Abstract: An analysis device in a parent-child health management system receives a sensor output from a sensor terminal and an answer to a questionnaire from a user terminal. At least one of parent's life information and child's life information is analyzed based on the answer to the questionnaire to generate a life information analysis result. A sensor output analysis unit generates, based on the sensor output, a sensing result including at least one of a parent-child relationship, a parent's health condition, and a child's health condition. A health estimation unit is configured to compare the life information analysis result and the sensing result with a predetermined criterion to estimate at least one of a parent-child state, a parent's state, and a child's state. An output unit is configured to select a questionnaire and advice corresponding to the estimated state and output the selected questionnaire and advice to the user terminal.
