      ab: Purpose: To examine the association of health literacy (HL) with changes in health-related quality of life (HRQL) among patients with type 2 diabetes.Methods: Data from a cohort study of type 2 diabetes patients were used. HL was assessed using 3 previously validated screening questions and HRQL using the EQ-5D-5L and SF-12 [physical and mental composite summary scores (PCS, MCS)]. The associations of baseline HL with changes in EQ-5D, PCS, and MCS scores over 1 year and with directions of changes (no change; declined; improved) were examined. Missing data were handled with multiple imputation and sensitivity analyses.Results: Average age of participants (N = 1948) was 64.6 ± 10.9 years, 45 % were female, and 12.6 % had inadequate HL. Participants had mean decrements of 0.01 in EQ-5D, 1.0 in PCS, and 1.2 in MCS over 1 year. In adjusted analysis, HL was not associated with changes in EQ-5D over 1 year (β = 0.01, P = 0.146); however, patients with adequate HL had 2.1 points greater increase in PCS (P < 0.001) and 3.1 points in MCS (P < 0.001) compared to those with inadequate HL. Patients with adequate HL were less likely to have a decline in EQ-5D (RR 0.66; 95 % CI 0.44, 0.98), PCS (RR 0.51; 95 % CI 0.34, 0.76), and MCS (RR 0.49; 95 % CI 0.33, 0.72) compared to those with inadequate HL. Patients with adequate HL were more likely to have an improvement in MCS compared to those with inadequate HL (RR 1.78; 95 % CI 1.04, 3.04); such associations were not observed for PCS or EQ-5D. All results were robust in sensitivity analyses.Conclusions: Inadequate HL was independently associated with worsening HRQL in adults with type 2 diabetes, particularly in the mental health domain.
