Lay summary
In children, diets high in sodium (most commonly found in food as salt) and low in potassium (most commonly found in fresh fruits and vegetables) increase blood pressure and the risk of CVD later in life. This is especially concerning for Pacific children living in highly deprived areas, who face a disproportionate burden of nutrition-related health issues. This study aims to co-design, implement, and evaluate a culturally appropriate, community-based dietary intervention to reduce sodium intake and increase potassium intake among Pacific children aged 5-11 years in South Auckland. The intervention will be developed in partnership with Pacific parents, community leaders, service providers, and schools, and delivered in a real-world community setting. Sodium and potassium intake will be measured before and after the intervention using spot urine collection, interview-assisted 24-hour dietary recalls, and a checklist capturing discretionary salt use and food intake frequency.
