[Evaluation of the One-Year Multimodal Weight Loss Program DOC WEIGHT® 1.0 for Obesity Class II and III].

According to treatment guidelines, treatment for obesity (body mass index [BMI] >= 30.0 kg/m(2)) comprises nutritional, physical, and behavioral interventions. However, evidence-based programs for the treatment of severe obesity are rare. In an uncontrolled study, a total of 190 participants (BMI >= 35.0 kg/m(2)) of the one-year multimodal treatment program DOC WEIGHT (R) 1.0 were assessed at pre-(t(0)) and post-intervention (t(1)) as well as at 1-year follow-up (t(2)). Results revealed significant improvements from t(0) to t1 in body weight, waist circumference, eating disorder psychopathology, and quality of life that persisted to t(2). Long-term multimodal outpatient treatment for severe obesity focusing on behavior modification is promising, however, high rates of loss to follow-up limit explanatory power. To improve evidence, consecutive evaluation is intended.
