          Abstract

          Objetivo: Estimar la edad promedio de inicio de las relaciones sexuales con penetración (IRSP) y los factores familiares e individuales asociados en chicos y chicas de 14-19 años escolarizados en centros públicos de las 32 entidades de México, en 2007. Métodos: Estudio transversal realizado en una muestra representativa de 9893 estudiantes de 14-19 años de edad. La información se recolectó utilizando un cuestionario autoadministrado, anónimo y voluntario. Se estimaron modelos de regresión logística para obtener odds ratio (OR) e intervalos de confianza del 95% (IC95%) por categorías: sin IRSP, IRSP a los 10-15 años años e IRSP a los 16-19 años. Resultados: El promedio de edad nacional para el IRSP fue de 16 años (IC95%: 15,5-16,1). En los chicos, la media de edad al IRSP fue de 15 años (IC95%: 15,88-16,11), y en las chicas fue de 16 años (IC95%: 15,26-15,42). Factores asociados a IRSP en chicos: nivel socioeconómico desfavorecido (OR = 0,66; IC95%: 0,46-0,94), vivir con los padres (OR = 0,65; IC95%: 0,56-0,75), comunicación ofensiva menor entre padres/madres e hijos/as (OR = 0,66; IC95%: 0,57-0,77)¸ autoestima social alta (OR = 1,68; IC95%: 1,35-1,77). Factores asociados a IRSP en chicas: creencias de género tradicionales (OR = 0,49; IC95%: 0,32-0,74), sintomatología depresiva alta (OR = 1,88; IC95%: 1,19-2,99), autoestima familiar alta (OR = 0,50; IC95%: 0,38-0,65). Conclusiones: En México, el IRSP se presenta a edad más temprana en los chicos. Además, los hallazgos del presente estudio demuestran que la edad de IRSP y los factores asociados son diferentes en los chicos y las chicas. Las creencias de género y socioculturales influyen de manera importante en la edad de IRSP.

          Objective: To estimate the mean age of sexual intercourse debut (SID) and associated family and individual factors in 14-19-year-olds of both sexes in the 32 states of Mexico in 2007. Methods: A cross-sectional study was conducted of a representative sample of 9,893 students aged between 14 and 19 years old. The data were collected through a self-administered, anonymous and voluntary questionnaire. Logistic regression models were used to estimate odds ratios (OR) with 95% confidence intervals (95%CI) by category: no SID, SID at 10-15 years and SID at 16-19 years. Results: The national mean age of SID was 16 years, being 15 years for boys (95%CI: 15.88-16.11) and 16 years for girls (95%CI: 15.26-15.42). Factors associated with SID in boys were disadvantaged socioeconomic level (OR = 0.66; 95%CI: 0.46-0.94), living with parents (OR = 0.65; 95%CI: 0.56-0.75), less offensive communication between parents and boys/girls (OR = 0.66; 95%CI: 0.57-0.77), and high social self-esteem (OR = 1.68; 95%CI: 1.35-1.77). Factors associated with SID in girls were traditional gender beliefs (OR = 0.49; 95%CI: 0.32-0.74), high depressive symptoms (OR = 1.88; 95%CI: 1.19-2.99), and high family self-esteem (OR= 0.50; 95%CI: 0.38-0.65). Conclusions: In Mexico, SID occurred early in boys. In addition, the findings of this study show that in Mexico, the age of SID and associated factors differ in boys and girls. The age of SID is strongly influenced by gender and cultural beliefs.

          Exposure to sexually explicit Web sites and adolescent sexual attitudes and behaviors.

          Mass media play an important role in the socialization of youth. Given its expanding nature and accessibility, the Internet may be at the forefront of this education. However, the extent of the Internet's impact on adolescent sexual attitudes and behaviors is not yet known. A total of 433 adolescents completed an anonymous survey at a health center in New York City. The cross-sectional survey assessed Internet accessibility, exposure to sexually explicit Web sites (SEWs), sexual behaviors, and sexually permissive attitudes. Of the participants, 96% had Internet access, and 55.4% reported ever visiting a SEW. Logistic regression analyses revealed that adolescents exposed to SEWs were more likely to have multiple lifetime sexual partners (OR=1.8, CI=1.2, 2.9), to have had more than one sexual partner in the last 3 months (OR=1.8, CI=1.1, 3.1), to have used alcohol or other substances at last sexual encounter (OR=2.8, CI=1.5, 5.2), and to have engaged in anal sex (OR=2.0, CI=1.2, 3.4). Adolescents who visit SEWs display higher sexual permissiveness scores compared with those who have never been exposed (2.3 vs. 1.9, p
