The impact of generative AI health knowledge acquisition on adolescents' physical activity: the mediating role of exercise self-efficacy and the moderating effect of health information literacy.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: This study investigates the impact of generative artificial intelligence health knowledge acquisition (GAI-HKA) on adolescents' physical activity (PA), with a focus on the mediating role of exercise self-efficacy (ESE) and the moderating role of health information literacy (HIL). Methods: Using stratified cluster random sampling, a total of 2,306 valid questionnaires were collected from 10 secondary schools across five cities in southern China. Data were obtained using the self-developed Generative AI Health Knowledge Acquisition Scale, the Adolescent Exercise Self-Efficacy Scale, the Health Information Literacy Scale, and Liang's revised Physical Activity Rating Scale. Structural equation modelling with PROCESS v3.5 macro (5,000 bootstraps) was employed to test direct, mediating, and moderating effects. Results: GAI-HKA was significantly and positively associated with adolescents' PA ( Conclusion: GAI-HKA directly enhances adolescents' PA and indirectly promotes exercise behavior through strengthening ESE. Moreover, higher HIL amplifies the positive effect of AI-based health knowledge on ESE. These findings suggest that schools and families should integrate efforts to cultivate adolescents' information literacy and efficacy beliefs when promoting AI-based health interventions, thereby maximizing the benefits of digital technologies in fostering youth physical activity.
