To date, no studies utilizing global positioning system (GPS) technologies to measure mobility and environmental exposures have been conducted among a sample of transgender women despite the potential salient role neighborhood contexts may play in the health of this population. As such, the purpose of this study was to assess the acceptability and feasibility of a weeklong GPS protocol among a sample of transgender women in New York City. A sample of 14 transgender women residing in the New York City metropolitan area were recruited through community based methods to wear and charge a GPS device for 7 days to measure daily mobility. The acceptability of these methods was assessed using a pre- and postprotocol survey and their feasibility was measured using objective data derived from the GPS device. Pre- and postprotocol survey measures were compared using McNemar's test. Participants reported high ratings of preprotocol acceptability, as well as few concerns regarding safety, appearance, and losing the device, all of which were maintained after completing the protocol. All 14 devices that were distributed were returned. In addition, all 14 participants had GPS data for at least 1 h on 1 day, and nine participants (64.3%) had at least 8 h of GPS data on all days. The findings of this pilot study demonstrate that the GPS methods are both acceptable and feasible among this sample of transgender women. GPS devices may be used in research among transgender women to understand neighborhood determinants of HIV and other STIs.
迄今为止，尽管邻里环境可能对这一人群的健康具有重要作用，但尚未对跨性别女性样本开展利用全球定位系统（GPS）技术来测量其流动性和环境暴露情况的研究。因此，本研究的目的是评估在纽约市的跨性别女性样本中进行为期一周的GPS方案的可接受性和可行性。通过社区招募的方式，选取了14名居住在纽约市大都市区的跨性别女性，让她们佩戴并充电GPS设备7天，以测量日常活动情况。使用方案实施前后的调查问卷评估这些方法的可接受性，并使用从GPS设备获得的客观数据来衡量其可行性。使用麦克尼马尔检验比较方案实施前后的调查问卷测量结果。参与者对方案实施前的可接受性评价很高，并且对安全、外观和丢失设备等方面几乎没有担忧，在完成方案后这些情况都保持不变。分发的所有14台设备都被归还。此外，所有14名参与者在某一天至少有1小时的GPS数据，9名参与者（64.3%）在所有日子里至少有8小时的GPS数据。这项初步研究的结果表明，GPS方法在这个跨性别女性样本中既具有可接受性又具有可行性。GPS设备可用于跨性别女性的研究，以了解艾滋病毒和其他性传播感染的邻里决定因素。
