To describe the prevalence and correlates of reports about sensitivities to chemicals, questions about chemical sensitivities were added to the 1995 California Behavior Risk Factor Survey (BRFS). The survey was administered by telephone to 4,046 subjects. Of all respondents, 253 (6.3%) reported doctor-diagnosed "environmental illness" or "multiple chemical sensitivity" (MCS) and 643 (15.9%) reported being "allergic or unusually sensitive to everyday chemicals." Sensitivity to more than one type of chemical was described by 11.9% of the total sample population. Logistic regression models were constructed. Hispanic ethnicity was associated with physician-diagnosed MCS (adjusted odds ratio (OR) = 1.82, 95% confidence interval (CI) 1.21-2.73). Female gender was associated with individual self-reports of sensitivity (adjusted OR = 1.63, 95% CI 1.23-2.17). Marital status, employment, education, geographic location, and income were not predictive of reported chemical sensitivities or reported doctor diagnosis. Surprising numbers of people believed they were sensitive to chemicals and made sick by common chemical exposures. The homogeneity of responses across race-ethnicity, geography, education, and marital status is compatible with a physiologic response or with widespread societal apprehensions in regard to chemical exposure.
In this cross sectional descriptive study, the demographics, risk factors, and health outcomes of a volunteer, symptomatic sample of monolingual Cantonese garment workers in the Oakland, California Chinatown area are documented. Methods included a questionnaire and clinical examination and treatment at the Asian Immigrant Women Workers Clinic, a free clinic providing culturally focused occupational health consultation and treatment for painful musculoskeletal disorders. Because garment work involves highly repetitious, sustained awkward postures, focused education on stretching and ergonomics also was provided. Results from the first 100 clients revealed a highly symptomatic sample, with an average age of 48.7 years. Sixty-six percent rated their health status as fair or poor. Sixteen percent of the sample had nerve entrapments, and 99% had a
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
