Objective:

To analyze the prevalence of modern contraceptive methods (CM) use in adolescents aged 12 to 19 years in 2012 and 2018-19, and the factors associated with consistent use of modern CM.

Materials and methods:

Using the Health and Nutrition National Surveys 2012 and 2018-19 we calculated the outcome variables: long-acting reversible contraceptives (LARC) use, dual protection and consistent use of CM. We estimated prevalence by sex and adjusted logistic models with consistent use (which is understood as CM use in the first and last sexual relationship) as a dependent variable.

Results:

LARC use in last intercourse increased between surveys (4.1 to 6.3%). For women, being older, not having been pregnant, and school attendance increased the likelihood of consistent use. For men, school attendance increases the likelihood while cohabiting, early sexual initiation and having smoked more than 100 cigarettes reduces it.

Conclusion:

It is necessary to promote access and consistent use of MC, based on respect for sexual and reproductive rights.
