SArcopenia Prevalence in Frail Older Adults. SAF Study

Not Applicable

Completed

• Conditions: Aging

• Registration Number: NCT02903992
• Lead Sponsor: University Hospital, Toulouse

Brief Summary

The age-associated loss of lean mass is a defining parameter of sarcopenia and may lead to various negative health outcomes such as impairment of physical performance and disability. Furthermore sarcopenia is considered to be one of the main factors in the pathogenesis of the frailty syndrome. However, for clinical use and for treatment and prevention strategies, reliable diagnostic criteria and cutpoints based on clinically relevant thresholds are indispensable.

This topic has recently been addressed by the Foundation for the National Institutes of Health Sarcopenia Project which identified cutpoints for appendicular lean mass (ALM) below which older adults had a higher likelihood of clinically relevant weakness reflected by low grip strength. Moreover, a low ALM-to-body mass index (BMI) ratio (\<0.789 men and \<0.512 women) was found to be associated with increased likelihood for mobility impairment.

In this context, the aim of this study is to study the prevalence of sarcopenia in a sample of community-dwelling frail and pre-frail older adults.

Primary Outcome Measures

Name	Time	Method
Sarcopenia Diagnostic with Dual-energy X-ray absorptiometry	one day (participation of subject)	The primary outcome of SAF study is to assess the prevalence of sarcopenia in frail and pre-frail older adults. The primary endpoint is the sarcopenia diagnostic. In patients with at least one Fried criteria, we would like to detect the number of patient with low lean muscle mass adjusted for body mass index \<0.789 for men and \<0.512 for women.

Secondary Outcome Measures

Name	Time	Method
(SPPB) score	one day (participation of subject)	Short Physical Performance Battery (SPPB) score
(IADL) score	one day (participation of subject)	Instrumental Activities of Daily Living (IADL) score
(MMSE) score	one day (participation of subject)	Mini-Mental State Examination (MMSE) score
(MNA) score	one day (participation of subject)	Mini Nutritional Assessment (MNA) score
