Resumen Introducción Existe alta prevalencia de alteraciones emocionales en la población expuesta a desastres y los centros de atención primaria de salud (APS) podrían contribuir a su prevención. Objetivo Analizar asociaciones post-catástrofe entre variables de APS y variables de salud mental de la población. Método Estudio efectuado en Chile un año después de un terremoto de 8,8° Richter. Se aplicó un cuestionario de intensidad de acciones de salud mental en 16 centros APS y las escalas GHQ-12 y SF-36 para malestar psicológico y calidad de vida en una muestra basada en hogares y otra de consultantes a APS. Se efectuó un análisis de regresión lineal múltiple para las dos poblaciones y los dos instrumentos. Resultados Ninguna de las variables sobre intensidad de acciones de APS mostró relación con GHQ-12 o SF-36 en ambas muestras. Las variables asociadas significativamente a mayor puntaje en GHQ-12 y menor puntaje en SF-36 fueron sexo femenino, baja escolaridad, baja situación económica, menor apoyo social y daños producidos por el terremoto. Conclusión El equipo APS podría lograr un mayor efecto preventivo post-catástrofe trabajando con otros sectores que incluyan la dimensión salud mental en el abordaje de los problemas sociales críticos en situaciones de desastres, y reservando el trabajo preventivo directo para las personas con alta vulnerabilidad psicológica. Abstract Background There is a high prevalence of emotional disturbances in the population exposed to disasters, and primary health care centers (PHC) could contribute to their prevention. Objective To analyze post-catastrophe associations between PHC variables and population mental health variables. Method Study conducted in Chile one year after an 8.8° Richter earthquake. We applied a questionnaire on the intensity of mental health actions in 16 PHC centers, and scales GHQ-12 and SF-36 for psychological distress and quality of life, in a sample based on households and consultants of the PHCs. We used multiple linear regression analysis for the two samples and the two instruments. Results The variables on PHC intensity of actions showed no association with the GHQ-12 or SF-36 scores in both samples. The main variables significantly associated with higher scores on GHQ-12 and lower scores on SF-36 were female gender, fewer years of schooling, negative economic situation, less social support and physical damages caused by the earthquake. Conclusion The PHC teams could achieve greater preventive post-disaster outcome working with other sectors, including mental health dimensions, while addressing the critical disaster social issues, and focusing direct preventive work on those psychologically vulnerable.

Background: Thirty to 50% of people exposed to a natural disaster suffer psychological problems in the ensuing months. Aim: To characterize the activities in mental health developed by Primary Health Care centers after the earthquake that affected Chile on february 27th, 2010. Material and Methods: A cross-sectional study analyzing 16 urban centers of Maule Region, was carried out. A questionnaire was developed to know the preparatory and supportive activities directed to the community and the training and self-care activities directed to Health Care personnel that were made during the 12 months following the catastrophe. In addition, a questionnaire evaluating structural aspects was designed. Results: Only 1/3 of the centers made some preparatory activity and none of them made a diagnosis of population vulnerability. The average of protective Mental Health interventions coverage reached 35% of the population estimated to be most affected. The activities lasted 31 to 62% of the optimal duration standards set by experts (according to the type of action). Important differences between centers in economic and geographical accessibility, construction and professional resources were found. Conclusions: This study shows the difficulties faced by urban centers of Maule Region to deal with mental health problems caused by the earthquake, which were attributable to the absence of local planning and drills, and to the lack of intra and inter sectorial coordination.
