We conducted a questionnaire-based survey and gather blood and urine sample.Results By using robust regression model adjusted for age, sex, smoking, drinking and BMI, we find association of chromium in urinary with RBC (β=-0.09,P<0.01),MCH(β=1.71,P<0.01) and MCV(β=0.29,P<0.05)respectively. Furtheranalysis showed thatMCV’s relation with urinarychromium limited to individualsyounger than 60.Theassociation with RBC was only seen forwomen and the association with MCHC was only seen for men.
