An exploratory analysis to determine priority areas for lead poisoning prevention education programs in Missouri.
Lead is a strong poison and toxic to many vital organs and body systems especially in the central nervous system of children, who are more vulnerable to lead poisoning than adults. The purpose of the study described in this article was to examine the relationship between elevated blood lead level (BLL) cases of children in the state of Missouri and pre-1980 home construction, lead mine proximity, and median household income and to determine counties and areas for statewide prevention education. Results of the regression analysis indicated that these combined variables were significant predictors (F[3,111] = 19.106, p < .05, R2 = .341), accounting for 34.1% of the explained variance in the number elevated BLL cases. Number of houses built prior to 1980 (β = .606, p < .05) and median household income (β = -0.186, p < .05) were specifically revealed to be significant predictors of elevated blood lead cases. In addition to screening in identified counties, Missouri's statewide plan should expand to include prevention education in all low-income counties.
