Campylobacter, a leading cause of bacterial gastroenteritis, affects 2.4 million people in the United States annually. Commonly reported individual risk factors include consumption of undercooked poultry and contact with contaminated water, pets, and livestock. Sociodemographic factors, including age and gender, have also been shown to influence the risk of campylobacteriosis. However, to our knowledge, no U.S. study has examined community-level (zip-code level) risk factors to evaluate potential socioeconomic and environmental disparities in the risk of Campylobacter infections. We linked Maryland FoodNet data (Campylobacter infection rates) to U.S. Census data (socioeconomic variables) and U.S. Census of Agriculture data (animal operation variables) at the zip-code level to evaluate the influence of community-level risk factors on the incidence of campylobacteriosis. Descriptive, inferential, and spatial statistics were completed using SAS, STATA, and ArcView GIS. African-Americans were less likely to contract Campylobacter infections than whites (IRR 0.74, 95% C.I. 0.72-0.76). Individuals living in 100% rural zip codes were twice as likely to contract Campylobacter infections as those living in 0% rural zip codes (IRR 2.00, 95% C.I. 1.87-2.13). People living in zip-codes characterized by a greater percentage of people >25 without high-school diplomas were less likely to contract Campylobacter (IRR 0.58, 95% C.I. 0.56-0.60). Finally, individuals living in zip-codes where broiler chicken operations and aquaculture operations were present were nearly 30% more likely to contract Campylobacter infections (IRR 1.26, 95% C.I. 1.24-1.28; IRR 1.3, 95% C.I. 1.24-1.27, respectively). These data show that community-level socioeconomic and environmental factors may play a role in the risk of campylobacteriosis in Maryland.
