BACKGROUND: Arsenic exposure is associated with cardiovascular risk in adults; however, few epidemiologic studies have evaluated biomarkers of cardiovascular risk in children who are environmentally exposed to arsenic. OBJECTIVE: The aim of this study was to assess the associations between urinary arsenic, plasma natriuretic peptides and echocardiographic parameters in Mexican children exposed to arsenic through the drinking water. METHODS: We conducted a cross-sectional study with 192 children (3-8 years old) from Zimapan, Hidalgo, Mexico. B-type natriuretic peptide (BNP), NT-proBNP and atrial natriuretic peptide (ANP) were measured by ELISA, urinary arsenic concentration (UAs) were measured via by hydride generation-cryotrapping-atomic absorption spectrometry, and cardiac parameters were measured by echocardiography. RESULTS: The median plasma concentrations of ANP, BNP and NT-proBNP were 36.9 ng/mL, 49.7 pg/mL, and 226.1 pg/mL, respectively. Using multivariable models, a dose-response relationship was observed between BNP concentrations and UAs tertiles (<47 ng/mL: reference, 47-72 ng/mL: 48.7 pg/mL, >72 ng/mL: 52.2 pg/mL, P-trend = 0.020). BNP concentrations also increased with increasing U-tAs as continuous variables (0.43 pg/mL increase per 1 ng/mL increase of U-tAs; P-Value = 0.008). Additionally, BNP was positively associated with arsenic methylated metabolites (U-MAs and U-DMAs). On the other hand, BNP was inversely related to relative wall thickness (RWT). No associations were found for other cardiac parameters. Finally, neither ANP nor NT-proBNP were significantly related to arsenic exposure or echocardiographic parameters. CONCLUSIONS: In this study, we showed associations between plasma BNP and arsenic exposure. Our results support the importance of reducing childhood arsenic exposure, which may have cardiovascular effects early in life.
