上海市奉贤区气候因素与心力衰竭患者日急诊数量的相关性分析

Correlation Study Between Meteorological Factors and the Number of Daily Heart Failure Patients in Emergency Room at Fengxian District of Shanghai

目的:相关性分析上海市奉贤区气候因素与心力衰竭急诊抢救室患者数(以下代表急诊患者数)的关系,为预防和控制心力衰竭发病提供依据。方法:收集2012-01-01至2014-12-31上海市奉贤区中心医院急诊抢救室心力衰竭每日病例数,共355例,并采集同期气象和大气污染资料,进行Spearman相关分析及多元逐步回归分析。结果:(1)就诊前24 h、48 h及就诊后48 h的温度差、湿度差、气压差与心力衰竭日急诊数均呈正相关,与就诊前48 h温度差、气压差具有极显著相关性(P<0.001);(2)多元逐步回归分析显示最影响急性心力衰竭患者日急诊数的气候因素是日最低气温(P<0.05),其次是日平均相对湿度(P<0.05)。结论:气温、空气相对湿度和气压急变显著提高心力衰竭急诊患者数量;日最低气温、空气相对湿度的降低是增加心力衰竭急诊数的重要因素。

Objective：To analyze the relationship between meteorological factors and the number of daily heart failure（HF） patients for emergency room（ER） visit at Fengxian district of Shanghai in order to provide the experience for prevention and control of HF morbidity.Methods：Daily number of HF patients treated in ER of our hospital from 2012-01 to 2014-12 with corresponding meteorological,air pollution data at the same period were collected and analyzed by Spearman correlation study and multiple stepwise regression analysis.Results：1 The differences of temperature,humidity,air pressure at 24-,48-hour before and 48-hour after ER visit were positively related to the number of HF patients;the number of HF patients was significantly related to the differences of temperature and air pressure at 48-hour before ER visit,P〈0.001.2 Multiple stepwise regression analysis showed that the most affecting meteorological factor for ER visit of HF patients was the daily lowest temperature,P〈0.05,the second factor was the daily average relative humidity,P〈0.05.Conclusion：Radical changes of temperature,relative humidity and air pressure elevated the number of HF patients for ER visit;daily lowest temperature and decreased relative humidity were the important factors for elevating the number of HF patients for ER visit.
