A user-based monitoring system includes a remote user-based subsystem with at least one display and at least two microprocessor-based units in communication with each other. The microprocessor-based units are selected from a data management unit, a personal computer, a handheld device or a user monitoring device. The subsystem is configured to facilitate collection of user-related data. The system also has at least one central server remotely located from and configured for two-way communication with the user-based subsystem so that it can receive and deliver signal communications to and from the user-based subsystem. The system also has at least one authorized user computer remotely located from, and configured for two-way signal communication with, the central server to receive user-related data collected by a remote user-based subsystem and allow an authorized user to communicate with the central server. The system is suited, amongst others, for monitoring remotely the health of a system user.
