RESUMO
GeoHealth research both characterizes and predicts problems at the nexus of earth and human systems like climate change, pollution, and natural hazards. While GeoHealth excels in the area of integrated science, there is a need to improve coordinated and networked efforts to produce open science to enable environmental justice. There is a need to resource and empower frontline populations that are disproportionately marginalized by environmental injustice (i.e., the unequal protection from environmental harms and lack of access and meaningful engagement in decision making for a healthy environment; EPA, 2022, https://www.epa.gov/environmentaljustice). GeoHealth practice has the opportunity to advance environmental justice or the "fair treatment and meaningful involvement of all people regardless of race, color, national origin, or income" with respect to how research and collaboration of GeoHealth professionals supports the "development, implementation, and enforcement of environmental laws, regulations, and policies" that produce equal protection from environmental and health hazards and access to the decision making for a health environment (EPA, 2022, https://www.epa.gov/environmentaljustice). Here we highlight barriers and opportunities to apply an equity-centered ICON framework to the field of GeoHealth to advance environmental justice and health equity.
RESUMO
OBJECTIVES: Cancer of the oral cavity and pharynx remains one of the 10 leading causes of cancer deaths in US. Besides smoking and alcohol consumption, there are no well-established risk factors. While poor dental care had been implicated, it is unknown if lack of dental care, implying poor dental hygiene predisposes to oral cavity cancer. This study aimed to assess the relationship between dental care utilization during the past 12 months and the prevalence of oral cavity cancer. METHODS: A cross-sectional design of the National Health Interview Survey of Adult, noninstitutionalized US residents (n=30 475) was used to assess the association between dental care utilization and self-reported diagnosis of oral cavity cancer. Chi-square statistic was used to examine the crude association between the explanatory variable, dental care utilization and other covariates, while unconditional logistic regression was used to assess the relationship between oral cavity cancer and dental care utilization. RESULTS: There were statistically significant differences between those who utilized dental care during the past 12 months and those who did not with respect to education, income, age, marital status, and gender (P<0.05), but not health insurance coverage (P=0.53). In addition, those who utilized dental care relative to those who did not were 65% less likely to present with oral cavity cancer, prevalence odds ratio (POR), 0.35, 95% confidence interval (CI), 0.12-0.98. Further, higher income, advanced age, people of African heritage, and unmarried status were statistically significantly associated with oral cavity cancer (P<0.05), but health insurance coverage, alcohol use, and smoking were not, P>0.05. After simultaneously controlling for the relevant covariates, the association between dental care and oral cavity cancer did persist but imprecise. Thus, when compared with those who did not use dental care, those who did were 62% less likely to be diagnosed with oral cavity cancer, adjusted POR, 0.38, 95% CI, and 0.13-1.10. CONCLUSIONS: Among US adults residing in community settings, use of dental care during the past 12 months was marginally statistically significantly associated with oral cavity cancer, but clinically relevant in assessing oral cavity cancer prevalence in this sample. However, because of the nature of our data, which restricts temporal sequence, a large sample prospective study that may identify modifiable factors associated with oral cavity cancer development, namely poor dental care is needed.
