Risk Factors for Proximal Humerus Fracture

摘要: This case-control study of proximal humerus fracture included 448 incident female and male cases 2,023 controls aged 45 years or older identified in five Northern California Kaiser Permanente Medical Centers 1996-2001. Data were collected by using an interviewer-administered questionnaire. Some factors related to low bone mass, including number fractures since age dietary calcium intake, associated with increased risks fracture, thought protect against loss, such as menopausal hormone therapy carbonate tablet use, reduced risks. Fall-related risk previous falls, diabetes mellitus, difficulty walking dim light. Possible fall-related suggested for the first time this seizure medication use (adjusted odds ratio (OR) = 2.80, 95% confidence interval (CI): 1.45, 5.42), depression (OR 1.34, CI: 0.98, 1.84), almost always a hearing aid 1.92, 1.12, 3.31 vs. never prescribed), left-handedness 2.36, 1.51, 3.68 right-handedness). Difficulty activities daily living lack physical activity tended be risk. Prevention falls among frail, osteoporotic persons would likely reduce frequency fracture.
