Rapid rise seen in Beijing’s hip fracture rate

An 82% increase was found in the hip fracture rate among women aged 70 years in Beijing based on hospital discharge data for 1990 to 1992 and 2002 to 2006, according to results of a study confirming the rising hip fracture rates in China.
The study also showed a 442% increase in hip fractures for women older than 85 years with similar increases for older men during the same time period, according to an International Osteoporosis Foundation (IOF) press release. The study was presented at the 2010 Asia-Pacific Osteoporosis Meeting in Singapore.
S. He and colleagues identified over- and under-reporting of fractures — whenever the reporting method or referral patterns changed — during the two time periods studied. They then made appropriate adjustments before calculating the hip fracture rates.
The data support the observation that hip fracture rates are rapidly rising in China due to a growth in the number of elderly people and more sedentary lifestyles, according to the IOF release.
Beijing’s population of those older the 65 years more than doubled and the ownership of automobiles increased from four to 18 automobiles per 100 adults during the time interval the investigators studied.
The study gives further evidence that the burden of hip fractures, long considered to be higher in Western industrialized countries and lower in Asia, is rapidly shifting from West to East, according to the release.
