Abstract

Background: Few studies have examined the association between home use of solvents and

paint and the risk of childhood leukemia.

Objectives: In this case-control study, we examined whether the use of paint and petroleum

solvents at home before birth and in early childhood influenced the risk of leukemia in

children.

Methods: Our analyses were based on 550 cases of acute lymphoblastic leukemia (ALL), 100

cases of acute myeloid leukemia (AML), and 1 or 2 controls per case individually matched for

sex, age, Hispanic status, and race. Further analyses were conducted by cytogenetic

subtype. Conditional logistic regression techniques were used to adjust for income.

Results: ALL risk was significantly associated with paint exposure (odds ratio (OR)=1.65,

95% confidence interval (95% CI) 1.26-2.15) with a higher risk observed when paint was

used postnatally, by a person other than the mother, or frequently. The association was

restricted to leukemia with translocations between chromosomes 12 and 21 (OR=4.16, 95%

CI 1.66-10.4). No significant association was found between solvent use and ALL risk overall

(OR=1.15, 95% CI 0.87-1.51) or for various cytogenetic subtypes, but a significant

association was observed in the 2.0-5.9 age group (OR=1.55, 95% CI 1.07-2.25). In contrast,

a significant increased risk for AML was associated with solvent (OR=2.54, 95% CI 1.19-

5.42) but not with paint exposure (OR=0.64, 95% CI 0.32-1.25).

Conclusions: The association of ALL risk with paint exposure was strong, consistent with a

causal relationship, while further studies are needed to confirm the association of ALL and

AML risk with solvent exposure.
