In the January issue of IDEA Fitness Journal (2014; 12 , 11), we reported on the significant increase in osteoporotic fractures among men in recent years. A new report shows that losing weight may increase hip fracture risk.
Using information from the Singapore Chinese Health Study, researchers looked at the health reports of 63,257 Chinese men and women aged 45–74 at recruitment. Over 5.7 years, 775 hip fractures occurred and the average age at hip fracture was 75.3 years. Comparing hip fracture statistics and body weight change data, the researchers found that participants who dropped 10% of their weight were 56% more likely to experience a fracture. Individuals who were over-weight at the outset of the intervention and lost 10% or more of their total body weight had the greatest risk of fracture. The scientists found no substantial risk of fracture among those who had gained weight.
“The results of this study suggest that doctors should be alert to the need to identify and manage the risk in patients who have experienced substantial weight loss,” warned the authors. “Hip fractures are a major cause of disability and premature death in seniors, and it is therefore important that preventive action be taken in patients who are at high risk.”
The study was presented at the International Osteoporosis Foundation Regionals Asia-Pacific Osteoporosis Meeting in Taipei, Taiwan. The abstract appeared in Osteoporosis International (2014; 25 [Suppl. 5]).
