Remediating Soil Lead with Fish Bones

In a prospective study of more than 175,000 U.S. women, those who worked a rotating schedule that included 3 or more night shifts per month had a higher risk of developing type 2 diabetes than women who worked only days or only nights. 1 Women who worked rotating shifts were also more likely than other women to become obese during the 18-20 years of followup. The results suggest the increased risk of diabetes may be at least partly mediated through weight gain.
