Chronic arsenic exposure significantly increased percent body fat but not lean or fat body mass. A: fat and lean body mass; B: percent body fat; C: percent lean mass, determined via dual-energy X-ray absorptiometry (DEXA) and EchoMRI at study week 6. No significant differences observed comparing arsenic (n = 26; 13 arsenic vs. 13 controls). Data are represented in least squares means, with statistical significance determined by linear mixed models accounting for cohort as a random effect. **P < 0.01.
