RESULTS
Forty-one subjects were enrolled in the cross-sectional
study, 22 (53.7%) also provided data for the prospective
cohort study (Figure 1). The median age was 53.5 (interquartile
range (IQR):47, 61.5) years. Sixty-three percent
were male and 75% were African-American. Individuals
enrolled in the cohort study had higher health literacy
based on the STOFHLA as a continuous [33.8 (SD 2.3)
versus 27.3 (SD 9.6); p50.009] or categorical tool
(p50.04) as compared to individuals who did not enroll
in the cohort study (Table 1). Individuals enrolled in the
cohort study had greater diabetes numeracy [0.71 (SD
0.26) versus 0.55(SD 0.32) p50.02]. However, the other
measures of literacy as determined by diabetes literacy
(p50.58) or diabetes self-efficacy (p50.29) did not statistically
vary between groups (Table 1). Although for each
assessment, the direction was consistent with higher literacy
for subjects enrolled in the cohort study. Literacy
measures did not vary by age or gender (all p-values
>0.60).
