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 [=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 [
