OBJECTIVE: To assess differences in demographics, self-care behaviors, and diabetes-related risk factor control by frequency of Internet use.

DESIGN AND PARTICIPANTS: We surveyed 909 patients with type 2 diabetes attending primary care clinics.

MEASUREMENTS: Frequency of Internet use, socioeconomic status, and responses to the Problem Areas in Diabetes (PAID), Summary of Diabetes Self-care Activities (SDSCA), and Health Utilities Index (HUI) scales. Survey responses were linked to last measured hemoglobin Alc, cholesterol, and blood pressure results. Comorbidities and current medications were obtained from the medical record.

RESULTS: Internet “never-users” (n=588, 66%) were significantly older (70.0±11.2 vs 59.0±11.3 years; P<.001) and less educated (26% vs 71% with > high school; P<.001) than Internet users (n=308, 34%). There were few significant differences in PAID or SDSCA scores or in diabetes metabolic control despite longer diabetes duration (10.3±8.2 vs 8.3±6.7 years; P<.001) and greater prevalence of coronary disease (40% vs 24%; P<.001) in nonusers. Less than 10% of current nonusers would use the Internet for secure health-related communication.

CONCLUSIONS: Older and less educated diabetes patients are less likely to use the Internet. Despite greater comorbidity, nonusers engaged in primary care had equal or better risk factor control compared to users.
