||Effects of maternal work activity during pregnancy on infant malformations
||Sep. 1998, Vol.40, No.9, p.829-834. 23 ref.
||The association between two birth defects, neural tube defects and oral cleft defects, and maternal physical work demands during the periconceptional period was examined. Occupational exposure information was collected from mothers of malformed infants and from those of non-malformed infants. Case groups were further subdivided on whether infants had additional defects. Results showed no general differences between cases and controls in most variables. However, those infants with cleft defects plus additional defects tended to have marginally increased risk in relation to maternal jobs requiring standing. Topics: case-control study; embryotoxic effects; expectant mothers; exposure evaluation; physical workload; questionnaire survey; standing posture; teratogenic effects.
