SMART: A Social and Mobile Weight Control Program for Young Adults

The focus of the SMART study is to develop an intervention to prevent weight gain in young
adults at risk for weight gain and promote weight loss in overweight or obese young adults.
The investigators will recruit college and university students to evaluate the effects of
SMART on weight status and other metabolic, behavioral and psychosocial outcomes up to and
including 24 months.

The Primary aim of the study is to evaluate between condition differences in weight status
at 24 months.

Secondary aims will assess the impact of the SMART intervention on: Diet, physical activity,
sedentary behaviors, quality of life and depression at 6, 12, 18 and 24 months;
Anthropometric measures (BP, waist circumference) at 6, 12, 18 and 24 months; Differences in
weight status at 6, 12 and 18 months; Level of satisfaction and amount of use of the
intervention components.

These aims will be applied to both normal weight and overweight/obese young adults. Among
normal weight young adults, the investigators will determine whether SMART increases
adoption of healthy dietary and PA behaviors and prevents weight gain. Among
overweight/obese young adults, the investigators will determine whether SMART produces
weight loss.
