Taipei, November 15, 2014 - While a low body mass index (BMI) of less than 20 kg/m2 has been shown to be an independent risk factor for hip fractures, far less is known about the relationship of body weight changes on hip fracture risk.

The findings of a new study presented today at the IOF Regionals Asia-Pacific Osteoporosis Meeting in Taipei, show that among middle-aged to elderly Singapore Chinese, weight loss of 10% or more was associated with a 56% higher hip fracture risk.

The researchers used data from the Singapore Chinese Health Study, a population-based cohort of 63,257 Chinese men and women aged 45-74 years at recruitment (1993-1998). After an average of 5.7 years, the researchers conducted a follow-up interview (1999-2004) among 52,322 surviving subjects in the group studied.

A total of 775 incident hip fracture cases were identified from the follow-up interview until December 31, 2010 [interval of 9.0 years]. The mean age at hip fracture was 75.3 years.
