Child Obesity
Conditions
Brief summary
This study will examine the mediator/moderator variables that affect efficacy of a parent stress intervention with nutrition education (PMH+N: parenting mindfully for health) vs. Control intervention with nutrition education (CTL+N) on parent stress, parenting, health behaviors and child obesity risk. A non-randomized historical control group will also be assessed during the intervention and follow-up periods throughout to obtain outcome assessment without any interventions being provided.
Detailed description
This is a 5-year interdisciplinary project to assess a 12-week Parenting Mindfully for Health (PMH) + nutrition counseling (N) versus contact control intervention (C) + nutrition counseling (N), to examine short-term and long term enduring effects of PMH+N to promote healthy eating and physical activity in parent and child, and prevent childhood obesity risk in 2-5 year olds, via changes in parent stress and parenting. A non-randomized historical control group will also be assessed during the intervention and follow-up periods throughout to obtain outcome assessment without any interventions being provided.
Interventions
BEHAVIORALParenting Mindfully for Health Nutrition (PMH)
PMH will include included the following components: 1. mindfulness strategies as outlined in the MBSR manual, 2. mindful parenting concepts, 3. mindful eating and awareness of family choices; 4. self and child monitoring of food intake, PA and emotional reactivity; 5. utilizing mindfulness for emotion regulation and distress tolerance, 6. behavioral strategies of goal setting and implementing increasing frequency of healthy food intake and physical activity (PA)
BEHAVIORALContact Control Nutrition (C+N)
Contact Control Group where parents engage in a quiet, relaxing, but stimulating activity and also nutrition counseling.
OTHERNon-randomized historical control (WLC) assessment only
Non-randomized, historical control group with only assessments during intervention and follow-up period.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Parenting Behavior Change | TWT parenting behavior ratings at Baseline Pre-intervention and at post-intervention (week 12) | Observed parenting behavior ratings for increase in positive parenting behaviors in the Toy Wait Task (TWT) |
| Parent Stress change from Pre to Post intervention | Baseline Pre-intervention to Post intervention at 12 weeks | Parent stress measured by the Perceived Stress Scale scores ranging from 0-56 with higher scores indicating more stress. |
| Child BMI change post intervention and at short term 6 month follow-up | Change from Pre-intervention to post-intervention (week 12) and at 6 month short term follow up | Child height will be measured with a measuring tape. For children, weight and height will be plotted on the CDC growth chart for the child's age to determine the BMI-for-age percentile scores. |
| Child food intake change | Baseline Pre-intervention and at post-intervention (week 12) | Parent report of child food frequency questionnaire assessment of frequency of healthy and unhealthy food intake. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Parenting Stress Inventory (PSI) | PSI scores at Baseline Pre-intervention and at post-intervention (week 12) and at follow-ups months 6-, 12-, 18- and 24 month timepoints | Parent reported PSI scores ranging from 18-90 with higher scores indicating higher parenting stress. |
| Parent Stress change from Post intervention to follow up period over 24-months | Post intervention at 12 weeks to follow-up timepoints at 6-, 12-, 18- and 24- month timepoints | Parent stress measured by the Perceived Stress Scale scores ranging from 0-56 with higher scores indicating more stress. |
| Child BMI change at long term term follow-up | Baseline compared to 12-month, 18-month and 24-month timepoint | Child height will be measured with a measuring tape. For children, weight and height will be plotted on the CDC growth chart for the child's age to determine the BMI-for-age percentile scores. |
| Child food intake change | Baseline Pre-intervention and at post-intervention (week 12) | Parent report of child food frequency questionnaire assessment of frequency of healthy and unhealthy food intake. |
Other
| Measure | Time frame | Description |
|---|---|---|
| Parent BMI | baseline | Parent height will be measured with a stadiometer, and parent BMI will be calculated from weight and height. For parents, waist circumference (WC) and percent body fat will also be measured using the TANITA and following the well-established NHBLI and NHANES III protocol. |
