The Association Between Muscle Mass and Nutritional Risk by COAST in Older Adults

The association between muscle mass, as determined by BIA (bioelectric impedance analysis), and the recently developed COAST (Comprehensive Older Adult Screening Tool) has not been studied. Therefore, the main objective of this study is to test the correlations between muscle mass, measured by BIA, and COAST. The population to be studied will be older adults (n=150). Participants will be included if they are 60 years or older, willing to have weight, height, handgrip and body composition measured, willing to provided demographic information and answer questions related to their nutritional and health status. Individuals will be excluded if they have had recent surgery to the hands, severe rheumatoid arthritis in both hands or have a pacemaker or other implanted device. Participants will be recruited from community groups in Florida. Participants muscle mass will be measured using BIA. Also, their handgrip strength will be tested using a dynamometer. Weight and height will be measured and demographic information will be collected. In addition, the participants will be given COAST (5 questions related to their nutritional and health status). The associations among BIA, handgrip strength and the COAST will be analyzed.
