Association of sarcopenia and frailty with sleep quality trajectories in middle-aged and older Chinese adults: findings from a nationally representative cohort study

Key Points

• Sarcopenia and frailty negatively impact sleep quality trajectories, highlighting a health concern.
• Key evidence includes negative associations observed in middle-aged and older Chinese adults throughout the study.
• Cohort study assessed the relationship between sarcopenia, frailty, and sleep quality in a nationally representative sample.
• Findings suggest addressing sarcopenia may mitigate sleep quality issues, with implications for older adult health strategies.
