Abstract
Background: Hypertension (HTN) is prevalent in South Asian Canadians (SAC), and dietary sodium is the primary contributing factor. The overall goal of the South Asian Low-sodium sTudy (SALT) is to describe contextual factors and determine the feasibility of implementing a six-week low sodium community-based dietary intervention to improve outcomes in SAC with stage one HTN. Methods: SALT is a multi-method study consisting of a pilot randomized controlled trial (RCT) and a cross-sectional survey. Following ethics approval, participants with stage one HTN were randomized to a usual care group or an intervention group. Participants in the usual care group received the HTN Canada booklet and those in the intervention group received the SALT Intervention (culturally specific manual, five online modules, five weekly telephone calls). The Sodium Calculator, health literacy assessment short-form, Asian Indian Dietary Acculturation Measure (AIDAM), Knowledge, Attitude, and Behaviour (KAB) survey were utilized. A non-probability sample of SAC over 18 years was recruited for the survey. Results: A total of 292 SAC participated in blood pressure (BP) screenings, 35 (12%) were eligible for the pilot RCT. Of these, 23 (65.7%) consented. Results demonstrated some feasibility in terms of recruitment, retention, acceptability and one of the four components of intervention engagement. Participants lacked sodium-related knowledge and had positive changes in their attitudes toward lowering dietary sodium. Linear Mix Models found a significant effect of time but no effect for the group or group-by-time interaction in BP and a significant effect of group (p=0.044) and no effect of time (p=0.861) and group-by-time interaction for urinary sodium (p=0.0263). A total of 354 SAC completed the cross-sectional survey. Survey results suggest that SAC has a mean sodium intake of 2,117±1896 mg/day, and most of the respondents were concerned about their sodium intake but lacked sodium-related knowledge. Conclusion: The finding of the SALT study suggests that SAC consume a higher than Adequate Intake recommendation of sodium; they are concerned about their sodium intake but lack the knowledge for behaviour change. Results of the pilot RCT suggest that a six-week low sodium community-based dietary intervention is feasible and a larger RCT is warranted.

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.
