VILLALOBOS, Aremis; CASTRO, Filipa de; ROJAS, Rosalba  and  ALLEN, Betania. Contraception in Mexican adolescents in upper secondary schools: use and unmet needs. Salud pública Méx [online]. 2017, vol.59, n.5, pp.566-576. ISSN 0036-3634.


To describe sexual behavior and contraceptive use in adolescent students.

Materials and methods:

National representative survey in upper secondary schools in Mexico 2014. Logistic regressions identify the factors associated with contraceptive use and unmet needs for contraception (UNC).


For male adolescents, non-contraceptive use in the last sexual relation is associated with non-contraceptive use in the sexual debut (OR=11.5; IC95%:5.6,23.4) and not recognizing effective contraceptive methods (OR=2.4;IC95%:1.04,5.5). For female adolescents, non-contraceptive use is associated with non-contraceptive use in sexual debut (OR=4.5;IC95%:2.3,8.4) and low self-efficacy towards condom use and negotiation (OR=3.1; IC95%:1.1,8.2). UNC were associated with insecure attitudes towards condom use and negotiation (OR=3.5;IC95%:1.3,9.4), non-contraceptive use in sexual debut (OR=9.0;IC95%:2.5,32.4) and use of alcohol or drugs during sexual relations (OR=3.0;IC95%:1.1,8.1).


Strategies to ensure contraceptive use from sexual debut onwards are required, promoting self-efficacy and safe sex practices among adolescents.
