Greater fiber intake was associated with a reduced risk for symptomatic osteoarthritis, but not radiographic osteoarthritis, according to results of a recently published longitudinal study.
“Such results support the current recommended daily fiber for older Americans,” Zhaoli Dai, PhD, from Boston University School of Medicine, and colleagues wrote.
Investigators used data from the Framingham cohort of 971 patients with osteoarthritis and data from the Osteoarthritis initiative (OAI) cohort of 4,051 patients with osteoarthritis. All patients were followed annually for 48 months and then assessed 9 years later.
Researchers found a reduced risk for symptomatic osteoarthritis in the highest quintile of fiber consumption vs. the lowest for the OAI cohort (ratio = 0.7) and for the Framingham cohort (ratio = 0.39). However, there was no association for radiographic osteoarthritis. – by Will A. Offit
