Brief summary
Examine the effect of three different dietary messages on dietary intake and the health of parents and their children.
Detailed description
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.
Interventions
BEHAVIORALIncrease 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. Both parent and child will self-monitor these behaviors. As one barrier to consuming F\&Vs is perceived cost of these foods, information regarding lower-cost options for F\&Vs will be included in the manual.
BEHAVIORALDecrease Snack Foods
This condition 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.
BEHAVIORALIncrease Fruits and Vegetables and Decrease Snack Foods
Will combine the goals of the increase and decrease conditions.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in Dietary intake | baseline and 6 months | Changes in F\&Vs, SFs, energy density, overall energy, and percent energy from fat intake, will be assessed by a three-day food record (two weekdays, one weekend day). |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change in Anthropometrics | baseline and 6 months | child and parent height, weight, BMI, and z-BMI |
| Change in Parent Feeding Styles | baseline and 6 months | Includes 7 topics: perceived responsibility, perceived parent weight, perceived child weight, concern about child weight, restriction, pressure to eat, and monitoring. |
| Change in Parenting Styles | baseline and 6 months | Assesses practices associated with different parenting styles |
| Change in Eating Pathology | baseline and 6 months | Kids eating disorder survey and eating in the absence of hunger survey |
| Change in Physical Activity | baseline and 6 months | Previous day physical activity recall- looks at 2 weekdays and 1 weekend day. For parents and children to complete |
| Change in Obesogenic Home Food Availability | baseline and 6 months | self-report on foods that are available in the home. |
