Associations between health literacy proficiencies and health-related quality of life and GP visits among young people in Norway: a population-based cross-sectional study.

Abstract

Despite globally increased attention from policymakers and being recognised as a critical determinant of health, health literacy (HL) research in young people (YP) remains limited. This study aims to describe HL in YP across person factors and explore the associations between HL and health-related quality of life (HRQoL) and the number of visits to general practitioners (GP visits). Cross-sectional study. Population-based data collection applying country representative strata in Norway. 890 participants aged 16-25 years. Rasch modelling and Wright's method were used to identify statistically distinct levels of HL proficiency. Multiple linear regression and negative binomial regression models were applied to explore the associations between HL and HRQoL, and between HL and GP visits, respectively. Among YP, HL was statistically significantly associated with HRQoL and the number of GP visits, when adjusting for age, gender, education, self-perceived social status and financial deprivation. For every logit increase in HL, the number of GP visits decreased by 22%. Four statistically distinct levels of HL proficiency were identified for the 12-item HLS₁₉-YP12 scale, started from a cut-point of 23, 30, 37 and 44 out of 48. Relatedly, 70% of respondents were observed at or below level 2 (30-36 points), indicating a varying lack of central skills. The span from lowest (1) to highest (4) HL level was associated with a decrease of 2.1 GP visits per year and an increase of .12 on the EQ-5D index. This study provides new empirical insights into the impact of HL in YP. Identified cut-points for the HLS₁₉-YP12 may contribute to simplifying the process of adapting information and communication for various HL skills. The study also suggests the need for more efforts in HL policy and structural intervention development to enhance YP health and well-being.
