Purpose: After patients with sickle cell disease (SCD) transfer from pediatric care to adult care, significant morbidity and mortality occurs. There are many possible contributors to the success or failure of this transition. One hypothesis is that health literacy influences this transition from pediatric to adult health care. The purpose of this study was twofold: (a) to examine the relationship between caregiver and adolescent health literacy levels in adolescents with SCD; and (b) to further describe individual traits contributing to health literacy levels in adolescents with SCD as described by pilot data.
Design and methods: This cross-sectional, descriptive correlational study included the administration of the newest vital sign (NVS) health literacy instrument to 59 dyads of adolescent patients with SCD and their caregivers in a large, tertiary care center in Dallas, Texas. Convenience sampling was utilized for recruitment. Caregiver health literacy levels, age, current grade level, annual household income, caregiver education level, number of annual healthcare encounters, and adolescent health literacy levels were correlated to determine relationships amongst variables.
Results: There was no significant relationship between caregiver and adolescent health literacy levels in this population. Adolescent health literacy NVS scores were positively correlated with adolescent age, r(58) = .468, p < .001, caregiver income, r(46) = .293, p = .023, and caregiver highest education level, r(56) = .318, p = .008. Only adolescent age was a significant predictor of adolescent health literacy NVS scores, β = .485 (standard error [SE] = .109), p = .001. None of the other predictors in the model were significant, including the relationship between caregiver and adolescent health literacy NVS scores, β = .065 (SE = .131), p = .633. In addition, although caregiver income and highest education level were positively correlated with adolescent health literacy NVS scores in the bivariate analysis, these relationships were nonsignificant while controlling for each other, adolescent age, and the other variables in the model.
Practice implications: This study gives insight on potential practice and research initiatives to evaluate the health literacy of adolescents, with and without SCD, both now and in the future.
