Abstract
Context: Although long-term glucose variability has been reported to be a risk factor associated with osteoporosis, there have been no previous studies between the relationship of glucose variability and fractures in people without diabetes. Objective: We assessed visit-to-visit variations in fasting plasma glucose (FPG) as a prognostic factor in predicting osteoporotic fractures in individuals without diabetes. Methods: Using a nationwide cohort database, we examined the impact of FPG on the development of osteoporotic fractures in men and women (aged ≥50 years). The primary outcomes were the number of total fractures and vertebral fractures. FPG variability was measured using standard deviation (FPG-SD), coefficient of variation (FPG-CV), and variability independent of the mean (FPG-VIM). Results: Of the 92 929 participants, 5262 (5.7%) developed osteoporotic fractures during the mean follow-up of 8.4 years. Individuals in the highest quartile of FPG-SD showed an 11% and 16% increase in risk of total and vertebral fractures, respectively, compared with those in the lowest quartile after adjustment for mean FPG and other risk factors. Analyses using FPG-CV and FPG-VIM demonstrated similar results. Subgroup analyses and sensitivity analyses to explore potential heterogeneity showed consistent results. Conclusion: FPG variability may be a novel risk factor for osteoporotic fractures independent of risk factors in the general population without diabetes.
