BACKGROUND AND OBJECTIVES Although the deleterious effects of air pollution from fossil fuel combustion have been demonstrated in many Western nations, fewer studies have been conducted in Asia. The Public Health and Air Pollution in Asia (PAPA) project assessed the effects of short-term exposure to air pollution on daily mortality in Bangkok, Thailand, and(More)
Several studies have investigated the short-term effects of ambient air pollutants in the development of high blood pressure and hypertension. However, little information exists regarding the health effects of long-term exposure. To investigate the association between residential long-term exposure to air pollution and blood pressure and hypertension, we(More)
OBJECTIVE We studied the evolution of lower respiratory symptoms at 1 month (initial) and 19 months (follow-up) after the collapse of the World Trade Center on September 11, 2001 (9/11). METHODS A total of 1588 New York police officers completed initial self-administered questionnaires. The level of 9/11 exposure and pre-9/11 health was available in 1373.(More)
UNLABELLED Diverse indoor combustion sources contribute to the indoor air environment. To evaluate the effect of these sources on human respiratory health, we examined associations between respiratory conditions and household factors in the 2360 children's fathers (mean = 38.4 years old) and associations between lung function and household factors in 463(More)
BACKGROUND Nonadherence to asthma medications is associated with increased emergency department visits and hospitalizations. If adherence is to be improved, first-fill adherence is the first goal to meet after the physician and patient have decided to begin treatment. Little is known about first-fill adherence with asthma medications and the factors for(More)
BACKGROUND We explored methods to develop uncorrelated variables for epidemiological analysis models. They were used to examine associations between respiratory health outcomes and multiple household risk factors. METHODS We analysed data collected in the Four Chinese Cities Study (FCCS) to examine health effects on prevalence rates of respiratory(More)
BACKGROUND We investigated whether the effect of air pollution on daily mortality is enhanced by high temperatures in Wuhan, China, using data from 2001 to 2004. Wuhan has been called an "oven" city because of its hot summers. Approximately 4.5 million permanent residents live in the 201-km(2) core area of the city. METHOD We used a generalized additive(More)
OBJECTIVE To examine the racial disparity in the association between obesity and asthma in US children and adolescents. METHODS This study was based on a nationally representative, random-digit-dial sample of US households with children less than 18 years of age from the National Survey of Children's Health in 2011/2012 and 2007. The study sample included(More)
In Asia, limited literature has been published on the association between daily mortality and ambient air pollution. We examined the associations of daily cause-specific mortality with daily mean concentrations of particulate matter (PM) with a mass median aerodynamic diameter less than 10 microm (PM(10)) in Wuhan, China using 4 years of data (2001-2004).(More)
BACKGROUND Few studies have assessed the impact of residential home characteristics and home environmental risk factors on respiratory diseases in Chinese women. Therefore, this study sought to determine the association between residential home features, domestic pets, home renovation and other indoor environmental risk factors with respiratory health(More)
