Abstract
Weight loss is a risk factor for hip fractures but few studies have evaluated the effect of weight loss on distal forearm fracture risk In this longitudinal study including 7871 postmenopausal women weight loss of 5 or more was associated with an increased risk of distal forearm fracturesThe study included 7871 women aged 65 years or more in the NordTrøndelag health study HUNT in 1994–1995 HUNT II who also had their height and weight measured in 1984–1986 HUNT I Forearm bone mineral density BMD by single energy xray absorptiometry was available for 5688 women HUNT II Fractures sustained after HUNT II were registered during an average of 58 yearsA total of 536 women sustained a distal forearm fracture After adjustments for age and body mass index BMI at HUNT I women who lost ≥5 of their weight between HUNT I and HUNT II had a relative risk of fractures of 133 95 confidence interval 109 162 compared with the rest of the women The higher risk of forearm fracture among women with weight loss was at least partially explained by their lower forearm BMDThe study was supported by grants from the Norwegian Research Council The NordTrøndelag health study The HUNT Study is a collaboration between the HUNT Research Centre the Faculty of Medicine Norwegian University of Science and Technology NTNU Verdal the Norwegian Institute of Public Health and the NordTrøndelag County Council The fracture registration was performed by the NordTrøndelag Hospital Trust
