[Digital health literacy of pupils. Level and associations with physical activity and dietary behavior].

Background: While there are increasing empirical findings on general health literacy (HL), there is a lack of evidence on digital HL in adolescence and its association with health behavior.

Methods: A cross-sectional study of 490 students from grade eight and nine from the federal state of Hesse was conducted from October 2019 to February 2020. Digital HL was assessed using five subscales of the Digital Health Literacy Instrument (DHLI), while consumption of fruits, vegetables, and soft drinks as well as weekly physical activity were used as indicators of health behavior.
