To ascertain blood lead levels in a sample of preschool children from Fremantle, Western Australia, and to correlate these with possible risk factors.
The study was a cross-sectional prevalence survey of 120 children from day-care centres and 44 hospital inpatients.
Blood lead and ferritin levels were determined and a risk factor questionnaire was completed by parents.
Of the 164 children 25.6% had lead levels above the NH & MRC goal (<10 mug/dL).
Nine of 133 (6.7%) had ferritin levels below 10 mug/L suggesting iron deficiency.
Excessive blood lead concentrations as defined by the NH & MRC (>9mug/dL) related to : child's presence during house renovation (OR 3.35, P=0.007,95% Cl 1.39-8.81) ; Aboriginality (OR 6.4, P=0.008,95% Cl 1.6-24.9), and, in the 9-24 month age group, inversely to distance between home and a road carrying>7000 vehicles/day (r-0.56, P=0.009, n=24).
A group of Fremantle children with unacceptably high blood lead levels has been identified.
Renovation of older housing and Aboriginality are important risk factors.
