Abstract(s)

Introduction: Aging is an inevitable, complex and multifactorial process that leads to a set of physiological, biochemical and biomechanical changes. The present study aims to evaluate the relationship between peripheral oxygen saturation values, functional mobility, physical activity levels and quality of life in elderly people. Materials and methods: Cross-sectional study, with a sample (n=48) of elderly people. Characterisation data, oxygen saturation values, functional mobility, physical activity levels, and quality of life were collected. Results: There were statistically significant differences (p≤0.05) between the SpO2 values of subjects aged 65-79 years (96.3±1.8%) versus those aged ≥80 years (94.6±2.7%); and be-tween those who reported mobility problems (94.6±2.6) and those who did not (96.5±1.6). We also observed a moderate positive correlation (r=0.437) between SpO2 values and the mean number of steps recorded during 4 days and a moderate negative correlation (r=-487) with the times recorded in TUG. No statistically significant correlations were found between QoL and SpO2 levels. Conclusions: A decrease in SpO2 values was observed with age progression, and subjects with lower values had worse functional mobility and lowered physical activity levels. QoL is influenced by a wide range of internal and external conditions may explain the lack of signifi-cant correlations with SpO2. Even so, of the four QoL domains analysed, the physical domain showed the highest correlation coefficient.
