Abstract

This study aimed to explore healthy life expectancy and investigate its predictors in 82 patients with stable chronic obstructive pulmonary disease (COPD). Furthermore, cut-off values for the identified predictors were established, and healthy life expectancy was compared between patients who exceeded these cut-off values and those who did not. Knee extension strength and Hospital Anxiety and Depression Scale (HADS) depression scores were significant independent predictors of healthy life expectancy. Moreover, individuals with poor lower knee strength or high HADS depression scores had more than twice the risk of a reduced healthy life expectancy than those with better scores. These findings suggest that focusing on improving lower muscle strength and managing depression is important for extending healthy life expectancy.
