We describe the sample, design, and procedures for the Community and Surrounding Areas Study (CASAS), an ancillary to the Hispanic Community Health Study/Study of Latinos (HCHS/SOL). The aim of SOL CASAS was to test an ecological model of macro- and micro-neighborhood environment factors, intermediate behavioral (physical activity) and psychosocial (e.g., depression and stress) mechanisms, and changes in cardiometabolic health in Hispanics/Latinos.
Between 2015 and 2017, approximately 6 years after the HCHS/SOL baseline (2008-2011), 1776 San Diego HCHS/SOL participants enrolled in SOL CASAS and completed a repeat physical activity assessment. Participants' residential addresses were geoprocessed, and macroenvironmental features of the home were derived from publicly available data concurrent with the HCHS/SOL baseline and Visit 2 (2014-2017). Microscale environmental attributes were coded for 943 unique routes for 1684 participants, with a validated observational tool, concurrent with Visit 2, for SOL CASAS participants only.
Of 2520 HCHS/SOL participants approached, 70.5% enrolled (mean age 55.3 years; 94% Mexican; 67.5% female). Accelerometer adherence (three or more days with at least 10 hours wear time) was outstanding (94%).
With its more comprehensive ecological model and well-characterized Hispanic/Latino population, SOL CASAS will advance the science concerning the contribution of neighborhood factors to cardiometabolic health.
我们描述了社区及周边地区研究（CASAS）的样本、设计和程序，该研究是西班牙裔美国人社区健康研究/拉丁裔研究（HCHS/SOL）的一个辅助研究。SOL CASAS 的目的是测试宏观和微观邻里环境因素、中间行为（身体活动）和心理社会因素（如抑郁和压力）以及西班牙裔/拉丁裔人群中心血管代谢健康变化的生态模型。
在 2015 年至 2017 年间，即 HCHS/SOL 基线（2008-2011 年）后约 6 年，1776 名圣地亚哥 HCHS/SOL 参与者参加了 SOL CASAS，并完成了重复的身体活动评估。参与者的居住地址经过地理处理，家庭的宏观环境特征来自与 HCHS/SOL 基线和访问 2（2014-2017 年）同期的公开数据。微观环境属性是为 1684 名参与者的 943 条独特路线编码的，仅针对 SOL CASAS 参与者，使用了经过验证的观察工具，与访问 2 同期进行。
在 2520 名被邀请的 HCHS/SOL 参与者中，有 70.5%（平均年龄 55.3 岁；94%为墨西哥裔；67.5%为女性）入组。加速度计的佩戴依从性（至少佩戴三天且每天佩戴至少 10 小时）非常好（94%）。
SOL CASAS 具有更全面的生态模型和特征明确的西班牙裔/拉丁裔人群，将推进关于邻里因素对心血管代谢健康贡献的科学研究。
