Radon Environmental Health Literacy among Health Council Participants in Northeast Tennessee

Radon, a radioactive gas, poses significant health risks, including lung cancer, and is prevalent in indoor environments. Understanding radon testing behavior and Environmental Health Literacy (EHL) is crucial for individuals to take appropriate preventive measures.

This study assessed radon-related EHL among Health Council participants in seven Northeast Tennessee (NETN) counties and examined associations between sociodemographic factors and EHL levels. Understanding radon knowledge and behaviors within this influential group is critical, as they often serve as trusted public health advocates.

A cross-sectional survey was conducted from September - November 2023 among Health Council participants across seven counties in NETN, assessing sociodemographic characteristics and radon EHL. Descriptive statistics and linear regression analyses were employed to examine associations between sociodemographic variables and radon EHL scores.

A total of 131 Health Council members participated in the study. Of these total participants, the majority of participants were homeowners (60.3%). While 80.2% of participants had heard of radon, only 12% had tested their homes for it. TV commercials were the primary source of radon information. Younger age (p<0.001), renters (p<0.001), and those of Hispanic ethnicity (p=0.033) were associated with decreased EHL scores.

Study's findings reveal disparities in radon knowledge, testing behavior, and EHL among Health Council participants in NETN. Tailored risk communication strategies considering demographic factors are essential to bridge the radon EHL gap. Collaborative efforts between public health agencies, policymakers, and community members are crucial to enhancing radon knowledge and testing uptake.
