Low to moderate toenail arsenic levels in young adulthood and incidence of diabetes later in life: findings from the CARDIA Trace Element study

Some studies suggest a positive association between arsenic exposure and risk of diabetes. However, the findings are inconsistent and inconclusive, particularly at a low to moderate arsenic exposure level, and longitudinal data are lacking. We examined toenail arsenic at low to moderate level in young adulthood in relation to incidence of diabetes later in life. This study included 4102 black and white participants aged 20-32 at baseline...
