Relationship Between Primary Language Spoken at Home and Blood Lead Levels in Children from Northeast Ohio, United...

Area of Science:

• Environmental Health
• Pediatric Health
• Epidemiology

Background:

• Elevated blood lead levels (BLLs) pose significant health risks to children.
• Understanding disparities in BLLs among different populations is crucial for targeted interventions.

Purpose of the Study:

• To estimate the prevalence and incidence of BLLs (≥5 and ≥3.5 µg/dL) in young children in Northeast Ohio.
• To assess the association between BLLs and primary language spoken at home, using it as a proxy for resettled refugee families (RRFs).

Main Methods:

• A retrospective cohort study of 19,753 children aged <6 years was conducted.
• Children were categorized as RRFs or non-RRFs based on primary language spoken at home.
• Prevalence and incidence rates of BLLs were calculated and compared between groups.

Main Results:

• Overall prevalence for BLLs ≥5 and ≥3.5 µg/dL were 3.22% and 6.10%, respectively.
• Incidence rates were 2.25 and 3.64 cases per 100 person-years for BLLs ≥5 and ≥3.5 µg/dL, respectively.
• Children from RRFs were 3.62 times more likely to have BLLs ≥5 µg/dL prevalence and 6.72 times more likely to have BLLs ≥5 µg/dL incidence compared to non-RRFs.

Conclusions:

• Children from RRFs exhibit significantly higher prevalence and incidence of elevated BLLs acquired in the U.S.
• These findings highlight a critical health disparity requiring further investigation.
• Identifying specific environmental and sociocultural lead exposure sources for RRFs children is warranted.
