Occupational Exposures and Cardiac Structure and Function: ECHO‐SOL (Echocardiographic Study of Latinos)

Background Our objective was to determine associations of occupational exposures with cardiac structure and function in Hispanic/Latino adults. Methods and Results Employed participants were included (n=782; 52% women, mean age 52.9 years). Occupational exposures to burning wood, vehicle exhaust, solvents, pesticides, and metals at the current and longest‐held job were assessed by questionnaire. Survey multivariable linear regression analyses were used to model the relationship of each self‐reported exposure with echocardiographic measures of cardiac structure and function. Exposure to burning wood at the current job was associated with decreased left ventricular (LV) ejection fraction (−3.1%; standard error [SE], 1.0 [P=0.002]). When the analysis was restricted to exposure at the longest‐held job, occupational exposure to burning wood was associated with increased LV diastolic volume (6.7 mL; SE, 1.6 [P
