Introduction: According to WHO, no region in the world can justify a Cesarean rate higher than 10-15 percent. But unfortunately, Published statistics for most areas all over the world show a great difference with this ratio. Cesarean births pose greater risk to the mothers’ health, slow maternal recovery and increase relative mortality rate.

Objective: This study has been performed to determine the rate and related factors for Cesarean birth in Bojnurd.

Methods: This is a descriptive – analytic study and its samples consists of 473 mothers who gave birth to term, single Infants with birth weight & higher than 2500 gram. Type of delivery as independent variable and twenty other variables mainly relation to family socio-economic status and mother and infant characteristics as dependent variables were studied. Data needed was collected through direct observation and interview with mothers.

Results: The percentage of CS in Bojnurd was (25.4%) and rate of CS in cases such as better job and higher parental education (P<0.006), residency in city (P=0.001), less family numbers (P=0.008), birth weight of 3900 g or more (P=0.055), larger head circumference (P=0.01), increased weight of mother near delivery (P=0.13) and higher age of mother (P=0.054) were significantly increased.

Conclusion: Independent variables related to family Socio-economic status and also variables related to mother and infant such as mother’s age and weight near delivery which effects head circumference and birth weight had the most influencing on top of delivery. Rate of CS in mothers with better socio-economic conditions and also older mothers was significantly higher. Therefore, it seems that giving information to families and plans to lesser the age of marriage can decrease the rate of unnecessary, expensive and dangerous CS.
