To determine the association between sarcopenia and incidence of UI in women aged 60 and older participating in the English Longitudinal Study of Ageing (ELSA).
An 8-year longitudinal study involving 1,575 women aged 60 and above enrolled in ELSA. Sarcopenia was defined following the criteria of the European Working Group on Sarcopenia in Older People (EWGSOP2) consensus, classifying participants as non-sarcopenic, probable sarcopenic, sarcopenic, and severely sarcopenic. UI was assessed using the question "During the past 12 months, have you had any uncontrolled loss of urine?" from the ELSA questionnaire. A multivariable Poisson regression model was employed to estimate the association between sarcopenia and the incidence of UI.
The risk of UI was significantly higher in sarcopenic and severely sarcopenic women compared to non-sarcopenic ones (IRR 1.44; 95% CI: 1.01 – 2.05), (IRR 1.45; 95% CI: 1.03 – 2.05), respectively. The association was not found for probable sarcopenic women (IRR 1.10; 95% CI: 0.89 – 1.34).
Both sarcopenia and severe sarcopenia increase the risk of UI in women aged 60 and older. Therefore, it is essential to implement preventive measures and clinical actions to mitigate this risk. Future randomized clinical trials could be conducted to evaluate the effect of reducing sarcopenia on the incidence of urinary incontinence in women over 60 years old.
This study provides evidence of the association between sarcopenia and an increased risk of UI after 8 years of follow-up in women over 60 years old. Interventions aimed at preventing and treating sarcopenia could be a key strategy to reduce the incidence of UI and improve the quality of life of older women.
