To estimate the number of men in the U.S. military who are gay, bisexual, or other men who have sex with men (MSM) to inform the development of military and other federal policies.
We analyzed data from the National Surveys of Family Growth to estimate the number of U.S. men who were gay, bisexual, or MSM, and who had served in the military, compared to those who did not serve. We stratified using hierarchical categories of gay, bisexual, and other MSM to compare proportions in the military and general population.
We found that 4.23% of men self-reported as gay, bisexual, or other MSM among men who served in the military, compared to 4.14% among men who had not served (p = 0.93). When stratified, we found that 0.78% self-reported as gay among men who served in the military, compared to 2.12% among men who had not served (p<0.001).
The proportion of men who identified as a gay was lower in the military than in the general population. This finding might have been influenced by historical military policies related to sexual orientation.
估算美国军队中男同性恋者、双性恋者或其他与男性发生性行为者（MSM）的人数，以为军事及其他联邦政策的制定提供信息。
我们分析了全国家庭成长调查的数据，以估算曾在军队服役的男同性恋者、双性恋者或MSM的人数，并与未服役者进行比较。我们按男同性恋者、双性恋者和其他MSM的分层类别进行分层，以比较军队和普通人群中的比例。
我们发现，在曾服役的男性中，4.23%的男性自我报告为男同性恋者、双性恋者或其他MSM，而在未服役的男性中这一比例为4.14%（p = 0.93）。分层后，我们发现，在曾服役的男性中，0.78%的男性自我报告为同性恋，而在未服役的男性中这一比例为2.12%（p<0.001）。
军队中自我认定为同性恋的男性比例低于普通人群。这一发现可能受到了与性取向相关的历史军事政策的影响。
