Epidemiologic studies have demonstrated an association between acute exposure to ambient fine particles and both mortality morbidity. Less is known about the relative impacts of specific chemical constituents particulate matter<2.5 microm in aerodynamic diameter (PM2.5) on hospital admissions.This study was designed estimate risks PM2.5 several species admissions for respiratory diseases among children.We obtained data daily counts hospitalizations children<19 <5 years age total...
The association between temperature and mortality has been widely researched, although the morbidity less studied. We examined mean daily apparent emergency room (ER) visits in California.We used a time-stratified case-crossover design, restricting our data to warm seasons of 2005-2008 16 climate zones. study population included cases residing within 10 km meteorologic monitors. Conditional logistic regression models with were applied by zone; these then combined meta-analyses estimate...
With temperatures expected to increase because of climate change, it is essential study the health outcomes elevated temperature in vulnerable populations, such as expectant mothers. In this study, authors estimated association between heat and humidity, measured by apparent temperature, preterm delivery. They conducted a case-crossover analysis almost 60,000 births spanning 16 counties California that occurred from 1999 2006 May September. The identified cases birth state registry births,...
Several investigators have documented the effect of temperature on mortality, although fewer studied its impact morbidity. In addition, little is known about effectiveness mitigation strategies such as use air conditioners (ACs). The authors investigated association between and hospital admissions in California from 1999 to 2005. They also determined whether AC ownership usage, assessed at zip-code level, mitigated this association. Because unique spatial pattern income climate California,...
The association between ambient temperature and morbidity has been explored previously. However, the mental health-related outcomes, including violence self-harm, remains relatively unexamined. For period 2005-2013, we obtained daily counts of emergency room visits involving injuries with an external cause for 16 California climate zones from Office Statewide Health Planning Development combined them data on mean apparent temperature, a combination humidity. Using Poisson regression models,...
BackgroundLiving near traffic has been associated with asthma and other respiratory symptoms. Most studies, however, have conducted in areas high background levels of ambient air pollution, making it challenging to isolate an independent effect traffic. Additionally, most investigations used surrogates exposure, few measured pollutants directly as part the study.ObjectiveWe a cross-sectional study current symptoms children (n = 1,080) living at varying distances from high-traffic roads San...
Studies have explored ozone's connection to asthma and total respiratory emergency department visits (EDVs) but neglected other specific diagnoses despite hypotheses relating ozone infections allergic responses.We examined relationships between EDVs for visits, including specifically acute (ARI), asthma, pneumonia, chronic obstructive pulmonary disease (COPD), upper tract inflammation (URTI).We conducted a multi-site time-stratified case-crossover study of exposures approximately 3.7 million...
Recent studies have linked elevated apparent temperatures with adverse birth outcomes, such as preterm delivery, but other outcomes not been well studied. We examined 8,510 fetal deaths (≥20 weeks' gestation) to estimate their association mean temperature, a combination of temperature and humidity, during the warm season in California (May-October) from 1999 2009. Mothers whose residential zip codes were within 10 km meteorological monitor included. Meteorological data provided by Irrigation...
Studies have reported associations between long-term air pollution exposures and cardiovascular mortality. The biological mechanisms connecting them remain uncertain.We examined of fine particles (PM2.5) ozone with serum markers disease risk in a cohort midlife women. We obtained information from women enrolled at six sites the multi-ethnic, longitudinal Study Women's Health Across Nation, including repeated measurements high-sensitivity C-reactive protein, fibrinogen, tissue-type...
Although respiratory disease has been strongly connected to fine particulate air pollution (particulate matter <2.5 μm in diameter (PM2.5)), evidence mixed regarding the effects of coarse particles from 2.5 10 diameter), possibly because greater spatial heterogeneity particles. In this study, we evaluated relationship between and emergency department visits, including common subdiagnoses, 2005 2008 35 California counties. A time-stratified case-crossover design was used help control for...
Few investigations have explored temperature and birth outcomes. In a retrospective cohort study, we examined apparent temperature, combination of relative humidity, term low weight (LBW) among 43,629 full-term LBW infants 2,032,601 normal-weight in California (1999-2013). The Department Public Health provided certificate data, while meteorological data came from the Irrigation Management Information System, US Environmental Protection Agency, National Centers for Information. After...
While many studies have investigated the health effects associated with acute exposure to fine particulate matter (particulate an aerodynamic diameter less than or equal 2.5 μm (PM2.5)), very few considered risks of specific sources PM2.5. We used city-specific source apportionment in 8 major metropolitan areas California from 2005–2009 examine associations source-specific PM2.5 exposures vehicular emissions, biomass burning, soil, and secondary nitrate sulfate emergency department visits...
Recent studies have suggested an association between air pollution and stillbirth. In this California study, we examined the records of 13,999 stillbirths 3,012,270 livebirths occurring 1999 2009. Using a retrospective cohort design logistic regression models, calculated odds stillbirth associated with each pollutant exposure by trimester throughout entire pregnancy. Covariates considered in model included infant sex, maternal demographic characteristics, season last menstrual period,...
Objective: To examine the risk of all-cause and cardiovascular mortality associated with short-term coarse particle exposure in California while addressing issues misclassification by limiting study to those residing near a pollution monitor. Methods: Deaths 15 counties from 1999 2005 were linked particulate monitoring data. Case deaths limited zip code within 20 km We used conditional logistic regression case-crossover design estimate county-specific effects particles. County estimates then...
BackgroundStudies have shown associations between air pollution or traffic exposure and adverse birth outcomes, such as low weight. However, very few studies examined the effect of emissions on spontaneous abortion (SAB).ObjectiveThe goal this study was to determine whether residential vehicular associated with SAB.MethodsPregnant women from a prepaid health plan in California were recruited into prospective cohort 1990–1991. Three measures constructed for 4,979 participants using annual...
Recent studies suggest that air pollutant exposure may increase the incidence of mental health conditions, however research is limited. We examined association between ozone (O 3 ) and fine particles (PM 2.5 emergency department (ED) visits related to outcomes, including psychosis, neurosis, neurotic/stress, substance use, mood/affective, depression, bipolar, schizotypal/delusional, schizophrenia, self-harm/suicide, homicide/inflicted injury, from 2005 through 2013 in California.
