Asymptomatic bacteriuria (ASB) is defined as the presence of bacteria in urine without having signs and symptoms. The aim of this meta-analysis was to estimate the overall prevalence of asymptomatic bacteriuria among Iranian pregnant women.
Major national and international databases were searched up to November 2015, including Scientific Information Database, MagIran, Web of Science, Medline, Scopus, Science Direct and Ovid. The checklist of the STROBE statement was used for evaluating the quality of reporting. The extracted data were analyzed and the results were reported using a random-effects model with 95% confidence interval (CI).
From 3709 obtained studies, 20 included in the meta-analysis, which involved 15108 pregnant women. The overall prevalence of ASB was 0.13 (95% CI: 0.09, 0.17). The prevalence of ASB in the northern and southern regions of Iran was 0.13 (95% CI: 0.09, 0.18) and 0.11 (95% CI: 0.05, 0.16), respectively.
Prevalence of ASB among Iranian pregnant women is considerable. Due to the complications of ASB for pregnant women and their children, preventative planning and control of ASB among pregnant women in Iran is necessary.
无症状菌尿（ASB）被定义为尿液中存在细菌但无体征和症状。本荟萃分析的目的是估计伊朗孕妇中无症状菌尿的总体患病率。
检索截至2015年11月的主要国家和国际数据库，包括科学信息数据库、MagIran、科学网、医学索引、Scopus、科学直投和Ovid。采用STROBE声明清单评估报告质量。对提取的数据进行分析，并使用95%置信区间（CI）的随机效应模型报告结果。
从3709项获得的研究中，20项纳入荟萃分析，涉及15108名孕妇。无症状菌尿的总体患病率为0.13（95%CI：0.09，0.17）。伊朗北部和南部地区无症状菌尿的患病率分别为0.13（95%CI：0.09，0.18）和0.11（95%CI：0.05，0.16）。
伊朗孕妇中无症状菌尿的患病率相当高。由于无症状菌尿对孕妇及其子女会产生并发症，因此有必要在伊朗对孕妇进行预防性规划和无症状菌尿的控制。
