A mortality study of workers employed between 1944 and 1977 at an electrical capacitor manufacturing plant where polychlorinated biphenyls (PCBs), chlorinated naphthalenes, and other chemicals were used was undertaken. Age, gender, and calendar year-adjusted standardized mortality ratios (SMRs) were calculated for 2885 white workers. Total mortality and(More)
BACKGROUND Studies have shown associations of diabetes and endogenous hormones with exposure to a wide variety of organochlorines. We have previously reported positive associations of polychlorinated biphenyls (PCBs) and inverse associations of selected steroid hormones with diabetes in postmenopausal women previously employed in a capacitor manufacturing(More)
There is an increasing body of literature showing associations of organochlorine exposure with risk of diabetes and insulin resistance. Some studies suggest that associations differ by gender and that diabetes risk, in turn, may be affected by endogenous steroid hormones. This report examines the relationships of serum PCBs and endogenous hormones with(More)
BACKGROUND Asthma mortality rates in poor communities of Chicago are among the highest in the country. Possible explanations include increased asthma prevalence, increased severity, and suboptimal health care. OBJECTIVE To estimate the prevalence of asthma and asthma-related symptoms among inner-city kindergarten children, and to characterize their burden(More)
BACKGROUND Prevalence of asthma in developed countries increased between the 1970s and the 1990s. One factor that might contribute to the trends in asthma is the increased use of acetaminophen vs aspirin in children and pregnant women. OBJECTIVE To examine relationships between in utero exposure to acetaminophen and incidence of respiratory symptoms in(More)
The most effective means of educating children with asthma and their families has not been clearly demonstrated in previous studies. Peer education is uniquely suited to the complex problems encountered in underserved populations. The purpose of this study was to show the feasibility of delivering a peer education program for children with asthma and the(More)
BACKGROUND Asthma mortality rates in Chicago are among the highest in the United States, with substantially greater rates in poor and minority populations. How much of the differential can be attributed to differences in prevalence versus severity or access to care has not been determined. OBJECTIVE To examine rates of asthma prevalence, severity, and(More)
Recent studies suggest that psychosocial factors may contribute to asthma. We examined associations of stressful life events with asthma prevalence and morbidity among Chicago adolescents. Self-reported asthma, measures of asthma morbidity, and 15 life events were collected from 2026 seventh to ninth grade students from 34 Chicago Catholic schools as part(More)
Asthma morbidity and mortality are disproportionately high in low-income minority populations. Variations in environmental exposures, stress, and access to appropriate health care all contribute to these disparities. The complex nature of asthma with strong contributions from environmental, psychosocial, and biological factors suggest that community-based(More)
OBJECTIVES Changes in breast and gastric cancers and coronary artery disease among people of Polish descent after migration to the United States suggest there may be potentially modifiable factors affecting incidence of these diseases. We examined relationships of dietary factors associated with these diseases with stage of migration among Polish women in(More)
