Introduction: Iran experienced a dramatic fertility decline during recent decades.
There was also an indication of a shift towards later childbearing from 2000. Past
research on fertility has shown that the education variable is the most important
determinant of fertility behaviors. However, the impact of education on fertility timing
in Iran has been less considered.
Methods: In a cross sectional study 1149 ever-married women aged 35-44 in three
provinces with different levels of fertility, Semnan, Hormozgan, Kohkiluye and Booir
Ahmad, were selected by the multi-stage cluster sampling method. A structured
questionnaire instrument was used for data collection. Kaplan-Meier estimates and
Cox Regression were used to analyze data.
Results: Kaplan-Meier estimates in three province show significantly different
between age at first birth and women’s educational level (P<0.05). Mean of age at first
birth among university educated women in Semnan, Hormozgan, and Kohkiloye and
Booir Ahmad provinces was 23.5, 24.6 and 24.29 respectively. Results of the
multivariate analysis using the Cox Proportional Hazard model show also that
university education is a significant factor in reducing the risk a first birth in three
provinces. However the decreasing impact on the risk of first birth in Semnan is lower
than other provinces.
Conclusion: Women’s access to education in Iran is a substantial contributor of
postponement of childbearing and higher educated women are pioneers in delaying
childbearing and reducing fertility in Iran.
