Enthusiasm for information technology (IT) is growing among older adults. Many older adults enjoy IT and the Internet (Pro-Nets), but others have no desire to use it (No-Nets). This study found that Pro-Nets and No-Nets were different on a number of variables that might predict IT use. No-Nets were older, had less education and income, were retired, in poor health, and less active than Pro-Nets. No-Nets potentially have the most to gain from access to--and training in using--the Internet as a health management tool. Further research with this population could inform the development of health-related web based interventions. (Contains 4 tables.)
