Variation in Body Composition on the Fate of Older Subjects During SSR Hospitalization

Study Overview
=================
Brief Summary
-----------------
The aim of this study is to correlate weight variation as well as body composition with mortality and unscheduled readmission of geriatric population

Detailed Description
-----------------
Weight loss in obese adults confers health benefits, while weight loss in the elderly is associated with an increased risk of mortality. There are a large number of studies associating weight loss and mortality but the relationships between changes in body composition (ratio between fat mass and lean mass) and mortality are often contradictory and poorly understood in elderly subject. The aim at this study is to request at this question.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| The prognosis value of variation of weight on mortality | Determination of variation of weight between D0 and D21 after inclusion | 3 months | 
| Mortality rate | Monitoring of survival at 3 months after inclusion | 3 months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| The pprognosis value of variation of weight on unscheduled readmission in SSR | Determination of variation of weight between D0 and D21 after inclusion | Between D0 and D21 | 
| Unscheduled readmission in SSR | Monitoring of unscheduled readmission during 15 days after the end of hospitalization | during 15 days after the end of hospitalization | 
| Lean mass pronostic value | Determine the prognosis value of variation in lean mass on mortality and unscheduled readmission in SSR within 15 days of end of hospitalization | 3 months after the inclusion | 
| In fat mass pronostic value | Determine the prognosis value of variation in fat mass on mortality and unscheduled readmission in SSR within 15 days of end of hospitalization | 3 months after the inclusion | 
| fat / lean mass ratio | Determine the prognosis value of fat / lean mass ratio on mortality and unscheduled readmission in SSR within 15 days of end of hospitalization | 3 months after the inclusion |
