Dyadic Data from Four Studies of MSM: 2009-2013 [United States; Atlanta, GA]

The dataset contains harmonized variables from four studies of men who have sex with men (MSM) conducted at Emory University from 2009-2013. The variables include the age and race/ethnicity of participants and their recent male sexual partners. The objective of the analysis was to examine racial differences in age mixing, including whether age mixing was related to prevalent HIV infection.<br><br>Two of the four studies were Internet-based samples in the US. The two other studies sampled MSM in the Atlanta area, of which one used a mixture of online and offline recruitment methods and the other used offline methods exclusively. For all studies, participants were eligible if they were male at birth, aged 18 years or older, and had a male sex partner within a specified period prior to enrollment in the study. In order to examine differences in age mixing between Black and White MSM, we restricted our analytic samples to those who reported being Black or White and not Hispanic. All studies were reviewed and approved by the Emory University Institutional Review Board.<br>

本数据集包含埃默里大学（Emory University）2009年至2013年间开展的4项男男性行为者（men who have sex with men, MSM）研究的经标准化整合的变量。这些变量涵盖研究对象及其近期男性性伴侣的年龄与种族/族裔信息。本次分析旨在探究年龄配对模式中的种族差异，包括年龄配对是否与现症HIV感染相关。

4项研究中有2项为美国本土的互联网招募样本。其余2项研究以亚特兰大地区的男男性行为者为招募对象：其中1项同时采用线上与线下招募方式，另1项仅使用线下招募手段。所有研究的纳入标准均为：出生性别为男性、年龄满18周岁，且在研究入组前的特定期限内拥有男性性伴侣。为探究黑人与白人男男性行为者之间的年龄配对差异，本研究将分析样本限定为自我报告为非西班牙裔黑人和白人的研究对象。所有研究均已通过埃默里大学机构审查委员会（Institutional Review Board）的伦理审查与批准。
