Resolve to Save Lives (Resolve) is a $225M implementation program led by Vital Strategies that will use proven interventions (initially sodium reduction, trans-fat elimination and antihypertensive therapy) to improve health in low- and middle-income countries. A primary goal for Resolve is to protect 1 billion people from excess sodium intake within 5 years. Our research will support this effort by providing quality, objective and independent evaluation of the sodium reduction program in China, where Resolve will commence activities.
Our primary objective will be to define effects on mean population sodium intake by making repeat population surveys of urinary markers. Secondary objectives will be to identify which components of the multifaceted Resolve intervention program are most effective, where and why. Our evaluation will use mixed methods research and will have three integrated components: 1. Stakeholder surveys – that provide a comprehensive understanding of the extent to which the Resolve program addresses the main issues, reaches the relevant parties and brings about the system changes required; 2. Population surveys – that directly measure the effects of the program among communities resident in high- middle- and low-resource settings in urban and rural areas across nine Chinese provinces. 3. Food retail surveys – that describe the nature of foods and ingredients available for purchase by the community, with a specific focus on measuring the sodium content of commonly consumed processed and restaurant foods.
For all objectives, evaluations will be done by making comparisons between baseline and follow-up levels of indicators, and assessing the differences between provinces that have, and have not, implemented the Resolve program. The data will be used to support an iterative process that engages the Resolve implementation team in a cycle of data collection, review, program update, and implementation enhancement, over a 5-year period.
