The IR patients from groups [I+II] (12% of these groups) showed higher BMI, fat mass (FM) and visceral fat when compared with the non‐IR patients. In contrast, the IR patients from group III had mean BMI and total FM similar to those of non‐IR patients but showed a reduction of lean body mass and an increase in the relative proportion of trunk FM similar to the IR patients from groups [I + II]. This was associated with an altered lipid profile, high TNF‐α and IL‐6 levels, and reduced adiponectin levels compared to IR patients from group [I + II] and non‐IR patients.</p> </sec> <sec id="cen12047-sec-0005" sec-type="section"> <title>Conclusion</title> <p>Childhood ALL/NHL survivors treated by BMT/TBI frequently develop severe insulin resistance associated with peripheral‐to‐central fat redistribution, rather than increased total FM, and low adiponectin levels which may contribute to their increased CV risk.</p> </sec> </abstract>
