The oral microbiome has been linked to various age-related health conditions such as rheumatoid arthritis and colorectal cancer. However, its potential association with sarcopenia is unknown.

In phase 1, a cross-sectional analysis will be conducted on a cohort of 200 individuals aged 70 years or older to examine the relationship between salivary microbiome and sarcopenia status. Participants will be recruited in the three main places of living: general community, assisted living facilities and nursing homes. The salivary microbiome composition will be evaluated utilizing shotgun metagenomics sequencing, while sarcopenia status will be determined through muscle mass (determined by whole-body bioelectrical impedance analysis and calf circumference), muscle strength (grip strength and the 5-times-sit-to-stand test) and physical performance (usual walking speed). In addition to investigating the microbiome composition, the study aims to elucidate microbiome functions by exploring potential omic associations with sarcopenia. To achieve this, salivary proteomics, metabolomics and quorum sensing peptidomics will be performed. Covariates that will be measured include clinical variables (sociodemographic factors, health status, health-related behaviours, oral health and quality of life) as well as blood variables (immune profiling, hormones, kidney and liver function, electrolytes and haematocrit).

It is unclear whether different measures of muscle size, strength, physical performance, and fitness have similar associations with quality of life.</p><p><strong>Objective: </strong>To describe associations of sarcopenia metrics with quality of life outcomes.</p><p><strong>Participants: </strong>Community-dwelling adults aged 70+ years participating in the SOMMA (Study of Muscle, Mobility and Aging) study, (N=875 ((women: 519, men:356)), age, years 76.3±5.0).</p><p><strong>Design and settings: </strong>Two academic medical centers.</p><p><strong>Measurements: </strong>Measures included muscle size (MRI- muscle volume. D3Cr muscle mass); strength and power (grip strength, leg extension power and strength, stair climb); walking and physical performance (4m and 400m walk, SPPB (Short Physical Performance Battery), chair stand); fitness (VO2 peak); health related quality of life (EQ-5D); and anthropometrics (weight, height, and body mass index). Results were stratified by sex. Correlations, scatterplots and linear regression models described the association between various measures of sarcopenia and fitness with overall quality of life score (EQ5D VAS) as a continuous variable. We also quantified differences between sarcopenia and fitness measures by overall QOL (Quality of Life) as a categorical variable (low, medium, high) and by QOL subcomponents (pain and discomfort, problems with usual activities, mobility, anxiety and depression, and problems with self-care) using distributionally appropriate methods.</p><p><strong>Results: </strong>Walking tests and physical performance were most consistently (but modestly) associated with overall quality of life (r~0.2, p<.001) and its subcomponents. For both men and women, several sarcopenia and fitness measures were more strongly associated with pain and usual activity than other QOL components.</p><p><strong>Conclusions: </strong>Poor performance, lower fitness and lower strength are related to worse quality of life, particularly pain, in older adults. Future studies should quantify these relationships longitudinally.</p>","PeriodicalId":51629,"journal":{"name":"Journal of Frailty & Aging","volume":"13 4","pages":"384-390"},"PeriodicalIF":3.3,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142689644","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
