- Women who consumed probiotic milk have a lower risk for preeclampsia and preterm labor.
Why this matters
- Probiotics may affect the inflammatory cascade that may lead to preterm delivery and preeclampsia.
- 23.3% of participants reported consumption of probiotic milk prior to pregnancy, 37.6% during early pregnancy, and 32.2% during late pregnancy.
- Preeclampsia was diagnosed in 5.0%.
- Intake of probiotic milk in late pregnancy was associated with a lower risk for preeclampsia (aOR, 0.80; 95% CI, 0.64-0.94).
- 5.2% had spontaneous preterm birth.
- Consumption of probiotic milk during early pregnancy was associated with a lower risk for preterm delivery (aOR, 0.79; 95% CI, 0.64-0.97).
- Cohort data from the Mother and Child Cohort Study, a prospective population-based pregnancy cohort study conducted by the Norwegian Institute of Public Health.
- Questionnaires were used to assess intake of milk products that contain probiotic lactobacilli.
- Main outcomes included preeclampsia (n=37,050 in preeclampsia analysis) and preterm delivery (n=34,458 in preterm labor analysis).
- Funding: None disclosed.
- Some women may have consumed probiotics from sources other than milk.
