Reduction of Salt and Sugar Contents in Canteen Foods and Intakes By Students and Staff at a Malaysian Higher Education Institution: Protocol for a Mixed Methods Study
Bibliographic record
Abstract
BACKGROUND: University students and staff members, especially those who frequently eat out and spend considerable time on campus, form a crucial demographic facing challenges related to high salt and sugar intake in out-of-home food. Recognizing the high prevalence of eating out among these populations, it is imperative to understand the salt and sugar consumption levels of campus communities. OBJECTIVE: This protocol describes the rationale and design of a 3-part cross-sectional and longitudinal interventional study to reduce salt and sugar contents in canteen foods and intakes among students and staff at Sunway University and Sunway College in Malaysia. METHODS: First, the knowledge, attitudes, and practices (KAPs) and perception, barriers, and enablers (PBEs) of salt and sugar intake and reduction were assessed among students and staff (part 1 of the study). Second, the KAPs and PBEs of salt, oil, and sugar reduction were assessed among canteen staff (part 2 of the study). Third, a longitudinal interventional study was conducted by implementing a campus-wide executive order to reduce salt and sugar in all foods sold on campus (part 3 of the study). The salt and sugar contents of selected foods were measured at baseline and at 3 months and 6 months postreduction. Participants who eat frequently on campus were selected as the intervention group, while those who do not comprised the control group. All participants had their urine electrolytes and body compositions measured and recorded 24-hour dietary intakes for 2 weekdays and 1 weekend at baseline, 3 months, and 6 months after salt and sugar reduction. RESULTS: The study protocols were approved by the institutional review board of Sunway University (SUREC 2024/029 and SUREC 2024/040). Recruitment for the cross-sectional studies began in May 2024, while that for the longitudinal intervention study began in June 2024. The 6-month intervention began in September 2024 immediately after the official launch of the campus-wide executive order to reduce salt and sugar. We targeted recruitment of 1000, 50, and 300 participants for parts 1, 2, and 3, respectively. We anticipate reduced dietary salt and sugar intakes by 30% and 50%, respectively (World Health Organization targets), and beneficial health effects on the participants. CONCLUSIONS: The insights gained from this study will help to create a healthier food environment, benefitting individuals who regularly eat out, especially at the workplace.

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.
