目的探讨沈阳市某社区医院儿科门诊量与空气质量及气象因素的关系。方法收集2012年1月1日—12月31日沈阳市某医院儿科门诊数据、空气质量指数(AQI)、大气污染级别以及气压、气温等气象监测数据,对上述资料的相关性和滞后效应进行分析,并构建回归方程进行预测。结果 2012年沈阳某医院儿科门诊量与气象指标中的平均气压、平均风速呈正相关,与降水量、平均水气压、平均气温、日最高气温、最低气温、平均相对湿度呈负相关;其中大气污染指数与女童呼吸系统疾病密切相关(P<0.01);AQI与当日和滞后1 d的呼吸系统门诊量有相关性(P<0.05);多因素回归分析显示呼吸系统门诊量与AQI呈正相关,与平均气压、平均相对湿度、最高气温呈负相关(P<0.05)。结论大气污染和气象因素是儿童呼吸系统疾病的重要影响因素。
Objective To investigate the relationship between pediatric outpatient volume and air quality and meteorological factors in a community hospital in Shenyang. Methods The data of pediatric outpatient, air quality index (AQI), air pollution level, air pressure and air temperature in a hospital in Shenyang from January 1, 2012 to December 31, 2012 were collected and analyzed for the correlation and lag effect of the above data Analysis, and build regression equation to predict. Results The outpatient volume of pediatrics in a hospital in Shenyang was positively correlated with mean air pressure and mean wind speed in a hospital in Shenyang in 2012, and was negatively correlated with precipitation, mean water pressure, mean temperature, daily maximum temperature, minimum temperature and mean relative humidity. Among them, air pollution (P <0.01). There was a significant correlation between the AQI and the respiratory outpatient service on the 1st and the 1th day (P <0.05). The multivariate regression analysis showed that the respiratory outpatient volume was positively correlated with the AQI, Average pressure, average relative humidity and maximum air temperature were negatively correlated (P <0.05). Conclusion Air pollution and meteorological factors are important influencing factors of children’s respiratory diseases.
