Brief summary
The study will test the impact of a community health worker (CHW)-delivered intervention aimed at helping families overcome barriers to childhood obesity prevention. Barriers include social, environmental, and family issues. This intervention will be compared to a control condition consisting of a community health worker (CHW)-delivered intervention aimed at helping families improve positive parenting skills.
Detailed description
The study will test the impact of a community health worker (CHW)-delivered intervention aimed at helping families overcome barriers to childhood obesity prevention. Barriers include social, environmental, and family issues. This intervention will be compared to a control condition consisting of a community health worker (CHW)-delivered intervention aimed at helping families improve positive parenting skills. The intervention uses multiple delivery modalities to maintain novelty and prevent attrition/burden. These include home visits, telephone contacts, print (literacy sensitive newsletters), social media (Facebook), and community events. Parents and children will complete scheduled assessments at baseline, 6-, 12-, 18- and 24-month follow-up. The Specific Aims are: Aim 1: To determine the effectiveness of the intervention compared to the control condition on child physical activity, healthy eating, BMI and utilization of built environment resources. Aim 2: To determine the effectiveness of the intervention compared to the control condition on parent physical activity, healthy eating, BMI. Aim 3: To examine the potential scalability of the intervention guided by the RE-AIM (Reach Effectiveness Adoption Implementation Maintenance) model.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| child BMI z-score | 2 years | Weight and height is measured using standard methodology, with children wearing light clothing and no shoes. Weight is measured to the nearest 0.5 lb on a digital scale. Height is measured to the nearest tenth of a centimeter using a stadiometer. BMI is calculated: weight (kg)/height squared (meters) for age and gender using United States Centers for Disease Control and Prevention BMI charts growth charts. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Child Dietary Behaviors for snacks | 2 years | This Outcome Measure is assessed through the following measure, modified for verbal administration:Snack items from the Beverage and Snack Questionnaire2 (BSQ2) (https://sharedresources.fredhutch.org/documents/beverage-and-snack-questionnaire-2) |
| Child Dietary Behaviors for Beverages | 2 years | This Outcome Measure is assessed through the following measure, modified for verbal administration: Beverage Intake Questionnaire (Hedrick et al) |
| Parent Dietary Behaviors: Overall | 2 years | This Outcome Measure is assessed through the following measure, modified for verbal administration: Selected items from the Massachusetts Parent Child Longitudinal Cohort Survey (Taveras et al., MA-CORD Study Group) |
| Parent Dietary Behaviors for Snacks | 2 years | This Outcome Measure is assessed through the following measure, modified for verbal administration: Snack items from the Beverage and Snack Questionnaire2 (BSQ2) (https://sharedresources.fredhutch.org/documents/beverage-and-snack-questionnaire-2) |
| Parent Dietary Behaviors for Beverages | 2 years | This Outcome Measure is assessed through the following measure, modified for verbal administration: Beverage Intake Questionnaire (Hedrick et al) |
| Child Physical Activity and Sedentariness: Massachusetts Parent Child Longitudinal Cohort Survey | 2 years | This Outcome Measure is assessed through the following measure, modified for verbal administration: Selected items from the Massachusetts Parent Child Longitudinal Cohort Survey (Taveras et al., MA-CORD Study Group) |
| Child Dietary Behaviors: Overall | 2 years | This Outcome Measure is assessed through the following measure, modified for verbal administration: Selected items from the Massachusetts Parent Child Longitudinal Cohort Survey (Taveras et al., MA-CORD Study Group) |
| Child Physical Activity and Sedentariness: ActiGraph GT1M | 2 years | Child physical activity and sedentariness are measured by the child wearing the ActiGraph Model GT1M for 7 days averaged. This measure provides data on intensity and duration of activities. |
| Parent physical activity and sedentariness: Massachusetts Parent Child Longitudinal Cohort Survey | 2 years | This Outcome Measure is assessed through the following measure, modified for verbal administration:Selected items from the Massachusetts Parent Child Longitudinal Cohort Survey (Taveras et al., MA-CORD Study Group) |
| Parent physical activity and sedentariness: C-PAQ and PAQ-C | 2 years | This Outcome Measure is assessed through the following measure, modified for verbal administration: Selected items from the Physical Activity C-PAQ (Kemper et al) plus PAQ-C (Kowalski et al) activity questions |
| Parent physical activity and sedentariness: ActiGraph GT1M | 2 years | Parent physical activity and sedentariness are measured by the parent wearing the ActiGraph Model GT1M for 7 days averaged. This measure provides data on intensity and duration of activities |
| Parent BMI | 2 years | BMI is calculated with weight and height measurements using standard methodology. Weight is measured to the nearest 0.5 lb on a digital scale. Height is measured to the nearest centimeter using a stadiometer. BMI is calculated: weight (kg)/height squared (meters) for gender using United States Centers for Disease Control and Prevention BMI charts. |
| Child utilization of built environment resources | 2 years | Child utilization of built environment resources is assessed by the children wearing a portable GPS unit (\ size of a matchbox) when wearing an accelerometer. The GPS unit records the geographic coordinates of the child's activities. Measures of frequency and duration of activities by neighborhood space (e.g., parks) can be ascertained. |
| Child Physical Activity and Sedentariness: C-PAQ and PAQ-C | 2 years | This Outcome Measure is assessed through the following measure, modified for verbal administration:Selected items from the Physical Activity C-PAQ (Kemper et al) plus PAQ-C (Kowalski et al) activity questions |
