Abstract: Objective To identify the risk factors for osteoporosis in patients with hemiplegia. Methods The total body bone mineral density (BMD) of 366 patients with hemiplegia in the stage of rehabilitation was measured with dual-energy X-ray absorptiometry. The data of the patients were analyzed with multiple logistic regressions. Results The incidence of osteoporosis was 15.3 % (56/366) in the cohort. ≥60 years old (OR=5.434, 95% CI:2.734～10.801), duration of disease (OR=1.046, 95% CI:1.013～1.080), body mass index (BMI) (OR=0.746,95% CI:0.622～0.840),ADL level (OR=0.618, 95% CI: 0.444～0.858) were independently correlated with osteoporosis in patients with hemiplegia. Conclusion Patients with hemiplegia in the stage of rehabilitation were at a high risk of osteoporosis. Aged over 60 years old, lower BMI, longer duration of disease and ADL level were independent risk factors for osteoporosis, which called for supervision and prophylaxis on osteoporosis.
