[ES]Los efectos del ambiente térmico en la salud humana son bien conocidos, especialmente el aumento de la mortalidad o de los ingresos hospitalarios durante los períodos de altas y bajas temperaturas. Sin embargo, habitualmente se hace uso de los valores absolutos de las temperaturas máximas y mínimas para describir los riesgos asociados sin atender a los cambios interdiarios. En este estudio se aplica una regresión de cuasi-Poisson creando un modelo no lineal de retardo distribuido dentro de un modelo generalizado aditivo con el fin de estimar las asociaciones entre los cambios inter-diarios de las temperaturas máximas y mínimas y la mortalidad en Barcelona y Madrid. Los resultados obtenidos indican en Barcelona efectos de mayor riesgo estadísticamente significativos cuando la diferencia interdiaria es positiva. Con un aumento de 6K de la temperatura aparente máxima se encontró un riesgo relativo de 1,53 (IC95: 1,18 - 1,97) en todas las causas. En cambio, en Madrid se observó un aumento del 11% (IC95%: 1 21%) en las muertes por enfermedades respiratorias cuando la temperatura aparente máxima desciende -12K.
[EN]The effects of the thermal environment on human health are well known, especially the increase in mortality or hospital admissions during periods of high and low temperatures. However, the absolute values of the maximum and minimum temperatures are usually used to describe the associated risks without taking into account the interdaily changes. In this study, a quasi-Poisson regression through a distributed lag model in a framework of generalized additive model is applied in order to estimate the associations between the interdaily changes of maximum and minimum temperatures and mortality in Barcelona and Madrid. For Barcelona the results indicate effects of statistically significant higher risk when the interdaily change is positive. With a 6K increase in the maximum apparent temperature, a relative risk of 1.53 (IC95: 1.18 - 1.97) was found in natural causes. In contrast, in Madrid a mortality increase of 11% (95% CI: 1-21%) was observed due to respiratory diseases when the maximum apparent temperature drops -12K.
