[Exactitude of self-reported weight and height in 15 to 19 year old female adolescents of the State of Mexico]. / Exactitud del autorreporte de peso y talla en mujeres de 15 a 19 años del Estado de México.

OBJECTIVE: To know the accuracy of weight and height in 15 to 19 years old women in relation to age, marginalization and migratory intensity level of localities and father's academic level. MATERIALS AND METHODS: The study was carried out with a probabilistic sample of public high school students at the State of Mexico (N=2 357), to whom self-reported weight and height were asked and were directly measured afterwards. Data were collected from January to April 2007. RESULTS: The results obtained showed that these adolescents overestimate their height not significantly, and significantly underestimate their weight, with similar trends analyzing age, marginalization levels, migratory intensity and father's education status. CONCLUSIONS: Results show the validity of self-reported height but not of self-reported weight among this sample.

Exactitud del autorreporte de peso y talla en mujeres de 15 a 19 años del Estado de México / Exactitude of self-reported weight and height in 15 to 19 year old female adolescents of the State of Mexico

OBJETIVO:Conocer la exactitud del autorreporte del peso y la talla en mujeres adolescentes de 15 a 19 años en función de la edad, el nivel de marginación, la intensidad de migración de las localidades y la escolaridad del padre. MATERIAL Y MÉTODOS:Se obtuvo una muestra representativa de mujeres estudiantes en escuelas públicas de nivel medio superior en el Estado de México (N=2 357) a quienes se les solicitó el dato por autorreporte del peso y la estatura y luego se las midió y pesó. Los datos se recopilaron durante los meses de enero a abril de 2007. RESULTADOS:Las adolescentes sobrestimaron su estatura de manera no significativa y subestimaron en grado significativo su peso, con tendencias similares al analizar por edad, nivel de marginación, intensidad de migración y escolaridad del padre. CONCLUSIONES:Los resultados muestran la validez del autorreporte de la estatura, mas no del peso corporal en esta muestra.

[Early onset depression: prevalence, course, and treatment seeking delay]. / La depresión con inicio temprano: prevalencia, curso natural y latencia para buscar tratamiento.

OBJECTIVE: To estimate the prevalence of early onset depression in the Mexican population and compare its natural history, comorbidity and treatment latency between early onset and adult onset depression. MATERIAL AND METHODS: The National Survey of Psychiatric Epidemiology (ENEP) is representative of the Mexican urban population aged 18 to 65. The diagnostic instrument is the Composite International Diagnostic Interview (CIDI). Statistical analysis was performed with descriptive and logistic regression analyses, considering the multistage, stratified and weighted sample design of the survey. RESULTS: Two percent of the Mexican population has suffered from depression as children or adolescents, with an average 7 episodes during their lifetime (compared with 3 episodes for adult onset); the first episode lasted a mean of 31 months (compared with 16 for adult onset) and generally did not receive any treatment. CONCLUSIONS: The longer duration of the first episode and the greater number of lifetime episodes for subjects with early onset is attributed to the lack of early detection and of timely treatment of depression in Mexican youth.

La depresión con inicio temprano: prevalencia, curso natural y latencia para buscar tratamiento / Early onset depression: prevalence, course, and treatment latency

OBJETIVO: Conocer, en la población mexicana, la prevalencia de la depresión con inicio temprano, y comparar el curso natural, la comorbilidad y la latencia para buscar tratamiento entre los deprimidos con inicio temprano y aquellos con inicio en la edad adulta. MATERIAL Y MÉTODOS: La Encuesta Nacional de Epidemiología Psiquiátrica es representativa de la población nacional urbana, de entre 18 a 65 años de edad. Se realizó en México, entre 2001 y 2002, con el instrumento diagnóstico de la versión computarizada de la Entrevista Internacional Compuesta de Diagnóstico. Los análisis toman en cuenta el diseño complejo de la muestra multietápica, estratificada y ponderada utilizando análisis descriptivo y regresiones logísticas. RESULTADOS: El 2.0 por ciento de la población ha padecido depresión en la infancia o adolescencia con un promedio de siete episodios a lo largo de la vida (comparado con tres para los de inicio en la adultez), el primero persiste por unos 31 meses (comparado con 16 meses), durante los cuales generalmente no reciben tratamiento. CONCLUSIONES: La mayor duración del primer episodio y el mayor número de episodios en la vida de aquellos con depresión de inicio temprano se debe a la falta de detección y tratamiento oportuno en jóvenes.
