地方是至关重要的，我们了解人类免疫缺陷病毒（HIV）感染的男性之间发生性关系的男人（MSM）在美国。然而，在科学文献中，地点几乎总是由居住地点表示，这表明居住区、风险地点和预防地点之间的基本假设是等同的。然而，MSM的行为的位置显示出显着的空间差异，和理论已经假定的重要性，非住宅环境暴露。这种对居住地点的关注至少部分是由于难以收集探索非居住地点所需的详细地理定位数据。本研究使用网路地图工具搜集可能与男男性接触者日常生活与健康行为相关的地点，并检验资料的完整性与可靠性。MSM在网上招募，并完成了基于网络的调查。在这项调查中，男性使用嵌入在问题中的地图工具来指示他们的家和多个非住宅位置，包括代表工作，性别，社交，医生等的位置。我们通过检查数据的完整性和可靠性来评估数据质量。我们使用逻辑回归来确定回答所有符合条件的地图问题和回答特定地图问题的人口统计学，上下文和特定位置的预测因素。我们通过将选定的地点与其他参与者报告的数据进行比较来评估数据的可靠性。在完成调查的247名男性中，有167人（67.6%）回答了所有符合条件的地图问题。大多数参与者（>80%）回答了具体的地图问题，性地点是最少的报告（80.6%）。没有受过大学教育的参与者比受过大学教育的参与者更不可能回答所有地图问题（患病率，0.4; 95% CI，0.2-0.8）。在伴侣家中报告性行为的参与者不太可能指出该性别的位置（患病率比，0.8; 95%CI，0.7-1.0）。总体而言，83%的参与者将他们家的位置放在他们报告的住宅邮政编码范围内。在具有特定文本描述的位置中，参与者选择的位置与使用特定文本描述确定的位置之间的中值距离为0.29英里（第25和第75次搜索，0.06-0.88）。使用这个基于网络的地图工具，这个基于网络的MSM样本一般愿意并能够提供关于家庭和非住宅位置的准确数据。该工具提供了一种收集数据的机制，可用于对MSM的场所和性风险以及预防行为进行更细致入微的研究。
Place is critical to our understanding of human immunodeficiency virus (HIV) infections among men who have sex with men (MSM) in the United States. However, within the scientific literature, place is almost always represented by residential location, suggesting a fundamental assumption of equivalency between neighborhood of residence, place of risk, and place of prevention. However, the locations of behaviors among MSM show significant spatial variation, and theory has posited the importance of nonresidential contextual exposures. This focus on residential locations has been at least partially necessitated by the difficulties in collecting detailed geolocated data required to explore nonresidential locations. Using a Web-based map tool to collect locations, which may be relevant to the daily lives and health behaviors of MSM, this study examines the completeness and reliability of the collected data. MSM were recruited on the Web and completed a Web-based survey. Within this survey, men used a map tool embedded within a question to indicate their homes and multiple nonresidential locations, including those representing work, sex, socialization, physician, and others. We assessed data quality by examining data completeness and reliability. We used logistic regression to identify demographic, contextual, and location-specific predictors of answering all eligible map questions and answering specific map questions. We assessed data reliability by comparing selected locations with other participant-reported data. Of 247 men completing the survey, 167 (67.6%) answered the entire set of eligible map questions. Most participants (>80%) answered specific map questions, with sex locations being the least reported (80.6%). Participants with no college education were less likely than those with a college education to answer all map questions (prevalence ratio, 0.4; 95% CI, 0.2-0.8). Participants who reported sex at their partner’s home were less likely to indicate the location of that sex (prevalence ratio, 0.8; 95% CI, 0.7-1.0). Overall, 83% of participants placed their home’s location within the boundaries of their reported residential ZIP code. Of locations having a specific text description, the median distance between the participant-selected location and the location determined using the specific text description was 0.29 miles (25th and 75th percentiles, 0.06-0.88). Using this Web-based map tool, this Web-based sample of MSM was generally willing and able to provide accurate data regarding both home and nonresidential locations. This tool provides a mechanism to collect data that can be used in more nuanced studies of place and sexual risk and preventive behaviors of MSM.
