Table 2.

Negative binomial regression results for the association between childhood blood lead measures, adult arrests 2003–2013, and lifetime arrests.

Blood lead variable	Adult arrests	Violent arrests	Drug arrests	Property arrests	Lifetime arrests
IRR (95% C.I.)
Prenatal blood lead	1.15 (1.03–1.27)^a	1.17 (0.98–1.40)	1.21 (1.02–1.43)^a	0.96 (0.80–1.14)	1.16 (1.06–1.28)^a
Average childhood blood lead	1.03 (0.99–1.08)	1.01 (0.94–1.09)	1.06 (0.98–1.15)	1.03 (0.96–1.11)	1.02 (0.97–1.07)
Average late childhood blood lead	1.07 (1.01–1.13)^a	1.04 (0.96–1.14)	1.13 (1.03–1.24)^a	1.02 (0.93–1.12)	1.06 (1.00–1.13)^a
6-year blood lead	1.07 (1.00–1.14)	1.08 (0.96–1.21)	1.17 (1.02–1.33)^a	1.00 (0.89–1.12)	1.08 (1.01–1.16)^a

Coefficients significant at P < .05, two-tailed tests, Huber-White standard errors with age, race, sex, maternal IQ, birth weight (in grams), HOME 36 Month, Maternal age at delivery, APGAR 1-min, Maternal drug use during pregnancy, and WISC-R controlled in each equation.
