A new paper published in the Journal of Occupational Health found that certain occupations in South Korea had a higher likelihood of miscarriage and stillbirth among pregnant women. The study analyzed data from 2010 to 2019 on more than 1.8 million employed and non-employed pregnant women and found that 18.0% of pregnancies ended in early abortive outcomes and stillbirths, while employed women had a higher risk of no live births.
According to a survey of more than 1.8 million employed and non-employed pregnant women in South Korea between 2010 and 2019, certain occupations were linked to a greater risk of miscarriage and stillbirth.
Investigators calculated risks for three undesirable outcomes, including early abortive outcomes (miscarriage, ectopic pregnancy, and molar pregnancy), and no live birth (pregnancy with no record of live birth thereafter, which include early abortive outcomes and stillbirth).
The risk of early abortive outcomes and stillbirths was greater in non-employed women than in employed women, while no live births were more frequent in employed women.
Women in the health and social work industries were at the most at risk of no live births. Higher risk of no live births were also observed in the manufacturing, wholesale/retail trade, education, and public/social/personal service occupations.
“Our research influenced the introduction of the occupational environment on adverse pregnancy outcomes,” said corresponding author Jung-won Yoon, MD of the National Medical Center in Seoul.
