  • Objective Maternal smoking in pregnancy is a known risk factor for several birth defects, and long-term behavioral and cognitive problems in the offspring. Our objective was to investigate whether maternal smoking increases the risk for long-term gastrointestinal (GI) morbidity in the offspring.
