Design outcomes
Primary
| Measure | Time frame |
|---|---|
| 1. Dietary quality measured using 24-hr dietary recall at Baseline + follow-up measurements: Week 7 (post-treatment), Month 6, Month 9, and Month 12 2. Dietary diversity measured using dietary diversity tool at Baseline and weekly between Weeks 1-9 | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. BMI calculated using weight and height measurements, which are measured as follows. Height will be measured in a standing position, barefoot, using a Shorr Board portable stadiometer, recorded to the nearest 0.1 cm. Weight will be measured using a digital scale, recorded to the nearest 0.1 kg; participants will wear light clothing and no shoes. Measured at baseline, Week 7 (post-treatment), Month 6, Month 9, and Month 12. 2. Waist circumference measured using an inelastic tape measure, recorded to the nearest 0.1 cm. Measured at baseline, Week 7 (post-treatment), Month 6, Month 9, and Month 12. 3. Urinary biomarkers. Global metabolite profiling, sodium, potassium and nitrogen profiles will be obtained through the urine samples. The samples will be used for whole spectra analysis using NMR spectroscopy. Measured at baseline, Week 7 (post-treatment), Month 6, Month 9, and Month 12. 4. Nutritional literacy measured using the Healthy Diet Knowledge Assessment questionnaire at baseline, Week 7 (post-treatment), Month 6, Month 9, and Month 12. | — |
