Recent advances in geographic information systems software and multilevel methodology provide opportunities for more extensive characterization of "at-risk" populations in epidemiologic studies. The authors used age-restricted, geocoded data from the all-African-American Jackson Heart Study (JHS), 2000-2004, to demonstrate a novel use of the Lorenz curve and Gini coefficient to determine the representativeness of the JHS cohort to the African-American population in a geographic setting.

Neighborhood Disadvantage, Poor Social Conditions, and Cardiovascular Disease Incidence Among African American Adults in the Jackson Heart Study.
TLDR
Worse neighborhood economic and social conditions may contribute to increased risk of CVD among African American women and policies directly addressing these issues may alleviate the burden ofCVD in this group.
Residential Proximity to Traffic-Related Pollution and Atherosclerosis in 4 Vascular Beds Among African-American Adults: Results From the Jackson Heart Study.
TLDR
The results highlight the need to consider residential proximity to roadways as a potential cardiovascular disease risk factor for blacks and suggest an association in the carotid vascular beds but not the coronary, abdominal, or peripheral vascular beds.
Residential Proximity to Traf fi c-Related Pollution and Atherosclerosis in 4 Vascular Beds Among African-American Adults: Results From the Jackson Heart Study
TLDR
The results highlight the need to consider residential proximity to roadways as a potential cardiovascular disease risk factor for blacks and observe an association in the carotid vascular beds but not the coronary, abdominal, or peripheral vascular beds.
Life Course Socioeconomic Position and Subclinical Disease: The Jackson Heart Study.
TLDR
Subclinical disease markers were patterned by adult SEP measures among African Americans, and measures of childhood SEP were not consistently associated with subclinical disease measures other than a positive association between material resources and CIMT.
Contribution Residential Proximity to Traf fi c-Related Pollution and Atherosclerosis in 4 Vascular Beds Among African-American Adults : Results From the Jackson Heart Study
TLDR
The results highlight the need to consider residential proximity to roadways as a potential cardiovascular disease risk factor for blacks and observe an association in the carotid vascular beds but not the coronary, abdominal, or peripheral vascular beds.
A review of spatial methods in epidemiology, 2000-2010.
TLDR
The huge growth in spatial epidemiology is documented, the tools that have been employed are summarized, and emerging areas that are likely to be important to future spatial analysis in public health are noted.
Residential distance to major roadways and cardiac structure in African Americans: cross-sectional results from the Jackson Heart Study
TLDR
It is found that residential distance to roads may be associated with LV end-systolic diameter, a marker of systolic dysfunction, in this cohort of African Americans, suggesting a potential mechanism by which exposure to traffic pollution increases the risk of HF.
Using the Lorenz Curve to Characterize Risk Predictiveness and Etiologic Heterogeneity.
TLDR
It is demonstrated that, although the Lorenz curve represents the distribution of predicted risks in a population at risk for the disease, in fact it can be estimated from a case-control study conducted in the population without the need for information on absolute risks.
Neighborhood Disadvantage, Neighborhood Safety and Cardiometabolic Risk Factors in African Americans: Biosocial Associations in the Jackson Heart Study
TLDR
Neighbourhood socioeconomic disadvantage and perceived safety should be considered as targets for intervention to reduce cardiometabolic risks among African Americans.

Methods for Retrospective Geocoding in Population Studies: The Jackson Heart Study
TLDR
The results indicate that retrospectively developing a reliable GIS for a large, epidemiological study is feasible and some of the challenges in retrospectively creating a GIS are described and practical tips that enhanced the success are provided.
Recruiting African-American research participation in the Jackson Heart Study: methods, response rates, and sample description.
TLDR
The JHS experiences provide useful lessons for observational epidemiological studies recruiting African-American research participation and co-participation of researchers and researched in study design and realistic evidence of community benefit were crucial to recruitment success.
Geographic distribution of pediatricians in the United States: an analysis of the fifty states and Washington, DC.
TLDR
The distribution of pediatricians does not parallel the distribution of the child population in the US, nor has this distribution changed substantially in spite of a 38.6% increase in the PCPR, and Pediatricians tend to concentrate in states with high per capita income and inStates with a larger number of residency training positions.
Characterizing exposure-disease association in human populations using the Lorenz curve and Gini index.
TLDR
The present paper discusses the possibility of using the summary index of the Lorenz curve, the Gini index, as an alternative measure of exposure-disease association and it is found that this index can be interpreted in several ways and is a promising alternative as a fundamental measure in epidemiology.
Disease mapping and spatial regression with count data.
TLDR
A new method for picking prior distributions is introduced, and a number of refinements of previously used models are proposed, including ecological bias, mutual standardization, and choice of both spatial model and prior specification.
The Atherosclerosis Risk in Communities (ARIC) Study: design and objectives. The ARIC investigators.
TLDR
In each of four US communities, 4,000 adults aged 45-64 years will be examined twice, three years apart, to investigate the etiology of atherosclerosis and its clinical sequelae and variation in cardiovascular risk factors, medical care, and disease by race, sex, place, and time.
Empirical Bayes estimates of age-standardized relative risks for use in disease mapping.
TLDR
A new approach using empirical Bayes estimation is proposed to map incidence and mortality from diseases such as cancer and the resulting estimators represent a weighted compromise between the SMR, the overall mean relative rate, and a local mean of the relative rate in nearby areas.
Inequality in the geographical distribution of general practitioners in England and Wales 1974-1995
TLDR
Inequality in the distribution of GPs in 1995 was less than inequality in other primary care resources, but greater than inequalities in disposable income, SMRs, primary school expenditure, and hospital and community health services expenditure.
