Air pollution has become a significant public health concern. During exercise, many physiological factors are thought to increase the effects of air pollution. Air pollution most affects lung function and respiratory symptoms. We investigated the association between lung function, respiratory symptoms, and air pollutant concentration with meteorological factors in elite sports athletes.
A total of 59 elite sports athletes from the Korea National Sports University participated in this prospective, observational study from September 2019 to June 2020. At ten visits, lung function and respiratory symptoms were obtained after a training session. We measured six air pollutants, including SO, CO, O, NO, PM, and PM, and two meteorological factors, including humidity and temperature. Air pollutants and meteorological factors were measured by two nearest depositories of the national air pollution information system in Korea.
In a single-pollutant model, PM, PM, NO, and CO were inversely associated with both FEV and FEV, 10 μg/m in PM was associated with a 32.31 mL decrease in FEV and a 36.93 mL decrease in FEV. Meanwhile, O and temperature had positive associations with both FEV (13.00 and 3.15 mL) and FEV (16.91 and 4.76 mL) and humidity with FEV (11.98 mL). In the multi-pollutant model at lag 0, FEV was associated negatively with O and NO (-50.68 and -6.87 mL) and positively with SO and temperature (65.76 and 8.08 mL). In the multi-pollutant model at lag 6, temperature was associated with FEV and FEV (6.01 and 8.89 mL). PM, PM, NO, CO, and temperature were significantly associated with FEV and FEV through lag 0-6.
Air pollutants and meteorological factors are associated with lung function and respiratory symptoms and have cumulative effects among elite athletes. In the multi-pollutant model, temperature has the most significant effect on lung function.
空气污染已成为重大公共卫生问题。运动时，许多生理因素被认为会增加空气污染的影响。空气污染对肺功能和呼吸道症状的影响最大。我们研究了精英运动员的肺功能、呼吸道症状与空气污染物浓度以及气象因素之间的关系。
2019 年 9 月至 2020 年 6 月，来自韩国国立体育大学的 59 名精英运动员参加了这项前瞻性观察研究。在 10 次访问中，运动员在训练后获得肺功能和呼吸道症状数据。我们测量了六种空气污染物，包括 SO、CO、O、NO、PM 和 PM，以及两个气象因素，包括湿度和温度。空气污染物和气象因素由韩国国家空气污染信息系统的两个最近的储存库测量。
在单污染物模型中，PM、PM、NO 和 CO 与 FEV 和 FEV 呈负相关，PM 每增加 10μg/m，FEV 下降 32.31mL，FEV 下降 36.93mL。同时，O 和温度与 FEV（分别为 13.00 和 3.15mL）和 FEV（分别为 16.91 和 4.76mL）呈正相关，湿度与 FEV 呈正相关（11.98mL）。在滞后 0 时的多污染物模型中，FEV 与 O 和 NO 呈负相关（分别为-50.68 和-6.87mL），与 SO 和温度呈正相关（分别为 65.76 和 8.08mL）。在滞后 6 时的多污染物模型中，温度与 FEV 和 FEV 呈正相关（分别为 6.01 和 8.89mL）。PM、PM、NO、CO 和温度通过滞后 0-6 与 FEV 和 FEV 显著相关。
空气污染物和气象因素与精英运动员的肺功能和呼吸道症状有关，并具有累积效应。在多污染物模型中，温度对肺功能的影响最大。
