醫(yī)學(xué)論文范文:香港與北京市嚴(yán)重急性呼吸道綜合征綜合流行因素
【摘要】 目的:評價(jià)香港與北京市嚴(yán)重急性呼吸道綜合征(SARS流行相關(guān)綜合因素。方法:采用因子分析方法對香港與北京市SARS流行的相關(guān)因素進(jìn)行提取公因子,再對這些復(fù)合變量進(jìn)行構(gòu)筑式多元回歸與Logistic回歸分析。評估這些復(fù)合變量對香港及北京市SARS流行的影響。結(jié)果:香港SARS流行因素因子分析提取出3個(gè)公因子(措施時(shí)間因子、日發(fā)病數(shù)因子和院內(nèi)感染倍增因子;隨著日發(fā)病數(shù)因子的增加,香港特區(qū)暴發(fā)SARS的危險(xiǎn)性約增大35.3倍。北京市SARS流行因素因子分析也提取出3個(gè)公因子(院內(nèi)感染倍增因子、措施時(shí)間因子和住_出院因子;隨著院內(nèi)感染倍增因子的增加,北京市暴發(fā)SARS的危險(xiǎn)性增加39.4倍。結(jié)論:影響SARS流行的重要因素可能是干預(yù)措施與時(shí)間因素,造成SARS暴發(fā)流行的主要原因是SARS傳染源數(shù)量劇增。

[Abstract]Objective:To evaluate the multiple factors involved in SARS epidemic between Hong Kong and Beijing. Methods:A principal component analysis on the potential factors was used to search for principal components. Then, the analyses of multiphase regression and Logistic regression on these components were applied. Results: In Hong Kong, Measure_Time Factor,Daily Case Factor and Hospital Infection Factor involved in SARS epidemic were gained. The estimated risk of a larger SARS epidemic in Hong Kong was 35.3_fold higher with increase of Daily Case Factor. Hospital Infection Factor, Measure_Time Factor and Hospitalization_Discharge Factor involved in SARS epidemic in Beijing also were obtained. The estimated risk of a larger SARS epidemic in Beijing was 39.4_fold higher with increase of Hospital Infection Factor. Conclusion:Intervention measure and epidemic time may be the most important factors involved in SARS epidemic. The infection source of SARS increased sharply might result in a larger SARS epidemic醫(yī).學(xué)全.在.線網(wǎng)站gydjdsj.org.cn.

嚴(yán)重急性呼吸道綜合征(SARS2002_11首先在中國廣東暴發(fā),2003_02傳入香港。2003_03_01北京發(fā)現(xiàn)第1例輸入性SARS病例,隨后蔓延到周邊國家和地區(qū)[1_2]。SARS的傳染性極強(qiáng),病死率高,傳播速度快,對公眾健康構(gòu)成嚴(yán)重威脅。因此,研究SARS流行的相關(guān)因素具有重要的醫(yī)學(xué)意義和社會(huì)價(jià)值。SARS暴發(fā)以來,研究其流行相關(guān)因素的論文很多,但大多只考慮單獨(dú)因素(如預(yù)防措施對SARS流行的影響[3]。本研究綜合考慮多個(gè)因素(每日新發(fā)病例、干預(yù)措施、醫(yī)院感染、流行時(shí)間等對SARS流行的作用,采用因子分析方法,將多個(gè)自變量組合成復(fù)合變量,探索這些綜合因素對SARS流行的影響。
