Introduction:

In Peru, 78.1% of women between the ages of 15 and 49 use a contraceptive method, which is diminished by various factors associated with non-adherence to the contraceptive method, thus producing unwanted pregnancies and the spread of sexually transmitted diseases.

Objective:

To determine the factors associated with non-adherence to contraceptive methods in women of childbearing age in Peru according to ENDES 2021.

Methods:

The population of this research is made up of peruvian women between the ages of 15 and 49. Statistical analysis was performed with the statistical program SPSS version 26.0. The qualitative variables were represented in a univariate table with frequencies and coefficients of variation. The approved statistical significance value was p <0.05 with 95% confidence intervals.

Results:

43.7% of women did not adhere to the contraceptive method. There was a significant association for the variables: area of rural residence (RPa 1.05 IC 1 - 1.1), separated marital status (RPa 1.1, IC 1 - 1.1), widow marital status (RPa 1.3, IC 1.1 - 1.5), cohabiting marital status (RPa 1.1, IC 1.1 - 1.2) , poor wealth index (RPa 1.03, IC 0.9 - 1.0)
