Generic health literacy of adolescents in Germany: Results of a nationwide cross-sectional survey

Abstract

Abstract Background For developing effective interventions to promote health literacy in adolescence, differentiated data on the distribution of health literacy levels is required, but still lacking for this age group in many countries. The study aims to measure the distribution of generic health literacy (GHL) among adolescents addressing cognitive, behavioural, communicative and motivational dimensions of GHL. Methods We conducted a representative nationwide cross-sectional online survey among 14-17-year-olds living in Germany (n = 1,235). Data on GHL were collected from 09.2019-12.2019 using the “Measurement of Health Literacy Among Adolescents”-Questionnaire (MOHLAA-Q). It was specially developed for this age-group and consists of a total of 29 items in four subscales: A: “Difficulties in Dealing with Health-Related Information”, B: “Health-Related Communication Skills”, C: “Attitudes toward One's Own Health & Health Information” and D: “Health-Related Knowledge”. We also collected data on socio-demographic factors. Bivariate and multiple logistic regression analyses were carried out. Results About half of the 14-17-year-olds reported many (8.4%) or some difficulties (42.2%) in dealing with health information. We observed low communication-related skills in 28.1% of adolescents. Regarding the attitude towards their own health and health information, 56.8% of respondents had a rather “partly passive/partly active” attitude and 8.8% had a “passive” attitude. 22.7% of the adolescents had a low level of health-related knowledge. All socio-demographic factors apart from age showed significant differences in each of the scales: by family affluence in all scales, by gender and by educational level in 3 scales and by migration background in 1 scale. Conclusions The results indicate a need for promoting GHL among adolescents. The differences in the four scales suggest that all dimensions of GHL should be addressed, but also considering socio-demographic factors at the same time.
