GSTM1 and Zinc deficiency: Among women, non–daily alcohol consumption (OR = 1.62, 95% CI = 1.07‐2.46, P = .02), Hb (OR = 1.17, 95% CI = 1.00‐1.36, P = .04), Alb (OR = 14.96, 95% CI = 7.09‐31.57, P < .01), and TG (OR = 1.01, 95% CI = 1.00‐1.01, P = .02) were significantly associated with serum zinc deficiency/marginal deficiency.
