Research Abstract

This study was conducted to assess the relationship between maternal blood lead concentrations and pregnancy-induced hypertension (PIH). Participants were 112 pregnant women, of whom 4 were PIH. There were no significant differences in blood lead concentrations between normal cases (1.23 ±1.4 μg/dl) and PIH cases (1.17±0.9μg/dl). The results of this study suggested that very low level lead exposure might not be a risk factor for PIH. Further studies with larger numbers of participants are needed to clarify the relationship between low blood lead levels and PIH among pregnant women in Tokyo.
