Prevalence of abnormal spirometry and correlates of lung function decline among a population in rural Uganda
Background: Chronic lung disease, which is the third leading cause of death globally, places a disproportionate burden of morbidity and mortality on sub-Saharan Africa, where limited infrastructure results in a lack of understanding of how lung function changes over time, whether it varies among susceptible populations, or whether at-risk individuals could be identified before abnormal lung function develops. To address this gap, we aimed to char…
Documentation of lead exposure-associated comorbidity among 4538 workers in China
Our study demonstrates that comorbidity was prevalent and was dose-dependent among lead exposed workers
Vaping habits and respiratory symptoms using a smartphone app platform
In this smartphone app-based repeated measures study, short-term and relatively long-term use of EC increased the risk of respiratory symptoms
Health Care Disparities Across the Urban‐Rural Divide
PURPOSE: The burden of chronic obstructive pulmonary disease (COPD) is high in rural America. Few studies, however, have examined urban/rural differences in health care access, or racial/ethnic and income disparities stratified by urban/rural residence, among persons with COPD. METHODS: We studied individuals age ≥ 40 years with COPD from the 2018 Behavioral Risk Factor Surveillance System. The primary exposure was "urban" or "rural" county of re…
Aging workforce with reduced work capacity
Israel is experiencing accelerated workforce aging and increasing retirement age that began in the last two decades. Aging workers suffer from increased illness and impairment rates, challenging employing organizations with reduced work capacity. Occupational health practitioners often assist employers in accommodating these challenges. However, insufficient evidence on prognostic factors, organizational practices, and age management tools hamper…
Prevalence and correlates of chronic obstructive pulmonary disease and chronic respiratory symptoms in rural southwestern Uganda
BACKGROUND: The global burden of chronic obstructive pulmonary disease (COPD) disproportionately affects resource-limited settings such as sub-Saharan Africa (SSA), but population-based prevalence estimates in SSA are rare. We aimed to estimate the population prevalence of COPD and chronic respiratory symptoms in rural southwestern Uganda. METHODS: Adults at least 18 years of age who participated in a population-wide census in rural southwestern …
Heart Rate Variability and Performance of Commercial Airline Pilots during Flight Simulations
Pilots undergo a variety of stressors that may affect their performance during all phases of flight. Heart rate variability (HRV) has been considered as a reliable indicator of the parasympathetic and sympathetic activities of human autonomic nervous system, which can be used to characterize the sympathetic stress response of pilots during flight. In this study, thirty active commercial airline pilots were recruited to fly three flight segments i…
Lead in Air in Bangladesh
Previous evaluations of a birth cohort in the Munshiganj District of Bangladesh had found that over 85% of 397 children aged 2−3 years had blood lead concentrations above the United States Centers for Disease Control and Prevention's reference level of 5 μg/dL. Studies in urban areas of Bangladesh have found elevated levels of lead in the air due to industries and remaining contamination from the historic use of leaded gasoline. Sources of lead i…
Increased Risk of Respiratory Mortality Associated with the High-Tech Manufacturing Industry
Global high-tech manufacturers are mainly located in newly industrialized countries, raising concerns about adverse health consequences from industrial pollution for people living nearby. We investigated the ecological association between respiratory mortality and the development of Taiwan's high-tech manufacturing, taking into account industrialization and socioeconomic development, for 19 cities and counties-6 in the science park group and 13 i…
A cross sectional study of anemia and iron deficiency as risk factors for arsenic-induced skin lesions in Bangladeshi women
Considering the magnitude of arsenic exposure and prevalence of anemia in Bangladeshi women, additional research is warranted that identifies the causes of anemia so that effective interventions can be implemented while arsenic remediation efforts continue
Bayesian kernel machine regression for estimating the health effects of multi-pollutant mixtures
Because humans are invariably exposed to complex chemical mixtures, estimating the health effects of multi-pollutant exposures is of critical concern in environmental epidemiology, and to regulatory agencies such as the U.S. Environmental Protection Agency. However, most health effects studies focus on single agents or consider simple two-way interaction models, in part because we lack the statistical methodology to more realistically capture the…
Socioeconomic status is associated with reduced lung function in China
We found cross-sectional evidence of socioeconomic disparities in pulmonary function in Shanghai. These differences increased with age and were partially explained by potentially modifiable exposures
Heart rate variability and DNA methylation levels are altered after short-term metal fume exposure among occupational welders
Acute decline of HRV was observed following exposure to welding PM2.5 and evidence for an epigenetic response of transposable elements to short-term exposure to high-level metal-rich particulates was reported
Effectiveness of the Cigarette Ignition Propensity Standard in Preventing Unintentional Residential Fires in Massachusetts
Objectives. We evaluated the Massachusetts Fire Safe Cigarette Law’s (FSCL’s) effectiveness in preventing residential fires. Methods. We examined unintentional residential fires reported to the Massachusetts Fire Incident Reporting System from 2004 to 2010. We analyzed FSCL effect on the likelihood of cigarette- versus noncigarette-caused fires and effect modification by fire scenario factors by using an interrupted time series regression model. …
Effect of Qigong on quality of life
The results suggest that Waitankung exercising is significantly associated with health-related quality of life. Waitankung may serve as an exercise choice for middle-aged and older people to improve overall quality of life
Second-hand smoke and chronic bronchitis in Taiwanese women
These findings indicate that, besides cigarette smoking, exposure to SHS is a major risk factor for chronic bronchitis in Taiwanese women

Knee Pain and Driving Duration
Objectives. We explored a postulated association between daily driving time and knee pain. Methods. We used data from the Taxi Drivers’ Health Study to estimate 1-year prevalence of knee pain as assessed by the Nordic musculoskeletal questionnaire. Results. Among 1242 drivers, the prevalence of knee pain, stratified by duration of daily driving (≤ 6, > 6 through 8, > 8 through 10, and > 10 hours), was 11%, 17%, 19%, and 22%, respectively. Compare…
Occupational health in the People's Republic of China
China's drive to modernize its economy will produce new occupational health problems even as it resolves earlier ones. Well aware of this, Chinese occupational health experts are intensifying efforts to improve workers' health and establish a modern occupational health program. Occupational lung disease, occupational cancer, heavy metal poisoning, industrial chemical poisoning, and physical factor-induced diseases (noise and heat) have all been t…
