Loneliness showed a borderline significant association with sarcopenia after adjustment (OR: 1.52, 95% CI: 1.00–2.31, P = 0.049), indicating that sarcopenic individuals had about 50% higher odds of experiencing loneliness compared to their nonsarcopenic counterparts.
Associations with anxiety (OR: 1.49, 95% CI: 0.93–2.38, P = 0.095) and loneliness (OR: 1.52, 95% CI: 1.00–2.31, P = 0.049) were observed but did not reach statistical significance.
The data show a clear trend of increasing sarcopenia prevalence with age, particularly among women.
These calculations suggest that our study may have been underpowered to detect smaller effect sizes for anxiety and loneliness, which could explain the borderline significance of these associations.
