A systematic review of postpartum physical activity intervention mediators.
Bibliographic record
Abstract
OBJECTIVE: Regular physical activity (PA) is associated with many health benefits; however, up to 94% of postpartum individuals do not meet PA guidelines. Understanding mediators of postpartum PA behavior change interventions is essential to increase PA participation following childbirth. The purpose of this review was to identify putative mediators of postpartum PA interventions. METHOD: Six databases were searched for primary or gray literature from inception until December 2023. Intervention studies of any language were included if they contained (a) individuals ≤ 12 months postpartum, (b) a PA intervention, (c) a no exercise or different exercise comparator, and (d) a change in PA and putative mediator outcome that could be classified with the theoretical domains framework (TDF). Results were categorized by mediation path, mediator TDF domain, and PA outcome. RESULTS: = .12) of postpartum PA interventions on PA. CONCLUSION: Future postpartum PA interventions should integrate components that increase outcomes under the domains of beliefs about capabilities, beliefs about consequences, environmental context and resources, and social influences. Further research that tests nonconscious mediators (e.g., PA habit, identity) is needed. (PsycInfo Database Record (c) 2025 APA, all rights reserved).

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
