BACKGROUNDScreening is effective in reducing the incidence and mortality of colorectal cancer. Rates of colorectal cancer test use continue to be low.METHODSThe authors analyzed data from the National Health Interview Survey concerning the use of the home‐administered fecal occult blood test (FOBT) and sigmoidoscopy/colonoscopy/proctoscopy to estimate current rates of colorectal cancer test use and to identify factors associated with the use or nonuse of tests.RESULTSIn 2000, 17.1% of respondents reported undergoing a home FOBT within the past year, 33.9% reported undergoing an endoscopy within the previous 10 years, and 42.5% reported undergoing either test within the recommended time intervals. The use of colorectal cancer tests varied by gender, race, ethnicity, age, education, income, health care coverage, and having a usual source of care. Having seen a physician within the past year had the strongest association with test use. Lack of awareness and lack of physician recommendation were the most commonly reported barriers to undergoing such tests.CONCLUSIONSLess than half of the U.S. population age ≥ 50 years underwent colorectal cancer tests within the recommended time intervals. Educational initiatives for patients and providers regarding the importance of colorectal cancer screening, efforts to reduce disparities in test use, and ensuring that all persons have access to routine primary care may help increase screening rates.

Hispanics in the United States have a disproportionately high risk for non-insulin-dependent diabetes mellitus (type 2 diabetes) compared with non-Hispanic whites. Little is known of the attitudes and beliefs about diabetes in this group. Using data from six focus groups of 42 Mexican Americans (14 men and 28 women), we characterized perceptions about the causes of and treatments for type 2 diabetes. Many participants believed diabetes is caused by having a family history of the disease, eating a diet high in fat or sugar, and engaging in minimal exercise. Experiencing strong emotions such as fright (susto), intense anger (coraje), or sadness and depression (tristeza) was also thought to precipitate diabetes. Nearly all participants expressed the belief that it is important to follow doctors' recommendations for diet and exercise, oral medication or insulin; many also cited herbal therapies, such as prickly pear cactus (nopal) and aloe vera (savila) as effective treatments. These findings may be useful in designing interventions to reduce the burden of diabetes in Hispanic populations.
Objectives Residential proximity to pesticide-treated farmland is an important pesticide exposure pathway. Methods In-person interviews and biological samples were collected from 100 farmworker and 100 non-farmworker adults and children living in Eastern Washington State. We examined the relationship of residential proximity to farmland to urinary metabolite concentrations of dimethylphosphate (DMTP) and levels of pesticide residues in house dust. Results DMTP concentrations were higher in farmworkers than non-farmworkers (71 μg/L vs 6 μg/L) and in farmworker children than non-farmworker children (17 μg/L vs 8 μg/L). Compared to non-farmworker households, farmworker households had higher levels of azinphos-methyl (643 ng/g vs 121 ng/g) and phosmet (153 ng/g vs 50 ng/g). Overall, a 20% reduction in DMTP concentration was observed per mile increase in distance from farmland. Conclusions Lower OP metabolite concentrations correlated with increasing distance from farmland.
