Preexposure prophylaxis (PrEP) with a daily, oral pill containing antiretroviral drugs is highly effective in preventing acquisition of human immunodeficiency virus (HIV) infection (1-4). The combination of tenofovir disoproxil fumarate (TDF) and emtricitabine (FTC) is the only medication approved by the Food and Drug Administration (FDA) for PrEP. PrEP is indicated for men and women with sexual or injection drug use behaviors that increase their risk for acquiring HIV (5). CDC analyzed 2014-2016 data from the IQVIA Real World Data - Longitudinal Prescriptions (IQVIA database) to estimate the number of persons prescribed PrEP (users) in the United States and to describe their demographic characteristics, including sex and race/ethnicity. From 2014 to 2016, the annual number of PrEP users aged ≥16 years increased by 470%, from 13,748 to 78,360. In 2016, among 32,853 (41.9%) PrEP users for whom race/ethnicity data were available, 68.7% were white, 11.2% were African American or black (black), 13.1% were Hispanic, and 4.5% were Asian. Approximately 7% of the estimated 1.1 million persons who had indications for PrEP were prescribed PrEP in 2016, including 2.1% of women with PrEP indications (6). Although black men and women accounted for approximately 40% of persons with PrEP indications (6), this study found that nearly six times as many white men and women were prescribed PrEP as were black men and women. The findings of this study highlight gaps in effective PrEP implementation efforts in the United States.
暴露前预防(PrEP)是指每日口服抗逆转录病毒药物,可有效预防人类免疫缺陷病毒(HIV)感染(1-4)。富马酸替诺福韦二吡呋酯(TDF)和恩曲他滨(FTC)的组合是食品和药物管理局(FDA)唯一批准用于 PrEP 的药物。PrEP 适用于性行为或注射毒品使用行为增加 HIV 感染风险的男性和女性(5)。CDC 分析了 2014-2016 年 IQVIA 真实世界数据-纵向处方(IQVIA 数据库)中的数据,以估计美国接受 PrEP 处方(使用者)的人数,并描述他们的人口统计学特征,包括性别和种族/族裔。从 2014 年到 2016 年,年龄≥16 岁的 PrEP 使用者人数每年增加 470%,从 13748 人增加到 78360 人。2016 年,在可获得种族/族裔数据的 32853 名(41.9%)PrEP 使用者中,68.7%为白人,11.2%为非裔美国人或黑人(黑人),13.1%为西班牙裔,4.5%为亚洲人。2016 年,大约有 110 万有 PrEP 指征的人中,有 7%被开了 PrEP 处方,其中有 PrEP 指征的女性中有 2.1%(6)。尽管黑人男性和女性约占有 PrEP 指征的人群的 40%(6),但本研究发现,被开 PrEP 处方的白人男性和女性人数几乎是黑人男性和女性的六倍。这项研究的结果突出了美国在有效实施 PrEP 方面的差距。
