Hip fracture incidence rates in Hefei, China, over a period of 1 year (2010) were assessed. The aim of this study was to investigate the incidence and epidemiology of hip fracture in Hefei and compare it with other populations. All the hip fracture records were obtained from the Hefei Hospital Discharge Register for the entire population ≥50 years of age and restricted to cervical or trochanteric types. The incidence of hip fracture was standardized to the 2010 World population. A total of 1518 (aged ≥50) hip fractures (628 in men, 890 in women) were recorded during the study period. The age-adjusted incidence rate for 1 year was 144/100,000 (95 % CI = 135-153/100,000) for women and 97/100,000 (95 % CI = 85-109/100,000) for men. The standardized incidence rate against the 2010 World population was 151.7/100,000 for women and 98.2/100,000 for men. The mean age of patients with a hip fracture was 74.5 ± 10.1 years for women and 71.9 ± 11.9 years for men. The overall female to male ratio of hip fracture was 1.48:1 for hip fracture incidence and 1.54:1 for standardized incidence. Simple fall accounted for 85 % hip fractures in total cases. Hefei has a lower incidence of hip fracture compared with Beijing and other countries from the five continents in recent studies, but a higher incidence than those cities in north-east China in the early 1990s. The inequality incidence in different geographic areas could be due to the urbanization or life expectancy of the population, but further investigation needs to be done to confirm this hypothesis. We also found a higher incidence in women than in men. Simple fall may be the main mechanism of injury for hip fracture.
在中国合肥，对为期 1 年（2010 年）的髋部骨折发病率进行了评估。本研究的目的是探讨合肥髋部骨折的发病率和流行病学，并与其他人群进行比较。所有髋部骨折记录均来自合肥医院出院登记处的≥50 岁人群，并限于颈型或转子间型。将髋部骨折的发病率标准化为 2010 年世界人口。研究期间共记录了 1518 例（≥50 岁）髋部骨折（628 例男性，890 例女性）。调整年龄后，1 年的发病率为女性 144/100,000（95%可信区间= 135-153/100,000），男性 97/100,000（95%可信区间= 85-109/100,000）。与 2010 年世界人口相比，女性标准化发病率为 151.7/100,000，男性为 98.2/100,000。髋部骨折患者的平均年龄为女性 74.5±10.1 岁，男性 71.9±11.9 岁。髋部骨折女性与男性的总体比例为 1.48:1（发病率）和 1.54:1（标准化发病率）。单纯跌倒占所有髋部骨折病例的 85%。与北京和其他五个大洲的近期研究相比，合肥髋部骨折的发病率较低，但与 90 年代初中国东北地区的城市相比，发病率较高。不同地理区域发病率的不平等可能是由于人口的城市化或预期寿命所致，但需要进一步调查来证实这一假设。我们还发现女性发病率高于男性。单纯跌倒可能是髋部骨折的主要损伤机制。
