HgH (μg/g)
Adjusted R ²	0.699
Standardized β coefficient
Total seafood intake (g/1000 kcal)	0.040
Large tuna intake (g/1000 kcal)	0.088*
HgB (μg/L)	0.782***
CdB (μg/L)
Adjusted R ²	0.063
Standardized β coefficient
Secondhand smoke exposure (no, yes)	0.043
Cereals intake (g/1000 kcal)	0.040
Meat intake (g/1000 kcal)	−0.129^#
Total seafood intake (g/1000 kcal)	0.189**
Total seaweed intake (g/1000 kcal)	−0.101
CdU (μg/g cr)
Adjusted R ²	0.059

HgB, HgH, CdB, CdU were logarithmically transformed. Total seafood, large tuna, and kelp intake were logarithmically transformed. All analyses included age (month), sex, and BMI as confounders
