• Description:
  Background:
  
  Previously we observed elevated odds ratios (ORs) for total pesticide exposure and ten birth defects: three congenital heart defects and structural defects affecting the gastrointestinal, genitourinary and musculoskeletal systems. This analysis examines association of those defects with exposure to seven commonly applied pesticide active ingredients.
  
  Methods:
  
  Cases were live-born singleton infants from the North Carolina Birth Defects Monitoring Program linked to birth records for 2003–2005; non-cases served as controls (total n=304,906). Pesticide active ingredient exposure was assigned using a previously constructed metric based on crops within 500 meters of residence, dates of pregnancy, and likely chemical application dates for each pesticide-crop combination. ORs (95% CI) were estimated with logistic regression for categories of exposure compared to unexposed. Models were adjusted for maternal race/ethnicity, age at delivery, education, marital status, and smoking status.
  
  Results:
  
  Associations varied by birth defect and pesticide combinations. For example, hypospadias was positively associated with exposures to 2,4-D (OR50-<90th percentile: 1.39 (1.18, 1.64)), mepiquat (OR50-<90th percentile: 1.10 (0.90, 1.34)), paraquat (OR50-<90th: 1.14 (0.93, 1.39)), and pendimethalin (OR50-<90th: 1.21 (1.01, 1.44)), but not S-metolachlor (OR50-<90th: 1.00 (0.81, 1.22)). Whereas atrial septal defects were positively associated with higher levels of exposure to glyphosate, cyhalothrin, S-metolachlor, mepiquat, and pendimethalin (ORs ranged from 1.22 to 1.35 for 50-<90th exposures, and 1.72 to 2.09 for >90th exposures); associations with paraquat were null or inconsistent (OR 50-<90th: 1.05 (0.87, 1.27).
  
  Conclusion:
  
  Our results suggest differing patterns of association for birth defects with residential exposure to seven pesticide active ingredients in North Carolina.
