The Amish have cultural practices that include formal education through the 8th grade. This study's purpose was to compare the health literacy among Amish to non-Amish adults living in Ohio Appalachia to understand its potential contribution to poorer health behaviors (e.g. lower cancer screening rates). Amish (n = 143) and non-Amish (n = 154) adults completed interviews as part of a lifestyle study. The rapid estimate of adult literacy in medicine (REALM) instrument (score range 0-66) was used and mean REALM scores were compared (t test) and correct pronunciation of each word was compared (Chi square test). Significance was considered at p < 0.001 because of multiple comparisons. Mean REALM scores among Amish males (53.3 ± 13.1) and females (56.2 ± 8.6) were significantly (p < 0.001) lower compared to non-Amish males (61.2 ± 9.8) and females (63.0 ± 6.2). Twelve percent of Amish participants read at or lower than a 6th grade level compared to 2.6 % of non-Amish participants. This study provides a glimpse into how culture may influence health literacy. Many Amish participants had limited or marginal health literacy. Innovative strategies that address inadequate health literacy and specific cultural characteristics are needed to improve health-related behaviors and outcomes among the Amish.
