Effect of a Plant-based Intervention Among Black Individuals in the Deep South: A Pilot Study

Published:November 02, 2022DOI:https://doi.org/10.1016/j.jneb.2022.08.013

      Abstract

      Objective

      To explore the feasibility, acceptability, and clinical/behavioral outcomes of a remotely-delivered, culturally-tailored plant-based nutrition and lifestyle intervention designed to improve cardiovascular risk among Black adults in a rural, Black Belt community.

      Methods

      We implemented a 12-week intervention with weekly educational sessions, cooking lessons, social support, exercise, and food items.

      Outcome(s)

      Body mass index, waist circumference, total cholesterol, low-density lipoprotein, high-density lipoprotein, high-sensitivity C-reactive protein, trimethylamine N-oxide, diet/physical activity. Paired t tests analyzed preintervention and postintervention differences (n = 24).

      Results

      Body mass index and waist circumference were reduced (P < 0.001), and total and low-density lipoprotein cholesterol decreased by 10.8% and 13.9%, respectively (P < 0.05). There was a 25.8% reduction in high-sensitivity C-reactive protein (P = 0.02). Diet and physical activity were also improved.

      Conclusions and Implications

      This pilot study demonstrated the feasibility and acceptability of a remotely-delivered intervention focused on improving cardiovascular risk through plant-based nutrition, physical activity/wellness, social support, and cultural adaptability. Larger scale and longer-term studies are needed.
