女大学生的 OCP 依从性，并探讨 OCP 依从性、知识和自我效能之间的关系。
方法
本横断面研究招募了随机样本的女大学生参与在线调查。OCP 依从性基于 8 项 Morisky 药物依从性量表（MMAS-8）。次要报告的药物依从性包括参与者报告的上个月和典型月份错过的 OCP 剂量数。
结果
在邀请的 5000 人中，有 1559 人（31.3%）完成了调查。在做出回应的人中，有 670 人（41.3%）报告使用了 OCP。共有 293 名（44.3%）OCP 使用者符合低依从性标准，241 名（36.4%）符合中等依从性标准，128 名（19.3%）符合高依从性标准。具有高依从性的人具有更高的自我效能（P < 0.001）和感知知识（p < 0.001）。在控制其他因素后，自我效能（b =.37）和感知知识（b =.09）仍与 OCP 依从性相关。
结论
不到 20%的受访者符合 OCP 高依从性标准。自我效能和知识与更高的 OCP 依从性相关。来自医疗保健提供者、健康教育者和其他与依从性相关的媒体的有针对性的干预措施，以增加使用 OCP 的患者的知识和自我效能，可能会提高依从率。需要进一步研究评估针对 OCP 依从性的创新干预措施，重点关注社会和行为患者因素，如知识和自我效能。
