Comparing Machine Learning to Regression Methods for Mortality Prediction Using Veterans Affairs Electronic Health Record Clinical Data
BACKGROUND: It is unclear whether machine learning methods yield more accurate electronic health record (EHR) prediction models compared with traditional regression methods. OBJECTIVE: The objective of this study was to compare machine learning and traditional regression models for 10-year mortality prediction using EHR data. DESIGN: This was a cohort study. SETTING: Veterans Affairs (VA) EHR data. PARTICIPANTS: Veterans age above 50 with a prima…
Chronic disease burden predicts food insecurity among older adults
Objective Increased out-of-pocket health-care expenditures may exert budget pressure on low-income households that leads to food insecurity. The objective of the present study was to examine whether older adults with higher chronic disease burden are at increased risk of food insecurity. Design Secondary analysis of the 2013 Health and Retirement Study (HRS) Health Care and Nutrition Study (HCNS) linked to the 2012 nationally representative HRS. …
The Effect of Neonatal Intensive Care Level and Hospital Volume on Mortality of Very Low Birth Weight Infants
OBJECTIVE: To determine the adjusted effect of hospital level of care and volume on mortality of very low birth weight (VLBW) infants in the state of California, where deregionalization of perinatal care has occurred. RESEARCH DESIGN: Secondary data analysis of California maternal-infant hospital discharge data from 1997 to 2002 was performed. Logistic regression was used to evaluate the odds of mortality among VLBW infants by hospital level of n…
The Effect of Urban Street Gang Densities on Small Area Homicide Incidence in a Large Metropolitan County, 1994–2002
The presence of street gangs has been hypothesized as influencing overall levels of violence in urban communities through a process of gun-drug diffusion and cross-type homicide. This effect is said to act independently of other known correlates of violence, i.e., neighborhood poverty. To test this hypothesis, we independently assessed the impact of population exposure to local street gang densities on 8-year homicide rates in small areas of Los …

Differences in Cause-Specific Mortality Between Latino and White Adults
BACKGROUND: Understanding differences in cause-specific mortality between Latinos and whites is important for targeting future public health interventions and research aimed at eliminating health disparities. OBJECTIVES: We sought to determine the contribution of specific causes of death to Latino-white differences in mortality. RESEARCH DESIGN: Using nationally representative data, we estimated cause-specific mortality risks, which were then use…
Contribution of Major Diseases to Disparities in Mortality
BACKGROUND: Mortality from all causes is higher for persons with fewer years of education and for blacks, but it is unknown which diseases contribute most to these disparities. METHODS: We estimated cause-specific risks of death from data from the National Health Interview Survey conducted from 1986 through 1994 and from linked vital statistics. Using these risk estimates, we calculated potential years of life lost and potential gains in life exp…
