Factors affecting environmental awareness among Head Start families in Mississippi

Socioeconomic and racial/ethnic disparities in health status in the United States may be attributed in part to environmental injustice and differential exposure to environmental hazards among low-income and/or minority populations. However, the environmental justice movement has historically focused on equity in the siting of point-source polluting facilities, giving little attention to environmental hazards and environmental awareness at the level of the individual household.

Heads of 763 low-income households participating in Head Start programs in 20 counties of the Mississippi Delta region were surveyed regarding their education, the physical environment of their home and workplace, sources of food and water, awareness of local polluting sites/facilities, knowledge of government agencies, and behaviors that may affect their health or impact their local environment. Survey results were compared to demographic, socioeconomic, and environmental quality indicators.

Significant associations existed between both education and race/ethnicity and the responses of survey participants. Being African American was more commonly associated with poor quality-of-life indicators such as renting substandard older homes and living in close proximity to areas of unfavorable watershed quality. Higher education was more commonly and positively associated with indicators of heightened environmental awareness and increased political empowerment. No association was observed between race/ethnicity and the prevalence of polluting facilities. However, a significant association existed between race/ethnicity and indicators of environmental quality/integrity.

Environmental health education interventions that target individual households may be a useful mechanism for increasing the access of low-income communities to government health resources and reducing adverse health effects from the environment. However, racial/ethnic disparities in education and health remain an important consideration.
