Introduction: Obesity and related diseases in persons over fifty years are of growing concern to policy makers in the District of Columbia. An assessment of obesity and various risk factors is an important step in designing model programs to improve the health and well being of residents. Objectives: This study was designed to correlate racial disparities in obesity with socioeconomic status in District residents, aged 50 years and older, and use Geographic Information Systems (GIS) to map their distribution. Methods: The data for this study were obtained from the Behavioral Risk Factor Surveillance System (BRFSS) database. The prevalence of obesity was determined using the Body Mass Index (BMI). Statistical analyses were conducted using the SUDAAN and SAS statistical software packages. The distribution of risk factors was mapped using Arcview 3.2 GIS software. Results: The highest prevalence of obesity was found in the poorest parts of the District but concentrated in certain zip codes. Low obesity prevalence was found in specific zip codes even in wards with the highest risks. The risk of obesity at age group 55-64 years was more than double that for age group 25-34 years. Although the lowest rate of obesity was found in the over $50,000 income group, the percentage of Blacks who are obese in this income group was more than twice that of whites. Conclusion: Policy-makers and program planners must be educated so that interventions could be focused in those parts of the District that are in greatest need.
