Obese Girls With Greater Ratio of Visceral Fat Have Lower Bone Density CHEVY CHASE, Md -- March 3, 2010 -- According to a study appearing in an upcoming issue of the Journal of Clinical Endocrinology & Metabolism, obese teenage girls with a greater ratio of visceral fat to subcutaneous fat are likely to have lower bone density than peers with a lower ratio of visceral to subcutaneous fat. “Visceral fat is known to increase the risk of diabetes and heart disease in obese people,” said senior author Madhusmita Misra, MD, Massachusetts General Hospital, Boston, Massachusetts. “Our study suggests that visceral fat may also have an impact on bone health. This finding is particularly relevant given the rising prevalence of obesity and recent studies suggesting a higher risk of fractures in some obese individuals.” In the study, Dr. Misra and colleagues examined 30 adolescent girls (15 obese/15 normal weight) between the ages of 12 and 18 years. After measuring weight and height, researchers used magnetic resonance imaging (MRI) to measure subcutaneous and visceral fat tissue and dual energy x-ray absorptiometry (DXA) to assess bone density at the spine, hip and whole body. They found that subcutaneous fat and visceral fat had reciprocal associations with bone density measures, with subcutaneous fat demonstrating positive associations and visceral fat demonstrating inverse associations. “We do not yet fully understand the chemical mediators of the associations between regional fat and bone health,” said Dr. Misra. “It is possible that inflammatory cytokines, types of signaling molecules used in cellular communication, or hormones like adiponectin or leptin are potential mediators of these associations between fat and bone, but further studies are needed to determine their true impact on bone metabolism.” SOURCE: The Endocrine Society E-mail this page to a friend or colleague!
