Better nutrition trajectory improves recovery following a hip fracture surgery for older persons with diabetes mellitus.

Abstract

Influences of nutritional status on hip fractured persons with diabetes mellitus (DM) following surgery have not been reported. To explore the trajectory groups of nutritional status and their influences on post-operative recovery for older persons with hip fracture and DM. A total of 169 patients with DM and hip fracture from a clinical trial were included in this analysis. Mini Nutritional Assessment was used to assess the nutritional status of the participants. Outcome variables included self-care ability, muscle strength, depressive symptoms, health related quality of life, and cognitive function, which were collected before discharge and 1-, 3-, 6-, 12-, 18-, and 24-months following hospital discharge. Among hip fractured older persons with DM, within two years following surgery there were three nutritional trajectory groups: malnourished (28.3%), at-risk of malnutrition (41.9%) and well-nourished (29.8%). A decline in nutritional status, especially for the malnourished group, was seen in the second year. A better nutritional trajectory was associated with better recovery outcomes, including self-care ability, health related quality of life, cognitive function and less depressive symptoms. Close to 30% of hip fractured persons with DM were considered to have a malnourished trajectory over 2years following surgery. A poor nutritional trajectory was associated with poor mental health and physical recovery. Continuous nutrition assessment during the first 2years following hip fracture surgery for older persons with DM is important. Development and implementation of interventions targeting the malnourished trajectory group are suggested.
