Table 2 Relation between arsenic exposure and glucose tolerance status

From: Maternal arsenic exposure and gestational diabetes and glucose intolerance in the New Hampshire birth cohort study

   Glucose Intoleranta Gestational Diabetes Mellitusa Combined Glucose Intolerant and GDMb
Arsenic exposure Non-cases Cases OR (95 % CI) Cases OR (95 % CI) Cases OR (95 % CI)
Water As 663 79 1.0 (0.9, 1.1) 11 1.1 (1.0, 1.2)* 90 1.0 (0.9, 1.1)
Urinary As 582 61 1.0 (1.0, 1.1) 9 0.8 (0.3, 2.4) 70 1.0 (1.0, 1.1)

  1. aOutcome variable is a 3-level variable (0 = normal, 1 = intolerant, 2 = GDM), modeled using multinomial regression; bcombined glucose intolerance and GDM is modeled with logistic regression using a dichotomous variable (0 = normal or 1 = glucose intolerant and GDM). Models were adjusted for enrollment age, education, smoking during pregnancy, secondhand smoke exposure during pregnancy, pre-pregnancy BMI, weight gain and gestational week of glucose testing. Additional adjustment for urinary creatinine was included in the urinary As model only. Per 5 μg/L increase in water or urinary As; per 100 % increase in toenail As; *0.1 < p < 0.05; **p <0.05
