A recent study published in Osteoporosis International sheds new light on the relationship between body mass index (BMI) trajectories during middle adulthood and the risk of bone fractures in late adulthood.
The study, " Association of bone fracture with 30-year body mass index (BMI) trajectories: findings from the Framingham Heart Study ," provides valuable insights into the potential implications of BMI changes on fracture risk later in life.
The study analyzed data from the Framingham Original Cohort Study, involving 1772 participants with an average follow-up of 17.1 years. BMI trajectories were constructed using latent class mixed modeling, and their association with fracture risk after age 65 was explored using Cox regression.
Key findings of the study include:
"These findings emphasize the importance of maintaining a stable BMI throughout adulthood to reduce the risk of fractures in later life," said Douglas P. Kiel, MD, MPH , Director, Musculoskeletal Research Center and Senior Scientist, Hinda and Arthur Marcus Institute for Aging Research, Hebrew SeniorLife; and Professor of Medicine, Harvard Medical School and Beth Israel Deaconess Medical Center. "For overweight individuals, strategies to avoid bone loss during periods of weight loss during middle adulthood could be beneficial in terms of reducing fracture risk. This is especially true with the recent increases in the use of the new obesity drugs. "
