Background: The goals of this study were to 1) assess the validity of the questionnaire currently used by several Head Starts in Maricopa County (Phoenix, Arizona) to screen for lead poisoning risk, 2) pilot the application of fingerstick lead testing at health fairs, 3) describe the population that receives lead testing at a major Head Start health fair in Maricopa County, and 4) describe the prevalence of lead poisoning in children screened at a large Head Start health fair.

Methods: Data were collected from convenience samples at two large Head Start health fairs, one in 2003 (n=606) and one in 2004 (n=190).

Results: The screening questionnaire performed poorly; over 30% of parents had "don't know" or blank responses to all six questions and the questionnaire did not identify children with high blood lead levels. When one fingerstick was used for both anemia and lead testing, 30% of results were inconclusive due to an insufficient quantity of blood. Only 2 children out of 796 (.003%) had high lead levels (Ан10 ug/dl). When a separate fingerstick was used, however, only 2% of tests had an insufficient quantity.

90% of children tested were low-income, 68% had a history of Medicaid coverage, and 62% were from Spanish-speaking homes. Among Medicaid-eligible children, only 16 percent had been tested previously.

Conclusions: Fingerstick is a feasible method of blood lead testing, provided a fingerstick is done solely for lead testing. The screening questionnaire did not provide useful information to target testing among Head Start enrollees.
