Oilfield-adjacent communities often report symptoms such as headaches and/or asthma. Yet, little data exists on health experiences and exposures in urban environments with oil and gas development. In partnership with Promotoras de Salud (community health workers), we gathered household surveys nearby two oil production sites in Los Angeles. We tested the capacity of low-cost sensors for localized exposure estimates. Bilingual surveys of 205 randomly sampled residences were collected within two 1500 ft. buffer areas (West Adams and University Park) surrounding oil development sites. We used a one-sample proportion test, comparing overall rates from the California Health Interview Survey (CHIS) of Service Planning Area 6 (SPA6) and Los Angeles County for variables of interest such as asthma. Field calibrated low-cost sensors recorded methane emissions. Physician diagnosed asthma rates were reported to be higher within both buffers than in SPA6 or LA County. Asthma prevalence in West Adams but not University Park was significantly higher than in Los Angeles County. Respondents with diagnosed asthma reported rates of emergency room visits in the previous 12 months similar to SPA6. 45% of respondents were unaware of oil development; 63% of residents would not know how to contact local regulatory authorities. Residents often seek information about their health and site-related activities. Low-cost sensors may be useful in highlighting differences between sites or recording larger emission events and can provide localized data alongside resident-reported symptoms. Regulatory officials should help clarify information to the community on methods for reporting health symptoms. Our community-based participatory research (CBPR) partnership supports efforts to answer community questions as residents seek a safety buffer between sensitive land uses and active oil development.

Interventions aimed at the prevention of falls should focus on maintaining and improving general health and promoting physical activity among older adults.

The objectives of this research were to 1) summarize the available evidence on the impact of hearing loss on quality of life (QOL) among U.S. active-duty service members, 2) describe the QOL instruments that have been used to quantify the impact of hearing loss on quality of life, 3) examine national population-level secondary databases and report on their utility for studying the impact of hearing loss on QOL among active-duty service members, and 4) provide recommendations for future studies that seek to quantify the impact of hearing loss in this population. There is a lack of literature that addresses the intersection of hearing impairment, the military population, and quality of life measures. For audiological research, U.S. military personnel offer a unique research population, as they are exposed to noise levels and blast environments that are highly unusual in civilian work settings and can serve as a model population for studying the impact on QOL associated with these conditions. Our team recommends conducting a study on the active-duty service member population using a measurement instrument suitable for determining decreases in QOL specifically due to hearing loss.

The goal of this multiphased research is to develop methods to comprehensively determine the economic impact of hearing impairment and noise-induced hearing injury among active duty U.S. Service Members. Several steps were undertaken to develop a framework and model for economic burden analysis: (1) a literature review identifying studies reporting the cost of health conditions and injuries in the Department of Defense, (2) consultation with a panel of subject matter experts who reviewed these cost items, and (3) discussions with DoD data stewards and review of relevant data dictionaries and databases. A Markov model was developed to represent the cumulative economic effect of events along the career span, such as retraining after hearing impairment and injury, by synthesizing inputs from various sources. The model, as developed and proposed in this study, will be a valuable decision-making tool for the DoD to identify high-risk groups, take proactive measures, and develop focused education, customized equipping, and return-to-duty and reintegration programs, thereby maximizing the retention of skilled, experienced, and mission-ready Service Members.

Although studies have examined the relation between military-related noise and hearing, comprehensive data to calculate rates of hearing loss across all Services and to determine economic impact are lacking. The goal of the multiphase Department of Defense (DoD) Epidemiologic and Economic Burden of Hearing Loss (DEEBoHL) project is to examine rates of hearing impairment and noise-induced hearing injury, relevant noise exposures, and to determine the economic burden of these outcomes to the DoD and Service Members. The DoD Hearing Center of Excellence is supporting the following Phase I specific aims, among active duty Service Members to (1) calculate rates of hearing impairment and noise-induced hearing injury, and (2) develop a framework for the DoD to conduct comprehensive economic burden studies for hearing impairment and noise-induced hearing injury. The study is led by a multidisciplinary team from The University of Texas School of Public Health, The University of Texas Health Science Center at San Antonio, and The Geneva Foundation, with guidance from experts who make up the study advisory board. In this article, we focus on an overview of the DEEBoHL study, the methods for the first aim of this effort, and describe future plans for the study.

The public health consequences and environmental injustices stemming from oil development in densely populated urban environments are of increasing concern to residents surrounding oil and gas development facilities. The Los Angeles Basin contains one of the highest concentrations of crude oil in the world, with over 5,000 active oil wells in Los Angeles County. Oil was struck in the Los Angeles Basin in the 1890s and reached its production peak in the 1930s, making up nearly half of California's oil production at the time and nearly one quarter of the world's oil output. Oil development shaped, and oftentimes dominated, Los Angeles's development as a global city (Pratt et al. 2014). Today, although oil wells are scattered across the city and county, it is poor communities and communities of color that live closer to wells, have outdated emissions equipment, and have the oil fields near to homes uncovered rather than enclosed (Reyes 2016). The legacy of decision making over oil drilling in Los Angeles is that thousands of active wells in the greater Los Angeles area are located among a dense population of more than 10 million people. Seventy percent of active oil wells in the city are located within 1,500 feet (457 meters) of a home or sensitive land use such as a school, playground, or hospital-places where people live, work, and play (Sadd and Shamasunder 2015). Oil development in Los Angeles grew side by side with urbanization. In some communities, such as the South Los Angeles neighborhood of West Adams, residences were destroyed to make room for oil development operations, and
