Methods: Case-control study, conducted with 570 pregnant adolescents and 2093 ≥20 years of age whose infants were hospitalized in a neonatal unit. Associations were determined by Odds Ratio with confidence interval of 95%, using the multivariate logistic regression analysis. To build the model with Classification and Regression Trees variables in the bivariate had had a p<0.05 was used.

Influencia de la adolescencia y su entorno en la adherencia al control prenatal e impacto sobre la prematuridad, bajo peso al nacer y mortalidad neonatal

Introduction. College students who engage in sexual intercourse at an early age have more sexual partners, and are more likely to engage in risky sexual behaviors. These make them more vulnerable to sexually transmitted diseases and unintended pregnancies. Method. A cross-sectional study was performed on 1854 university students between the ages of 18 and 24 from the health care areas (medicine, nursing, dentistry, and psychology) at two public universities in the State of Mexico. Correlations were established through X ² among the early onset of sexual intercourse, the number of sexual partners, group sex, transactional sex, and casual sex. Results . Men initiate sexual intercourse at younger ages than women. In men, there are statistically significant ( p =.001) correlations between the early onset of sexual intercourse and casual, transactional and group sex. In women, there are statistically significant correlations between the early onset of sexual intercourse and casual sex, and having more than five sexual partners. Conclusion . Students who engage in sexual intercourse at an early age have more sexual partners, and are more likely to engage in casual, transactional and group sex. These risky sexual behaviors make them more vulnerable to sexually transmitted diseases and unintended pregnancies.

Objective. To analyze the social determinants that condition early sexual activity of adolescents. Methods. Quantitative, descriptive, explanatory and cross-sectional study. The sample comprised 254 students between 14 and 18 years of age. A questionnaire was applied to them. It evaluated the personal, family and contextual dimensions and the initiation of sexual activity. For the analysis of the relationship between variables, chi-square statistical test and multiple linear regression model were used. Results. Personal conditioning factors, age of sexual initiation, lack of contraceptive use, and little knowledge of the signs and symptoms of sexually transmitted infections were identifed. Among determinants related to their families, level of education of their parents, support from their mothers, and verbal and physical violence appearto have a signifcant association. Along with the lack of habit of going to health services, television programs and friends appear as the ones that most promote the initiation of early sexual activity. Conclusions. Personal, family and contextual are determinants that signifcantly inﬂuence initiation of adolescent sexual activity, aﬀecting their sexual and reproductive health.

Factors Associated with Sexual Debut in Mexican Adolescents: Results of the National Survey on Drug Use among Students in 2014.

Objetivo: Determinar la prevalencia de actividad sexual (AS) y factores asociados del debut sexual en adolescentes escolarizados de una ciudad colombiana. Metodos: Estudio observacional, de corte transversal, con 947 estudiantes de 14 a 19 anos. Las asociaciones se determinaron mediante Odds Ratio con 95% de intervalo de confianza. Para el analisis multivariado se empleo regresion logistica. Resultados: La prevalencia de AS fue 52,8%. La mediana de edad de inicio fue 15 anos (RI: 14-16). Las variables asociadas al inicio temprano de la AS para el nivel individual fueron: sexo masculino, aprobacion y actitudes permisivas hacia el sexo del adolescente, consumo de licor, tabaco y drogas. Para el nivel familiar fueron: madre no da educacion sexual al hijo, hermano/a que en la adolescencia hayan sido padre/madre, aprobacion y actitudes permisivas de los padres hacia el sexo en la adolescencia. Para el nivel socio-cultural fueron: como factores de riesgo el pertenecer a los estratos socioeconomicos 1 y 2, aprobacion y actitudes permisivas de los pares o grupo de amigos del adolescente a la AS en la adolescencia, y como factor protector el haber recibido educacion en anticoncepcion por personas diferentes a los padres, como equipos de educacion en colegios o personal de salud. Conclusion: Factores individuales como sexo masculino, propia toma de decisiones, papel que desempena la madre en la educacion sexual de sus hijos y la influencia de pares o amigos en la toma de decisiones, se asociaron con el inicio temprano de la AS entre adolescentes.
