Evolution of contraceptive methods usage among women aged 15-49: comparative analysis between regions of Northern Argentina, 2011-2012 and 2019-2020

Abstract

Introduction: Access to modern contraceptive methods constitutes a key determinant in sexual and reproductive health, particularly in regions with socioeconomic inequalities. In Argentina, several public policies have sought to guarantee this access, especially in the northern regions of the country.

Objective: To analyze variations in the use of contraceptive methods among women aged 15-49 years in Argentina, with emphasis on the NOA and NEA regions during 2011-2012 and 2019-2020, examining their distribution according to socioeconomic strata.

Materials and methods: Quantitative, cross-sectional descriptive study. Data from the National Multiple Indicator Cluster Surveys (MICS) 2011-2012 (n=20844) and 2019-2020 (n=11763) were analyzed. Comparative prevalence analysis was performed with 95% confidence intervals. Results: A significant increase in the use of contraceptive methods was observed in Argentina (57.69% to 61.33%) and NOA (43.78% to 57.46%) between 2011-2012 and 2019-2020. Subdermal implants showed the greatest increase in adolescents in the NOA (0% to 35.24%) and NEA (0% to 32.59%). In the poorest quintiles, contraceptive use increased significantly, especially in the NEA (31.04% to 52.30%).

Conclusion: The increase in the use of modern contraceptive methods, particularly in vulnerable populations of Northern Argentina, suggests a positive impact of the implemented public policies, especially the ENIA Plan, in improving access to contraception.
