For each case, 8 women who delivered during the same month and had no infection after SBC induction were selected for control. &lt;b&gt;&lt;i&gt;Results:&lt;\/i&gt;&lt;\/b&gt; Compared with the control group, the IAI group had a higher rate of nulliparity (87.93 vs. 70.69%; &lt;i&gt;p&lt;\/i&gt; = 0.006), BMI &amp;#x3e; 30 kg\/m&lt;sup&gt;2&lt;\/sup&gt; (29.31 vs. 15.95%; &lt;i&gt;p&lt;\/i&gt; = 0.011), and amniotic fluid index (AFI) &amp;#x3c; 8 cm (32.8 vs. 15.1%; &lt;i&gt;p&lt;\/i&gt; = 0.001). The diameter of cervical dilatation when membranes ruptured in IAI group was smaller than that in the control group (2.0 [1.5] vs. 3.0 [8.0] cm; &lt;i&gt;p&lt;\/i&gt; &amp;#x3c; 0.001). Time from start of induction to vaginal delivery was longer than that in the control group (47.0 [19.75] vs. 27.0 [16.0] h; &lt;i&gt;p&lt;\/i&gt; &amp;#x3c; 0.001). After logistic regression, the 5 factors associated with IAI for those who underwent SBC induction were nulliparity, BMI &amp;#x3e; 30 kg\/m&lt;sup&gt;2&lt;\/sup&gt;, AFI &amp;#x3c; 8 cm, diameter of cervical dilatation &amp;#x3c; 3 cm when membranes ruptured and time from start of induction to vaginal delivery of more than 48 h. &lt;b&gt;&lt;i&gt;Conclusions:&lt;\/i&gt;&lt;\/b&gt; Focus on these risk factors could result in earlier prophylaxis so that the incidence of IAI  could be reduced.<\/jats:p>","DOI":"10.1159\/000493795","type":"journal-article","created":{"date-parts":[[2018,10,17]],"date-time":"2018-10-17T21:02:53Z","timestamp":1539810173000},"page":"183-189","source":"Crossref","is-referenced-by-count":3,"title":["Risk Factors of Intra-Amniotic Infection Related to Induction with Single-Balloon Catheter: A Case-Control Study"],"prefix":"10.1159","volume":"84","author":[{"given":"Yongqing","family":"Zhang","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ying","family":"Yu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Luping","family":"Chen","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wei","family":"Zhao","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ketan","family":"Chu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiujun","family":"Han","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2018,10,17]]},"container-title":["Gynecologic and Obstetric Investigation"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/493795","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/493795","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,23]],"date-time":"2025-04-23T16:56:37Z","timestamp":1745427397000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000493795"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2018,10,17]]},"references-count":0,"journal-issue":{"issue":"2","published-online":{"date-parts":[[2019,3,20]]},"published-print":{"date-parts":[[2019,3,26]]}},"URL":"https:\/\/doi.org\/10.1159\/000493795","archive":["Portico"],"relation":{},"ISSN":["0378-7346","1423-002X"],"issn-type":[{"type":"print","value":"0378-7346"},{"type":"electronic","value":"1423-002X"}],"subject":[],"published":{"date-parts":[[2018,10,17]]}}}
