This age group is vulnerable to obstetric complications, including lacerations of the anal sphincter.</p> <p><strong>Objective:</strong> To determine the prevalence of third and fourth degree perineal tears in adolescents during childbirth, and to evaluate risk factors in comparison with deliveries with lacerations of adult women. Methods: All obstetric care episodes were reviewed from a public tertiary hospital data in Monterrey, Mexico in 2014. Age, primiparity, delivery instrumentation, episiotomy, body mass index, product weight and tear´s degree were documented at the deliveries with tears of third and fourth degree.</p> <p><strong>Results:</strong> The prevalence of third and fourth degree tears of 2.0% was found in the general population, being adolescents the most affected with 2.5%. The unadjusted odds ratio of high-grade tears in adolescent females at delivery, compared to adult females, was 1.36 (95% CI = 0.99-1.86, p= 0.05). No difference was found when comparing risk factors among high-grade tear deliveries in adolescents versus adults.</p> <p><strong>Conclusions:</strong> A higher prevalence than previous reported for high grade tears during delivery was found. The data suggest adolescence as a risk factor for high-grade tears during delivery.</p>}, number={4}, journal={Colombia Medica}, author={Sánchez Ávila, María Teresa and Galván Caudillo, Marisol and Cantú Pompa, Jaime Javier and Vázquez Romero, Natalia and Martínez López, Jhanea Patricia and Matías Barrios, Víctor Manuel and Avitia Herrera, Abryl Mariana and Morales Garza, Luis Alonso and Hernández Escobar, Claudia Eugenia and Soto Fuenzalida, Gonzalo and González Garza, María Teresa}, year={2018}, month={Dec.}, pages={261–264} }
