In univariate analysis, higher maternal age, parents’ educational level, economic status, body mass index, fetal head circumference, preeclampsia, and use of assisted reproductive technology were associated with Cesarean section. Moreover, multivariate analysis showed a significant relationship between Cesarean section with mother’s age, economic status, and body mass index and also with fetal head circumference. Conclusion: The prevalence of Cesarean section is very high in Tehran province. Factors such as mother’s age, socioeconomic status, and body mass index, and fetal head circumference were related to Cesarean section.
