Background: Smoking during pregnancy is one of the manageable causes of preterm births compared with high smoking rate in developed countries, the scenario in China is different to some extent. Methods: We carried out a population-based epidemiological study of 115,311 women from 14 urban cities in China. Maternal parameters were evaluated on their first obstetric visit; smoking rate was analyzed by one-way analysis of variance with Bonferroni correction and 2 tests. Results: Among the 115,311 women, 0.28% (314) women were smokers during pregnancy, while 0.92% (1,037) women had prenatal alcohol exposure. Odds ratio for preterm birth was 0.66 (P=0.12) for smokers and 0.72 (P=0.05) for women with alcohol consumption, respectively. Smoking and alcohol exposure were not significantly related with preterm birth. Conclusion: Despite the reported threefold increase of preterm birth with ten cigarettes a day, smoking and alcohol exposure are currently not the most significant risk factors for preterm birth in China.
