AbstractLead is a heavy metal without a biological role. High level of lead exposure is known to be associated with hypertension, but the risk at low levels of exposure is uncertain. In this study, data from US NHANES 1999–2016 were analyzed. Adults with blood lead and blood pressure measurements, or self-reported hypertension diagnosis, were included. If not already diagnosed, hypertension was defined according to the AHA/ACC 2017 hypertension guideline. Results were analyzed using R statistics version 3.5.1 with sample weight adjustment. Logistic regression was used to study the association between blood lead level and hypertension. Odds ratio (OR) and 95% confidence interval (95% CI) were estimated. Altogether, 39,477 participants were included. Every doubling in blood lead level was associated with hypertension (OR [95%CI] 1.45 [1.40–1.50]), which remained significant after adjusting for demographics. Using quartile 1 as reference, higher blood lead levels were associated with increased adjusted odds of hypertension (Quartile 4 vs. Quartile 1: 1.22 [1.09–1.36]; Quartile 3 vs. Quartile 1: 1.15 [1.04–1.28]; Quartile 2 vs. Quartile 1: 1.14 [1.05–1.25]). In conclusion, blood lead level is associated with hypertension in the general population with blood lead levels below 5 µg/dL. Our findings suggest that reducing present levels of environmental lead exposure may bring cardiovascular benefits by reducing blood pressure.

Lead Levels

1 The effect on the blood lead levels of residents in an area in which a soft plumbo-solvent water was hardened is examined. 2 Water lead levels fell after hardening was introduced whereas there was a small rise in water lead levels in a control area monitored over the same time. 3 The blood lead levels of residents fell after hardening and the fall was slightly greater than would have been predicted on the basis of the change in water lead levels. This suggests that lead is less well absorbed from hard water than from soft water. 4 Following hardening there was a significant fall in mean blood lead level of subjects living in houses which had initially had negligible amounts of lead in the water. This suggests that hard water may interfere with the absorption of lead from sources other than water.

Long Term Follow Up

To the Editor.— In October 1991, the Centers for Disease Control decreased the blood lead level PbB) from 25 to 10 µg/dL and designated it as abnormal because of "overwhelming and compelling scientific evidence"1 that 10 µg/dL is associated with adverse neurobehavioral development. We have evidence to the contrary, obtained in a long-term follow-up of severely lead-poisoned children whom we treated before 1972 for PbBs between 80 and 470 µg/dL (mean, 150.3 ± 77.1 µg/dL); their mean age was 28 months.

Negative Effect

Background: We examined the effects of lead on kidney function in occupationally and environmentally exposed adults from a Dallas lead smelter community that was the site of an Environmental Protection Agency (EPA) Superfund clean-up. All subjects were African Americans—a racial group that bears a disproportionate burden of kidney disease. Methods: A two-phase health screening was conducted. Phase II included a physical examination and laboratory tests. Study subjects were African Americans residents, aged ≥19 years to ≤89 years. Of 778 subjects, 726 were environmentally exposed and 52 were both occupationally and environmentally exposed. The effects of lead exposure on estimated glomerular filtration rate (eGFR) were examined in three groups: male and female smelter-community residents, as well as males with both occupational and environmental exposure. Multiple linear regression was used to analyze the dependence of eGFR on log (blood lead level), duration of residence in the community, type 2 diabetes, and hypertension. Results: There was a statistically significant negative effect on kidney function for all three groups. Comparison of female and male residents showed a slightly larger negative effect of blood lead level on eGFR in females versus males, with the largest effect seen in male smelter-working residents. For each unit increase (log10 10µg/dL = 1) in blood lead level, age-adjusted eGFR was reduced 21.2 mL/min/1.73 m2 in male residents, 25.3 mL/min/1.73 m2 in female residents and 59.2 mL/min/1.73 m2 in male smelter-working residents. Conclusions: Chronic lead exposure is associated with worsening kidney function in both African American male and female residents, as well as male workers in Dallas smelter communities. This effect is slightly, but not statistically significantly, worse in female residents than male residents, and significantly worse in males that both worked and resided in the smelter community.

Elevated Blood Lead Levels

Objectives. In 1991, the Centers for Disease Control and Prevention (CDC) decreased the blood lead level of concern to 10 µg/dL (0.48 µmol/L) and recommended universal screening. Because these guidelines continue to provoke controversy, we conducted a study to:1) estimate the proportion of pediatricians who are members of the American Academy of Pediatrics (AAP) who report screening for elevated blood lead levels; 2) describe their clinical practices regarding screening for elevated blood lead levels; 3) compare attitudes of universal screeners, selective screeners, and nonscreeners; and 4) identify characteristics of pediatricians who universally screen. Design. Confidential, cross-sectional survey of a nationally representative random sample of 1610 pediatricians conducted through the AAP Periodic Survey. Subjects. The study included 1035 responders (64% response rate). Analysis was limited to the 734 pediatricians who provide well-child care (ie, primary-care pediatricians). Results. Fifty-three percent of pediatricians reported screening all their patients aged 9 to 36 months, 39% reported screening some, and 8% reported screening none. Among those who screen, 96% use a blood lead assay. The primary risk factors for which selective screeners screen are: history of pica (94%); living in an older home with recent renovations (92%); living in an older home with peeling paint (93%); and having a sibling who had an elevated blood lead level (88%). Among primary-care pediatricians, 73% agree that blood lead levels ≥10 µg/dL should be considered elevated, and 16% disagree. However, 89% of primary-care pediatricians believe that epidemiologic studies should be performed to determine which communities have high proportions of children with elevated blood lead levels, and 34% of primary-care pediatricians believe that the costs of screening exceed the benefits. Conclusions. Three years after the Centers for Disease Control and Prevention issued new guidelines for the management of elevated blood lead levels, a slight majority of primary-care pediatricians in the United States who are members of the AAP report that they universally screen their appropriately aged patients, while most of the remaining pediatricians report screening high-risk patients. Many pediatricians may want additional guidance about circumstances under which selective screening should be considered.
