The Effect of Three Different Dietary Messages on Dietary Intake and Health in Families

Study Overview
=================
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.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Decrease Condition<br>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. | Behavioral: Decrease Snack Foods<br>* 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.<br>|
| Experimental: Increase + Decrease Condition<br>Families will be encouraged to increase fruits and vegetables and decrease snack foods. | Behavioral: Increase Fruits and Vegetables and Decrease Snack Foods<br>* Will combine the goals of the increase and decrease conditions.<br>|
| Experimental: Increase Condition<br>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. | Behavioral: Increase Fruits and Vegetables<br>* 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.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in Dietary intake | 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). | baseline and 6 months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in Anthropometrics | child and parent height, weight, BMI, and z-BMI | baseline and 6 months | 
| Change in Parent Feeding Styles | Includes 7 topics: perceived responsibility, perceived parent weight, perceived child weight, concern about child weight, restriction, pressure to eat, and monitoring. | baseline and 6 months | 
| Change in Parenting Styles | Assesses practices associated with different parenting styles | baseline and 6 months | 
| Change in Eating Pathology | Kids eating disorder survey and eating in the absence of hunger survey | baseline and 6 months | 
| Change in Physical Activity | Previous day physical activity recall- looks at 2 weekdays and 1 weekend day. For parents and children to complete | baseline and 6 months | 
| Change in Obesogenic Home Food Availability | self-report on foods that are available in the home. | baseline and 6 months |
