High blood lead levels (BLL) in pregnancy are associated with poor pregnancy outcome and neuro-behavioral deficits in infants. We investigated the prevalence of high BLL in pregnant women and its impact on pregnancy outcome in Kuwait. Blood from 194 mother-infant pairs were analyzed for lead by Atomic Absorption Spectrophotometry. Data were collected on birth weight, crown-heel length, head circumference, APGAR score, gestational age, and placental weight. Results revealed that 28% of pregnant women and 58% of infants had BLL > 10 mu g/dL. Cord BLL was significantly higher than maternal BLL (10.92 vs. 5.77 mu g/dL, p <.001). Maternal BLL was not significantly associated with any of the outcome variables tested, whereas, cord BLL was a significant negative predictor of APGAR score only in boys. A significant proportion of pregnant women and their children in Kuwait have lead levels well above the safety limit, which is a matter of public health concern.
