文本框: THE MATERNAL AND UMBILICAL CORD BLOOD LEAD LEVELS IN HA-N AND UYGUR AND ANALYSIS OF ITS RELATIVE FACTORS Li M-X, Li W-CH First Affiliated Hospitol of XinJiang Medical University, Urumqi, China Objective: To estimste maternal and umbilical blood lead level in Han and Uygur in Urumqi area and its relative risk factors. Methods: Maternal and umbilical bloodlead level were determined in 139 cases of neonates (80 cases of Han and 59 cases of Uygur) between March and September, 2000. And surveyed environmental factors of the mothers and their families with a questionnaire. Results: (1) Among the 139 cases, maternal blood lead level were 10~267(84.91+47.46)μg/L, Umbilical blood lead level were 10~329 (65.08+43.88)μg/L. There was significant statistic correlation between blood lead level of pregnant women and their babies’s umbilical cords(r=0.7140, 0.7898, p<0.01). Maternal and umbilical blood lead level were higher in Uygur than that of Han (p<0.01, p<0.05). The blood lead lead level was ≥100μg/L in 54 cases of pregnant women and 49 cases of neonates. (2) The blood lead level of the neonates were associated with environmental factors (passive smoking of mother, environmental pollution, SES score of family, occupation of mother, cultural level of mo-ther, supplement of calcium during pregnancy). Conclusions: The maternal and umbilical blood lead level were significant different between Han and Uygur. It was correlated with environmental factors. Neonatal lead poisoning in Urumqi was relevant higher. Enough attention should be paid to the situation. 0812
