Abstract

A history of fracture in adulthood and urinary pentosidine levels were independently and significantly associated with fracture occurrence in this prospective observational study of community-dwelling older adults.

Purpose: This prospective observational study aimed to determine the factors associated with fragility fractures in community-dwelling older adults.

Methods: Overall, 254 older adults who were participants of the Good Aging and Intervention Against Nursing Care and Activity Decline study in 2016 were included in this study. Grip strength, muscle mass, gait speed, calcaneal bone density, and the levels of parathyroid hormone, osteocalcin, 25-hydroxyvitamin D, total procollagen type I N-terminal propeptide, insulin-like growth factor-1 (IGF-1), tartrate-resistant acid phosphatase-5b, and urinary pentosidine were measured at baseline. Participants were classified as fracture ( +) or fracture (-) based on the data collected during a 5-year follow-up period.

Results: Excluding those who were lost to follow-up during the observation period, 182 participants (64 men and 118 women, mean age: 74.2 years, range: 47-99 years) were included in the analysis. During the observation period, 23 patients experienced 24 new fractures. In univariate analysis, sex, height, weight, history of fracture in adulthood, baseline grip strength, muscle mass, bone density, and the levels of urinary pentosidine and IGF-1 at baseline were significantly different between patients who developed a fracture during follow-up and those who did not. In multivariate analysis, a history of fracture in adulthood and urinary pentosidine levels were independently and significantly associated with fracture occurrence.

Conclusion: High urine pentosidine levels and a history of fracture in adulthood are independent risk factors for fracture occurrence in community-dwelling older adults.
