Intention to adopt a healthy diet among women with and without a history of gestational diabetes: Constructs and beliefs from the theory of planned behavior
Bibliographic record
Abstract
Women with a history of gestational diabetes (GDM) have difficulty maintaining a healthy diet after delivery. The theory of planned behavior (TPB) is effective in identifying the determinants of adopting a healthy diet. The objectives were to identify the determinants of the intention to adopt a healthy diet among the TPB constructs in women with (GDM+) and without (GDM-) a history of GDM, and to identify the beliefs associated with these constructs. The study was conducted in Québec (Canada) between 2009 and 2017. Data from 213 GDM+ and 91 GDM- women were analyzed. Women completed a questionnaire on the determinants of intention to adopt a healthy diet, defined as adherence to 2007 Canada's Food Guide. The subjective norm and perceived behavioral control (PBC) constructs were associated with the intention to adopt a healthy diet among GDM+ women (β = 2.21 and β = 4.37, respectively, p < 0.0001), whereas among GDM- women, PBC was the only construct associated with intention (β = 0.78; p < 0.0001). More specifically among GDM+ women, the disapproval of a family member other than the partner (β = 1.49; p = 0.0005), not feeling capable of adopting a healthy diet with access to food treats (β = 1.58; p < 0.0001), lack of free time (β = 1.31; p = 0.002), lack of information about healthy eating (β = 1.02; p = 0.015) or lack of easy recipes to prepare (β = 0.84; p = 0.042) was associated with a lower intention to adopt a healthy diet. Overall, among GDM+ women, different beliefs related to the subjective norm and PBC could be targeted to improve the eating habits of this specific population.

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.
