Women in China have much lower risk of hip fracture than women in Europe or North America but their risk of vertebral fractures is not known. Lateral spine radiographs, hip and lumbar spine bone density, and potential risk factors for and consequences of vertebral fractures were assessed in a random sample of 402 women age 50 years or older living in Beijing, China. The prevalence of vertebral fractures, defined by vertebral morphometry, increased from 5% (95% CI, 1-9%) in 50- to 59-year olds to 37% (27-46%) among women age 80 years or older. The age-standardized prevalence of vertebral fractures was 5.5% lower than found by similar methods for women in Rochester, MN, U.S.A. Each SD lower spine bone mineral density (BMD) was associated with a 2.4-fold (1.7-3.5) increased odds of having a vertebral fracture. Women with a history of heavy physical labor had a lower risk of vertebral fractures. Vertebral fractures were associated with decreased height loss and limited physical function but not chronic back pain. Women in Beijing, China have lower bone density and a slightly lower rate of vertebral fracture than white women in the United States. Low bone density and more sedentary occupations increase the risk of fracture in women living in urban China.
