Objective health literacy skills among ninth graders in Finland: outcomes from a national learning assessment.

BACKGROUND: Health literacy (HL) is an important determinant for maintaining and improving health throughout the lifespan. This underlines the need to monitor HL, including among adolescents, and to understand the factors explaining HL, with a view to decreasing differences in HL. The aim of this study was to objectively measure HL, and the relationship between HL and socio-demographic factors (gender, language of instruction, pupils' educational aspirations, parents' educational background and pupils' school achievement) among pupils (n = 3652) at the end of basic education in Finland. METHODS: A nationally representative assessment, which included 55 items on HL, was conducted as a traditional paper-and-pencil test in schools. The data were analysed via descriptive statistics and a two-level hierarchical linear model to determine how the socio-demographic factors affected HL. RESULTS: The pupils' average score on the HL test items was 58.9%, indicating a satisfactory HL level. A two-level hierarchical linear model showed that the variables (gender, language of instruction, pupils' educational aspirations, parents' educational background and pupils' school achievement) predicting the HL level had statistically significant effects. CONCLUSIONS: Among ninth graders (15-16 years old), almost one third of the boys and 8% of the girls exhibited an unsatisfactory HL level. The study also confirmed the importance of school-related factors in explaining HL differences. Since low HL has been linked to several unfavourable health indicators and has been viewed as an underestimated problem in times of pandemic and other health crises, the findings suggest that the HL level of Finnish ninth graders is a clear public-health issue.

Does health literacy explain the link between structural stratifiers and adolescent health?

BACKGROUND: The concept of health literacy (HL) may help us to better understand the mechanisms leading to health disparities, and to focus on the factors that can be influenced. However, not much is yet known about how HL is related to health disparities, or whether the association exists among adolescents. The aim of the study was to examine the associations between structural stratifiers, HL and health indicators among adolescents. METHODS: The nationally representative Finnish Health Behaviour in School-aged Children survey data (n=3833) were collected from 13- and 15-year-old pupils in the spring of 2014. Pearson correlation coefficients were calculated, and separate path models were estimated for the perceived health and health behaviour measures. RESULTS: HL was found to be an independent factor explaining disparities in health. Higher HL was related to positive health outcomes. HL also acted as a mediator between health behaviours and structural stratifiers, except for gender. School achievement and educational aspirations were among the factors explaining the HL level, which in turn, explained the health indicators. CONCLUSION: The concept of HL is of use in understanding health disparities. In particular, HL provides a mechanism via which school achievement and educational plans affect health outcomes. Low HL places adolescents who have poor school achievement and who do not intend to continue on an academic path in an unequal position with respect to their health.
