Maternal Residential Atrazine Exposure and Gastroschisis by Maternal Age
Maternal and Child Health Journal, 2012Previous literature has suggested a link between maternal exposure to atrazine (the most commonly used herbicide in the US) and risk for gastroschisis (a birth defect that involves incomplete closure of the abdominal wall). Our objective was to evaluate the relationship between maternal atrazine exposure and gastroschisis risk by maternal age.

Journal of Mental Science, 1951In recent years several writers have attempted to bring the known aetiological effect of maternal age in mongolism into direct relationship with its causation.

Late maternal age and postdate pregnancy
American Journal of Obstetrics and Gynecology, 1989Charts of 443 postdate pregnancies were reviewed to determine the effect of late maternal age on pregnancy outcome. There were significantly more low 1-minute Apgar scores, intrapartum decelerations, and cesarean sections in the group of women greater than 35 years old. Use of oxytocin percentages and the results were similar with regard to both groups.
