1039 — Physical Activity among Veterans with Diabetes

Bouldin ED, Seattle HSR&D Center of Excellence; Reiber GE, Seattle HSR&D Center of Excellence, University of Washington;

To determine the prevalence of meeting physical activity (PA) recommendations among Veterans with and without diabetes and to identify factors associated with PA.

Data from the 2009 Behavioral Risk Factor Surveillance System, a representative telephone survey of US adults, were used in this study. Respondents were classified as having diabetes if they reported ever being diagnosed with diabetes except during pregnancy. Respondents who reported ever serving on active duty in the military, National Guard, or military reserve, but who were not on active duty at the time of the survey were classified as Veterans. Based on self-reported physical activity, we classified respondents as meeting PA recommendations (>=150 minutes moderate-intensity PA or >=75 minutes vigorous-intensity PA each week), not meeting PA recommendations, or engaging in no PA. We calculated frequencies and 95% confidence intervals (95%CI) for categorical variables. We modeled the ordinal physical activity outcome using a cumulative logit regression model to produce adjusted odds ratios (aOR). All analyses were completed using survey procedures in SAS.

Among 427,025 respondents, 55,744 (10.6% weighted) were Veterans. Half of Veterans and non-Veterans met PA recommendations (49.0% and 49.2%, respectively; p = 0.07). After adjusting for age, sex, race and ethnicity, household income, education level, disability status, body mass index (BMI), and recent health check-up, Veteran status was associated with a small but significantly increased odds of meeting PA recommendations (aOR = 1.07, 95%CI 1.03-1.11). Among Veterans, diabetes was associated with a significantly reduced odds of meeting PA recommendations (aOR = 0.79, 95%CI 0.73-0.87). Veterans with a disability were half as likely as Veterans without disability to meet PA recommendations in the fully adjusted model (aOR = 0.52, 95%CI 0.48-0.55). Veterans who were classified as obese based on their BMI also were less likely to meet PA recommendations than Veterans in the ideal BMI category (aOR = 0.62, 95%CI 0.56-0.68).

After adjustment for demographic and health factors related to PA, Veterans were significantly more likely to meet PA recommendations than non-Veterans. Among Veterans, diabetes, disability, and obesity were inversely associated with meeting PA recommendations.

Clinicians who provide Veteran care can better target advice to patients with diabetes, particularly those with disabilities.
