Effects of TZD Use and Discontinuation on Fracture Rates in ACCORD Bone Study.

Context: In trials, thiazolidinediones (TZDs) increase fracture risk in women, but the effects of discontinuation are unknown.

Objective: The objective was to investigate the effects of TZD use and discontinuation on fractures in women and men.

Design: This was a longitudinal observational cohort study using data from the Action to Control Cardiovascular Risk in Diabetes (ACCORD) trial bone ancillary study.

Intensive glycemic control is not associated with fractures or falls in the ACCORD randomized trial.

Objective: Older adults with type 2 diabetes are at high risk of fractures and falls, but the effect of glycemic control on these outcomes is unknown. To determine the effect of intensive versus standard glycemic control, we assessed fractures and falls as outcomes in the Action to Control Cardiovascular Risk in Diabetes (ACCORD) randomized trial.

Research Design And Methods: ACCORD participants were randomized to intensive or standard glycemia strategies, with an achieved median A1C of 6.
