Fear of InjuryWith Physical Activity Is Greater in AdultsWith Diabetes Than in AdultsWithout Diabetes

OBJECTIVE—Physical activity is a cornerstone of treatment for diabetes, yet people with diabetes perform less moderate and vigorous physical activity (MVPA) than people without diabetes. In contrast, whether differences in walking activity exist has been understudied. Diabetes-specific barriers to physical activity are one possible explanation for lower MVPA in diabetes. We hypothesized that people with diabetes would perform less walking and combined MVPA and would be less likely to anticipate increasing physical activity if barriers were theoreti-cally absent, compared with people without diabetes. RESEARCH DESIGN AND METHODS—We surveyed 1,848 randomly selected rural Colorado adult residents by telephone from 2002 to 2004. Respondents reported weekly walk-ing and MVPA duration and their likelihood of increasing physical activity if each of seven barriers was theoretically absent. RESULTS—People with diabetes (n = 129) had lower odds of walking and MVPA than people without diabetes (walking: adjusted odds ratio 0.62 [95%CI 0.40–0.95]; MVPA: adjusted odds ratio 0.60 [0.36–0.99];$10 vs.,10 min/week, adjusted for age, sex, BMI, and ethnicity). Respondents with diabetes reported fear of injury as a barrier to physical activity more often tha
