Levonorgestrel emergency contraception (EC) is safe and effective for postcoital pregnancy prevention. Starting in 2013, the US Food and Drug Administration removed age restrictions, enabling EC to be sold over the counter to all consumers. We sought to compare the availability and access for female adolescents with the 2012 study, using the same study design.
Female mystery callers posing as 17-year-old adolescents in need of EC used standardized scripts to telephone 979 pharmacies in 5 US cities. Using 2015 estimated census data and the federal poverty level, we characterized income levels of pharmacy neighborhoods.
Of 979 pharmacies, 827 (83%) indicated that EC was available. This proportion did not vary by pharmacy neighborhood income level, nor was significantly different from the 2012 study ( = .78). When examining access, 8.3% of the pharmacies reported it was impossible to obtain EC under any circumstances, which occurred more often in low-income neighborhoods (10.3% vs 6.3%, adjusted odds ratio 1.5; 95% confidence interval 1.20-1.94). This was not significantly different from 2012 ( = .66). Correct information regarding over-the-counter access was conveyed only 51.6% of the time; accuracy did not differ by pharmacy's neighborhood income (47.9% vs 55.3%, adjusted odds ratio 0.89; 95% confidence interval 0.71-1.11) and was not significantly different from 2012 ( = .37).
A majority of pharmacies have EC available; however, barriers to and disparities in access for adolescents persist and have not changed since the previous study despite regulatory changes that were designed to improve access to EC.
左炔诺孕酮紧急避孕(EC)对于性交后预防妊娠安全有效。从2013年开始,美国食品药品监督管理局取消了年龄限制,使得EC能够面向所有消费者非处方销售。我们试图采用相同的研究设计,将女性青少年获取EC的情况与2012年的研究进行比较。
女性暗访者伪装成需要EC的17岁青少年,使用标准化脚本致电美国5个城市的979家药店。利用2015年的估计人口普查数据和联邦贫困线,我们对药店周边地区的收入水平进行了描述。
在979家药店中,827家(83%)表示有EC可供销售。这一比例不因药店周边地区的收入水平而有所不同,与2012年的研究结果也无显著差异(P = 0.78)。在考察获取情况时,8.3%的药店报告称在任何情况下都无法获得EC,这种情况在低收入社区更为常见(10.3%对6.3%,调整后的优势比为1.5;95%置信区间为1.20 - 1.94)。这与2012年的情况无显著差异(P = 0.66)。关于非处方获取的正确信息仅在51.6%的情况下得到传达;准确性不因药店周边地区的收入而有所不同(47.9%对55.3%,调整后的优势比为0.89;%置信区间为0.71 - 1.11),与2012年的情况也无显著差异(P = 0.37)。
大多数药店都有EC可供销售;然而,尽管有旨在改善EC获取情况的监管变化,但青少年获取EC的障碍和差异仍然存在,且自上次研究以来并未改变。
