Background: The aim of this study was to examine the association of shiftwork and pregnancy outcomes.
Methods: We conducted the survey with 1,000 Korean women workers who were selected by random sampling from ’Maternity Benefit Database’ and received a benefit from November 2001 through March 2003. The questionnaire contained experience of shiftwork and the pregnancy outcome such as spontaneous abortion, stillbirth, preterm birth and low-birth-weight.
Results: The percents of shift workers are 12.7. We found that shiftwork group had 1.92 times(95% CI=1.21～3.06) the odds of spontaneous abortion, 3.76 times(95% CI=1.40～9.07) the odds of preterm birth and 3.52 times(95% CI=1.84 ～6.76) the odds of low-birth-weight than non-shiftwork group.
Conclusions: This study suggested that spontaneous abortion, preterm birth and low birth weight in working women associated with shiftwork. Therefore the prevention program should be developed to preserve the female workers.
