LOS ANGELES – results from a large community-based study have shown.
“Osteoporotic fractures are a significant public health burden, causing high morbidity, mortality, and associated health care costs,” Elizabeth J. Samelson, PhD, said in an interview in advance of the annual scientific and clinical congress of the American Association of Clinical Endocrinologists. “Risk of fractures are higher in patients with type 2 diabetes. Further, outcomes are worse in type 2 diabetes patients, with greater frequency of complications following a fracture.”
Given the projected increase in type 2 diabetes in the U.S. population, Dr. Samelson, an associate scientist at the Marcus Institute for Aging Research at Hebrew SeniorLife and Harvard Medical School, Boston, and colleagues set out to evaluate the short- and long-term risks of bone fractures associated with the disease. They drew from 2,105 women and 1,130 men who participated in the Framingham Original and Offspring Cohorts and whose baseline osteoporosis visit was around 1990. Type 2 diabetes was defined as having a fasting plasma glucose of greater than 125 mg/dL or being on treatment for the disease. Incident fractures excluded finger, toe, skull, face, and pathologic fractures, and the researchers used repeated measures analyses to estimate hazard ratios for the association between type 2 diabetes, type 2 diabetes medication use, and type 2 diabetes duration and incident fracture, adjusted for age, sex, height, and weight.
The mean age of the study participants was 67 years, and the mean follow-up was 9 years. The prevalence of type 2 diabetes in women and men was 7% and 13%, respectively, and 63% and 51% of those were on medication for the disease. The mean duration of diabetes was 8 years.
Dr. Samelson and colleagues found that the cumulative incidence of fracture was 37% in women with type 2 diabetes and 30% in those without the disease. Meanwhile, the cumulative incidence of fracture was 11% in men with type 2 diabetes and 16% in those without the disease. The researchers also found that type 2 diabetes was associated with 1-year fracture risk in women (hazard ratio, 2.23), but not in men.
In the entire study population, longer duration of type 2 diabetes increased the 2-year fracture risk (HR, 1.28), as did the use of any type 2 diabetes medication (HR, 1.70). The researchers observed no statistically significant differences between type 2 diabetes and long-term incidence of fracture.
“Previous studies have contributed to understanding the higher incidence of fractures and worse outcomes in type 2 diabetes, [but] the current study demonstrated that patients [with type 2 diabetes] have 50% to 100% higher short-term [1- to 2-year] risk of fracture independent of clinical risk factors, whereas long-term [10-year] risk of fracture was similar in [patients with] type 2 diabetes and those who do not have [the disease],” Dr. Samelson said. “The current study has some inherent limitations of observational studies, including a lack of definitive determination of causality and that the results are not generalizable to patients with similar demographics. The study, however, is robust in the availability of detailed clinical information, which allows for control of multiple confounding variables.”
