The impact of an AIPER on health behavior improvement among sedentary adults: a longitudinal extension of the TAM.
Article in Frontiers in psychology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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: Sedentary behavior has become a major public health concern and is closely associated with various unhealthy behaviors and chronic diseases. Artificial intelligence shows promise for promoting health behavior change through personalized exercise interventions. Objective: To examine, over a 6-month period, the effect of an AI-based Personalized Exercise Recommendation System (AIPER) on Health Behavior Improvement (HBI) among sedentary adults and to analyze its psychological mechanisms. Methods: A two-wave survey (T1 and T2, 6 months apart) was conducted with 492 sedentary participants. Measures covered TAM-related behavioral variables-Perceived Ease of Use (PEOU), Perceived Usefulness (PU), Attitude Toward Use (ATU), Behavioral Intention (BI), and System Use (SU)-as well as Health Self-Efficacy (HSE), Health Behavior Improvement (HBI), and demographics. Factor analyses, correlation analyses, and structural equation modeling were performed using SPSS 23.0 and Amos 23.0. Results: AIPER significantly promoted HBI among sedentary adults. Chain mediation effects were identified, whereby PEOU and PU influenced ATU and BI, and together with HSE indirectly affected SU, ultimately improving HBI. Conclusion: AIPER can increase SU and indirectly improve HBI in sedentary populations. It is recommended that government agencies, enterprises, and universities/research institutes implement AI health-management systems, formulate individualized and scientifically grounded behavior-change plans, enhance the health behaviors of sedentary groups, and advance personalized, evidence-based, and sustainable public health promotion.
