Objective To describe the community context of women who travel to access Mexico City’s public sector abortion programme and identify factors associated with travelling from highly marginalised settings. Methods We used data from the Interrupción Legal de Embarazo (ILE) programme (2016–2019) and identified all abortion clients who travelled from outside Mexico City. We merged in contextual information at the municipality level and used descriptive statistics to describe ILE clients’ individual characteristics and municipalities on several measures of vulnerability. We also compared municipalities that ILE clients travelled from with those where no one travelled from. We used logistic regression to identify factors associated with travelling to access ILE services from highly marginalised versus less marginalised municipalities. Results Our sample included 21 629 ILE clients who travelled to Mexico City from 491 municipalities within all 31 states outside Mexico City. The majority of clients travelled from the least marginalised (81.9%) and most populated (over 100 000 inhabitants; 91.3%) municipalities. Most (91.2%) ILE clients came from municipalities with adolescent fertility rates in the bottom three quintiles. Clients with a primary or secondary education (vs high school or more) and those from a municipality with a high adolescent fertility rate (top two quintiles) had higher odds of travelling from a highly marginalised (vs less) municipality (adjusted odds ratio (aOR) 1.46, 95% CI 1.35 to 1.58 and aOR 1.89, 95% CI 1.68 to 2.12, respectively). Conclusion ILE clients travel from geographically and socioeconomically diverse communities. There is an unmet need for legal abortion across Mexico. Data are available in a public, open access repository. All data used in this study are publicly available and details on the sources are provided in Supplemental Table 1.

2016-2019 年墨西哥堕胎服务旅行：墨西哥城公共堕胎客户的社区层面背景

目的 描述前往墨西哥城公共部门堕胎计划的妇女的社区背景，并确定与来自高度边缘化环境的旅行相关的因素。方法 我们使用来自 Interrupción Legal de Embarazo (ILE) 计划（2016-2019 年）的数据，并确定了从墨西哥城以外旅行的所有堕胎客户。我们合并了市级的上下文信息，并使用描述性统计数据来描述 ILE 客户的个人特征和市政府对几个脆弱性的衡量标准。我们还比较了 ILE 客户从哪里来的城市和没有人从哪里来的城市。我们使用逻辑回归来确定与从高度边缘化和边缘化程度较低的城市获取 ILE 服务相关的因素。结果 我们的样本包括来自墨西哥城以外所有 31 个州的 491 个城市的 21 629 名 ILE 客户。大多数客户来自边缘化程度最低（81.9%）和人口最多（超过 10 万居民；91.3%）的城市。大多数 (91.2%) ILE 客户来自青少年生育率处于倒数三分之二的城市。受过小学或中学教育（相对于高中或以上）的客户以及来自青少年生育率高的城市（前两个五分之一）的客户从高度边缘化（相对于较少）城市旅行的几率更高（调整优势比（aOR ) 1.46, 95% CI 1.35 至 1.58 和 aOR 1.89, 95% CI 1.68 至 2.12)。结论 ILE 客户来自地理和社会经济多元化的社区。墨西哥各地对合法堕胎的需求未得到满足。数据可在公共、开放访问的存储库中获得。本研究中使用的所有数据都是公开的，补充表 1 中提供了有关来源的详细信息。
