Table 3. Proposed monitoring and evaluation indicators for Taiwan’s sodium reduction strategy.
| Domain | Indicator | Data source/frequency |
| Population intake | Mean 24-h urinary Na (g/day)61 | National Urinary Na Survey (2-year cycle) |
| Mean Na/K ratio | Same as above | |
| Food environment | Products meeting sodium benchmark (%) | Annual market survey |
| Front-of-pack “high-sodium” labeling coverage (%) | Label audit (annual) | |
| Average Na content in public institutional meals (including schools, hospitals, and workplaces) (mg/meal) | School procurement records | |
| Low-sodium salt (LSSS) | Public household use of LSSS (%) | Knowledge, attitudes, and practices (KAP) survey (3-year cycle) |
| Public institution kitchen adoption rate (%) | Procurement monitoring (annual) | |
| Healthcare system | Hypertensive patients receiving sodium coun-seling (%) | Hospital quality assurance (QA) audit (annual) |
| Patients referred to a dietitian (%) | Electronic medical record (EMR) review (annual) | |
| Outcome indicators | Hypertension prevalence (%)3 | National Health Survey |
| Mean SBP reduction (mmHg vs. baseline year) | ||
| CVD mortality attributable to high Na (%)61 | Vital stats/modeling (3-year cycle) |
Each key performance indicator (KPI) will include a data quality criterion (sample size, representativeness, and verification protocol) to ensure the statistical robustness and transparency of reporting.
