Incidence of falls, risk factors for falls, and fall-related fractures in individuals with diabetes and a prior foot ulcer.
OBJECTIVE
To describe the incidence of falls, risk factors for falls, and the frequency of fall-related fractures in a cohort of individuals with diabetes and a prior foot ulcer.


METHODS
A total of 400 individuals with diabetes and a prior foot ulcer were recruited from two western Washington State health care organizations and followed prospectively for 2 years. Diabetes, demographic, and health information was collected at baseline, 1 year, and 2 years. Data on falls were collected at baseline, 4 weeks, and every 17 weeks thereafter. Medical records were abstracted to confirm fall-related morbidity.


RESULTS
The average age of the study population was 62 years, with 77% male and 23% female. Approximately 32% had fixed foot deformities, 58% had insensate feet, and 76% had comorbid conditions. Of the participants, 252 (64%) reported at least one fall during the 2-year study period. The overall incidence of falls in this cohort was 1.25 falls/person-year (95% CI 1.17-1.33). For the 164 participants (41%) who reported two or more falls, a BMI >/=30 kg/m(2), the presence of one or more comorbid conditions, and insensate feet increased the risk. Two or more falls of any type were associated with a higher fracture risk. Although women were not at significantly greater risk for falls than men, their fracture incidence was 3.6 times higher.


CONCLUSIONS
Falls are very common in individuals with diabetes and prior foot ulcers. A small percentage of falls resulted in fractures. The risk of a fall-related fracture was significantly higher in women than in men. Increased attention to falls and fall prevention is indicated for diabetes care providers.
