Popis: Objectives To examine the relationship between occupation and blood lead levels in pregnant women of Durango, Mexico. Method A cross sectional study was conducted with 299 pregnant women. Information on occupation, risk factors and sociodemographic data was collected by means of a structured questionnaire. Blood lead concentration was tested by graphite furnace spectrometry. Women were divided into three groups according to occupation: working in places with potential source of lead exposure (exposed group), working in places without lead exposure (control group I), and non-working women (control group II). The X 2 test was used to assess statistical differences between the groups, and one way ANOVA was applied for comparisons. Logistic regression was performed using blood lead Results Only 24(8%) women worked in places with potential source of lead exposure, 47(15.7%) worked in other places, and 228(76.3%) did not have a remunerated job. Mean blood lead concentration in the study sample was 2.79 µg/dL. However, blood lead ≥ 5 µg/dL accounted for 25% of exposed women, 2.1% of control group I, and 6% of control group II (X 2 = 13.04; p .001). Mean blood lead level was 4.24 µg/dL in the exposed group, 2.31 µg/dL in the control group I, and 2.74 µg/dL in the control group II; those differences were statistically significant (0.001). Logistic regression confirmed that blood lead ≥ 5 µg/dL is associated with occupational exposure (p = 0.036). Conclusions Our findings suggest that surveillance for occupational exposure to prevent health damages during pregnancy is needed.
