简要总结
Examine the effect of three different dietary messages on dietary intake and the health of parents and their children.
详细描述
The goal of this pilot study is to conduct a randomized controlled trial examining three dietary messages: increase fruits and vegetables [INCREASE], decrease energy-dense, non-nutrient dense snack foods [DECREASE], or increase fruits and vegetables plus decrease snack foods [INCREASE+DECREASE], within a 6-month, family-based obesity prevention intervention. Each condition will also focus on increasing family evening meals and physical activity. Primary hypotheses are: 1) INCREASE + DECREASE will consume a greater ratio of F&Vs:SFs than INCREASE and DECREASE at 6 months.
2)INCREASE + DECREASE will consume less energy than INCREASE and DECREASE at 6 months.

研究组 & 干预措施
Increase + Decrease Condition
Families will be encouraged to increase fruits and vegetables and decrease snack foods.
干预措施: Increase Fruits and Vegetables and Decrease Snack Foods (Behavioral)
Decrease Condition
In the Decrease Snack Foods condition participants will reduce intake of SFs (i.e., candy, cookies, cakes, ice cream, chips, nuts) to < 3 servings/week (for children aged 6 to 12 years, the solid fats and added sugar energy limit is 840 kcals/week and the DECREASE goal will help with meeting this limit). Children and parents will gradually work towards meeting these goals and self-monitor these behaviors.
干预措施: Decrease Snack Foods (Behavioral)
Increase Condition
A parent and child will be encouraged to increase fruits and vegetables. Children will be encouraged to consume 1 cup/day and 1.5 cups/day of whole fruit, and 1.5 cups/day and 2 cups/day of vegetables for children aged 6 to 8 years and 9 to 12 years, respectively. Children will gradually work towards these goals. Parents will also work towards F&V goals, with 2 cups/day of whole fruit and 2.5 cups/day of vegetables.
