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 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.

child BMI z-score
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.
Time frame: 2 years

Time frame: 2 years
Child Physical Activity and Sedentariness: C-PAQ and PAQ-C
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

Child Physical Activity and Sedentariness: ActiGraph GT1M
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 BMI
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.
Time frame: 2 years
Child utilization of built environment resources
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.
