CREAL: Employment during pregnancy is associated with fewer numbers of preterm births


News from CREAL


This study, published in Scandinavian Journal of Work Environmental Health and led by CREAL researchers, suggests that, overall, employment during pregnancy is associated with a reduction in the risk of preterm birth and that work in certain occupations may affect pregnancy outcomes. This study provides a good picture of the overall impact on the course of pregnancy in important occupational sectors of the women’s workforce in Europe.

“Among employees, we defined groups of occupations representing the main sectors of employment for women where potential reproductive hazards are considered to be present”, specifies Dr. Maribel Casas, researcher from CREAL, an ISGlobal allied center, and first author of this study.

The researchers assessed whether maternal employment during pregnancy – overall and in these selected occupational sectors – was associated with birth weight, small for gestational age, term low birth weight, length of gestation, and preterm delivery in a population-based birth cohort design. With this aim the scientists used data from more than 200.000 mother-child pairs enrolled in 13 European birth cohorts.
