Introduction:

The World Health Organization considers postpartum family planning as the main intervention that saves the lives of mothers and children, because, by favoring intergenetic periods of two or more years, it reduces infant and maternal mortality by 10% and 30%, respectively.

Objective:

Women of reproductive age were studied during the months of May and June of 2018, at a health center in Mexico City. 136 women participated who had up to a maximum of eleven months and 29 days after an obstetric event. An anonymous self-application questionnaire was prepared, consisting of 21 questions. The information was integrated into the program SPSS version 25, and analyzed through descriptive and inferential statistics.

Results:

A significant correlation was found between the use of contraceptive methods after an obstetric event and the variables knowledge of the couple regarding the use of the contraceptive method (P<0.000), schooling of the patient (P<0.020), area of ​​the health center in which counseling was received (P<0.032), and number of monthly sexual relations (P<0.038).
