This review has also shown that contiguous cleanup of residences has a three-fold greater reduction of children's blood lead levels compared with cleaning only those homes where children currently reside by reducing exposures attributable to neighboring properties.
Among those women who consumed ≥ 50% of pills, calcium was associated on average with a 15% reduction in blood lead levels compared with those taking placebo (p < 0.001).
Previous reports suggest that subjects with clinical hemochromatosis have higher (Barton et al. 1994) or equivalent (Åkesson et al. 2000) blood lead levels compared with normal controls.
Although ALAD 1-2 and 2-2 genotypes were present in lesser numbers, it was evident that subjects with ALAD2 allele showed higher blood lead levels compared to ALAD1 allele.
Furthermore, carriers of both HFE and TF variant alleles had 50% higher blood lead levels compared with wild-type subjects in models comparing the joint effect of combined HFE + TF genotype on blood lead levels.
Because model 3 allows a distinct estimate at each blood lead level score, it is useful to compare it directly with model 1, which constrains the effect of a one-unit increase in blood lead level to be uniform across observed scores.
Compared with black children, white children are overrepresented in the lower blood lead level categories (blood lead level, 1 to 3) and underrepresented in the higher blood lead level categories (blood lead level, 4 to ≥ 10).
A concurrent venous blood lead level defined lead exposure.
Age-adjusted data from the second National Health and Nutrition Examination Survey (NHANES II, 1976 1980; Silbergeld et al. 1988), the Hispanics HANES (HHANES, 1982 1984; Symanski and Hertz-Picciotto 1995), and NHANES III (1988 1994; Nash et al. 1998) showed higher blood lead levels among postmenopausal women compared with premenopausal women.
To elucidate the effects of avgas on blood lead levels, we compared blood lead levels in children living near airports in six counties in North Carolina with those in children living farther away from airports but residing in the same counties.
We used residence-specific environmental lead measurements from three epidemiologic datasets as inputs for the IEUBK model to predict blood lead levels, and compared these predictions with blood lead levels of children living at these residences.
