ABSTRACT
PURPOSE: The Keokuk County Rural Health Study (KCRHS) is a longitudinal population-based study conducted in rural Iowa. A prior analysis of enrollment data identified an association of airflow obstruction with occupational exposures only among cigarette smokers. The current study used spirometry data from all three rounds to investigate whether level of forced expiratory volume in one second (FEV1) and longitudinal change in FEV1 were associated with occupational vapor-gas, dust, and fumes (VGDF) exposures, and whether these associations were modified by smoking. METHODS: This study sample comprised 1071 adult KCRHS participants with longitudinal data. A job-exposure matrix (JEM) was applied to participants' lifetime work histories to assign exposures to occupational VGDF. Mixed regression models of pre-bronchodilator FEV1 (millimeters, ml) were fit to test for associations with occupational exposures while adjusting for potential confounders. RESULTS: Mineral dust had the most consistent association with change in FEV1, including ever/never ( - 6.3 ml/year) and nearly every level of duration, intensity, and cumulative exposure. Because 92% of participants with mineral dust also had organic dust exposure, the results for mineral dust may be due to a combination of the two. An association of FEV1 level with fumes was observed for high intensity ( - 91.4 ml) among all participants, and limited to cigarette smokers with results of - 104.6 ml ever/never exposed, - 170.3 ml high duration, and - 172.4 ml high cumulative. CONCLUSION: The current findings suggest that mineral dust, possibly in combination with organic dust, and fumes exposure, especially among cigarette smokers, were risk factors for adverse FEV1 results.

RESUMEN Este trabajo refiere la trayectoria del Dr. Gregorio Miguel Delgado García, investigador incansable que ha dedicado la vida a la Historia de la Medicina, además de su ejemplo de consagración al trabajo y a la Revolución. El acercamiento a su trayectoria investigativa se realizó a través de una revisión documental de su expediente docente, búsqueda de información realizada en la base de datos Scielo, en el Google académico y Biblioteca Virtual de Salud sobre sus trabajos realizados y una entrevista efectuada por los autores, con la que se logró que narrara los momentos más importantes de una larga trayectoria llena de logros y vivencias inolvidables. Es por eso que el objetivo es divulgar los principales aspectos de la trayectoria profesional, docente y científica del historiador Dr. Gregorio Miguel Delgado García como reconocimiento a la obra de toda la vida.
ABSTRACT This paper presents the professional career of Dr. Gregorio Miguel Delgado García, a tireless researcher who has devoted all his life to the history of Medicine and whose dedication to work and the Revolution has been admirable. The approach to his research path was carried out through a document review of his teaching records, a search carried out in SciELO and Google Scholar databases, a review of all his works carried out in the Health Virtual Library and an interview made by the authors in which he recounted the most significant moments of his lifelong career that has been full of achievements and unforgettable memories. Therefore, this work aimed at spreading the main aspects of the professional, teaching and scientific career of the historian Dr. Gregorio Miguel Delgado García as a recognition of his lifetime work.
