Aim: To examine the association between psychosocial exposures during pregnancy and the risk of infantile colic. Methods: The study included 378 infants and was conducted as a substudy of the Danish National Birth Cohort from 1997 to 1999, with prenatal data collected twice during pregnancy. A diary with a record for postpartum weeks 4–8 was used to quantify the amount of the infants' crying and fussing. Results: The cumulative incidence proportion of infantile colic was 8.2%. A threefold increased risk of infantile colic (OR = 3.7; 95% CI: 1.1–13.2) was found for mothers who reported distress during pregnancy. Close to a twofold increased risk of IC was found for the women who scored higher than 8 on the psychological distress scale (adjusted OR = 1.9; 95% CI: 0.5–7.2).

Conclusion: The results indicate that general distress during pregnancy influences the risk of infantile colic. Whether or not this relationship is causal requires further investigations.
