BMI Greater Than 30 Clinical Trial
Official title:
Establishment of a Database of Patients Suffering From Obesity With a Medical Treatment in the Framework of The Specialized Obesity Center Languedoc-Roussillon CHU Montpellier
Obesity is a public health problem, given its prevalence (15% in France in 2012, Obépi
survey) but also by the complications that it generates. We were firstly, intersted in bone
mineral density during obesity.
We were able to confirm in an observational study that BMD (Z-score)was augmented. We also
showed, for the first time, that this increase in Z-score was dependent on sex, severity of
obesity and age but also bone site. If the increase in BMD at the level of the bearing zones
seems logically to be explained by the hypothesis that the mechanical stresses have an
osteogenic effect on the bone tissue, the latter can not in any way respond to the
concomitant increase in BMD at non-bearing areas such as the radius.These results suggest
that changes in certain systemic compounds induced by obesity may interfere with bone
metabolism. recent data also suggest a change in the concentration of pro-glucagon peptides
(GLP-1, glicentin, glucagon, etc.) in obese subjects and in bariatric surgery). Although body
composition and its variation after surgery could be largely involved in the modification of
these peptides, no data on these potential relationships is currently available. However, no
data are available for baseline body composition and weight loss data. Finally, 80% of
obesity is associated with insulin resistance, a key mechanism in the pathophysiology of type
2 diabetes. A metabolically healthy obesity phenotype is described, although the definition
criteria are not consensual.The evolution of this phenotype with aging and with the duration
of evolution of obesity is not well described.
Our goal is to create a database of weight-bearing patients in the care setting and to
determine the "hormonal dialogue" between peripheral (muscular and adipose) and bone tissues,
which may be associated with changes in body composition during obesity and aging, and that
according to sex.
