A survey of all fractures in patients > or =35 years of age for hip, distal radius, and proximal humerus was performed in Tottori Prefecture, Japan. Hip fracture survey was done for the years 1986-1988, and also 1992-1994. A distal radius and proximal humerus fracture survey was done for the years 1986-1988, 1992, and 1995. The age- and gender-specific incidence rates of these three types of fracture among Japanese were substantially lower than those of whites living in North America or northern Europe. The age-adjusted incidence rates of hip fracture (per 100,000 person-years) were 40.7 and 114.1 in 1986 and 57.1 and 145.2 in 1994 for men and women, respectively, showing a significant increase with time for women. Upon examination of individual fracture types, there was no significant increase in cervical fractures, whereas a significant increase was observed in trochanteric fractures for women. The age-adjusted incidence rates of distal radius fractures for women were 164.9 in 1986 and 211.4 in 1995, showing a significant increase with time; however, no increase was observed among men. Incidence of proximal humerus fractures was 10.3 and 42.0 in 1986 and 17.1 and 47.9 in 1995 for men and women, respectively, and these increases were significant for both genders.
在日本鸟取县，对年龄大于或等于35岁的髋部、桡骨远端和肱骨近端骨折患者进行了一项调查。髋部骨折调查涵盖了1986 - 1988年以及1992 - 1994年。桡骨远端和肱骨近端骨折调查涵盖了1986 - 1988年、1992年和1995年。这三种骨折类型在日本人中的年龄和性别特异性发病率显著低于生活在北美或北欧的白人。1986年男性和女性髋部骨折的年龄调整发病率（每10万人年）分别为40.7和114.1，1994年分别为57.1和145.2，女性发病率随时间显著增加。在检查个体骨折类型时，颈椎骨折无显著增加，而女性转子间骨折显著增加。1986年女性桡骨远端骨折的年龄调整发病率为164.9，1995年为211.4，随时间显著增加；然而，男性中未观察到增加。1986年男性和女性肱骨近端骨折的发病率分别为10.3和42.0，1995年分别为17.1和47.9，男女发病率均显著增加。
