Objetivo. Caracterizar a las adolescentes que han tenido algún embarazo y analizar la asociación de éste con el rezago educativo, a partir de una encuesta representativa en México. Material y métodos. Estudio transversal con información de la Encuesta Nacional de Salud y Nutrición (Ensanut) 2012, con datos sociodemográficos y reproductivos de 1 790 mujeres de 12 a 19 años de edad con inicio de vida sexual y antecedente de embarazo. Se ajustaron tres modelos estadísticos para observar la asociación entre variables. Resultados. El rezago educativo está presente en 74.9% de las adolescentes con antecedente de embarazo. Tener embarazo previo está asociado con cohabitar con la pareja (RM=8.4), rezago educativo (RM=2.4), nivel socioeconómico bajo (RM=2.0) y asistencia a la escuela (RM=0.5). El rezago educativo muestra una asociación con el antecedente de embarazo alguna vez en la vida (RM=2.4), no así con el primer embarazo al momento de la encuesta. Conclusión. Se requieren políticas y estrategias operativas eficientes para favorecer la permanencia escolar y reducir el rezago educativo en adolescentes con y sin hijos.

Adolescent pregnancy is associated with poor health and socioeconomic factors. The adolescent pregnancy rate in Mexico is the highest among the Organization for Economic Co-operation and Development (OECD) countries. We aimed to explore the factors associated with pregnancies and births in adolescent and young adult women. Using the 2015 Mexican National Survey of Boys, Girls, and Women (ENIM), we examined two dichotomous outcomes: “ever pregnant” and “being a mother” in women from 15 to 19 years and from 20 to 24 years without pregnancies during adolescence. We conducted bivariate analysis for each age group and used general linear models (GLM) to assess the association between the outcome variables and selected socioeconomic variables. Among adolescents, school attendance and tertiary education significantly decreased the likelihood of ever having been pregnant or being mothers, while being married/cohabiting increased the likelihood. Older age at first intercourse was negatively associated with ever having been pregnant. For adult women, in addition to school attendance, tertiary education, and being married/cohabiting, the region of residence also showed a significant association with ever having been pregnant. Similar socioeconomic factors were associated with pregnancy and motherhood between adolescents and young adults. However, it was found that delaying sexual debut could reduce the adolescent pregnancy rate. Our results highlight the importance of attending school and attaining tertiary education in reducing adolescent fertility rates.

Breast cancer has become an important health risk for women worldwide.The important growth of breast cancer-related deaths within those caused by malign tumors throughout the globe went past the 460 000 in 2008,becoming the deadliest disease worldwide. Demographic changes and lifestyles have modified the population exposure to risk factors of maladies such as cancer, and since 1980 breast cancer mortality has remained on an upward tendency, surpassing cervical cancer in 2006. After analyzing mortality rates along 30 years in Mexican women 25 or more years old, differences by state and age-groups are apparent. Although this cause of death has been associated with a highest regional development, some changes are taking place,since the number of deaths is also growing among women of less-developed regions in the country,as showed in this work. Mexico faces an evident challenge regarding breast cancer. Our country requires to join efforts and implement programs aimed at teaching self-care of health among the population,promoting healthier lifestyles, and reshaping our diagnostic infrastructure to achieve earlier detection and provide proper treatment.

Strategies for standardization and quality control for the clinical breast examination are needed to contribute in the prevention and control of breast cancer in Mexico.
