This 2-year, 28-day study examined whether adolescents felt greater fatigue and emotional distress the same day and the day after air quality was worse. We linked objective daily air quality measurements to daily self-reports from 422 Mexican-American adolescents in Los Angeles County, California from 2009 to 2011 (50% girls, M = 15 years). A robust, within-subject analysis of 9696 observations revealed that adolescents with ongoing physical complaints reported greater fatigue and emotional distress on days that the air contained higher levels of nitrogen dioxide (NO) and carbon monoxide (CO). Regardless of physical complaints, adolescents on average also reported greater fatigue the day after NO levels were higher. The same-day and next-day associations between air pollution and distress were mediated via daily increases in fatigue. Results were robust when controlling for day of the week, and daily temperature and humidity. Sulfur dioxide (SO), ozone (O), PM and PM were not related to daily fatigue or distress.
这项为期两年、28 天的研究旨在探究青少年在空气质量较差的当天及其后一天是否会感到更疲劳和情绪更困扰。我们将客观的每日空气质量测量值与 2009 年至 2011 年期间加利福尼亚州洛杉矶县 422 名墨西哥裔美国青少年（50%为女性，M=15 岁）的每日自我报告联系起来。对 9696 次观察的稳健的个体内分析显示，有持续身体不适的青少年在空气中二氧化氮 (NO) 和一氧化碳 (CO) 含量较高的日子里报告的疲劳感和情绪困扰更大。无论是否有身体不适，青少年在 NO 水平较高的次日平均也报告感到更疲劳。空气污染与困扰之间的当天和次日关联是通过每日疲劳感的增加来介导的。在控制了星期几、每日温度和湿度后，结果仍然稳健。二氧化硫 (SO)、臭氧 (O)、PM 和 PM 与每日疲劳或困扰无关。
