In women, urinary MEHHP and ∑DEHP concentrations were associated with obesity [Q4 vs Q1; OR=1.72 (1.19, 2.49) and OR=1.52 (1.04, 2.21), respectively].In men, urinary MBP concentration was found to be significantly associated with obesity [Q4 vs Q1; OR=0.71 (0.50, 0.99)].Women ≥50 y showed positive associations between the MEHHP, MEOHP, ∑DEHP, and MBzP concentrations and obesity [Q4 vs Q1; OR=1.94 (1.28, 2.94), OR=1.88 (1.21, 2.94), OR=2.04 (1.31, 3.18), and Q3 vs Q1; OR=1.45 (1.02, 2.05)], respectively. This evidence concerns the gene MBP and obesity due to melanocortin 4 receptor deficiency.
