Public Health Approach to Addressing Hyperphosphatemia Among Dialysis Patients

Elevated serum phosphorus levels are a major source of morbidity and mortality for the 350,000 Americans receiving chronic dialysis treatment. Despite the widespread application of medical and behavioral interventions, the prevalence of hyperphosphatemia remains exceedingly high. At first glance, a public health perspective may seem inappropriate for addressing a disorder of mineral metabolism among patients receiving a life-sustaining treatment. However, we analyzed this topic from a public health perspective and identified many opportunities to improve the management of hyperphosphatemia, including (1) media and cultural messages about food, (2) the availability of appropriate foods and medications, (3) physical structures such as the location of products in grocery stores, and (4) social structures such as food-labeling laws.
