No study has been conducted to evaluate the association between avascular necrosis of the femoral head and diabetes. This study's aim was to assess this issue in Taiwan.
A population-based cohort study was performed to analyze the database of Taiwan's National Health Insurance Program. There were 27,869 subjects aged 20-84 years with newly diagnosed diabetes from 2000 to 2012 as the group with diabetes. The group without diabetes included 111,476 sex- and age-matched subjects without diabetes. The incidence of avascular necrosis of the femoral head at the end of 2013 was measured. A multivariable Cox proportional hazards regression model was used to measure the hazard ratio (HR) and 95% CI for avascular necrosis of the femoral head associated with diabetes.
The overall incidence of avascular necrosis of the femoral head was 1.37-fold higher in the group with diabetes than in the group without diabetes (6.53 vs. 4.76 per 1,000 person-years [95% CI 1.31-1.43]). After adjusting for confounders, the HR of avascular necrosis of the femoral head was 1.16 (95% CI 1.11-1.21) for the subjects with diabetes compared with the subjects without diabetes.
Patients with diabetes have a 1.16-fold increased risk for developing avascular necrosis of the femoral head.
目前尚无研究评估股骨头缺血性坏死与糖尿病之间的关系。本研究旨在评估台湾地区的这一问题。
本研究采用基于人群的队列研究，对台湾全民健康保险计划数据库进行了分析。共有 27869 例 20-84 岁新诊断为糖尿病的患者（2000 年至 2012 年）作为糖尿病组。无糖尿病组包括 111476 例年龄和性别相匹配的无糖尿病患者。于 2013 年底测量股骨头缺血性坏死的发生率。采用多变量 Cox 比例风险回归模型测量与糖尿病相关的股骨头缺血性坏死的风险比（HR）和 95%CI。
糖尿病组股骨头缺血性坏死的总发生率高于无糖尿病组（6.53 比 4.76/1000 人年[95%CI 1.31-1.43]）。调整混杂因素后，与无糖尿病组相比，糖尿病组股骨头缺血性坏死的 HR 为 1.16（95%CI 1.11-1.21）。
糖尿病患者发生股骨头缺血性坏死的风险增加 1.16 倍。
