Relationship of Blood Pressure to Blood Lead Concentrations in Small Children
Elevated blood lead concentrations are associated with a variety of pathophysiologic changes in both children and adults, even in the absence of clinical symptoms. Although hypertension has been described in adults with elevated blood lead concentrations,1 there have been no systematic studies in infants and children in which lead levels were correlated with blood pressure measurements. In the present study, blood lead concentrations of greater than 40 µg/dl were associated with blood pressure elevations in infants and young children. SUBJECTS AND METHODS Thirty-four patients, age 1 to 3 years, who were referred to the Special Lead Clinic of the Jewish Hospital and Medical Center of Brooklyn because of blood lead levels of more than 40 µg/dl were subjects of the study.
