This retrospectivestudy from Trakya University of Northwestern Turkey, describes antenatal factors involved inpreterm births at 26-32 weeks of pregnancy and compares with those involved in preterm births at 33-36 weeks.STUDY DESIGN: The records of preterm births at 26-32 weeks (earlier preterm births, n=419) and at33-36 weeks (later preterm births, n=158) during the years 2002-2010 were reviewed and the demographic,obstetric and medical features were evaluated retrospectively. The data was expressed as numbersand percentages and analyzed by SPSS 20.0.RESULTS: Iron supplementation [OR 0.27 (0.16-0.45), p=<0.001], short cervix [OR 9.12 (2.09-39.73)p=0.003] and infection [OR 2.6 (1.2-5.6) p=0.014] were important factors in the emergence of earlierpreterm births which occurred at the rate of 1.4%.CONCLUSIONS: Earlier preterm births at 26-32 weeks of pregnancy, which compose an obstetric issue,are associated with several antenatal risk factors such as nutrition, cervical problems and infections inNorthwestern Turkey.en10.201613/GORM.2016.695info:eu-repo/semantics/openAccessArticle24116385983
