“…Several studies have also assessed the reliability and validity of the NVS in children and adolescents with mixed results due to inconsistencies in ages of the samples (Driessnack, Chung, Perkhounkova, & Hein, ; Howe, Van Scoyoc, Alexander, & Stevenson, ; Warsh, Chari, Badaczewski, Hossain, & Sharif, ). Because very little validity and reliability data exists on the use of the NVS in adolescents, validity and reliability of the NVS for use in adolescents with SCD was examined in the previous pilot study (Caldwell, Carter, Becker, & Mackert, ). Face validity was performed on the NVS by the PI as well as other experts in SCD and health literacy, and the instrument was deemed valid by this standard.…”

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.

“…HL was assessed using the Newest Vital Sign (NVS), a simple tool that assesses comprehension of a food label. The NVS has been well validated against well‐accepted measures of HL in adults; likewise, the NVS has been used to evaluate HL in numerous studies of adolescents and has been validated against gold‐standard tests of reading comprehension in adolescents, including adolescents with SCD . In the NVS, participants are presented with a nutrition label and are asked to answer six questions that require mathematical skills and the ability to read and make decisions based on written information.…”

Background Patients with sickle cell disease (SCD) may require chronic transfusion therapy (CTT) for prevention of stroke or other complications. Limited health literacy (HL) is common and is associated with poor health‐related knowledge and outcomes in chronic disease. We sought to assess HL and transfusion knowledge in patients with SCD on CTT and their caregivers. Methods A cross‐sectional study of patients was conducted in outpatient hematology clinics. Forty‐five pairs of adolescent patients and caregivers and 20 caregivers of pre‐adolescent patients completed the Newest Vital Sign HL assessment and answered questions assessing SCD and transfusion knowledge. Community‐level median income and unemployment rates were estimated from Census data. We computed the correlation of HL with knowledge and compared each to Census variables, payor status, educational attainment, and stroke. Results HL was inadequate in 22 (34%) caregivers and 31 (69%) adolescents. Adequate caregiver HL was associated with higher educational attainment but not community‐level socioeconomics or payor status. Mean knowledge score was lower in adolescents than in caregivers and correlated with age in adolescents (r = 0.42, P = .004). HL correlated with knowledge (r = 0.46, P < .0001). There were no significant correlations of HL or knowledge between adolescents and their caregivers. Neither HL nor knowledge was associated with prior stroke. The greatest knowledge was demonstrated for iron overload and SCD genotype, whereas knowledge gaps existed in alloimmunization, indication for CTT, and SCD curative therapy. Conclusions Enhanced educational resources in transfusion therapy, alloimmunization, and curative therapy are needed for patients with SCD and caregivers of all HL levels.

“…Newest Vital Sign (NVS) is a quick and accurate screening test for limited HL. NVS was chosen because it was not only reliable in primary health care setting for adults, but also among adolescence population (Caldwell, Carter, Becker, & Mackert, 2018). The NVS evaluated both literacy and numeracy (the ability to understand and work with numbers) as well as the ability to locate and apply information.…”

Background. The aim of the study was to identify links between health literacy, health information literacy and physical activity as well as body mass index in adolescents.Methods. The study was carried out from September till the end of November, 2018. Research participants were 167 14–18-year-old students from Kaunas, Klaipeda and Vilnius (n = 107 females, n = 60 males). Participants were asked to fill in an anonymous online questionnaire, which consisted of basic demographics, physical activity, health information literacy and health literacy. Adolescents’ body mass index was calculated using ISO-BMI calculations. Physical activity was assessed by Petronytė’s physical activity questionnaire. To determine adolescents’ everyday health information literacy, we used self-assessed 10-item screening tool (EHIL-10) and to determine health literacy, we used Newest Vital Sign (NVS) screening test. Data analysis was performed using SPSS 23.0 program for Windows.Results. Health literacy did not have association with body mass index or the level of physical activity. Health literacy scores gave important data of the level of health literacy. The scores indicated that 21.6% of Lithuanian adolescents had adequate level of health literacy. It was found that age correlated positively with health literacy. Self-assessed everyday health information literacy was higher since 85% of the students had medium high or high level of health information literacy. The data revealed that adolescents were not sure where they could find health related information and who they could trust in health-related issues. For males, finding health information and knowing who they could trust in health issues was easier than for females. Health information literacy did not have association with ISO-BMI. Sufficient evaluation of health-related information was higher among normally weighted adolescents. Physically active students had higher health information literacy and participation in sports club activities had positive relation with better health information literacy. Additionally, involvement in organized activities associated with superior understanding of terms and sentences of health information. Evaluation of health information was higher among those who were actively involved in organized physical activities.Conclusions. Health information literacy did not have association with ISO-BMI. Those, who were involved in sports club activities or were more actively involved in organized physical activities had better health information literacy and evaluation of health information. Nevertheless, there was no connection between health literacy and physical activity. Keywords: health literacy, health information literacy, physical activity, body mass index.
