Blood Lead Levels in U.S. Children Ages 1-11 Years, 1976-2016.

ABSTRACT:

Background

Lead can adversely affect child health across a wide range of exposure levels. We describe the distribution of blood lead levels (BLLs) in U.S. children ages 1-11 y by selected sociodemographic and housing characteristics over a 40-y period.

Methods

Data from the National Health and Nutrition Examination Survey (NHANES) II (1976-1980), NHANES III (Phase 1: 1988-1991 and Phase II: 1991-1994), and Continuous NHANES (1999-2016) were used to describe the distribution of BLLs (in micrograms per deciliter; 1μg/dL=0.0483μmol/L) in U.S. children ages 1-11 y from 1976 to 2016. For all children with valid BLLs (n=27,122), geometric mean (GM) BLLs [95% confidence intervals (CI)] and estimated prevalence ≥5μg/dL (95% CI) were calculated overall and by selected characteristics
