Assessing whether long-term exposure to air pollution increases the severity of COVID-19 health outcomes, including death, is an important public objective. Limitations in data availability and quality remain obstacles conducting conclusive studies on this topic. At present, publicly available outcome for representative populations are only as area-level counts. Therefore, outcomes using these must use ecological regression analysis, which precludes controlling individual-level risk factors....
United States government scientists estimate that COVID-19 may kill tens of thousands Americans. Many the pre-existing conditions increase risk death in those with are same diseases affected by long-term exposure to air pollution. We investigated whether average fine particulate matter (PM 2.5 ) is associated an increased States.A nationwide, cross-sectional study using county-level data.COVID-19 counts were collected for more than 3,000 counties (representing 98% population) up April 22,...
United States government scientists estimate that COVID-19 may kill tens of thousands Americans. Many the pre-existing conditions increase risk death in those with are same diseases affected by long-term exposure to air pollution. We investigated whether average fine particulate matter (PM2.5) is associated an increased States. collected data for more than 3,000 counties (representing 98% population) up April 22, 2020. fit negative binomial mixed models using county-level deaths as outcome...
Black Americans are exposed to higher annual levels of air pollution containing fine particulate matter (particles with an aerodynamic diameter ≤2.5 μm [PM
There is growing concern that phthalate exposures may have an impact on child neurodevelopment. Prenatal exposure to phthalates has been linked with externalizing behaviors and executive functioning defects suggestive of attention-deficit hyperactivity disorder (ADHD) phenotype.We undertook investigation into whether prenatal was associated clinically confirmed ADHD in a population-based nested case-control study the Norwegian Mother Child Cohort (MoBa) between years 2003 2008.Phthalate...
E-cigarettes are generally thought of as a safer smoking alternative to traditional cigarettes. However, little is known about the effects e-cigarette liquids (e-liquids) on lung. Since over 7,000 unique flavors have been identified for purchase in United States, our goal was conduct screen that would test whether different flavored e-liquids exhibited toxicant profiles. We tested 13 [with nicotine and propylene glycol/vegetable glycerin (PG/VG) serving controls] lung epithelial cell line...
Abstract Hurricanes and other tropical cyclones have devastating effects on society. Previous case studies quantified their impact some health outcomes for particular cyclones, but a comprehensive assessment over longer periods is currently missing. Here, we used data 70 million Medicare hospitalizations cyclone exposures 16 years (1999–2014). We formulated conditional quasi-Poisson model to examine how exposure (days greater than Beaufort scale gale-force wind speed; ≥34 knots) affect 13...
<h3>Importance</h3> Tropical cyclones have a devastating effect on society, but comprehensive assessment of their association with cause-specific mortality over multiple years study is lacking. <h3>Objective</h3> To comprehensively evaluate the county-level tropical cyclone exposure and death rates from various causes in US. <h3>Design, Setting, Participants</h3> A retrospective observational using Bayesian conditional quasi-Poisson model to examine how were associated monthly rates. Data...
Flooding greatly endangers public health and is an urgent concern as rapid population growth in flood-prone regions more extreme weather events will increase the number of people at risk. However, exhaustive analysis mortality following floods has not been conducted. Here we used 35.6 million complete death records over 18 years (2001–2018) from National Center for Health Statistics United States, highly resolved flood exposure data a Bayesian conditional quasi-Poisson model to estimate...

Human populations, including susceptible subpopulations such as pregnant women and their fetuses, are continuously exposed to phthalates. Phthalates may affect the thyroid hormone system, causing concern for pregnancy health, birth outcomes child development. Few studies have investigated joint effect of phthalates on function in women, although they present a mixture with highly inter-correlated compounds. Additionally, no if key nutrient iodine, modifies these relationships. In this study,...
Investigating the health impacts of wildfire smoke requires data on people's exposure to fine particulate matter (PM
In an analysis of data collected over a 10-year period from four emergency departments, short-term exposures to ambient heat and particulate air pollution were associated with increased utilization radiography CT but not US or MRI.
U.S. Environmental Protection Agency (EPA) air quality (AQ) monitors, the "gold standard" for measuring pollutants, are sparsely positioned across Low-cost sensors (LCS) increasingly being used by public to fill in gaps AQ monitoring; however, LCS not as accurate EPA monitors. In this work, we investigate factors impacting differences between an individual's true (unobserved) exposure pollution and reported their nearest instrument (which could be either or monitor). We use simulations based...
Little epidemiologic research has focused on pollution-related risks in medically vulnerable or marginalized groups. Using a nationwide 50% random sample of 2008-2016 Medicare Part D-eligible fee-for-service participants the United States, we identified cohort with high-risk conditions for cardiovascular and thromboembolic events (CTEs) linked individuals seasonal average zip-code-level concentrations fine particulate matter (particulate an aerodynamic diameter ≤ 2.5 μm (PM2.5)). We assessed...
To assess the association between ambient heat and all-cause cause-specific emergency department (ED) visits acute hospitalizations among Medicare beneficiaries in conterminous United States.
Most causal inference studies rely on the assumption of overlap to estimate population or sample average effects. When data suffer from non-overlap, estimation these estimands requires reliance model specifications due poor support. All existing methods address such as trimming down-weighting in regions support, change estimand so that cannot be made underlying population. In environmental health research settings where study results are often intended influence policy, population-level may...
Prenatal phthalate exposure has been linked with altered neurodevelopment, including externalizing behaviors and attention-deficit hyperactivity disorder (ADHD). However, the implicated metabolite, neurobehavioral endpoint, child sex have not always consistent across studies, possibly due to heterogeneity in neurodevelopmental instruments. The complex set of findings may be synthesized using executive function (EF), a construct cognitive processes that facilitate ongoing goal-directed...
