Abstract

Objective: Face-to-face (FTF) weight management is costly and presents barriers for individuals seeking treatment; thus, alternate delivery systems are needed. The objective of this study was to compare weight management delivered by FTF clinic or group conference calls (phone).

Design and methods: Randomized equivalency trial in 295 overweight/obese men/women (BMI = 35.1±4.9, Age = 43.8±10.2, Minority = 39.8%). Weight loss (0-6 months) was achieved by reducing energy intake between 1,200 and 1,500 kcal/day and progressing physical activity (PA) to 300 min/week. Weight maintenance (7-18 months) provided adequate energy to maintain weight and continued 300 min/week of PA. Behavioral weight management strategies were delivered weekly for 6 months and gradually reduced during 7-18 months. A cost analysis provided a comparison of expenses between groups.

Results: Weight change from baseline to 6 months was -13.4 ± 6.7% and -12.3 ± 7.0% for FTF clinic and phone, respectively. Weight change from 6-18 months was 6.4 ± 7.0% and 6.4 ± 5.2%, for FTF clinic and phone, respectively. The cost to FTF participants was $789.58 more per person.

Conclusions: Phone delivery provided equivalent weight loss and maintenance and reduced program cost. Ubiquitous access to phones provides a vast reach for this approach.
