Methods
The Diet, Exercise, and Weight Loss Intervention Trial (DEW-IT)
was a single-center, parallel arm trial, in which participants were
randomized to a comprehensive “lifestyle” intervention or a control
group for 9 weeks. The comprehensive lifestyle intervention was
designed to accomplish each of the JNC-VI lifestyle recommendations,
namely, consumption of the DASH diet, a reduced sodiumintake of 100 mmol/d, weight loss, and regular aerobic exercise. To
attain these goals, participants in the lifestyle group were provided
with all of their food for 9 weeks. They also exercised in a supervised
setting. Participants in the control group received no active intervention
until after the end of data collection. Outcomes were ascertained
in a blinded fashion.
