Utilizing geographic information system technology to address social justice

Lead poisoning, the silent killer with signs and symptoms mimicking other diseases, continues to play a major role in contributing to the public health burden of diseases. Although one of the most preventable environmental diseases, children remain the most vulnerable population for lead exposure. Despite substantial reduction in lead exposure in the United States, there are still approximately one million children with high levels of lead. Of the many risk factors for exposure, old homes with lead-based paint and lead in pipes are one of the major sources. Furthermore, social determinants of lead exposure such as geographical location in underserved areas with dilapidated housing may pose additional risks. The pervasive reality of lead exposure in underserved communities may lead to racism and classism, such as assumptions about intelligence and lifestyle. Although Mississippi recently implemented a lead poisoning prevention plan, its risk to environmental lead exposure remains unknown. Geographic Information System (GIS) Technology may offer insight into social determinants of lead exposure. Therefore, the Jackson State University Center of Excellence in Minority Health in Jackson, Mississippi, is utilizing this technology to examine correlates of social determinants and lead exposure. This is the first study in Mississippi to utilize GIS targeted screening to assess social justice issues. It has great public health significance in identifying determinants of environmental lead exposure in old homes; assisting public health officials in developing effective targeted screening programs to improve children's health, and implementing and enforcing health and social resources to prevent childhood lead poisoning.
