Hip fractures are a reliable indicator of osteoporosis. Despite their importance, few studies have assessed their epidemiology in Lebanon and the Middle East.
Hip fracture incidence rates in Lebanon approximate those of Northern countries, and show the same characteristics, particularly the exponential increase with age, higher incidence in women, and a recent trend of rate leveling in women but not in men.
A national database of hip fracture cases admitted to hospitals in Lebanon in 2007 was created. Crude and age-adjusted incidence rates were calculated at 5-year intervals for individuals over age 50. These rates were also standardized to the 2000 United States population, and compared to those of other countries. Projected incidence rates in Lebanon in 2020 and 2050 were also calculated.
A total of 1199 patients were included in the study. The crude annual incidence rate in individuals over 50 was 147 per 100,000 individuals, 132 per 100,000 males and 160 per 100,000 females, with a female-to-male ratio of 1.2. The age-standardized annual incidence rates (per 100,000) were 180 in males and 256 in females. Assuming unchanged healthcare parameters, the projected crude incidence rates for people over 50 are expected to reach 174 and 284 per 100,000 in 2020 and 2050 respectively.
Lebanese hip fracture rates are lower than Northern countries, but show many similar characteristics such as an exponential increase with age, a higher incidence in women, and clues of a leveling of rates in women but not in men. Numbers are expected to increase substantially in the coming decades.
Level IV. Epidemiological study.
髋部骨折是骨质疏松症的可靠指标。尽管它们很重要，但很少有研究评估它们在黎巴嫩和中东的流行病学情况。
黎巴嫩髋部骨折的发病率与北方国家相近，具有相同的特征，特别是随着年龄的增长呈指数增长，女性发病率较高，以及女性发病率趋于平稳而男性发病率没有变化的趋势。
创建了一个 2007 年黎巴嫩医院收治髋部骨折患者的国家数据库。计算了 50 岁以上人群每 5 年的粗发病率和年龄调整发病率。这些发病率还按 2000 年美国人口进行了标准化，并与其他国家进行了比较。还计算了 2020 年和 2050 年黎巴嫩的预计发病率。
共纳入 1199 例患者。50 岁以上人群的粗年发病率为每 10 万人 147 例，男性为每 10 万人 132 例，女性为每 10 万人 160 例，女性与男性的比例为 1.2。年龄标准化的年发病率（每 10 万人）分别为男性 180 例和女性 256 例。假设医疗保健参数不变，预计 2020 年和 2050 年 50 岁以上人群的粗发病率将分别达到每 10 万人 174 例和 284 例。
黎巴嫩髋部骨折的发病率低于北方国家，但具有许多相似的特征，如随年龄呈指数增长、女性发病率较高以及女性发病率趋于平稳而男性发病率没有变化的趋势。在未来几十年，发病率预计会大幅增加。
