A community feasibility study of a cooking behavior intervention in African-American adults at risk for cardiovascular disease: DC COOKS (DC Community Organizing for Optimal culinary Knowledge Study) with Heart

Key Result

This paper describes the protocol for a feasibility study of a 6-week community-based cooking intervention among African-American adults at risk for cardiovascular disease; no results are reported.

Structured PICO

Does a 6-week community-based cooking intervention demonstrate feasibility and improve cooking behaviors in African-American adults at risk for cardiovascular disease?

Population

50 African-American adults at risk for cardiovascular disease living in a food desert in Washington, D.C., enrolled in a two-phase feasibility study of a 6-week community cooking intervention.

Intervention

6-week community-based cooking intervention (weekly 90-min sessions) led by a chef using the 'Health meets Food' Mediterranean diet curriculum.

Outcome

Phase 1: acceptability and facilitators/barriers to cooking. Phase 2: feasibility of the intervention (demand, adherence, acceptability, practicality, integration).

This study protocol describes a community-based feasibility trial of a 6-week culinary medicine intervention to improve dietary behaviors and cardiovascular risk factors among African-American adults in an urban food desert.

Limitations

Study protocol only, no clinical results available yet

Abstract

BACKGROUND: Cooking interventions have increased in popularity in recent years. Evaluation by meta-analyses and systematic reviews show consistent changes in dietary quality reports and cooking confidence, but not of cardiovascular (CVD) biomarkers. Interventions evaluating or reporting behavioral mechanisms as an explanatory factor for these outcomes has been sparse. Moreover, evaluations of cooking interventions among communities with health disparities or food access limitations have received little attention in the literature. METHODS: This study will occur over two phases. Phase 1 will assess acceptability among the target population of African-American adults living within an urban food desert. Phase 2 will consist of a 6-week cooking intervention delivered at a community kitchen setting. Pre and post intervention visits for clinical examinations and biomarker collection will be conducted, as well as dietary and cooking skill assessments. Primary outcomes include cooking behavior and feasibility measures. Secondary outcomes are related to dietary quality, psychosocial factors, CVD biomarkers, and food environment measures. DISCUSSION: This study seeks to demonstrate feasibility of a community-based cooking intervention and to provide necessary information to plan future interventions that identify cooking behavior as an outcome of participation in cooking interventions among African-American adults, especially in relation to dietary and biomarker outcomes. TRIAL REGISTRATION: This study was registered at ClinicalTrials.gov (NCT04305431) on March 12, 2020.
