Objective: To evaluate the prevalence of multimorbidity and the association between multimorbidity and frailty in older adults with osteoporosis.
Method: A cross-sectional descriptive study was conducted on 296 older adults treated at the Department of Rheumatology, the Department of Neurosurgery, Rheumatology clinic, University Medical Center Ho Chi Minh city.
Results: The prevalence of multimorbidity among participants was 43,2% (128/296). The common comorbidities included osteoarthritis and hypertension. The multimorbidity group was more likely to have higher mean age, history of vertebral fracture, ADL and IADL dependence, and frailty than the non-multimorbidity group. However, the multimorbidity group was less likely to be physically active than the other group. In the univariate logistic regression model, multimorbidity was associated with frailty, but the association was insignificant when the regression models were adjusted for age.
Conclusion: Older adults with osteoporosis had a relatively high multimorbidity burden of 43,2%. Multimorbidity was associated with frailty in the univariate model but this association did not persist when the models were adjusted for age.
