Table 3 Association of diabetesa with exposure to iAs in drinking water and iAs metabolites in urine, adjusted for age, sex, obesity and hypertension

From: Exposure to arsenic in drinking water is associated with increased prevalence of diabetes: a cross-sectional study in the Zimapán and Lagunera regions in Mexico

  1. Abbreviations: OR, odds ratio; CI, confidence interval.
  2. a Diabetes classified by either fasting blood glucose ≥126 mg/dL, 2-hour blood glucose ≥200 mg/dL, self-report of doctor diagnosis or use of anti-diabetic medication.
  3. b Units of OR and CI are 10 ppb for iAs concentration and ppm.years for cumulative iAs exposure. ORs for iAs metabolites are standardized to an increment of one inter-quartile range.
  4. c p-value for comparison of cases to individuals free of diabetes.
