Summary: The Imperial County Community Air Monitoring Network (the Network) is a collaborative group of community, academic, nongovernmental, and government partners designed to fill the need for more detailed data on particulate matter in an area that often exceeds air quality standards. employs community-based environmental monitoring process which community researchers have specific, well-defined roles as part equitable partnership also includes shared decision-making determine study...
The Imperial County Community Air Monitoring Network was developed as part of a community-engaged research study to provide real-time particulate matter (PM) air quality information at high spatial resolution in County, California. network augmented the few existing regulatory monitors and increased monitoring near susceptible populations. Monitors were both calibrated field validated, key component evaluating data produced by community network. This paper examines performance customized...

Background: Ambient air pollution and tuberculosis (TB) have an impact on public health worldwide, yet associations between the two remain uncertain. Objective: We determined of residential traffic mortality during treatment active TB. Methods: From 2000–2012, we enrolled 32,875 patients in California with TB followed them throughout treatment. obtained patient data from Tuberculosis Registry calculated volumes densities 100- to 400-m radius buffers around addresses. used Cox models...
Air monitoring networks developed by communities have potential to reduce exposures and affect environmental health policy, yet there been few performance evaluations of these sensors in the field. We a network over 40 air Imperial County, CA, which is delivering real-time data local on levels particulate matter. report here Network date comparing low-cost sensor readings regulatory monitors for 4 years operation (2015–2018) network-wide basis. Annual mean PM10 did not differ statistically...
Air pollution continues to be a global public health threat, and the expanding availability of small, low-cost air sensors has led increased interest in both personal crowd-sourced monitoring. However, date, few monitoring networks have been developed with scientific rigor or continuity needed conduct surveillance inform policy. In Imperial County, California, near U.S./Mexico border, we used collaborative, community-engaged process develop community network that attains required for...
Significant illness is associated with biological contaminants in drinking water, but little known about health effects from low levels of chemical contamination water. To examine these epidemiological studies, the sources water study populations need to be known.The California Environmental Health Tracking Program developed an online application that would collect data on geographic location public system (PWS) customer service areas California, which then could linked demographic and...
Conventional regulatory air quality monitoring sites tend to be sparsely located. The availability of lower-cost pollution sensors, however, allows for their use in spatially dense community networks, which can operated by various stakeholders, including concerned residents, organizations, academics, or government agencies. Networks many monitors have the potential fill spatial gaps between existing government-operated sites. One benefit finer scale might ability discern elevated episodes...
An understudied social process that may determine variable HIV risk, testing, and linkage to care is geographic mobility, including immigration as well short-term especially among sexual minority populations. We aimed assess how mobility over the lifecourse between Latin America U.S., within was linked risk health behaviors Latinx migrant men who have sex with (MSM) in San Bernardino County, California. Qualitative analysis of 16 semi-structured interviews revealed four major domains...
Objective. Neighborhood characteristics have been shown to influence lifestyle behaviors. Here we characterized alcohol outlet density in Los Angeles County, California, and Hawaii assessed the association of with self-reported intake Multiethnic Cohort. Method. Participants (n=178,977) had their addresses geocoded, at cohort entry (1993-1996), appended block group-level densities (on- off-premises). Multinomial logistic regression was performed assess between on- off-premise by each state....
This paper describes the use of citizen science-derived data for creation a land-use regression (LUR) model particulate matter (PM2.5 and PMcoarse) vulnerable community in Imperial County, California (CA), near United States (US)/Mexico border. Data from County Community Air Monitoring Network monitors were calibrated added to LUR, along with meteorology land use. PM2.5 PMcoarse predicted across county at monthly timescale. Model types compared by cross-validated (CV) R2 root-mean-square...
Initiated in response to community concerns about high levels of air pollution and asthma, the Imperial County Community Air Monitoring Project was conducted as a collaboration between community-based organization, non-governmental environmental health program, academic researchers. This community-engaged research project aimed produce real-time, community-level quality information through establishment monitoring network (CAMN) 40 low-cost particulate matter (PM) monitors County,...
To describe vaccine and booster uptake by neighborhood-level factors in California.We examined trends COVID-19 vaccination up to September 21, 2021, boosters March 29, 2022 using data from the California Department of Public Health. Quasi-Poisson regression was used model association between fully vaccinated boosted among ZIP codes. Sub-analyses on rates were compared 10 census regions.In a minimally adjusted model, higher proportion Black residents associated with lower (HR = 0.97; 95%CI:...
Abstract Background: Women Informed to Screen Depending on Measures of risk (WISDOM) is a preference-tolerant, pragmatic clinical trial comparing the safety and morbidity personalized risk-based annual breast cancer screening. Environmental factors are not considered in WISDOM’s assessment. Geocoded residential addresses were used understand whether relationship between area deprivation, exposure environmental toxins, race ethnicity exists within cohort. Methods: The at time study entry...
Abstract Background: African American (AA) men are more than twice as likely to die of prostate cancer (PC) compared non-Hispanic White in the US. Among AA men, we examined survival after PC diagnosis by neighborhood-level structural racism and whether its effects mediated neighborhood socioeconomic status (nSES). Methods: We pooled data for 133,241 diagnosed with from 2000-2013 ten population-based registries across eight states (CA, Detroit, FL, GA, LA, NJ, NY, TX) RESPOND Study (Research...
Abstract Background: The COVID-19 pandemic and associated shutdowns disrupted healthcare access resulted in decreased cancer screenings. Cancer diagnosis delays have concerning downstream effects on late-stage cancer, especially for marginalized populations. Methods: study population included 349,458 adults the California Registry diagnosed with between January 2019 December 2021, during which experienced two stay-at-home orders. We examined percentage of (III–IV) diagnoses across five...
Introduction: Trees can mitigate air pollution, but health benefits remain unclear.
