older adults, respiratory muscle strength, sarcopenia


Older people are at significantly increased risk of health problems including musculoskeletal and respiratory problems. Recently, sarcopenia, which is loss of muscle mass and physical performance, is associated with a reduction in activities in daily life and poor quality of life later.  In addition, poor respiratory performance leads to high risk of pulmonary complications in older adults such as dyspnea, pneumonia. Hence, the study aimed to explore the prevalence of sarcopenia and respiratory muscle strength in older people.
A survey preliminary study cross-sectional study was designed with 100 older people aged 65 years and over. All participants were diagnosed with sarcopenia in groups according to the Asian Working Group for Sarcopenia version 2019, consisting of handgrips strength, gait speed (6-meter walk test), and skeletal muscle mass (measured bioelectric impedance analysis). Maximum respiratory pressures were assessed. Descriptive analysis was used. To explore the difference in respiratory performance between sarcopenia and no sarcopenia, t-test and chi-square test was used; where appropriate. P-value was set at less than 0.05 and data was analyzed by SPSS program version 23.0.  The results found that the prevalence of sarcopenia was 32 (76.84±7.33 years).  Older adults were identified as having sarcopenia had advanced aged (76.84 ± 7.33 vs 71.15 ± 5.82 years, p<0.001), slow gait speed (0.82 ± 0.19 vs 1.05 ± 0.21 m/s, p<0.001), low skeletal muscle mass index (5.24 ± 0.90 vs 7.46 ± 2.16 kg/m2, p<0.001) and poor respiratory performance (i.e., weakness of inspiratory muscle strength 41.09 ± 23.08 vs 59.77 ± 24.07 cmH2O; p> .001). In this study, the prevalence of sarcopenia in older people aged 65 year was 32%.  In addition, older people with sarcopenia shown a reduction in inspiratory muscle strength compared to older people with no sarcopenia.
