The Impact Of Travel Time On Colorectal Cancer Stage At Diagnosis In A Privately Insured Population, Mesnad Alyabsi, Mary Charlton, Jane L. Meza, K. M. Monirul Islam, Amr Soliman, Shinobu Watanabe-Galloway

Journal Articles: Epidemiology

BACKGROUND: Rural residents are less likely to receive screening for colorectal cancer (CRC) than urban residents. However, the mechanisms underlying this disparity, especially among people aged 50-64 years old with private health insurance, are not well understood. We examined the impact of travel time on stage at CRC diagnosis.

METHODS: This retrospective cohort study used data from the Blue Cross and Blue Shield of Nebraska. Members of this private insurance company aged 50-64 years, diagnosed with CRC during the period 2012-2016, and continuously enrolled in the insurance plan for at least 6 months prior to CRC diagnosis, were selected for …

Individual- And County-Level Determinants Of High Breast Cancer Incidence Rates, Mario Schootman, Kendra Ratnapradipa, Travis Loux, Allese Mcvay, L. Joseph Su, Erik Nelson, Susan Kadlubar

Journal Articles: Epidemiology

Background: Age-adjusted breast cancer rates vary across and within states. However, most statistical models inherently identify either individual- or area-level determinants to explain geographic disparities in breast cancer rates and ignore the effects of the other level of determinants. We present a micro-macro modelling approach that incorporates both levels of determinants to better explain this variability and to discover opportunities to reduce breast cancer rates.

Methods: Individual-level data about breast cancer risk factors from eligible Arkansas Rural Community Health (ARCH) study participants (n=13,554) was supplemented with publicly available county-level data using a novel micro-macro statistical approach. This model uses individual-level …

Consequences Of Pathogen Lists: Why Some Diseases May Continue To Plague Us, David Brett-Major, Trina Racine, Gary P. Kobinger

Journal Articles: Epidemiology

The current strategy used by many funding agencies for determining how money is spent on research to help prevent infectious disease outbreaks is based on pathogen-specific priority lists. Listing disease threats provides focus for business and research planning conducive to specific goals of developing a drug, or a vaccine, or other particular product. But, this singular type of focus has consequences. This perspective explores the consequences of lists, and describes how parallel programming independent of disease lists that address what we need to do to prevent and mitigate emerging disease risks may provide benefits out of reach of a singular …
