Randomized Controlled Trial of Storytelling vs Didactic Education Effects on Dietary Colorectal Cancer Risk Behaviors among Latinxs

J Health Care Poor Underserved. 2021;32(3):1531-1553. doi: 10.1353/hpu.2021.0148.


Dietary patterns associated with risk for colorectal cancer (CRC) may contribute to continuing health disparities in Latinx populations. Latinx from low-income communities, aged 25-65, were randomized to a 12-week storytelling-based intervention (ST) (n = 300) or didactic learning (DL)(n = 285) classes on cancer screening and dietary changes related to CRC risk facilitated by Latinx lay health workers (promotora/es de salud). Dietary intake was assessed pre-and post-intervention (24-hour dietary recall) with no significant differences found between ST and DL groups. Specific dietary changes in both groups included increases (p<.05) in dietary fiber (ST from 17.0 to 18.2; DL from 16.38 to 17.8 gms), calcium (ST from 715.7 to 781.9; DL 666.4 to 748.7 mgs), and vegetables (ST 2.5 to 2.8; DL 2.4 to 2.6 servings/day). Although between-intervention group effects were not significant, both culturally-adapted interventions were found to change a selection of key CRC-preventive dietary behaviors.
