BACKGROUND: Knowledge of the prevalence of work-related physical activities, @entity146 , and emotional stressors among pregnant @entity1 is limited, and the extent to which these exposures vary by maternal characteristics remains unclear. METHODS: Data on mothers of 6,817 @entity1 without major @entity600 , with estimated delivery during 1997 through 2009 who worked during pregnancy were obtained from the National @entity600 Prevention Study. Information on multiple domains of occupational exposures was gathered by linking mother's primary job to the Occupational Information Network Version 9.0. RESULTS: The most frequent estimated physical activity associated with jobs during pregnancy was standing. Of 6,337 mothers, 31.0% reported jobs associated with standing for >= 75% of their time. There was significant variability in estimated occupational exposures by maternal age, race/ethnicity, and educational level. CONCLUSIONS: Our findings augment existing literature on occupational physical activities, @entity146 , emotional stressors, and occupational health disparities during pregnancy. Am. J. Ind. Med. 59:137-149, 2016.    2015 Wiley Periodicals, Inc.
