“…Only 4 farmers reported consistent use of gloves, and only 1 washed before eating, smoking, or drinking. In the interviews in this project, 35% of the farmers reported wearing gloves when using animal insecticides, and about half the farmers reported washing before smoking or entering the house (6). Two farmers did not follow the instructions on the container, and 1 reported that he ate, smoke, or drank in the pesticide area.…”

“…Exposure information has usually been obtained with questionnaires that seek information on the workplace and work practices, under the assumption that these data can be used as surrogates for exposure measurements. This report is part of a project designed to evaluate techniques for collecting exposure data in epidemiologic studies on farmers (1,(5)(6)(7), and it describes the results of an air and relationship between exposures and exposure determinants to assess if any of them can be used as predictors of exposure. Because little information has been reported on the pesticide practices of animal farmers, a brief questionnaire was also administered to the subjects.…”

“…In general, farmers provide reliable information and considerable detail regarding their pesticide application history. 19,[28][29][30] The AHS cohort consists of licensed pesticide applicators who are responsible for a thorough understanding of pesticide regulations and for the purchase and application of chemicals. 31 Recall of pesticide use by the AHS cohort has been shown to be consistent with the dates these pesticides came onto the market.…”

Metolachlor is one of the most widely used herbicides in the United States. We evaluated the incidence of cancer among pesticide applicators exposed to metolachlor in the Agricultural Health Study, a prospective cohort study of licensed pesticide applicators in Iowa and North Carolina. A total of 50,193 pesticide applicators were included. Detailed information on pesticide exposure and lifestyle factors was obtained from self-administered enrollment questionnaires completed between 1993 and 1997; average length of follow-up was 7.33 years. Two metolachlor exposure metrics were used : (i) lifetime days personally mixed or applied metolachlor and (ii) intensity-weighted lifetime days (lifetime days 3 an intensity level). Poisson regression analysis was used to estimate relative risks (RR) and 95% confidence intervals (95%CI) for cancer subtypes by tertiles of metolachlor exposure. No clear risk for any cancer subtype was found for exposure to metolachlor. A significantly decreased RR was found for prostate cancer in the highest category of lifetime days exposure (RR 5 0.59; 95%CI, 0.39-0.89) and in the second highest category of intensity-weighted lifetime days exposure (RR 5 0.66; 95%CI, 0.45-0.97); however, the test for trend was not significant for either exposure metric. A nonsignificantly increased risk was found for lung cancer with lifetime days exposure in the highest category (RR 5 2.37; 95%CI, 0.97-5.82, p-trend 5 0.03) but not with intensity-weighted lifetime days. Given the widespread use of metolachlor and the frequent detection of metolachlor in both surface and ground water, future analyses of the AHS will allow further examination of long-term health effects, including lung cancer and the less common cancers.

La validez de los indicadores de exposición es una condición necesaria en epidemiología si se han de obtener resultados válidos en la medición de los riesgos asociados con la exposición a agentes nocivos en el entorno laboral. Sin embargo, llevar a cabo la validación de estos indica Las matrices contienen datos agrupados y, por consiguiente, pueden llevar a errores a la hora de clasificar las exposiciones individuales e introducir sesgos en la estimación de los riesgos. La evaluación por expertos es probablemente el método con el índice de validez más alto, pero puede entrañar costos muy altos en el caso de estudios de cierta magnitud. Otra posibilidad con buenas perspectivas es la de utilizar un modelo formal para evaluar las exposiciones patentes y mejorarlo mediante la evaluación por expertos en situaciones en las cuales los resultados del modelo parezcan alejarse de la realidad.Exposición ocupacional, epidemiología/métodos, medición de riesgo, riesgos laborales. RESUMENLos métodos que permiten determinar el historial de exposición individual están adquiriendo cada vez más importancia en la epidemiología ocupacional para la cuantificación fiable de asociaciones entre las exposiciones reales y los parámetros de salud y en-
