This cross-sectional survey of 19,231 individuals in Denmark found that higher digital health literacy was positively associated with higher physical activity levels, even after full adjustment for covariates. No significant interaction was found for long-term health conditions, though individuals with more conditions exhibited the lowest digital health literacy scores.
The survey measured digital health literacy using three eHLQ scales and physical activity levels. Logistic regression assessed associations, with Model 2 fully adjusted for age, sex, ethnicity, BMI, marital status, educational level, and work status. Positive associations were found between higher digital health literacy and all three physical activity outcomes, with the strongest associations for self-reported physical activity (eHLQ 5: OR 1.54, p < 0.001). No significant interaction was found between long-term health conditions and the association between digital health literacy and physical activity, though individuals with three or more body systems with long-term conditions had the lowest digital health literacy scores. Limitations include the cross-sectional design precluding causal inference, potential self-report bias, restriction to one Danish region limiting generalizability, use of only three eHLQ scales, and unmeasured confounders such as access and motivation.
