BackgroundLead effects on children and pregnant women are grave, and screening tests would be logical to detect high blood lead levels (BLLs) in early stages.Materials And MethodsBlood samples were taken from the pregnant mothers who referred to midwifery clinic with further phone interview postdelivery.ResultsIn 100 patients evaluated, the mean age was 29 ± 5 years (median interquartile range gestational age of 33 [24, 37] weeks). There was a significant correlation between polluted residential area and median BLL (P = 0.044) and substance exposure (P = 0.02). The median BLL was significantly lower in those without a history of lead toxicity in the family (P = 0.003). The only factor that could predict the BLL levels lower than 3.2 and 5 μg/dL was living in the nonindustrial area. All pregnant women delivered full-term live babies.ConclusionPositive history of lead toxicity in the family and living in polluted areas may pose a higher BLL in pregnant women.
