| Factor | Maternal overall exposure to chemicals at work |
| Description | Maternal overall exposure to chemicals at work during the first trimester was more prevalent among the case (n = 406) group ( 35 8 %) than among the control (n = 756) group ( 26 2 %, P < 0 01, X 2 -test). This was also true in most of the ontogenetic groups (VSD, CAS, LHHS, O) of congenital heart disease. |
| Biomarker | NA |
| Classification | B3 (environmental factor - exposure history) |
| Association | |
|---|---|
| Application | risk assessment |
| Objective | To investigate possible associations between cardiovascular malformations and maternal occupational exposure to various factors during the first trimester of pregnancy. |
| p Value | <0.05 |
| Conclusion | Maternal overall exposure to chemicals at work during the first trimester was more prevalent among the case (n = 406) group ( 35 8 %) than among the control (n = 756) group ( 26 2 %, P < 0 01, X 2 -test). This was also true in most of the ontogenetic groups (VSD, CAS, LHHS, O) of congenital heart disease. |
