简要总结
- Does a joint parent-child dieting approach, as opposed to an individually-based approach, improve weight loss outcomes?
- Is a diet which includes Medifast meal replacements as efficacious as a non-supplemented Food Guide Pyramid-based diet (reference diet) in achieving better adherence to the diet, initial weight loss, reduction in % body fat, and weight maintenance?
- Does regular use of Medifast meal replacements, in conjunction with a Food Guide Pyramid-based diet, result in significantly better compliance, greater dietary satisfaction, dietary quality, and palatability than the reference diet?
- Do children who have lost weight using Medifast meal replacements, as an adjunct to a Food Guide Pyramid-based diet, achieve health benefits compared to baseline values and are these health benefits greater than those obtained following the reference diet?
详细描述
Weight Loss Phase: This phase will take place between week 0 and week 26 (6 months). Participants will be randomly assigned to one of two weight loss treatment groups:
- Medifast meal replacement diet group (3 supplements per day) plus food-based diet
- Reference diet group (Food Guide Pyramid-based diet)
Participants will be further randomly assigned to one of two parent-child approaches:
- Dieting child with one dieting parent
- Dieting child without dieting parent Although it is encouraged to have both parents involved in the child's care, only one parent will be permitted to be dieting as a part of the study along with the child so that we can more cleanly assess the effects of a parent dieting without confounding effects of some families having two parents dieting. Both groups will attend separate biweekly educational lessons during the weight loss phase (same curriculum and teacher). Data collection visits will occur at baseline, week 12, and transition. There are a total of 31 visits for a child participating in this study, and 30.for a parent participating by dieting with their child.
Transition Phase: Transition to a maintenance diet will be individually timed by participant attainment of goal "healthy" weight (BMI≤ 25) or week 26, whichever comes first.
