Herd and environmental determinants of reproductive performance in Swedish dairy herds, 2001-2009
Publication date: Available online 31 July 2019Source: Spatial and Spatio-temporal EpidemiologyAuthor(s): M.A. Stevenson, E. Löf, M. Söderström, H. Gustafsson, U. EmanuelsonAbstractThis was a retrospective cohort study of Swedish dairy herds. Summary measures of production and reproductive performance, details of soil, moss mineral concentrations, and temperature and rainfall measurements at each herd location were available for the period September 2001 to August 2009. A Bayesian mixed-effects regression model including spatial and non-spatial heterogeneity terms was developed to quantify associations between hypothesi...

Hospital Surge Capacity for an Influenza Pandemic in the Triangle Region of North Carolina
Publication date: Available online 8 July 2019Source: Spatial and Spatio-temporal EpidemiologyAuthor(s): Rachel L. Woodul, Paul L. Delamater, Michael EmchAbstractThis research investigates the geographic aspects of health care delivery in the event of a sudden increase in the need for care. We constructed an integrated disease outbreak and surge capacity model to evaluate the ability of a region's healthcare system to provide care in the event of a pandemic. In a case study, we implement the model to investigate how an influenza pandemic similar to the 1918 Spanish Flu pandemic would affect the population of the Raleigh-Du...

Density of Low-Barrier Opioid Agonist Clinics and Risk of Non-Fatal Overdose During a Community-Wide Overdose Crisis: A Spatial Analysis
ConclusionThis study found that higher availability of methadone clinics was associated with decreased odds of living within OD clusters. (Source: Spatial and Spatio-temporal Epidemiology)

Bayesian deprivation index models for explaining variation in elevated blood lead levels among children in Maryland
Publication date: Available online 4 July 2019Source: Spatial and Spatio-temporal EpidemiologyAuthor(s): David C. Wheeler, Shyam Raman, Resa M. Jones, Mario Schootman, Erik J. NelsonAbstractLead exposure adversely affects children's health. Exposure in the United States is highest among socioeconomically disadvantaged individuals who disproportionately live in substandard housing. We used Bayesian binomial regression models to estimate a neighborhood deprivation index and its association with elevated blood lead level (EBLL) risk using blood lead level testing data in Maryland census tracts. Our results show the probabilit...

Stability of Activity Space Footprint, Size, and Environmental Features over Six Months
Publication date: Available online 4 July 2019Source: Spatial and Spatio-temporal EpidemiologyAuthor(s): Amber N. Kraft, Kelly K. Jones, Ting-Ti Lin, Stephen A. Matthews, Shannon N. ZenkAbstractAs activity space measures are increasingly used to estimate exposure to environmental determinants of health, little is known about the stability of these measures over time. To test the stability of GPS-derived measures of activity-space footprint, size, and environmental features over time, we compared 14-day measures at baseline and six months later for 35 adults in a large city. Activity-space measures were based on convex hull...

Analysis of Racial Differences in Hospital Stays in the Presence of Geographic Confounding
Publication date: Available online 5 July 2019Source: Spatial and Spatio-temporal EpidemiologyAuthor(s): Melanie L. Davis, Brian Neelon, Paul J. Nietert, Lane F. Burgette, Kelly J. Hunt, Andrew B. Lawson, Leonard E. EgedeAbstractUsing recent methods for spatial propensity score modeling, we examine differences in hospital stays between non-Hispanic black and non-Hispanic white veterans with type 2 diabetes. We augment a traditional patient-level propensity score model with a spatial random effect to create a matched sample based on the estimated propensity score. We then use a spatial negative binomial hurdle model to esti...

Spatial distribution of inequalities in end-stage renal disease in the United States
Publication date: Available online 28 May 2019Source: Spatial and Spatio-temporal EpidemiologyAuthor(s): Fırat BilgelAbstractThis paper assesses the locally varying effects of socioeconomic, racial and morbidity-related geographic heterogeneity on end-stage renal disease prevalence in the contiguous United States. Employing an exploratory spatial data analysis and a geographically weighted Poisson regression that takes into account spatial nonstationarity, spatial autocorrelation and the nature of count data, findings indicate a striking continental divide in the United States not only in terms of ESRD burden but also in ...

Quantifying geographic regions of excess stillbirth risk in the presence of spatial and spatio-temporal heterogeneity
Publication date: Available online 9 April 2019Source: Spatial and Spatio-temporal EpidemiologyAuthor(s): David Zahrieh, Jacob J. Oleson, Paul A. RomittiAbstractMotivated by population-based geocoded data for Iowa stillbirths and live births delivered during 2005-2011, we sought to identify spatio-temporal variation of stillbirth risk. Our high-quality data consisting of point locations of these delivery events allows use of a Bayesian Poisson point process approach to evaluate the spatial pattern of events. With this large epidemiologic dataset, we implemented the integrated nested Laplace approximation (INLA) to fit the ...

Estimating the health impact of air pollution in Scotland, and the resulting benefits of reducing concentrations in city centres
Publication date: Available online 9 April 2019Source: Spatial and Spatio-temporal EpidemiologyAuthor(s): Duncan Lee, Chris Robertson, Colin Ramsay, Colin Gillespie, Gary NapierAbstractAir pollution continues to be a key health issue in Scotland, despite recent improvements in concentrations. The Scottish Government published the Cleaner Air For Scotland strategy in 2015, and will introduce Low Emission Zones (LEZs) in the four major cities (Aberdeen, Dundee, Edinburgh and Glasgow) by 2020. However, there is no epidemiological evidence quantifying the current health impact of air pollution in Scotland, which this paper add...

A Bayesian Spatio-temporal Analysis on Racial Disparities in Hypertensive Disorders of Pregnancy in Florida, 2005-2014
Publication date: Available online 6 April 2019Source: Spatial and Spatio-temporal EpidemiologyAuthor(s): Hui Hu, Hong Xiao, Yi Zheng, Bo (Bonnie) YuAbstractDisparities in hypertensive disorders of pregnancy (HDP) exist among racial and ethnic groups in the US. However, little is known about spatio-temporal variations in HDP disparities. We used a Bayesian hierarchical regression approach to investigate spatio-temporal variations in HDP disparities from 2005 to 2014. County-level variation was firstly examined, followed by census tract-level variation assessment in counties where high HDP disparities were observed. A signi...
