摘要

Around 51 million children globally are exposed to elevated levels of arsenic in drinking water However;the extent to which exposure is related to deaths from cancer at a young age is unknown.We assembled a cohort of 58,406 children aged 5-18 years from Health and Demographic Surveillance System of icddrb in Bangladesh and followed during 2003-2015.The follow-up period was 543415 person-years.We observed a significant association between childhood cancer mortality and arsenic exposure in the highest exposure tertile (HR=2.70,95% CI= 1-25-5.83).Arsenic exposure was associated with substantial increased risk of deaths at young age from cancers where child (5-11 years) had a higher risk of death compared to adolescent (12-18 years).
