1. A system for monitoring health parameters of a distributed plurality of ambulatory subjects, comprising: a network, comprising: a computer; a remote node accessing the computer; a data storage device receiving and storing data acquired by the system; and a data analysis means in the computer for analyzing acquired data; a physiological monitoring subsystem coupled to the network, being operative to measure physiological parameters of the plurality of subjects and transmit parameter signals corresponding to measurements of the physiological parameters to the data storage device; a behavioral and cognitive monitoring subsystem coupled to the network, being operative to measure behavioral and cognitive parameters of the plurality of subjects and transmit behavioral and cognitive signals corresponding to measurements of the behavioral and cognitive parameters to the data storage device; and a passive personal tracking subsystem coupled to the network, operative to generate tracking signals from tracking transmitters associated with each subject, said tracking signals corresponding to the identities and locations of each of the plurality of ambulatory subjects; wherein the data analysis means is operative to associate the tracking signal of a first subject with a parameter signal of the first subject or a behavioral and cognitive signal of the first subject to form a data record.
