Lifestyle modifications involving diet and exercise are effective in reducing the incidence of type 2 diabetes (1–3). In particular, lifestyle changes targeted toward increasing daily energy expenditure are a cornerstone treatment of type 2 diabetes (2). In the Diabetes Prevention Research Group study (4), a goal of 150 min/week of physical activity was recommended, and 74% of the patients in this study group achieved this level by 24 weeks. This type of success in exercise modification is made possible in research protocols by intensive individual counseling (5), which may not be easily reproduced in primary care settings. Because of the critical importance of increasing daily energy expenditure and its central role in preventing and/or treating diabetes, one can surmise that instrumentation providing accurate and simple feedback to type 2 patients may have clinical utility.
Therefore, we provide preliminary data on the accuracy of the HealthWear Armband (Roche Diagnostics, Indianapolis, IN), an instrument designed …
