Adenocarcinoma of the stomach and esophagus and drinking water and dietary sources of nitrate and nitrite.

We conducted a population-based case-control study of adenocarcinoma of the stomach and esophagus in Nebraska, U.S.A.

Gliomas and farm pesticide exposure in men: the upper midwest health study.

The National Institute for Occupational Safety and Health evaluated farm pesticide exposure and glioma risk in a study that included 457 glioma cases and 648 population-based controls, all adult men (18-80 yr old) and nonmetropolitan residents of Iowa, Michigan, Minnesota, and Wisconsin. Multiple logistic regressions were used to control for farm residence, age, age group, education, and exposure to other pesticides. No associations were found between glioma and 12 specific pesticides.

Drinking water and dietary sources of nitrate and nitrite and risk of glioma.

Objective: Dietary nitrite has been associated with increased glioma risk; however, drinking water nitrate has not been extensively evaluated.

Methods: We conducted a population-based case-control study of adult glioma in Nebraska. Water utility nitrate measurements were linked to residential water source histories.

Hair dyes and risk of glioma among Nebraska women.

The etiology of brain cancer is not well understood. We conducted a population-based case-control study among 112 white women in Nebraska who were newly diagnosed with glioma between July 1988 and June 1993, and 215 controls, to identify risk factors for this disease. A 1.

Gliomas and farm pesticide exposure in women: the Upper Midwest Health Study.

An excess incidence of brain cancer in male farmers has been noted in several studies, but few studies have focused on women. The National Institute for Occupational Safety and Health Upper Midwest Health Study evaluated effects of rural exposures for 341 female glioma cases and 528 controls, all adult (18-80 years of age) nonmetropolitan residents of Iowa, Michigan, Minnesota, and Wisconsin. On average, controls lived longer on farms than did cases.

Reproductive factors and risk of glioma in women.

Objective: Glioma is the most common primary malignant brain tumor in adults, responsible for 75% of adult primary malignant brain tumors, yet aside from its association with ionizing radiation, its etiology is poorly understood. Sex differences in brain tumor incidence suggest that hormonal factors may play a role in the etiology of these tumors, but few studies have examined this association in detail. The objective of this study was to explore the role of reproductive factors in the etiology of glioma in women.

Application of a method to evaluate the quality of work histories and document the exposure assessment process.

Background: Review of work history records by industrial hygienists is an important component of many occupational epidemiologic studies. A number of factors may influence the hygienist, such as the quality of the data and his or her previous experience. As part of a case-control study of mesothelioma, a system was developed to capture data on several factors that can be considered in a review of work history information.

An asbestos job exposure matrix to characterize fiber type, length, and relative exposure intensity.

The relationship between asbestos exposure and disease has been well documented, although questions persist as to variation in risk by the type and length of fiber. For a series of jobs with potential asbestos exposure, the primary fiber type (e.g.

Diet and risk of adult glioma in eastern Nebraska, United States.

Objective: To investigate potential associations between diet and adult glioma.

Methods: We conducted a population-based case-control study of adult glioma in eastern Nebraska. Nutrient and food group intakes were estimated for 236 glioma cases and 449 controls using information obtained from a food-frequency questionnaire.

Nutrient intakes and adenocarcinoma of the esophagus and distal stomach.

We studied the relationship between nutrient intakes and adenocarcinoma of the esophagus and distal stomach among 124 esophageal adenocarcinoma cases, 124 distal stomach cancer cases, and 449 controls in a population-based case-control study in eastern Nebraska. The residual method was used to adjust nutrient intake quartiles or tertiles for energy intake. We observed significant inverse associations with risk of esophageal adenocarcinoma for dietary intakes of total vitamin A [highest vs.

Dietary patterns and adenocarcinoma of the esophagus and distal stomach.

Background: Dietary pattern analysis is a unique approach to studying relations between diet and disease.

Objective: Our objective was to describe the dietary patterns of an eastern Nebraska population and investigate the associations between those dietary patterns and risks of adenocarcinoma of the esophagus and distal stomach.

Design: We recruited 124 subjects with esophageal adenocarcinoma, 124 subjects with distal stomach adenocarcinoma, and 449 control subjects in a population-based, case-control study.
