Abstract
Childhood lead exposure remains a public health concern, as it can lower a child's intelligence quotient and cause permanent neurological damage. The objective of this study was to identify census tracts with the highest risk for blood lead levels (BLLs) >= 5 mu g/dL in Philadelphia, Pennsylvania. We analyzed BLLs among children born in 2008-2010 who had at least one venous BLL test. A multivariable mixed effects logistic regression model was used to create risk scores and estimate adjusted odds ratios (OR) for BLLs >= 5 mu g/dL and census tract-level characteristics, including median age of housing, percent of Black residents, vacant properties, rental properties, adults living in poverty, and adults with a high school education. Of 49,246 children, 14.37% had more than one BLL >= 5 mu g/dL. Census tracts with a higher percentage of pre-1950 housing (OR = 1.82, 95% confidence interval [CI] [1.63, 2.04]), Black residents (OR = 3.22, 95% CI [2.70, 3.84]), vacant properties (OR = 1.45, 95% CI [1.23, 1.72]), and poverty (OR = 1.49, 95% CI [1.18, 1.89]) were associated with the highest risk. The mean risk score was 0.12 (range: 0.02-0.35). Our findings show that risk scores can help target prevention activities.
