Recent research from Flinders University has identified a potential biological marker in the throat microbiome that could shed light on the health vulnerabilities of older adults residing in long-term care facilities. The study suggests that certain bacterial populations in the oropharynx may be linked to increased health risks in this demographic.
Led by Ph.D. candidate Sophie Miller from the College of Medicine and Public Health, the research involved collecting oropharyngeal swabs from 190 residents across metropolitan South Australia. Over a 12-month period, the health outcomes of these individuals were monitored. The findings revealed a significant association between the presence of Staphylococcus aureus, a bacterium typically linked to infections, and higher mortality rates. Residents carrying this bacterium were found to be nearly ten times more likely to die within a year compared to non-carriers.
Miller notes that as individuals age, changes in the throat’s microbial community occur, influenced by factors such as polypharmacy and frequent healthcare interactions. These shifts may heighten susceptibility to diseases and frailty. The study advocates for incorporating throat microbiome analysis as a supplementary tool alongside traditional physical assessments, like grip strength measurements, to better identify and manage health risks in aged care populations.
This research aligns with broader studies highlighting the impact of the oral and throat microbiomes on overall health. For instance, a study published in Age and Ageing emphasized the role of oral microorganisms in conditions like aspiration pneumonia among older adults.Similarly, research from the University of Connecticut and Jackson Laboratory explored how changes in the skin, mouth, and gut microbiomes relate to aging and age-related health conditions.
Understanding the composition and changes of the throat microbiome in older adults offers promising avenues for early detection and intervention strategies, potentially improving health outcomes and quality of life for this population.
