Randomized Controlled Trial
Health Literacy, Numeracy, and Health Promotion: A Secondary Analysis of the Choosewell 365 Workplace Trial.
Health literacy and numeracy are linked to obesity and dietary behaviors. This study investigates whether the effect of a workplace behavioral intervention to prevent weight gain and improve diet differed by employee health literacy and numeracy. ⋯ A behavioral intervention improved cafeteria food choices of hospital employees of varying health literacy and numeracy levels and improved diet quality among employees with lower health literacy, suggesting this group also improved food choices outside of work.
