Abstract
Context
This report shares the results of a novel environmental health needs assessment designed by the Environmental Health Sciences Research Center in collaboration with our community partners for the four-state region of Iowa (IA), Nebraska (NE), Missouri (MO), and Kansas (KS).
Objective
The goal of the needs assessment was to understand considerations about health and the environment among people living in the central Midwest states of Iowa, Nebraska, Kansas and Missouri, including their concerns, what they see as solutions, and what and how populations are vulnerable. These findings will inform future community engagement by the Environmental Health Sciences Research Center at the University of Iowa to improve environmental health.
Design
The assessment used a mixed-methods approach which included an online survey that collected quantitative and qualitative data and three focus groups with young adults, older rural adults, and immigrant and communities of color in eastern Iowa.
Setting
University of Iowa Environmental Health Sciences Research Center in collaboration with our community partners for the four-state region of Iowa, Nebraska, Kansas, and Missouri and focus groups in eastern Iowa.
Participants
Over 400 participants from four states.
Main outcome measure(s)
Describing residents’ perceptions of the connections between environment and health in the 4-state area and identifying notable differences between rural, urban, and suburban populations.
Result
Top issues of concern were water quality, outdoor air quality, climate change, chemical contaminants, and natural disasters. Respondents identified better policies, access to medical services, and financial resources as key components of reducing personal risk to environmental health issues. The focus group sessions highlighted concerns about housing, social capital, and the need for trusted sources of information.
Conclusions
These data suggest a holistic approach to environmental health topics, interest in policy interventions in rural communities, and potential for engagement with clinicians.

Introduction
Globally and in the United States, communities across the rural-urban continuum are grappling with extreme weather events and health disparities that stem from environmental contaminants. In the US central Midwestern states of Iowa, Nebraska, Kansas, and Missouri (designated by federal governmental agencies as Region 7) frequently experience extreme weather events exacerbated by climate change [1, 2] as well as environmental health exposures that stem from agricultural activities [3], housing deficiencies [4], and naturally occurring contaminants such as radon and arsenic [5, 6]. The Environmental Health Sciences Research Center (EHSRC) based at the University of Iowa is funded by the National Institute for Environmental Health Sciences (NIEHS) to address environmental health concerns in Region 7. The Community Engagement Core (CEC) of the EHSRC conducted a region-wide needs assessment to better understand residents’ concerns. The findings will be used to tailor community engagement activities to align with resident perspectives on environmental health issues and support the solutions they identify.
Background
The Environmental Health Science Research Center (EHSRC) at the University of Iowa, builds capacity in environmental health research. The goal of the EHSRC Community Engagement Core (CEC) is to address rural health disparities and enhance the community engagement of EHSRC research through meaningful collaboration with rural audiences. Community engaged research provides the necessary local context to understand environmental health issues. In a 2006 study, Larsson et al. explored how rural community leaders frame, interpret, and give meaning to environmental health issues affecting their constituents and communities [7]. Guiding their inquiry was the principle of upstream thinking, which considers the social, economic, and environmental origins of health issues that manifest at the population level [8]. To organize their inquiry, Larsson et al. created an interview guide based on Dixon and Dixon’s [9] integrative environmental health framework, which posits that environmental health information can be conceptualized into four domains:
Physiological (environmental agents and respective toxicodynamics – what are the problems? ).
Vulnerability (attributes that lead to increased susceptibility to environmental health risks – Who is affected by the problem? ).
Epistemological (how environmental risk information comes to be known and understood – How do people know about this problem? ).
Health protection (actions to reduce risks – What is done or should be done about the problem? ).
Our study adapts this framework to contextualize environmental health issues in EPA Region 7.
Perspectives on environmental health issues and appropriate solutions extend across ruralities and partisan lines. In a 2020 study of rural attitudes on climate change in the upper Midwest, Bonnie and colleagues concluded that perceptions of weather change and vulnerability to climate impacts depends on partisanship, with rural Republicans reporting experiencing less extreme weather changes than rural Democrats. They also found that rural voters were less supportive of government oversight of the environment than their urban/suburban counterparts. Attitudes toward government oversight were also correlated with views on climate change among both urban and rural voters [10]. This work informed the analysis of our findings by rurality and interest in policy solutions.
Methods
This mixed-methods needs assessment included a survey with both quantitative and qualitative responses followed by three focus group sessions. All study procedures were reviewed by the University of Iowa Institutional Review Board (IRB-01, #202308027), which determined that the project did not meet the regulatory definition of human subjects research because the activity is a needs assessment focused on a specific midwestern area and not intended to be generalizable.
Survey development
Our survey was developed to help the CEC respond to the environmental health concerns expressed by residents in our four-state region of Iowa, Nebraska, Missouri, and Kansas. Survey development began with a guided discussion with the Stakeholder Advisory Board (SAB) of the EHSRC. This group meets bi-annually and includes representation from county public health offices, environmental advocacy groups, citizen activists, medical providers, and other public health professionals. The SAB helped generate topic areas for survey respondents to prioritize, audiences for distribution, and questions for qualitative data collection. In addition, we consulted affiliated scientists in the EHSRC which includes environmental advocates, county environmental health specialists, physicians, toxicologists, and environmental health researchers. Finally, available literature informed the survey development. For example, in Robson & Schneider’s [11] study of rural health care providers’ beliefs about environmental health issues challenging their communities, emergent issues included water pollution, pesticide misuse, and soil erosion. We conducted a literature review through PubMed using search terms including “environmental health issues,” “environmental health needs assessment,” “environmental needs assessment,” and “citizen science environmental health.” From the search results, we selected ten articles that included frameworks on community-based participatory research in environmental contexts, particularly in rural or Midwest settings. We developed the questions on the survey instrument based on a synthesis of these sources and organized them based on the four domains described above developed by Larsson, et al. [7].
We pilot tested the survey among our own personal networks to ensure clarity in the questions and to invite feedback from these first participants about question clarity, flow, and survey length (N = 49). We did not make any substantial changes to the survey following the pilot. We also collected responses through SAB networks and EHSRC member networks (N = 93). The audience for this distribution was different, primarily academics and advocates in environmental health, as opposed to a representative sample of community members. As a result, this dataset was analyzed for program purposes only and is not included in the analysis here.
Survey structure
The survey included a mix of Likert scale questions (all were a 1–5 scale with 5 indicating the “most” or “worst”), multiple choice, and open-ended questions. In cases where respondents were asked to rate their level of concern about or select from of a list of items, the items were presented in random order to each respondent. Participants also provided demographic information, including whether they consider themselves to live in a rural, suburban, or urban environment. All questions were “forced,” requiring respondents to answer. The full survey instrument is included as supplementary material.
Each domain of interest was introduced to respondents as follows:
The first domain, physiological, was introduced to survey respondents with the following statement: In this section, we will be asking about what you see as important environmental problems that can affect human health. Respondents were asked to rate how much they thought the environment influenced people’s health, indicate their level of concern about several environmental health issues, and select environmental health issues of concern in their home.
The vulnerability domain of the survey was introduced with the following statement: In this section, we will ask about who you think is affected by environmental health issues. This section asked participants to reflect on how vulnerable they perceived themselves, as well as others in their communities.
The epistemological domain was introduced with the statement: In this section, we will be asking about what and how you know about environmental health issues.
The fourth domain, health protection, was introduced to survey respondents with the following statement: In this section, we will be asking about what you think is being done or should be done about environmental health issues. Respondents were asked to indicate how able individuals in their communities were to protect themselves, if they felt they would have help in the event of a natural disaster, individuals or organizations that are responsible for protecting residents, and services or resources that would be most beneficial to reduce personal risk.
Survey distribution
The Iowa Social Science Research Center (ISRC) managed survey distribution. The ISRC contracted with a web panel vendor, Qualtrics Research Services (QRS), to field the survey electronically to a demographically representative sample of 400 respondents, with 100 respondents from each of the four states. Adults 18 years and older residing in these states were recruited to participate. To obtain a census-representative sample per region, quotas were set on the following demographics: age, gender, ethnicity, and race. QRS managed quotas throughout data collection to achieve the desired number of completed survey responses. A full methodology report is included in the supplementary material.
Focus groups
Three focus groups were conducted to collect narrative, in-depth qualitative data. Each focus group aimed to better understand the perspectives of a particular demographic: young adults, older rural adults, and immigrants or people of color. All focus group participants were recruited locally within the University of Iowa College of Public Health student population and through existing community partner lists maintained by the EHSRC CEC. Young adults comprise an important demographic to focus on future solutions, and both older rural adults and immigrant and POC populations may have higher vulnerabilities to environmental health exposures. Focus group discussion guides were semi-structured to allow for participants to describe their own experiences. The guides were developed in relation to the survey questions and organized by the four domains outlined in Larsson, et al. (2006), as described above. Participants were invited to brainstorm environmental health issues that affect them, reflect on community members who are most vulnerable to environmental health issues, and describe entities able to solve environmental problems. Each focus group was led by two study authors, one who led the discussion and the other who took detailed notes and ensured the sessions stayed within a 90-minute timeframe. The focus groups were audio recorded using the Voice Memos application and transcribed using Amazon Business Suite. All focus group participants were compensated with $10 Amazon Gift cards for their time. They were informed about compensation when they consented to participate.
Statistical analysis
The quantitative approach was primarily descriptive. Mean and medians were calculated to summarize responses to survey questions. Chi-square tests were used to detect differences in survey responses across racial groups and ruralities. A p-value < 0.05 was taken as significant. All analyses were conducted in R via RStudio version 4.4.2.

Analysis of qualitative responses identified eight related themes: political apathy, concern for the future, call for collective action, positive environmental action, issues are overstated, negative health impacts, related to agricultural/rural exposures, and social determinants of health. Table 3 presents the themes, number of responses, and exemplar quotations.
Table 3.
Additional comments about environmental health issue concerns
| Theme | N | Example quotation |
|---|---|---|
| Political Apathy | 16 | “My concern, and the reason I’m pessimistic about alleviating climate change issues, is that many politicians and governments don’t take the matter seriously. For example, a presidential candidate who won your state’s caucus has said that if he wins he’ll drill, drill, drill.” |
| Concern for the future | 15 | “I worry about future generations. How will they manage if we do not do something now each and every day. We need to conserve our energy and resources for future generations. We must be careful and not waste what we have.” |
| Call for collective action | 25 | “We need to take care of our environment as much as we can. Natural events contribute to environmental contamination, so we need to mitigate their effect as much as possible by reducing our contribution to the problem.” |
| Positive Environmental Action | 4 | “I think the EPA has prevented much of what we were exposed to a couple of generations ago (or more), but there’s still work to be done. The emissions from vehicles still need to eventually stop or be drastically reduced.” |
| Issues are overstated | 4 | “I feel many people are blowing environment issues too much out of proportion - God is still in control of His creation” |
| Negative health impacts | 13 | “Our air quality seems to be getting worse with every passing year. I have really bad allergies year round. Now it has turned into allergic asthma” |
| Related to agricultural/rural exposures | 5 | “The air, soil, and water are all important in Iowa because we are an agricultural state. My Grandfather used to farm. He is retired now but still leases out his land to be farmed.” |
| Social determinants of health | 3 | “So I stay in Salina, KS and because of my financial struggles at the moment I am experiencing neighbors who pollute indoors the building and it affects my health in a bad way.” |
Focus group respondents added further nuance and complexity to these findings. In particular, they showed how the areas of concern are not discrete topics; rather, people consider cumulative and additive effects of multiple hazards. For example, one rural resident stated: “I would say in addition to water quality, air quality by pesticide uses, you know, sprays. We lived out in the country. I was mowing the lawn one day, had ear buds on, so I couldn’t hear what was going on around me, but a farmer was spraying, and I didn’t know it until I could taste it in my mouth. And the wind was blowing directly at me. So air quality also.” In this case, while the participant initially implicated pesticides as a water quality issue, they also considered how they affect air quality.
Respondents were also asked to reflect on their home environment. Overall, the top three environmental health issues of concern in the home were Drinking Water Quality, Mold, and Pests Inside My Home. When analyzed by rurality, Drinking Water Quality and Mold were the most and second most common concern among all ruralities. Suburban and urban respondents reported Pests Inside the Home as the third concern, while rural respondents reported Agricultural Dust or Drift (Fig. 1).
Fig. 1.
Percentage of health concerns by rurality
Participants in the focus group with mostly immigrants and people of color discussed the issue of pests in the home at length, describing several pest concerns, especially cockroaches and bedbugs. In addition, they described health impacts and identified responsible parties for these pests. For example, one responded noted, “It’s just like a massive infestation of cockroaches and other insects that was harmful for my kids because one of the kids had asthma and, uh, at the same time, the property management had enough power for me that I was kind of locked in the system… the point in here is many of the families do not have this power. So, they really get stuck even if this is detrimental to the health of the kids.”
Vulnerability domain
Most respondents viewed themselves as the same level of vulnerability as others (70.4%) followed by 17.3% as more vulnerable and only 12.3% as less.
Children and senior citizens were identified as the most vulnerable to environmental health issues. When invited to comment, respondents noted that the children are especially vulnerable due to their immune systems and increased exposures to floors and lead dust. Senior citizens also carried the concerns of immune systems plus co-morbidities associated with age. Respondents also described social determinants of health as being related to environmental health issues; examples included homelessness and weather, income, access to medical care, veteran status, and discrimination. One individual also noted that “we are all vulnerable” to extreme weather and other climate events.
When analyzed by racial identity, the respondents from minoritized backgrounds were statistically more likely to identify racial or ethnic minorities as a vulnerable population than white respondents (white: 19.9% and minoritized: 32.7%, χ2 = 6.7, p < 0.01). This same trend holds true for selecting immigrant populations as a vulnerable population (white: 20.3% and minoritized: 29.1% non-white, χ2 = 6.7, p = 0.01).
To understand how respondents conceptualized community-level vulnerabilities, we asked them to identify assets their communities had to prepare for a natural disaster. Respondents listed various physical infrastructure such as community buildings, resources and materials like sandbags and flood pumps, and communication systems. Respondents also identified leaders and public servants, organizations, and average citizens who work together to take care of each other. Table4 presents how perceived community and household preparedness varies by rurality.

# IQR = Interquartile Range
## SD = Standard Deviation
Overall, respondents view both their community (mean 3.0) and individual household (mean 3.0) as moderately prepared for a natural disaster. Among ruralities, there were non-significant but observable differences. Perceived community-level preparedness was lowest among rural participants (mean 2.8) and highest among suburban (mean 3.2); urban respondents fell in the middle (mean 3.0). For household preparedness, both rural and suburban respondents averaged 3.1. Thus, rural respondents may perceive their households to be more prepared than their communities, but suburbanites view their communities as more prepared than their individual households. Urban respondents rated their community preparedness (mean 2.9) as the same as their household preparedness (mean 2.9).
Epistemological domain
Overall, respondents considered themselves moderately knowledgeable about environmental health issues. Over half (62.9%) said that environmental health issues do not get enough attention, 30.5% said they receive the right amount of attention, and only 8.3% responded that environmental issues receive too much attention.
When seeking environmental health information, respondents consult their local health department, local media, state agencies, and federal agencies. The most common social media news source of environmental health information was Facebook, followed by YouTube and TikTok. These responses were consistent across rurality (urban, rural, and suburban).
In this domain, participants were also asked about their level of optimism and pessimism about the environment. Those who reported higher knowledge about environmental health issues also reported higher levels of optimism about the environment, while low levels of environmental health knowledge were correlated with higher levels with pessimism (χ2 = 64.1, p < 0.01). However, in a somewhat contradictory finding, people with higher self-reported knowledge reported higher levels of concern across several environmental health issues (Domain 1). This was most prevalent with climate change, indoor air quality, natural disasters, chemical contaminants, heavy metal exposure, and conservation.
Health protection domain
When asked, “Do you feel you would have access to help if you experienced problems related to the environment (housing issue, natural disaster, flooding, extreme weather)?” most respondents (51.9% N = 213) responded “yes;” 22.4% (N = 92) responded “no,” and 27.1% (N = 111) responded “I don’t know.” When comparing respondents who indicated “yes” or “no,” suburban residents were the most likely to respond “yes” (82%) and urban residents had the highest proportion of indicating “no” (39%).
The next question asked, “What individuals or groups are responsible for protecting residents from environmental health problems in our region?” Responses were open ended and thematically coded into the following domains: local leadership, state agencies, federal agencies, non-profits, and other groups. Notably, 67 respondents (16%) noted “government.” Other specific responses included mayor, police, the Federal Emergency Management Agency (FEMA), Environmental Protection Agency (EPA), Red Cross, churches, food banks, lawyers, as well as “we each are,” and “we have a local emergency director who has many responsibilities including environment, health, natural disasters, etc.”
Respondents were asked, “which of the following would be the most beneficial to you in reducing your personal risk for environmental health issues?” They were restricted to selecting one of the following options, which were randomized so that they were not listed in the same order for each participant:
Financial resources to make improvements in in housing or other personal risk factors.
Better policies at the local, state, or federal level to reduce the risk of environmental health issues.
More information about environmental health issues.
Better access to medical services/health screenings that could identify health problems caused by environmental issues.
Environmental sampling/monitoring in my community to identify health risks.
Changes in my workplace or work environment.
Other (please describe).
Overall, respondents prioritized better policies first, followed by better access to medical screenings, and then financial resources to make improvements. Perceived ways to reduce personal risk significantly differed by rurality (χ2 = 22.5, p = 0.03). Urban respondents reported better access to medical services as most important and suburban and rural respondents reported better policies.
As seen in Fig. 2, urban communities reported access to medical services as the number one way while suburban and rural communities reported better policies.
Fig. 2.
Percentage of ways to reduce personal risk by rurality
Participants in the rural focus group elaborated on policy solutions, describing strategies that would hold polluters or emitters accountable, including direct action such as banning pesticide application on household lawns. Some participants expressed doubt that policy actions are feasible; one stated, “I don’t think that, at least the Iowa legislature, I don’t think they always respond to what the voters want.”
Discussion
We conducted a multi-state needs assessment to understand environmental health issues in the Midwest using four domains – physiological, vulnerability, epistemological and health protection – to create more effective environmental health outreach and communication strategies. Our focus group discussions demonstrate how communities experience environmental health issues holistically because poor housing, pollution, and water quality issues often occur alongside each other. This is consistent with other studies; for example, Crighton and colleagues [12] investigated how new mothers perceive environmental health risks to their children. Even though researchers identified a wide range of environmental risk perceptions among participants, they found that any health-promoting action taken by the mothers was grounded in their daily sensory experiences of those issues. Similarly, White and Hall [13] found that participants identified environmental hazards in their community based on their direct experiences with the hazards. Together, these studies show that community members use their tangible, lived experiences to understand environmental health issues. This may contribute to why the discrete survey responses did not clearly differentiate levels of concern between different environmental health issues.
Our findings support intervention approaches that center community members’ lived experiences and local context to be effective [14]. Future interventions could employ an approach that reflects the reality of overlapping environmental health issues by organizing partners across several different sectors of the community (i.e., housing, transportation, emergency management, agriculture). This strategy supports comprehensive, community-centered interventions that may better resonate with communities and reduce environmental health disparities.
Our survey revealed a moderately contradictory relationship between knowledge and environmental optimism. High self-reported knowledge about environmental health issues was positively correlated with optimism about the environment, whereas low knowledge was associated with greater pessimism. Interestingly, participants with higher self-reported knowledge also reported elevated concern across several environmental health issues. One possible explanation is that increased knowledge may also include awareness of interventions or policies to mitigate environmental issues, fostering optimism about potential solutions. Conversely, low knowledge may leave individuals feeling helpless, fueling pessimism.
Colombo and colleagues [15] provide a useful framework for interpreting these findings. They distinguish between three types of environmental knowledge: action-related (knowing what can be done), system knowledge (theoretical understanding of environmental issues), and effectiveness knowledge (understanding the benefits of environmentally friendly behaviors). Only action-related and effectiveness knowledge directly influence behavior. In the context of our results, participants may have self-reported high system knowledge, which may explain the coexistence of optimism and concern: they recognize environmental problems, but may lack the deeper action-related or effectiveness knowledge that would translate concern into pessimism.
This finding suggests that outreach and education strategies can drive environmental optimism and constructive engagement by emphasizing action-related and effectiveness messaging. For example, educational programming could emphasize the link between pro-environmental behaviors and tangible outcomes, such as highlighting case studies of local environmental actions and their measurable impacts.
We also sought to understand which groups were perceived to be most at risk to better develop programming for these communities and population groups. Our finding that children and elderly age populations are viewed as vulnerable is consistent with the literature. Risher et al. [16] examined how elderly populations are particularly impacted by environmental exposures for biological and medical reasons. Others have explored how children are susceptible to environmental hazards in the first 1000 days of life through exposures primarily in the home [17]. The authors also acknowledge non-environmental factors such as socio-economic status and emerging environmental issues as particularly relevant to these populations. Our finding that rural residents perceive their household preparedness to be higher than community level preparedness suggests that more needs to be done to strengthen rural community preparedness. Rahe et al. [18] examined community ties in rural development projects and found that financial resources and social capital are intertwined and should both be used to boost prosperity. Conversely, given that urban and suburban respondents viewed communities as more prepared than individual households, outreach efforts in these areas could be focused on increasing individual and household preparedness and confidence.
Implications for policy and practice
One somewhat surprising finding was the interest in policy solutions from rural respondents. Rural communities have been seen as distrustful of regulatory governance [19], including in relation to environmental policy. Scholars have long characterized the rural distrust of environmental policy as a binary distinction in opposition to urban acceptance [20]. In addition, rural communities have high exposures to extractive industries as well as deep economic ties to these industries [21, 22]. As a result, rural residents observe or engage in environmentally detrimental practices and bear most of the associated physical, social, and material costs [23, 24]. Our finding that rural residents support policy intervention suggests an opportunity to identify acceptable and effective policy solutions for environmental health issues in rural areas. Further research focusing on factors that influence policy acceptability [25], perceived effects of policy [26], or overcoming structural barriers to policy change [27] may be fruitful next steps.
Urban residents showed interest in clinical solutions and increased access to medical services. Clinical solutions to environmental health issues are being explored. For example, physicians have shown to acknowledge the importance of discussing the health impacts of environmental exposures in workplaces and residences with patients [28]. Despite urban residents being interested in these interventions and physicians valuing the importance of discussing these topics with patients, many physicians do not frequently ask their patients about environmental exposures, and most physicians have not received recent trainings on environmental exposures. Many physicians have knowledge gaps about environmental exposures, including PFAS which is a common contaminant in drinking water, a category that urban residents indicated as a top health concern [28]. To support access and frequency of discussing environmental health topics with clinicians for urban residents, developing environmental exposure training and resources for clinicians and integrating relevant screenings at medical visits may be productive next steps.
Finally, better linkages between local environmental health professionals, who are responsible for identifying community-level environmental health risks, and clinicians through collaborative engagements, coursework, or workshops could help further bridge these gaps [29]. Environmental health professionals are often housed in public health departments overseen by county-level government. This means that they are not well connected to local health care systems and settings. As Cascio and Christian [29] point out, there are numerous opportunities to improve connections between these entities. For example, improving clinicians’ access to air quality data collected by EPA, and distributed via a local health department, can help clinicians better serve vulnerable populations (e.g., those with asthma or respiratory disorders). The authors suggest that “availability of resources prior to an emerging event can enable clinicians to quickly access environmental information they were previously not well versed in and provide health-protective information to their patients” [29].
Conclusion
The Community Engagement Core (CEC) of the Environmental Health Sciences Research Center (EHSRC) based at the University of Iowa conducted a region-wide needs assessment to better understand residents’ concerns, knowledge, and ideas for intervention. We will use these findings to tailor community engagement activities to align with community perspectives on environmental health issues and support the solutions they identify. For example, the finding that rural residents are interested in policy solutions suggests an opportunity to develop robust policy and advocacy education for rural residents. Respondents’ reliance on local health departments motivates us to develop stronger relationships with county-level public health offices to provide resources. Survey respondents from Iowa, Nebraska, Kansas, and Missouri identified numerous environmental health challenges, as well as assets and needs within their local communities. These data will inform future environmental health education, outreach, and interventions in EPA region 7.
