高龄产妇妊娠期尿路感染的危险因素分析及干预对策

目的探讨影响高龄产妇妊娠期尿路感染发生的危险因素，为临床防治提供依据和指导。方法选取2009年2月～2013年6月于我院就诊的195例高龄妊娠期产妇为研究对象。根据有无发生妊娠期尿路感染分为两组，其中31例发生妊娠期尿路感染者为观察组，164例未发生尿路感染者为对照组，分析高龄产妇妊娠期发生尿路感染的相关危险因素。结果高龄产妇发生妊娠期尿路感染的常见病原菌以大肠埃希菌（66．67％）为主，在高龄、大专以下受教育程度、个人尿路感染史、家族尿路感染史、妊娠期性生活史及贫血方面两组比较有统计学差异（P均〈0．05），在收入水平、经产状况和流产史等方面两组比较无统计学差异（P均〉0．05）；Logistic回归分析显示高龄、个人尿路感染史、家族尿路感染史、妊娠期性生活史和贫血是高龄产妇妊娠期发生尿路感染的独立危险因素（P均〈0．05）。结论高龄、个人尿路感染史、家族尿路感染史、妊娠期性生活史和贫血是高龄产妇妊娠期发生尿路感染的独立危险因素，常见病原菌以大肠埃希菌为主，应合理选用抗生素并对其相关危险因素进行干预加强防治。

nalysis on risk factors and intervention strategies for elderly maternity patients with urinarv tract infection in pregnancy

Objective To explore the risk factors of urinary tract infection in pregnancy for elderly maternity patients in order to provide the basis and guidance for clinical prevention and treatment. Methods One hundred and ninety- five elderly maternity patients in pregnancy admitted into our hospital from February 2009 to June 2013 were selected as the research objects, and divided into two groups according to with or without urinary tract infection in pregnancy, of which 31 cases with urinary tract infection in pregnancy were as the observation group, while 164 cases without urinary tract infection in pregnancy were as the control group. The correlative risk factors of urinary tract infection in pregnancy for elderly maternity patients were analyzed. Results The common pathogenic bacteria of urinary tract infection in pregnancy for elderly maternity patients were mainly Escherichia coli （66.67%）,and the differences were statistically significant in the elderly, under the junior college level, personal history, family history of urinary tract infections, sexual history in pregnancy and anaemia between the two groups（P all〈0.05）, while the differences were not statistically significant in income levels, parity and history of abortion between the two groups（P all〉0.05）; The logistic regression analysis showed that the elderly, personal history, family history of urinary tract infections, sexual history in pregnancy and anaemia were the independent risk factors for elderly maternity patients with urinary tract infection in pregnancy （P all〈0.05）. Conclusion The elderly, personal history, family history of urinary tract infections, sexual history in pregnancy and anaemia are the independent risk factors for elderly maternity patients with urinary tract infection in pregnancy, the common pathogenic bacteria are mainly Escherichia coli, and the use of antibiotics should be reasonable and the correlative risk factors should be intervened and enhanced to prevent and therapy.
