A small-change approach delivered via telephone promotes weight loss in veterans: results from the ASPIRE-VA pilot study.

OBJECTIVE

High rates of overweight and obesity (70%) among US veterans pose a significant threat of obesity-related chronic disease and disability. The purpose of this pilot study was to demonstrate feasibility and impact of a phone-based small-change weight loss intervention (ASPIRE-VA) with veterans.

METHODS

Participants received a pedometer, food log book, and treatment manual outlining the small change program. Participants then scheduled weekly phone calls with a lifestyle coach, during which they reviewed the prior week's goals and developed new goals for the following week. Primary outcome was weight loss measured at 12 weeks, compared to baseline.

RESULTS

Fourteen sedentary (4471+/-2315 steps per day), obese (37.0+/-4.2 BMI), middle aged (53.8+/-12.5) male (64%) and female (36%) participants were enrolled. At 12 weeks participants exhibited significant weight loss (-3.8+/-3.6 kg; p=.002) and increased intake of fruits and vegetables (+2.2+/-3.1 daily servings; p=.03); though no change in walking (+786+/-2288 daily steps; p=.24).

CONCLUSION

Results suggest that a phone-based small change program is feasible and beneficial for promoting weight loss in overweight/obese veterans.

PRACTICE IMPLICATIONS

This telephone-based program has the potential to reduce rates of overweight and obesity among veterans and thus prevent and improve prognosis of associated chronic conditions.
