Brief Summary:
Investigators are conducting a randomized controlled trial with overweight and obese college students on the University of Minnesota campus. The primary outcome will be weight loss measured 12 months after study enrollment (corresponds to 10 months after the end of treatment).

Condition or disease Intervention/treatment Phase
Overweight Obese Behavioral: Bi-weekly in person meetings with a Registered Dietician Behavioral: Financial incentives for weight loss maintenance Not Applicable

Detailed Description:

Approximately 30% of college students are overweight or obese. Intervening on excess weight early may eliminate obesity-related morbidity. Evidence supports use of monetary incentives to encourage weight-loss; questions remain about the efficacy of contingency management on weight loss maintenance.

"Lose 2 Win" contests in which participants who achieve weight-loss goals are eligible for cash prizes, appear well-suited for implementation on campuses. Our objective in this two-phase trial is to evaluate the feasibility, acceptability and efficacy of Lose 2 Win for weight-loss maintenance among college students.

Arm Intervention/treatment
Experimental: Contest Plus
The Contest Plus group were eligible to receive the financial incentives for weight loss maintenance at three monthly follow ups; weeks 16, 20 and 24. Eligible participants completed online surveys and in person weigh ins verifying weight maintenance. In addition to the financial incentives, participants in this group had bi-weekly in person meetings with a Registered Dietician during phase 2 (week 16-24) of the trial. They also received an in home scale to monitor weight daily.
Behavioral: Bi-weekly in person meetings with a Registered Dietician

Participants in the Contest Plus group had the opportunity to receive 5 in person meetings with a Registered Dietician. These meetings took place bi-weekly and gave the participants a chance to discuss food consumption, physical activity, meal planning and assessed the participant's weight at each visit.

Participants in the Contest only and Control group were not eligible to receive these meetings.


Behavioral: Financial incentives for weight loss maintenance
Participants in the Contest Plus and Contest Only groups were eligible for a lottery based financial incentive for maintaining their weight lost during phase 1 (Baseline to week 10) of the trial. There were three, month-long follow up assessments (weeks 16, 20 and 24) that participants were eligible for. The lottery prize was contingent upon the length of time they maintained their weight loss.

No Intervention: Control
The Control condition did not receive any intervention and were not eligible to win the lottery based incentive. Participants completed follow surveys (weeks 16, 20 and 24) and received remuneration for completing surveys and in person weigh in.
Experimental: Contest Only
The Contest only group were eligible to receive the financial incentives for weight loss maintenance for maintaining weight lost at three monthly follow ups; weeks 16, 20 and 24. Eligible participants completed online surveys and in person weigh ins verifying weight maintenance.
Behavioral: Financial incentives for weight loss maintenance
Participants in the Contest Plus and Contest Only groups were eligible for a lottery based financial incentive for maintaining their weight lost during phase 1 (Baseline to week 10) of the trial. There were three, month-long follow up assessments (weeks 16, 20 and 24) that participants were eligible for. The lottery prize was contingent upon the length of time they maintained their weight loss.




Primary Outcome Measures :
  1. Maintenance of the weight lost from Baseline to Week 10 (Phase 1) measured ten months (week 52) after end of treatment (week 10). [ Time Frame: Baseline, Week 10, Week 24, Week 52 ]

Secondary Outcome Measures :
  1. Change in physical activity from baseline on the Physical Activity Questionnaire at week 24 [ Time Frame: Baseline, Week 24 ]
  2. Change in physical activity from baseline on the Physical Activity Questionnaire at week 52 [ Time Frame: Baseline, Week 52 ]
  3. Change in nutritional quality of diet from baseline on the Block Food Questionnaire at week 24 [ Time Frame: Baseline, Week 24 ]
  4. Change in nutritional quality of diet from baseline on the Block Food Questionnaire at week 52 [ Time Frame: Baseline, Week 52 ]
