Does Mindfulness Enhance BMI in Obese Adolescents Enrolled in the Bright Bodies Weight Management Program?
Study Details
Study Description
Brief Summary
Participants will be randomized to an evidence-based healthy lifestyle program alone or a healthy lifestyle program with mindfulness meditation added. The purpose of the study will be to determine if mindfulness improves BMI outcomes more than the program alone due to the stress-reduction benefits of mindfulness.

Detailed Description
The study will randomize 44 adolescents (aged 11-17 yo) with BMI >95th percentile to traditional Bright Bodies Healthy Lifestyle Program or Lifestyle Program plus mindfulness meditation (6 sessions within the 12-week program) (22 per group). The traditional program includes exercise two evenings per week and nutrition/behavior modification one evening per week for 12 weeks. Mindfulness session topics include breathing meditation, body scan meditation, mindful eating techniques, and identification of hunger verses satiation. The primary outcome measure with be (1) BMI, while secondary outcomes include changes in (2) percent body fat, (3) perceived stress scale (questionnaire), (4) physical stress (saliva cortisol levels), and (5) overall caloric intake (pre and post food records). After the 3 month intervention, participants will engage in post measures and be asked to return 6 months later (9 months) for longer-term follow-up measures.

Outcome Measures
Primary Outcome Measures
- Body Mass Index (BMI) [Change from baseline at 12 weeks]
Body Mass Index (BMI) will be calculated using the standard formula from participants' height and weight. BMI = (Weight in Pounds / (Height in inches x Height in inches)) x 703
- Body Mass Index (BMI) [Change from baseline at 9 months]
Body Mass Index (BMI) will be calculated using the standard formula from participants' height and weight. BMI = (Weight in Pounds / (Height in inches x Height in inches)) x 703
Secondary Outcome Measures
- Percent Body Fat [Change from baseline at 12 weeks]
Tanita Body Fat Analyzer uses a foot-to-foot bioelectrical impedence to capture participant's percent body fat.
- Percent Body Fat [Change from baseline at 9 months]
Tanita Body Fat Analyzer uses a foot-to-foot bioelectrical impedence to capture participant's percent body fat.
- Perceived Stress Scale [Change from baseline at 12 weeks]
The Perceived Stress Scale is the most widely used psychological instrument for measuring the perception of stress. It is a 10-item likert questionnaire published by Mind Garden that asks about feelings and thoughts during the last month. PSS scores are obtained by reversing responses (i.e., 0=4) for positively stated items and leaving score as is for negatively stated items. An average score for this age group is 14.2, with higher scores indicating more stress. Our hypothesis is a greater change (lower scores at post) in the mindfulness group + traditional than traditional group alone.

- Physical Stress [Change from baseline at 12 weeks]
A physical indicator of stress is measured by saliva cortisol. We are using saliva swabs by Salimetrics. A normal range for saliva cortisol is 0.007-0.115 mcg/dL. Our hypothesis is a greater change (lowered) in the mindfulness + traditional group than the traditional group alone.

- Caloric Intake [Change from baseline at 12 weeks]
Calories, fat (grams), and added sugar (grams) will be measured by a 3-day food record entered into our Nutrition Data Software for Research (NDSR) Program. We will measure change and our hypothesis is that kcal, fat, and added sugar will be lower in the mindfulness + traditional group than the traditional group alone.
