Increasing Physical Activity in Black Women: Results from a Randomized Trial Conducted in Faith-Based Settings
Bibliographic record
Abstract
<p><strong>Objective: </strong>The Learning and Developing Individual Exercise Skills (L.A.D.I.E.S.) for a Better Life study compared a faith-integrated (FI) and a secular (SEC) intervention for increasing physical activity with a self-guided (SG) control group among African American women. <strong></strong></p><p><strong>Design/Setting/Participants: </strong>L.A.D.I.E.S. was a cluster randomized, controlled trial. Churches (n=31) were randomized and women within each church (n=12 – 15) received the same intervention. <strong></strong></p><p><strong>Interventions: </strong>FI and SEC participants received 24 group-based sessions, delivered over 10 months. SG participants received printed materials to review independently for 10 months. Participants were followed for 12-months post-intervention to assess long-term intervention impact. </p><p><strong>Main Outcome Measures: </strong>Data on participant characteristics, physical activity, and intervention-related constructs were collected at baseline, 10 months, and 22 months. <strong></strong></p><p><strong>Results: </strong>Intervention session attendance was greater for FI compared with SEC participants (15.7 + 5.7 vs 12.4 + 7.3 sessions, respectively, P&lt;.01). After 10 months, FI and SEC participants significantly increased daily walking (+1,451 and +1,107 steps/ day, respectively) compared with SG participants (-128 steps/day). Increases were maintained after 22 months in the FI group compared with the SG group (+1092 vs. +336 daily steps, P&lt;.01). Between-group changes in accelerometer-assessed physical activity were not statistically significant at any time point. <strong></strong></p><p><strong>Conclusions: </strong>The FI intervention is a feasible strategy for short- and long-term increases in physical activity among African American women. Additional dissemination and evaluation of the strategy could be useful for reducing chronic disease in this high-risk population. <em></em></p><p><em>Ethn Dis.</em>2017;27(4):411- 420; doi:10.18865/ed.27.4.411. </p>

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
