The potential health risks for communities that surround railyards have largely been understudied. Mastery and quality of life (QoL) have been associated with self-reported health status in the general population, but few studies have explored this variable among highly vulnerable low-income groups exposed to harmful air pollutants. This study investigates the relationship between self-reported health status and correlates of Heart Disease Risk Factors (HDRF) and Respiratory Illness (RI) with mastery and QoL acting as potential protective buffers. This cross-sectional study of 684 residents residing near a Southern California railyard attempts to address this limitation. Results from three separate hierarchal linear regressions showed that those who reported being diagnosed with at least one type of HDRF and/or RI reported lower perceived health status. For those that lived further from the railyard, mastery and QoL predicted modest increases in perceived health status. Results suggest that mastery and QoL may be helpful as tools in developing interventions but should not solely be used to assess risk and health outcomes as perceived health status may not measure actual health status.
铁路附近社区的潜在健康风险在很大程度上还没有得到充分研究。在一般人群中，掌握程度和生活质量（QoL）与自我报告的健康状况有关，但很少有研究探讨在接触有害空气污染物的高度脆弱的低收入群体中这一变量。本研究调查了自我报告的健康状况与心脏病风险因素（HDRF）和呼吸道疾病（RI）之间的关系，掌握程度和 QoL 作为潜在的保护缓冲因素。这项对居住在南加州一个铁路附近的 684 名居民的横断面研究试图解决这一局限性。三项独立的层次线性回归结果表明，那些报告被诊断出至少有一种 HDRF 和/或 RI 的人报告的健康状况较差。对于那些住在离铁路更远的人来说，掌握程度和 QoL 预测他们的健康状况会适度改善。结果表明，掌握程度和 QoL 可以作为开发干预措施的有用工具，但不应仅仅用于评估风险和健康结果，因为自我报告的健康状况可能无法衡量实际的健康状况。
