摘要：

Frailty and osteoporosis are known to exacerbate each other. However, limited research is available on the shared pathophysiological factors contributing to osteoporotic fractures and frailty. This study aims to identify common factors associated with both the current frailty and the occurrence of incident vertebral fractures. A total of 912 postmenopausal Japanese women, 63.9 +/- 10.0 yr of age (mean +/- SD), were included in this study. Each participant's baseline frailty status was assessed using a questionnaire about the following 5 items: fatigue, resistance, ambulation, inactivity, and weight loss. A score of 3 or above indicated the prevalence of frailty. The participants were then followed up for an average of 10.5 +/- 7.5 yr, during which 202 patients suffered incident vertebral fractures. The Cox proportional hazards model for incident vertebral fracture revealed that lumbar bone mineral density (hazard ratio [HR] 0.753, p<.001), adiponectin (HR 1.025, p=.021), log IL-6 (HR 1.227, p=.029), prevalent vertebral fracture (HR 2.124, p<.001), and frailty status (HR 1.355, p=.002) were independent predictors of incident vertebral fractures. The factors associated with frailty status at baseline were assessed using logistic regression analysis, revealing that adiponectin (odds ratio [OR] 1.063, p<.001), log IL-6 (OR 2.94, p<.001), and prevalent vertebral fractures (OR 2.816, p<.001) were significantly associated with current frailty. Biochemical factors such as IL-6 and adiponectin were commonly associated with vertebral fractures and frailty. Additionally, frailty status was identified as an independent risk factor for vertebral fractures, while prevalent vertebral fractures were significantly associated with frailty. These findings clearly indicate that frailty and osteoporotic fractures represent mutual risks for each other, with serum levels of adiponectin and IL-6 serving as common physiological backgrounds.
