Medical records were reviewed.<jats:italic>Result.<\/jats:italic>Among 243 with major placenta praevia, 56 (23.0%) were primigravidas and 187 (77.0%) were nonprimigravidas. Factors associated with placenta praevia in the primigravidas were history of assisted conception (<mml:math xmlns:mml=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M1\"><mml:mi>P<\/mml:mi><mml:mo>=<\/mml:mo><mml:mn>0.02<\/mml:mn><\/mml:math>) and history of endometriosis (<mml:math xmlns:mml=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M2\"><mml:mi>P<\/mml:mi><mml:mo>=<\/mml:mo><mml:mn>0.01<\/mml:mn><\/mml:math>). For maternal outcomes, the nonprimigravidas required earlier delivery than primigravidas (35.76 \u00b1 2.54 weeks versus 36.52 \u00b1 1.95 weeks,<mml:math xmlns:mml=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M3\"><mml:mi>P<\/mml:mi><mml:mo>=<\/mml:mo><mml:mn>0.03<\/mml:mn><\/mml:math>) and had greater blood loss (<mml:math xmlns:mml=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M4\"><mml:mi>P<\/mml:mi><mml:mo>=<\/mml:mo><mml:mn>0.04<\/mml:mn><\/mml:math>). A vast majority of the primigravidas had either posterior type II or type III placenta praevia. As for neonatal outcomes, the Apgar score at 1 minute was significantly lower for the nonprimigravidas (7.89 \u00b1 1.72 versus 8.39 \u00b1 1.288.39 \u00b1 1.28,<mml:math xmlns:mml=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M5\"><mml:mi>P<\/mml:mi><mml:mo>=<\/mml:mo><mml:mn>0.02<\/mml:mn><\/mml:math>).<jats:italic>Conclusion.<\/jats:italic>This study highlighted that endometriosis and assisted conception were highly associated with placenta praevia in primigravida. Understanding the pregnancy outcomes of women with placenta praevia can assist clinicians in identifying patients who are at higher risk of mortality and morbidity. Identifying potential risk factors in primigravida may assist in counseling and management of such patients.<\/jats:p>","DOI":"10.1155\/2014\/270120","type":"journal-article","created":{"date-parts":[[2014,11,12]],"date-time":"2014-11-12T16:01:35Z","timestamp":1415808095000},"page":"1-6","source":"Crossref","is-referenced-by-count":7,"title":["Factors
