Cesarean section (CS) rates in Tehran are alarmingly high at 72.0%. Risk factors include maternal age, socioeconomic status, and preeclampsia, necessitating interventions to reduce cesarean birth rates in Iran.
Area of Science:
- Obstetrics and Gynecology
- Public Health
- Epidemiology
Background:
- Global cesarean section (CS) rates have significantly increased.
- Iran exhibits a particularly high prevalence of CS.
- Understanding local risk factors is crucial for targeted interventions.
Purpose of the Study:
- To determine the prevalence of cesarean sections in Tehran.
- To identify associated risk factors for CS in the study population.
Main Methods:
- Cross-sectional study of 4,308 pregnant women in Tehran (July 2015).
- Multilevel logistic regression analysis incorporating demographic, obstetrical, and hospital-level variables.
- Analysis of factors influencing singleton live-births.
Main Results:
- The incidence of CS was 72.0%.
- Significant risk factors identified include maternal age, socioeconomic status, BMI, parity, pregnancy type, preeclampsia, infant height, and head circumference.
- Hospitals accounted for approximately 29.2% of the variation in CS rates (ICC=0.292).
Conclusions:
- The CS rate in Tehran is substantially higher than in many other countries.
- Educational and psychological interventions are recommended to lower CS rates among Iranian women.
- Addressing identified risk factors is essential for public health initiatives.

Multiple Regression
Farmers can use multiple regression to determine the crop yield based on more than one factor, such as water availability, fertilizer, soil properties, etc. Here, the crop yield is the response or dependent variable as it depends on the other independent variables. The analysis requires the construction of a scatter plot...
Correlation and Regression
Regression Analysis
In regression analysis, a regression equation is determined based on the line of best fit– a line that best fits the data points plotted in a graph. This line is also called the regression line. The algebraic equation for the regression line is called the regression equation. It is represented as:
