      Background: Children in Flint, Michigan were exposed to lead at unsafe levels in drinking water bringing renewed interest and national attention to an old public health problem. In Georgia, thousands of children are exposed annually to lead at unsafe levels primarily from paint in homes built before 1978. With lead poisoning typically viewed as an urban problem, rural areas are often considered lower-risk in light of similar lead poisoning risk factors, albeit on a smaller scale. The purpose of this preliminary study was to examine the prevalence of elevated blood lead levels in children <6 years of age tested in rural Ben Hill County, Georgia, a county designated as lower risk. Methods: Lead surveillance data from the Georgia Department of Public Health (DPH) were analyzed using SAS®v-9.3 to calculate the prevalence of elevated blood lead levels (≥5ug/dL) among those children in Ben Hill County who had been tested for lead; the results were compared to state and national data. Results: A preliminary analysis of 2010-2015 screening data for Ben Hill County indicates that 8.73% (95%- CI: 7.4%-10.1%) of children who were tested for lead exceeded the Centers for Disease Control reference level (≥5ug/dL). This is approximately 3.5 and 2.4 times higher, respectively, when compared to national (2.5%) and state (3.64%) percentages of children exposed to lead ≥5ug/dL. Analysis also indicated low screening rates, which limits interpretation of population prevalence. Conclusions: Lead poisoning is often viewed as an urban, inner-city problem due to a higher percentage of older homes clustered together, exposing more children, compared to rural areas with homes geographically dispersed. While these data are preliminary and more analysis is planned to understand the problem, it highlights lead poisoning risks rural communities face that are often overlooked in population-based risk analysis and research on lead exposure in children.
    • Use of geographical information systems to identify counties in Georgia with high risk for childhood lead poisoning

      Background: For children in Georgia, lead poisoning is a substantial public health problem. Primary risk factors include low socioeconomic status and poor-quality housing built prior to 1978. The Environmental Health Team of the Georgia Department of Public Health (DPH) utilized geographical information system (GIS) technology and census housing data to identify counties in which children have high risk for lead poisoning. The purpose of this research was to update and refine previous maps developed with older technology and on a different geographic scale so that targeted public health interventions can be developed. Methods: Data related to stratified and median housing age data were derived from the 2013 5-year American Community Survey. With ESRI ArcMap 10.2 geographic information software, the data were geospatially linked to the state’s county shapefile for development of spatial maps. Results: A series of spatial maps were developed utilizing housing risk factors of age and occupancy status. Refined spatial maps were developed for: 1) the percentage of homes built prior to 1978 and prior to 1950 per county; 2) owner- and renter-occupied housing stratified by age and color-coded per county; and 3) counties in which children were at high risk for lead poisoning. Conclusions: The data from this research provides information for the DPH Lead and Healthy Homes program of areas in the state where targeted interventions are needed. The updated maps can be used to educate policy makers, healthcare providers, and community leaders in regard to prevention of lead poisoning.
