In this paper, we first describe the current state of health across the world. We then note that despite general good health, it is not everyone's experience and that differences in health among people frequently appear to be unfair. Health promotion is a movement committed to prevention and to creating opportunities for all people to live healthy lives. We examine the application of health promotion to people with intellectual disability. Finally, we bring equity, health promotion and intellectual disability together and ask to what extent people with these problems are victims of inequity. If they are--as seems likely--societies that have built their health services on humane values should assume greater responsibility for meeting their special needs, promoting their opportunities for health as well as managing their illnesses.
