Madres niñas-adolescentes de 14 años y menos: Un grave problema de salud pública no resuelto en Chile

Background: Teenage fecundity rates are an indicator of epidemiological discrimination in developing countries. Aim: To study fertility rates of girls under 14 years of age in Chile from 1993 to 2003. Material and methods: Information of children born alive from mothers aged 10 to 15 years, was obtained from the Chilean National Institute of Statistics. Age segmented population data was obtained from the Ministry of Health. Trends were analyzed by regions and single ages. The rates in communities of the Metropolitan Region were compared. Results: Between 1993 and 2003, there was an increasing trend in fecundity rates, ratios and crude numbers. These rates duplicate from 14 to 15 years of age. In the Metropolitan Region, the fecundity ratios of communities with lower economical incomes is seven times greater than those with higher incomes. During 2003, the fecundity rates in Chile were 100 and 10 higher than those of Holland and Sweden in 1981. Conclusions: In developing countries with very low infant mortality rates such as Chile, the high fecundity rates of young girls is an indicator of a deficient human and social development. Sexual Education and Health Services for adolescents are essential to prevent this public health problem

Adolescentes discapacitados: talleres de afectividad y sexualidad

La medicina ha prolongado la vida de pacientes cronicos y discapacitados que fallecian antes de la adolescencia. Uno de los problemas que enfrentan es la negacion de su sexualidad por la sociedad y la familia. Durante 3 anos (1996-1998), 32 adolescentes discapacitados o portadores de patologias cronicas, participaron en el Centro de Medicina Reproductiva y Desarrollo Integral del Adolescente (CEMERA), de la Facultad de Medicina de la Universidad de Chile, en un programa de talleres para el abordaje de la afectividad y la sexualidad. Veinticinco madres de adolescentes discapacitados participaron tambien en talleres paralelos. Fueron evaluados con un test previamente probado con adolescentes sin discapacidad, al inicio, al final y 6 meses despues. El nivel de autoestima (test de Coopersmith) y los conocimientos adquiridos en reproduccion y afectividad aumentaron significativamente y se mantuvieron a 6 meses de seguimiento. Los conocimientos de las madres tambien presentaron un aumento significativo. Reconocer los sentimientos de las madres podria mejorar la relacion medico-paciente-familia. Se recomienda esta metodologia de trabajo para la educacion en afectividad y sexualidad, asi como para el apoyo integral a este tipo de adolescentes y sus familias

Diferencias de género en la calidad de vida relacionada con la salud en adolescentes escolarizados chilenos

Background: Health-related quality of life (HRQOL) refers to individuals´ perception of their subjective well-being, considering various aspects of their life and the impact on their health. Aim: To analyze gender differences in the HRQOL of adolescent students in Chile, by age, type of school attended, and area of residence. Material and methods: Analytical cross-sectional study conducted in a population of 5th and 12th grade students attending municipal, subsidized and private schools in 11 regions of the country. HRQOL was assessed with the KIDSCREEN-52, an instrument that has been previously adapted and validated in Chile. The database obtained from that adaption and validation process was analyzed. Results: In total, 7,910 students (median age 14 years, 53% female) completed the questionnaire. Compared to males, females had lower HRQOL scores in most of the KIDSCREEN-52 dimensions. However, males were more likely to have lower scores in the “Peers and Social Support” and “School Environment” dimensions. These differences remained valid when the sample was stratified by age, type of school, and area of residence were analyzed. Conclusions: This study supports the existence of inequalities in the self-perceived HRQOL of Chilean adolescent students. The existing differences are not only related to gender but are also evident when stratifying by type of school attended.

Patrón intergeneracional del embarazo adolescente en las hijas de una cohorte de mujeres que controlaron su primer embarazo en un centro integral para adolescentes embarazadas

Antecedentes: Las circunstancia desventajosas de las madres adolescentes tienden a repetirse, con consecuencias aun mas graves en la vida de sus hijas, que suelen tener dificultades escolares y se embarazan a una edad incluso mas temprana que sus propias madres. Objetivo: Examinar el patron intergeneracional del embarazo adolescente en las hijas de una cohorte de mujeres que fueron madres adolescentes. Metodo: Estudio transversal medido en dos momentos, de una cohorte historica de mujeres que controlaron su primer embarazo en un centro especializado en la atencion de adolescentes embarazadas. La informacion de las madres se obtuvo en la primera entrevista que se aplico al ingreso prenatal y la de las hijas fue obtenida cuando estas eran adolescentes. Se analizaron las caracteristicas de las madres y de las hijas que se embarazaron. Posteriormente se compararon las caracteristicas entre las hijas que se embarazaron y aquellas que no. Resultados: En el 21% las hijas se embarazaron, aunque menor a lo que reporta la literatura, es igualmente preocupante porque un embarazo en la adolescencia altera en general la trayectoria estudiantil y el proyecto de vida de la adolescente. Las hijas repitieron consecuencias adversas, pero lograron tener exito en la permanencia escolar y sus madres tuvieron menos hijos que las abuelas, como resultado positivo del programa. Conclusion: Programas de atencion integral con profesionales entrenados en la atencion de adolescentes embarazadas pueden tener un impacto positivo importante en la reduccion de los patrones reproductivos intergeneracionales del embarazo adolescente.
