介绍流行病学观察表明，阳光照射是髋部骨折风险的一个重要决定因素。本生态学研究的目的是探讨纬度和髋部骨折probability.Methods之间的关系，髋部骨折的发病率和死亡率从文献检索和10年髋部骨折的概率计算骨折和死亡hazards.Results之间有显着的关联纬度和10年髋部骨折的概率。对于从赤道的纬度的每10度变化（例如，从巴黎到斯德哥尔摩），男性骨折概率增加了0.3%，女性增加了0.8%，男女合计增加了0.6%。根据人均国内生产总值（GDP）或人均移动的电话使用情况判断，经济繁荣与髋部骨折风险之间也存在显著关联。人均GDP每增加10，000美元，髋部骨折概率增加1.3%。纬度和髋部骨折的概率之间的关联持续调整后的经济繁荣指数，这些研究结果提供了支持的髋部骨折风险的全球变化中的一个重要作用，阳光照射。此外，有必要确定与社会经济繁荣相关的因素，这些因素可能为全球髋部骨折概率的变化提供机制。
Introduction Epidemiological observations suggest that sunlight exposure is an important determinant of hip fracture risk. The aim of this ecological study was to examine the relationship between latitude and hip fracture probability.Methods Hip fracture incidence and mortality were obtained from literature searches and 10-year hip fracture probability computed from fracture and death hazards.Results There was a significant association between latitude and 10-year hip fracture probability. For each 10 degrees change in latitude from the equator (e.g., from Paris to Stockholm), fracture probability increased by 0.3% in men, by 0.8% in women and by 0.6% in men and women combined. There was also a significant association between economic prosperity and hip fracture risk as judged by gross domestic product (GDP)/capita or the use of mobile phones/capita. A US $10,000 higher GDP/capita was associated with a 1.3% increase in hip fracture probability. The association between latitude and hip fracture probability persisted after adjusting for indices of economic prosperity.Conclusions These findings provide support for an important role of sunlight exposure in the global variation of hip fracture risk. In addition, there is a need to identify the factors related to socioeconomic prosperity that may provide mechanisms for the variation in hip fracture probability worldwide.
