目的：估计与未接受提醒的妇女相比，接受每日文本消息提醒的妇女是否增加了口服避孕药的依从性。方法：这项随机对照试验估计，每日文本消息提醒是否对口服避孕药的依从性有影响口服避孕药使用者。用无线数据收集的电子监控设备跟踪药丸的3个月。在研究期间，分配干预的参与者收到了每日提醒文本消息。将82名妇女随机分配，以检测1.6 +/- 2.0药丸差异（90％的功率，5％α，15％的辍学）。分辨率：参与者为79％的白人，非西班牙裔，99％的高中毕业生和99％ 99％的无效，平均年龄为22岁。大多数报道的避孕套与过去的固定活性一起使用，一半以上报告了事先紧急避孕的使用。两组之间的平均每个周期中丢失药丸的平均数量没有显着差异：文本 - 胶合组的4.9 +/- 3.0和对照组的4.6 +/- 3.5（p = .60）。在整个研究过程中，每个周期遗漏的药丸数量增加，但是两组之间的这种模式并没有差异。电子监控设备记录的依从性表明，依从性要比患者日记记录的依从性要差得多。尽管服用药丸不佳，但没有怀孕。判断：每日文字消息提醒并没有改善口服避孕药的依从性。尽管缺乏福利可能归因于对照组中经常使用替代提醒系统，但两组客观地测量的遗漏药的速率仍然很高。
OBJECTIVE: To estimate whether women receiving daily text-message reminders have increased oral contraceptive pill adherence compared with women not receiving reminders.METHODS: This randomized controlled trial estimated whether there was an effect of daily text-message reminders on oral contraceptive pill adherence of new oral contraceptive pill users. Pill-taking was tracked for 3 months by an electronic monitoring device with wireless data collection. During the study period, participants assigned the intervention received a daily reminder text message. Eighty-two women were assigned randomly to detect a 1.6 +/- 2.0 pill difference ( 90% power, 5% alpha, 15% dropout).RESULTS: Participants were 79% white, non-Hispanic, 99% high school graduates, and 99% nulliparous with a mean age of 22 years. Most reported condom use with past coital activity, and more than half reported prior emergency contraception use. The mean number of missed pills per cycle did not differ significantly between the groups: 4.9 +/- 3.0 for the text-message group and 4.6 +/- 3.5 for the control group (P = .60). The number of missed pills per cycle increased over the course of the study, but this pattern did not increase differentially between the groups. Adherence recorded by the electronic monitoring device indicated much poorer adherence than that recorded by patient diaries. Despite poor pill-taking, there were no pregnancies.CONCLUSION: Daily text-message reminders did not improve oral contraceptive pill adherence. Although the lack of benefit may be attributed to the frequent use of alternative reminder systems in the control group, the rate of missed pills when measured objectively was still very high in both groups.
