This document notes that, as health care costs continue to rise, the elderly are monitoring themselves as a means of cost containment, and as a way of enhancing their sense of well-being and their ability to lead active lives. It points out that more and more organizations are sponsoring health programs that promote the concept of self-care and self-help practices, and that many of these programs have been tailored to the special needs of the elderly. The document provides a directory of information about a broad variety of national organizations that deal specifically with the elderly, or that have programs relevant to older people, their families, and health professionals who work with them. The organization name, address, telephone number, membership information, and a general and health-related description are given for each of the directory's 90 entries. Information on the organizations' periodicals, publications, and other media is given for organizations involved in these activities. Listings include organizations concerned with specific health problems such as Alzheimer's Disease, cancer, diabetes, or heart disease; religious organizations; and organizations concerned with various aspects of aging.
