Negative Binomial Regression Results of the Association Between Childhood Blood Lead Measures and Adult Arrests 2003–2013 with Controls for Prior Arrests from 1998 to 2003.

Blood lead variable	Adult arrests	Adult arrests	Adult arrests	Adult arrests
IRR (95% C.I.)
Prenatal blood lead	1.09 (0.99–1.20)
Baseline estimate	1.15 (1.03–1.27)^a
Average childhood Blood lead		1.05 (1.00–1.09)^a
Baseline estimate		1.03 (0.99–1.08)
Average late childhood blood lead			1.06 (1.01–1.12)^a
Baseline estimate			1.07 (1.01–1.13)^a
6-Year blood lead				1.04 (0.98–1.11)
Baseline estimate				1.07 (1.00–1.14)

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, WISC-R, and arrests from 1998 to 2003 controlled in each equation.
