Intensive Glycemic Control and Skeletal Health Study (ACCORD-BONE)

5. september 2012 opdateret af: University of California, San Francisco

Intensive Glycemic Control and Skeletal Health Study - Ancillary Study to the Action to Control Cardiovascular Risk in Diabetes Trial (ACCORD-BONE)

The purpose of the ACCORD-BONE Study is to investigate the effects of intensive glycemic control for type 2 diabetes (in ACCORD participants) on factors related to bone health, including, fractures, falls, and bone mineral density.

Detaljeret beskrivelse

Recent studies have established that type 2 diabetes is a risk factor for fractures, particularly of the hip, shoulder and foot. Additionally, type 2 diabetes is associated with a 50-60% increase in the risk of falling. The higher risk of fracture associated with type 2 diabetes is an important health burden for these patients. More frequent falls and perhaps reduced bone strength in those with diabetes are thought to be key contributing factors. The best approach to preventing fractures in type 2 diabetes is not yet understood. There is observational evidence to support our hypothesis that better glycemic control will preserve bone and reduce falls and fractures. The ACCORD-BONE study provides a unique opportunity to determine whether intensive glycemic control will prevent fractures, falls, and bone loss in older diabetic adults, which may lead to improved treatment and prevention in the future.

Foranstaltningsbeskrivelse
Tidsramme
Number of Participants With at Least One Non-vertebral Fracture
Tidsramme: Average follow-up of 3.8 years
The BONE ancillary study was initiated during recruitment for the main ACCORD trial. Beginning in January 2006, at the next annual visit participants were asked about the occurrence of any non-spine fractures since randomization. After the annual visit in 2006, participants were asked if they had suffered a fracture since their last annual visit. Reported fracture events were centrally adjudicated, based on radiology records, at the University of California, San Francisco (UCSF) with the adjudicators blinded to treatment assignment.
Average follow-up of 3.8 years
Number of Participants With at Least One Fall
Tidsramme: Average follow-up of 2.0 years
At each annual visit starting in January 2006, participants were also asked about falling: "In the last 12 months have you fallen and landed on the floor or ground, OR fallen and hit an object like a table or stair?" Those who answered "yes" were also asked how many times they had fallen in the previous 12 months.
Average follow-up of 2.0 years

Tidsramme
Number of Participants With > 2 cm of Height Loss
Tidsramme: 5 years
Standing height was measured according to a standard protocol at baseline and annual visits on all ACCORD participants. Height loss was compared by treatment assignment using linear mixed models with random intercepts and slopes. Treatment effects were captured by the interaction between treatment assignment and time. The proportions losing >2 cm of height during follow-up were compared using logistic models. This degree of height loss is associated with incident vertebral fracture with 94% specificity but only 28% sensitivity
