Provided is an organism data processing method and device, storage medium and program that is able to predict and control changes in the state of an organism. The level of expression of molecules in an organism is measured over a set time interval； the measured time-series data is divided into a periodic component, an environmental stimulus response component and a baseline component； a constant region of the time-series data is identified from variations in the baseline component or from the amplitude or periodic variations of the periodic component； and causal relationships within the identified constant region are identified. The relationship between the external environment and variations in the internal environment is identified and from the causal relationships within the identified constant region, changes in the state of the organism are inferred. Further, from the relationship between the external environment and variations in the internal environment, inferring disease onset in the organism is possible. The molecules can be molecules in the blood or molecules in a culture medium.Se proporciona un método y un dispositivo para el procesamiento de información biológica, un medio de registro y un programa que son capaces de pronosticar y controlar los cambios en el estado de un organismo. El nivel de expresión de las moléculas en un organismo se mide durante un intervalo de tiempo específico； los datos en series temporales se dividen en un componente periódico, un componente de respuesta a los estímulos ambientales, y un componente de valor de referencia； las regiones constantes de los datos en series temporales se identifican a partir de las variaciones en el componente de valor de referencia y a partir de las variaciones en la amplitud o periódicas del componente periódico； y se identifica la relación causal entre las regiones constantes identificadas.
