To evaluate differences in the short-term relationship between weather conditions and the incidence of hip fracture in people aged 65 and over among two regions of Spain.
Hip fracture incidence was calculated for the years 2000-2008 for residents of Health Area 14 in Valencian Community (Mediterranean climate) and the "Mancha Centro" Health Area in Castilla-La Mancha (inland climate), Spain. The relationship between hip fracture incidence and weather was analyzed with a case-crossover design and explored in subgroups defined by sex, age, and fracture type.
In the inland area, a positive and significant tendency for hip fracture incidence was observed (annual increase: 1.5%) whereas in the Mediterranean area a seasonal increase of 9% was noted in autumn and winter with respect to spring. Weather conditions, especially wind, were significantly associated with hip fracture incidence: days with more frequent windy periods and/or a greater wind velocity were associated with an increase in hip fracture incidence of 51% in the Mediterranean area and 44% in the inland area.
Hip fracture incidence exhibits seasonal changes that differ between the Mediterranean and inland areas. The short-term relationship with climate, although similar in both areas, may partly explain these seasonal changes.
评估西班牙两个地区65岁及以上人群中天气状况与髋部骨折发生率之间的短期关系差异。
计算了2000 - 2008年西班牙巴伦西亚自治区第14健康区（地中海气候）和卡斯蒂利亚 - 拉曼恰自治区“曼查中心”健康区（内陆气候）居民的髋部骨折发生率。采用病例交叉设计分析髋部骨折发生率与天气之间的关系，并在按性别、年龄和骨折类型定义的亚组中进行探讨。
在内陆地区，观察到髋部骨折发生率呈显著的正向趋势（年增长率：1.5%），而在地中海地区，秋季和冬季相对于春季髋部骨折发生率季节性增加9%。天气状况，尤其是风，与髋部骨折发生率显著相关：有风时段更频繁和/或风速更大的日子，在地中海地区与髋部骨折发生率增加51%相关，在内陆地区与髋部骨折发生率增加44%相关。
髋部骨折发生率呈现出地中海地区和内陆地区不同的季节性变化。与气候的短期关系虽然在两个地区相似，但可能部分解释了这些季节性变化。
