WEDNESDAY, April 1, 2020 (HealthDay News) — Vitamin D deficiencies are associated with a lower likelihood of older patients regaining independent walking ability following hip fracture surgery, according to a study recently published in the American Journal of Clinical Nutrition<\/i>.<\/p>\n
Lihong Hao, Ph.D., from Rutgers University in New Brunswick, New Jersey, and colleagues evaluated associations between 25-hydroxyvitamin D (25[OH]D) concentration and the Geriatric Nutritional Risk Index (GNRI) on mortality (30-day and 60-day) and ambulation rates among 290 patients (mean age, 82 years) undergoing hip fracture surgery.<\/p>\n
The researchers found that overall, patients with higher 25(OH)D concentrations, compared with patients with <12 ng\/mL, had higher rates of walking at 30 days. Findings held for each 25(OH)D category: 12 to <20 ng\/mL (adjusted odds ratio [aOR], 2.61); 20 to <30 ng\/mL (aOR, 3.48); and \u226530 ng\/mL (aOR, 2.84). There was also greater mobility at 60 days among patients with higher 25(OH)D versus the reference group (<12 ng\/mL). Reduced mobility was associated with poor nutritional status at 30 days but not at 60 days. At no time point was there an association noted between vitamin D or GNRI and mortality.<\/p>\n
“Given the high prevalence of hip fracture surgery, and findings in the current study, addressing potential modifiable risk factors with treatment modalities to improve recovery should be explored in a future randomized controlled trial,” the authors write.<\/p>\n
