Procesos educativos sobre enfermedad de Chagas con escolares de nivel básico de escuelas públicas de México / Educational processes on Chagas disease in schoolchildren from public schools in Mexico

Se presentan los cambios en conocimientos y prácticas sobre el vector y la enfermedad de Chagas con escolares de México posterior a una intervención educativa. La identificación del vector aumentó posterior a las sesiones educativas (pre=36,15% vs post=79,30%). Aumentaron los conocimientos acerca de la enfermedad de Chagas (30,90% vs 64,72%, valor de p< 0,0001) y de las acciones preventivas para evitar que el vector habite dentro de sus entornos (14,29% vs 61,81%, valor de p< 0,0001). Los escolares pueden jugar un papel fundamental en la prevención de esta problemática(AU)

Population health diagnosis with an ecohealth approach.

OBJECTIVE: To analyze the characteristics of health diagnosis according to the ecohealth approach in rural and urban communities in Mexico. METHODS: Health diagnosis were conducted in La Nopalera, from December 2007 to October 2008, and in Atlihuayan, from December 2010 to October 2011. The research was based on three principles of the ecohealth approach: transdisciplinarity, community participation, gender and equity. To collect information, a joint methodology and several techniques were used to stimulate the participation of inhabitants. The diagnostic exercise was carried out in five phases that went from collecting information to prioritization of problems. RESULTS: The constitution of the transdisciplinary team, as well as the participation of the population and the principle of gender/equity were differentials between the communities. In the rural community, the active participation of inhabitants and authorities was achieved and the principles of transdisciplinarity and gender/equity were incorporated. CONCLUSIONS: With all the difficulties that entails the boost in participation, the incorporation of gender/equity and transdisciplinarity in health diagnosis allowed a holistic public health approach closer to the needs of the population.

OBJETIVO Analizar las características del diagnóstico de salud según el enfoque de ecosalud en comunidades rural y urbana en México.MÉTODOS Los diagnósticos de salud se efectuaron en La Nopalera, de diciembre 2007 a octubre 2008 y en Atlihuayan de diciembre 2010 a octubre de 2011. Se basó en tres principios del enfoque de ecosalud: transdiciplina, participación comunitaria, género y equidad. Para colectar la información se utilizó una metodología mixta y diversas técnicas para estimular la participación de los habitantes. El ejercicio de diagnóstico se efectuó en cinco fases que oscilaron desde la recolección de información hasta la priorización de problemas.RESULTADOS La constitución del equipo transdisciplinario, así como la participación de la población y el principio de género/equidad fue diferencial entre las comunidades. En la comunidad rural, se logró la participación activa de los pobladores y autoridades y se incorporaron los principios de transdisciplina y género/equidad.CONCLUSIONES Con todas las dificultades que acarrea el impulso de la participación, la incorporación del género/equidad y la transdisciplina en el diagnóstico de salud, permitió un abordaje holístico de salud pública más cercano a las necesidades de la población.

[Validation of reported location of solid waste using Procrustes analysis in the context of a participatory community initiative]. / Validación del auto-reporte de la localización de residuos sólidos con análisis de Procusto en el contexto de una iniciativa comunitaria participativa.

This study is part of a community initiative for integrated solid waste management based on "popular epidemiology" and participatory action research. The study proposes a method for validation of spatial data (X and Y data) on solid waste reported by community members. Location of sites was conducted by 76 residents of the La Nopalera community (Yautepec, Morelos, Mexico) and compared with reports by three environmental health experts. Agreement was explored using Procrustes analysis. Experts identified 23 sites with abundant solid waste, while community members only identified 22 sites. There were minimal differences in location, scale, and positioning of reported waste. Procrustes statistics showed 95% agreement between community and expert reports. The findings suggest that community knowledge can be a valid source of information in epidemiological studies, and that measurement error can be quantified. The simple methodology described here can be used in further "popular epidemiology" studies or similar approaches.

Este estudio forma parte de una iniciativa comunitaria de manejo integral de residuos, basada en "epidemiología popular" y la investigación acción participativa. En este estudio se propone un método de validación de datos espaciales (ordenadas y abscisas) de residuos sólidos auto-reportados por la comunidad. La ubicación de los sitios fue realizada por 76 residentes de la localidad La Nopalera (Yautepec, Morelos, México), y comparada con los reportados por tres expertos en salud ambiental. La concordancia fue explorada con análisis de Procusto. Los expertos identificaron 23 sitios de concentración de residuos sólidos, mientras que la comunidad ubicó solo 22 sitios. Hubo mínimas diferencias en la localización, escala y orientación. El estadístico de Procusto mostró 95% de concordancia entre legos y expertos. Los hallazgos sugieren que el saber popular es una fuente de información válida en estudios epidemiológicos, y que su error de medición puede ser cuantificado. La sencilla metodología descrita podrá ser usada en futuros estudios de "epidemiología popular" o aproximaciones similares.
