*P for trend ≤0.05. a) Unadjusted; b) Adjusted for age, gender, race, and income; c) Adjusted for age, gender, race, income, smoking, iron, calcium, and Vitamin C; d) Adjusted for age, gender, income, and smoking; e) Adjusted for age, gender, income, smoking, and fruit and vegetable consumption. Data from NHANES 2001–2004, n = 18,626. Percentages are adjusted using survey weights to be representative of the United States population. Bold text indicates that the 95% CI does not cross 1.00, and the finding is considered significant. Abbreviations: MRSA – Methicillin-resistant Staphylococcus aureus; Q – Quartile; OR – Odds ratio; CI – Confidence interval; Pb – Lead; Cd – Cadmium
