Abstract - Covariates may affect continuous responses differently at various points of the response distribution. For example, some exposure might have minimal impact on conditional means, whereas it might lower conditional 10th percentiles sharply. Such differential effects can be important to...
Author(s): Miranda, M.L., Anthopolos, R., Edwards, S.E
Summary: background - Seasonal variation in poor pregnancy outcomes has not received the same level of research attention and rigor as has thewell-established seasonal variation in births.
Author(s): Maxson, P., Miranda, M.L.
Abstract: OBJECTIVES - We explore the psychosocial, demographic, and maternal characteristics across wanted, mistimed, and unwanted pregnancies.
Author(s): Miranda, M.L., Anthopolos, R., Hastings, D
Abstract: Background - Aviation gasoline, commonly referred to as avgas, is a leaded fuel used in small aircraft. Recent concern about the effects of lead emissions from planes has motivated the U.S. Environmental Protection to consider regulating leaded avgas.
Author(s): M.L. Miranda, M.A. Overstreet Galeano, B. Hale, and W.R. Thomann
Abstract: BACKGROUND - Recent studies suggest that exposure to mold in damp buildings is an important environmental risk factor for childhood respiratory illness. One potential source of a damp home, is crawl space construction. A poorly constructed crawl space not only presents the possibility of...
Author(s): Neelon, B., Swamy, G.K., Burgette, L.F., Miranda, M.L.
Abstract - Maternal hypertension is a major contributor to adverse pregnancy outcomes, including preterm birth (PTB) and low birth weight (LBW). Although several studies have explored the relationship between maternal hypertension and fetal health, few have examined how the longitudinal trajectory...

Abstract

Background: Polybrominated diphenyl ethers (PBDEs) are chemical additives used as flame retardants in commercial products. PBDEs are bioaccumulative and persistent and have been linked to several adverse health outcomes.

Author(s): Miranda, M.L., Edwards, S., Keating, M., Paul, C.
Abstract - This paper assesses whether the Clean Air Act and its Amendments have been equally successful in ensuring the right to healthful air quality in both advantaged and disadvantaged communities in the United States. Using a method to rank air quality established by the American Lung...
Author(s): V.J. Berrocal, A.E. Gelfand, D.M. Holland, J. Burke, and M.L. Miranda
Abstract - In relating pollution to birth outcomes, maternal exposure has usually been described using monitoring data. Such characterization provides a misrepresentation of exposure as (i) it does not take into account the spatial misalignment between an individual's residence and monitoring sites...
Author(s): Gray, S.C., Gelfand, A.E., Miranda, M.L.
Abstract - In environmental health studies air pollution measurements from the closest monitor are commonly used as a proxy for personal exposure. This technique assumes that air pollution concentrations are spatially homogeneous in the neighborhoods associated with the monitors and consequently...
Author(s): Kim, D., Miranda, M.L., Tootoo, J.L., Bradley, P., Gelfand, A.
Abstract - To examine environmental and geologic determinants of arsenic in groundwater, detailed geologic data were integrated with well water arsenic concentration data and well construction data for 471 private wells in Orange County, NC, via a geographic information system. For the statistical...
Author(s): M.L. Miranda, P. Maxson, and D. Kim
Abstract - The achievement gap continues to be an important educational issue, with disadvantaged groups exhibiting poorer school performance. Recently, literature has shown that even very low levels of early lead exposure affect cognitive and academic performance. As individuals at the lower end...
Author(s): Miranda, M.L., Edwards, S.E
Abstract - Recent advances in spatial statistics and geographic information systems provide innovative platforms for diagnosing environmental health problems and for developing interventions. This article discusses when and where spatial techniques can most effectively be deployed to address...
Author(s): M.L. Miranda, D. Hastings, J. Aldy, and W. Schlesinger
Abstract - Nations around the world are considering strategies to mitigate the severe impacts of climate change predicted to occur in the twenty-first century. Many countries, however, lack the wealth, technology, and government institutions to effectively cope with climate change. This study...
Author(s): Miranda, M.L., Edwards, S., Maxson, P.
Abstract - The adverse effects of prenatal mercury exposure, most commonly resulting from maternal fish consumption, have been detected at very low exposure levels. The omega-3 fatty acids found in fish, however, have been shown to support fetal brain and vision development. Using data from a...
Author(s): C.J. Paul and M.L. Miranda
At the beginning of the twenty-first century, key public health issues and challenges have taken centre stage. They range from arsenic in drinking water to asthma among children and adults; from the re-emergence of cholera, to increasing cancer rates and other chronic diseases; from AIDS to malaria...
Author(s): G. Swamy, S. Edwards, A. Gelfand, and M.L. Miranda
Abstract: Background - Studies examining the influence of maternal age and birth order on birthweight have not effectively disentangled the relative contributions of each factor to birthweight, especially as they may differ by race.
Author(s): M. L. Miranda, G. Swamy, S. Edwards, P. Maxson, A. Gelfand, and S. James
SYNOPSIS: Objectives - To better understand disparities in pregnancy outcomes, we analyzed data from North Carolina to determine how the pattern of maternal hypertensive disorders differs among non-Hispanic white (NHW), non-Hispanic black (NHB), and Hispanic women across the range of maternal ages...
Author(s): S. Schwartz, A. Gelfand, and M.L. Miranda
Abstract - Birthweight and gestational age are closely related and represent important indicators of a healthy pregnancy. Customary modeling for birthweight is conditional on gestational age. However, joint modeling directly addresses the relationship between gestational age and birthweight, and...
Author(s): M. L. Miranda, S. Edwards, G. Swamy, C. Paul, and B. Neelon
Abstract - Blood lead among pregnant women, even at modest levels, may impair offspring cognitive development. We examine whether blood lead levels (BLLs) result from current versus historic exposures, among a cohort of pregnant women. Cumulative logit models were used to characterize the...
