Insights
Suburban children are at risk for lead exposure, with many showing elevated blood lead levels. Pediatricians should consider lead screening for young patients in nonurban family practice settings.
Area of Science:
- Environmental Health
- Pediatric Toxicology
- Public Health
Background:
- Lead exposure poses significant risks to children's behavioral and intellectual development.
- Recent research indicates lead toxicity in children at lower levels than previously assumed.
- Children in urban areas, particularly Black children, are identified as high-risk populations.
Purpose of the Study:
- To assess lead exposure risk among children attending a suburban family practice center.
- To determine the prevalence of elevated blood lead levels in this demographic.
Main Methods:
- Voluntary blood lead level screening was conducted on 1-year-old patients.
- Venous blood specimens were collected over a 7-month period from 40 children.
Main Results:
- 43% of children had blood lead levels between 0.0-0.2 mumol/L (0-4 µg/dL).
- 38% had levels from 0.24-0.43 mumol/L (5-9 µg/dL).
- 20% of children exceeded 0.48 mumol/L (10 µg/dL), with the highest at 0.82 mumol/L (17 µg/dL).
- 75% of children with elevated levels lived in suburban areas.
Conclusions:
- Children in suburban family practice settings are susceptible to lead exposure.
- Primary care physicians in nonurban areas should consider routine lead screening for pediatric patients.
Background:
The adverse effects of lead on behavioral and intellectual development have been recognized for many years. During the past 10 years several studies have shown that lead is toxic to children at levels previously thought to be harmless. Black children living in urban neighborhoods have been identified as being at greatest risk.
Methods:
To determine whether children seen in a suburban family practice center were being exposed to lead, voluntary screening of 1-year-old patients was performed.
Results:
Over a 7-month period venous specimens for blood lead level were obtained from 40 children. Seventeen (43%) of the children had levels of 0.0 to 0.2 mumol/L (0 to 4 micrograms/dL). Fifteen (38%) had levels of 0.24 to 0.43 mumol/L (5 to 9 micrograms/dL). Eight (20%) children had levels of 0.48 mumol/L (10 micrograms/dL) or greater. The highest value obtained was 0.82 mumol/L (17 micrograms/dL). Seventy-five percent of the children with significantly elevated lead levels resided in suburban communities.
Conclusions:
Children seen in a suburban family practice setting are at risk for lead exposure, and screening should be considered by primary care physicians who practice in nonurban settings.
