Brief Summary

The BHCK study will develop, implement, and evaluate a community-based obesity prevention program, which operates at multiple levels of an urban food system (policy, wholesaler, corner stores, carryout, household, individual; in Baltimore, MD), and will improve the healthy food supply chain to increase affordability, availability, purchasing and consumption of healthy foods within low-income, minority neighborhoods.

Detailed Description

Our overarching goal is to develop and evaluate a community-based obesity prevention program, which operates at multiple levels of an urban food system (policy, wholesaler, corner stores, carryout, household, individual; in Baltimore, MD), and will improve the healthy food supply chain to increase affordability, availability, purchasing and consumption of healthy foods within low-income minority neighborhoods. Our research will include stakeholders/ partners at different levels, e.g., the policy, wholesaler, retailer, adult caregiver, and individual child levels, and then develop, implement, and assess a two year multi-level systems-based child obesity prevention strategy targeting minority and low-income children (predominantly AA). Thirty low-income, predominantly AA geographic zones will be identified ("healthy eating zones"). Half of these zones will be randomized to intervention, while the other half will be control. Within each intervention zone we will work with 3-5 small food stores and prepared food sources to increase access to healthy foods through wholesaler discounts, display point of purchase promotional materials, and provide nutrition and food preparation education targeting youth and caregivers. We will work with local policymakers to institutionalize and sustain these changes.

The project will evaluate the impact of the program on: a) healthy food pricing and availability, b) low income African American adult food purchasing and preparation, and c) low-income African American youth diet, and associated psychosocial factors.

Study Groups

Intervention

The intervention is a multi-level, multi-component intervention designed to increase access to and consumption of healthier foods in low-income, urban, minority neighborhoods. Intervention components will occur at the policy level; food wholesaler level; small food retail outlet level; neighborhood level; household level.

Group Type: EXPERIMENTAL

Intervention

Intervention Type: BEHAVIORAL

Intervention components will occur at the policy level (working within Baltimore City policy makers to sustain intervention components, and develop virtual simulations of the Baltimore food environment); food wholesaler level (working with wholesalers to stock healthier food items and provide pricing incentives to storeowners on healthier foods); small food retail outlet level (working with corner store and carry-out owners to stock, promote, and sell healthier foods and beverages); neighborhood level (working with Baltimore college students to deliver nutrition intervention sessions to younger youth in recreation centers in intervention neighborhoods); household level (providing a text messaging and social media program that provides parents and caregivers tips for healthier eating in their respective neighborhoods).

Control

Similar to many community- based public health research programs, the control arm will not receive any intervention components during the initial intervention period. However, after all assessments are completed they will receive a 'delayed intervention' protocol, where the community receives the intervention elements as described in the intervention arm after assessment measures have been completed.

Group Type: NO_INTERVENTION

No interventions assigned to this group
