Ambient UVR and Environmental Arsenic Exposure in Relation to Cutaneous Melanoma in Iowa
Intermittent sun exposure is the major environmental risk factor for cutaneous melanoma (CM). Cumulative sun exposure and other environmental agents, such as environmental arsenic exposure, have not shown consistent associations. Ambient ultraviolet radiation (UVR) was used to measure individual total sun exposure as this is thought to be less prone to misclassification and recall bias. Data were analyzed from 1096 CM cases and 1033 controls in t…
Impact of Rurality on Stage IV Ovarian Cancer at Diagnosis
PURPOSE: We aim to understand if rurality impacts patients' odds of presenting with stage IV ovarian cancer at diagnosis independent of distance to primary care provider and the socioeconomic status of a patient's residential census tract. METHODS: A cohort of 1,000 women with ovarian cancer in Iowa, Kansas, and Missouri were sampled and analyzed from the cancer registries' statewide population data. The sample contained those with a histological…
Temporal Trends in Satellite-Derived Erythemal UVB and Implications for Ambient Sun Exposure Assessment
Ultraviolet radiation (UVR) has been associated with various health outcomes, including skin cancers, vitamin D insufficiency, and multiple sclerosis. Measurement of UVR has been difficult, traditionally relying on subject recall. We investigated trends in satellite-derived UVB from 1978 to 2014 within the continental United States (US) to inform UVR exposure assessment and determine the potential magnitude of misclassification bias created by ig…

AGRICOH is a recently formed consortium of agricultural cohort studies involving 22 cohorts from nine countries in five continents: South Africa (1), Canada (3), Costa Rica (2), USA (6), Republic of Korea (1), New Zealand (2), Denmark (1), France (3) and Norway (3). The aim of AGRICOH, initiated by the US National Cancer Institute (NCI) and coordinated by the International Agency for Research on Cancer (IARC), is to promote and sustain collaborat…
Risk Factors for Animal‐related Injury Among lowa Large‐livestock Farmers
Context: Although farmers are at risk for injuries from contact with large livestock, few previous studies have examined risk factors for animal‐related injuries. Purpose: This case‐control study, nested in the Agricultural Health Study, aimed to assess risk factors for animal‐related injury among lowa large‐livestock farmers. Methods: A screener questionnaire sent to 6999 farmers identified 116 farmers with large livestock who had an animal‐rela…
Racial Differences in Factors that Influence the Willingness to Participate in Medical Research Studies
Use of Medicare Hospital and Physician Data to Assess Breast Cancer Incidence
OBJECTIVES: Health claims data have the potential of being an inexpensive, timely, and nationally representative source of information about cancer. This study examined the utility of Medicare hospital and physician data as an independent source to identify incident breast cancer cases. METHODS: Data came from Medicare and the National Cancer Institute's SEER cancer registries. From 1992, for women residing in the SEER states (n = 659,260), Medic…
Linked Insurance-Tumor Registry Database for Health Services Research
OBJECTIVE: Breast cancer screening and treatment data are often limited to restricted populations, including women older than 65 years old. The goal of this project was to develop procedures to link tumor registry and insurance claims databases on women younger than 65 years old with breast cancer and to assess the accuracy and validity of the linked dataset. METHODS: Iowa Cancer Registry (ICR) and Wellmark Blue Cross/Blue Shield of Iowa (BC/BS) …
Why are African Americans under‐represented in medical research studies? Impediments to participation
OBJECTIVES: In accordance with the NIH Revitalization Act of 1993, the National Institutes of Health and the Alcohol, Drug and Mental Health Administration require grant applicants and cooperative agreement participants to include minorities in human subject research. In an environment characterized by diminishing research dollars, this mandate has increased the pressure on investigators to determine factors that impede minority participation and…
The driver's license list as a population-based sampling frame in Iowa
Driver's license lists are infrequently used for population-based sampling, presumably because of suspicions of poor population coverage. The 1990 Iowa driver's license list was compared with the 1990 census to evaluate coverage by 5-year age group, sex, resident county, and urbanicity. Coverage exceeded 90% among 15- to 74-year-old men and 15- to 64-year-old women, with uniform coverage by county and county urbanicity group in these age ranges. …
The choice of weapons in firearm suicides in Iowa
This study reports the types of firearms used in firearm suicides in Iowa and tests the hypothesis that the use of handguns, rifles, and shotguns in such suicides reflects the availability of these weapons. The percentage of firearm suicides involving handguns increased from 36.6% in 1980 through 1984 to 43.3% during 1990 and 1991. In both time periods, the use of handguns was more likely than would be expected from their household prevalence. Ou…
Leukemia incidence and radioactivity in drinking water in 59 Iowa towns
Fifty-nine towns in Iowa with single source drinking water supplies were stratified on the basis of radium content in finished non-softened water to test the hypothesis of an association with total or acute myeloid leukemia. Fourteen towns had radium concentrations in drinking water exceeding the EPA safety limit of 5 picocuries per liter (pCi/L). A small increasing trend existed for total leukemia with increased radium content in drinking water …
