This surveillance project will assess NYC population sodium intake using the gold standard measurement of 24-hour urine collection. This surveillance project is a critical component of a larger initiative, coordinated by NYC, to reduce sodium intake nationwide through voluntary industry reductions in processed food sodium content. The project will assess current population sodium intake, against which population intake changes at three years can be assessed
