Geographic variations in hip fracture rates across the nine US Census Divisions were examined using data for elderly Whites from the 1979-85 National Hospital Discharge Survey. Rates varied considerably and were highest in the West North Central Division where rates for females were 50 percent higher than the US rate. Reasons for the geographic variations in hip fracture rates are unknown but do not appear to be closely related to latitude or fall-related deaths.
利用1979 - 1985年美国国家医院出院调查中老年人白人的数据,对美国九个普查分区髋部骨折发生率的地理差异进行了研究。发生率差异很大,在西中北部分区最高,该分区女性的发生率比美国平均水平高50%。髋部骨折发生率存在地理差异的原因尚不清楚,但似乎与纬度或与跌倒相关的死亡没有密切关系。
