RESUMEN
OBJECTIVE: To review first-year results of a clinic-based type 2 diabetes prevention program. METHODS: From January through December 2007, patients with a diagnosis of prediabetes participated in the Diet-Exercise-Activity-Lifestyle program for instruction in lifestyle changes. Physical therapy assessments were retrospectively reviewed to search for symptoms or findings of physical impairments. Changes in weight and 2-hour glucose tolerance test results were assessed at 6 months. Patient satisfaction with the program was evaluated. RESULTS: Ninety-two patients qualified for the program. Mean baseline fasting glucose concentration was 108 mg/dL, and 2-hour glucose concentration was 134 mg/dL. Mean age was 62 years, and 66% were women. Review of physical therapy assessments demonstrated gait/balance disturbances in 47% of patients, peripheral neuropathy in 43%, and musculoskeletal problems in 63%. Among 47 patients who had 6-month follow-up visits, 72% lost weight. Fasting glucose levels improved in 58% in persons with impaired fasting glucose, and 2-hour glucose values decreased in patients who had impaired glucose tolerance. Seventy-eight percent graded the program as either "very good" or "excellent." CONCLUSIONS: Programs geared toward type 2 diabetes prevention can be feasibly implemented on an outpatient basis. Preliminary data suggest that improvements in weight and glucose values can be achieved. As the prevalence of prediabetes increases, health care systems must gain further experience with effective outpatient diabetes prevention strategies.
