In 2016, the US Food and Drug Administration changed the regulation from a permanent deferral from donation for men who have sex with men (MSM) to a 1-year deferral since last sexual contact. It is unknown what proportions of MSM try to donate and if they would be willing to answer individual risk-based questions to assess their current eligibility.
The National HIV Behavioral Surveillance surveys periodically measure human immunodeficiency virus (HIV) prevalence and risk behaviors among MSM using a venue-based, time-location sampling method. In the 2014 cycle, that is, before the policy change, investigators in San Francisco and New Orleans added questions about blood donation. Questions inquired into three domains: donation history, policy awareness, and knowledge about HIV testing of donations.
There were 404 and 557 respondents in San Francisco and New Orleans, respectively. Nearly one in three MSM in San Francisco (27.4%) and New Orleans (31.4%) tried to donate after their first MSM contact. A majority (63.1% in San Francisco, 58.8% in New Orleans) somewhat or strongly agreed that they would be willing to be asked detailed questions for donation eligibility assessment.
The proportion of MSM who reported trying to donate was similar in the two cities. However, a substantial proportion did not agree to be asked more detailed risk behavior questions to assess eligibility. In these two geographic locations, prominent regional differences were not evident.
2016年，美国食品药品监督管理局将针对男男性行为者（MSM）的献血规定从永久性延期献血改为自最后一次性接触起延期1年。尚不清楚有多大比例的男男性行为者尝试献血，以及他们是否愿意回答基于个体风险的问题以评估其当前的献血资格。
全国艾滋病毒行为监测调查采用基于场所的时间 - 地点抽样方法，定期测量男男性行为者中的人类免疫缺陷病毒（HIV）流行率和风险行为。在2014年周期，即政策变更之前，旧金山和新奥尔良的研究人员增加了关于献血的问题。问题涉及三个领域：献血历史、政策知晓度以及对献血HIV检测的了解。
旧金山和新奥尔良分别有404名和557名受访者。在旧金山，近三分之一的男男性行为者（27.4%）以及在新奥尔良（31.4%）在首次男男性行为接触后尝试献血。大多数人（旧金山为63.1%，新奥尔良为58.8%） somewhat或强烈同意他们愿意被询问详细问题以进行献血资格评估。
两个城市中报告尝试献血的男男性行为者比例相似。然而，相当大比例的人不同意被询问更详细的风险行为问题以评估资格。在这两个地理位置，明显的地区差异并不明显。 （注：原文中“somewhat”翻译为“ somewhat”是因为不确定具体准确意思，可能是“有点”之类的意思，需结合更完整语境判断）
